Week 2: 24 minds are better than one

I wouldn’t necessarily call myself a lone wolf, but I’m definitely an independent worker by nature. Years of struggling through group projects with unmotivated high schoolers taught me to trust no one’s work ethic besides my own. Asking for help or input was out of the question; if I wanted it done right, I had to do it myself. 

As I’ve come to learn at Rice, this is not a sustainable mindset, especially for an engineer. And given that study groups were my saving grace during my sophomore year of college, I’m ever so slowly learning to trust and even lean on my teammates. This week, as we began our daily Morning Standup sessions (in which each team will share any progress or struggles encountered the previous day and ask for suggestions from their peers), I discovered the true meaning of the phrase, “two minds are better than one.” 

During our research phase of the design process, we hit a wall in terms of finding materials for the device which are both durable and locally sourced in the countries we are designing for. After spending hours the week before racking our brains for ideas, I shared this struggle with the group during our inaugural Morning Standup and mentioned that any suggestions would be greatly appreciated. 

The response was immediate–several people asked questions to clarify our problem (What are the requirements of the structure? What effect does UV light have on materials?), then suggested that we talk to our international collaborators or consider pre-built structures such as containers used in shipping or construction. I was even approached afterwards by my peer Matthew, who mentioned using foil warming blankets to contain UV light within the device, and our TA Andrew, who pointed out that the Steribox does not have to be a box

I was like a horse with its blinders removed. Of course–names are important, but they don’t have to define our device. Our team excitedly discussed a variety of new geometries: a cylinder, a triangular prism, or even a frame with UV-blocking fabric draped on top (I’ve shown a couple of brainstorming ideas below; please ignore my excited [messy] handwriting). We had spent so much time focused on the specifics of our project that we didn’t even think of zooming out and taking a different approach to the problem.

 

Now, five Morning Standups later, my teammates and I rack our brains for obstacles to share each time just so we can take advantage of the collective brainpower of the 24 interns, TAs, and instructors in the room. Moving forward, I’m excited to continue building my trust for my teammates and appreciating the value of humility and collaboration. Who knew that roadblocks could be the most promising part of the process?

***I thought I’d also take a moment to share some exciting news: after 1.5 weeks of deliberation, we’ve named ourselves Team Now UV Me, Now U Don’t! I’ll leave you with a team picture–not just any team picture, but a groundbreaking hybrid team selfie.***

Week 1: Reflections

Hi everybody! My name is Chinwe Appio-Riley and I am a new graduate. I studied Kinesiology, Engineering Design, and Global Health Technologies, and I am super excited to be here at Rice just a little bit longer by taking part in the SEED/Rice 360 internship this summer! This whole experience has been completely new to me as my background really isn’t on the bio side of things but I’m really enjoying it so far! I am a part of Team Breath Easy aka Breezy, along with my teammates Alvin, Alois, and Matthew. We are working to create a Bag-Valve Mask Monitor.

A BVM is an elastic bag with two one-way valves and a “mask” to fit over the patient’s nose and mouth. This is used by Emergency Medical Technicians (EMTs) and paramedics when a person is severely injured or sick that they have lost the ability to breathe on their own and is often used in emergency situations on-site. It is the simplest way to help a person in severe respiratory distress. It is not as good as the care you can get in an ICU, but it can save your life.

The problem is that it is possible to squeeze too hard and deliver too much air and damage the patient’s lungs. This is especially true if the EMT is highly stressed (which is common), or has pressed an untrained volunteer into service to help other, even more badly wounded, patients. Based on its work with flow sensors for emergency pandemic response ventilators, Public Invention had a simple idea: use a flow sensor to measure how much air is delivered and give guidance to the user. The idea is to have a machine that assists, either visually and/or auditorily, with the frequency and volume of pumping.

An ENGI 120 group has been able to produce a mid-fidelity prototype that we are iterating on. We need to make the device more portable, durable, and easy to use. I am specifically involved in the easy-to-use portion of the device due to my background in human-centered design and understanding of the human body. I am excited to implement what I’ve learned about Human Factors which is a scientific process to reduce human error, increase productivity, and enhance safety and comfort with a specific focus on the interaction between a human and the thing of interest.

This past week, we have reviewed the beginning part of the engineering design process of contextualizing the problem and developing ideas for solutions. Additionally, we have engaged in workshops to aid in team dynamics and communication. I have found several of these exercises extremely useful and have put me in a reflective mindset to check my interactions with my teammates. I find that often I struggle to actively listen in lengthy and rambling dialogues and lectures. Often I want the discussion to get the point which results in me getting inpatient. Thus, my listening drops off. What I do to combat this is to keep an objective to try and understand what the individual is trying to say in order to rephrase back to them to make sure that we are on the same page. This keeps me more engaged and keeps the discussion more productive.

Another tool in keeping meetings on track that I am working to refine is the wonderful meeting agenda. We had a wonderful presentation from the RCEL team to review how to structure and organize team and client meetings. I used meeting agenda’s all the time in my capstone project during the school semester. Therefore, I am well acquainted with this concept, however, what was new was the idea to predict and take into account how long each objective will and should take to discuss. This way you can project how long a meeting might take in total.

Up next, the team and I are excited to engage in user interviews and finish creating design criteria and screening ideas so that we can jump into the prototyping phase.

Week 1 Reflections

Content warning: My project deals with pediatric sexual abuse. Please take care of yourself while reading this blog.

Going into this internship, I was very excited to be able to work on an impactful project with amazing and talented people from a variety of backgrounds. This first week has truly made that a reality! As someone who has engaged in a variety of extracurriculars related to social justice and human-centered design, I’ve always really enjoyed opportunities where I’ve been able to work with groups with a clear broader purpose of helping make this world a better place. That’s the amazing thing about working on global health projects: we all share the common goal of improving health access and equity. Additionally, this internship and the Rice 360 Global Health Department as a whole have really emphasized from the beginning the benefits of a wide range of perspectives in designing truly sustainable and efficient solutions to these complex design challenges we wish to tackle. That’s why it is so exciting and welcoming for me, a Social Policy Analysis and Economics major to take the Global Health Technologies minor and work with many people from more technical engineering backgrounds in a collaborative setting, because we really learn a lot from each other.

When choosing a project, my main goals were to find one which aligned with my interests, where the social context was a key component of the design challenge, and which would have a large impact on the current status quo. All of the projects this year are exciting and important. I ended up choosing the pediatric pelvic model project, in which my team will work to develop a model for use in training nurses to conduct pelvic exams for pediatric sexual assault survivors. This is an important step of the process following the report or reasonable suspicion of pediatric sexual assault, and is a key component to making sure these survivors get the proper care they deserve. Our team is working with Ms. Nancy Harris, the TeleSAFE Director of Operations at United Concierge Medicine and director of forensic examiner nurse trainings in New York. She is very passionate and knowledgeable about this space and this project in particular. One thing that makes this project very exciting to me is the huge need for better training models and we will really be paving the way for something new. There are few professionals in this field and no currently available hands-on training models for training nurses, resulting in prolonged training periods. Although this is a very heavy project topic, our team has received overwhelming support from each other, our TAs, our internship leadership team, and our client. Everyone working with me has made it feel like a safe space to work on such an important yet emotional project, making it feel like a very supportive atmosphere. This sort of emotional awareness and support is truly crucial to working on a team project, especially with such a topic like this, and I very much appreciate everyone I’m working with.

This past week with the project we have been working on doing background research into the problem space, similar solutions, and potential materials. Additionally, we had a preliminary meeting with our client, who was very helpful in clarifying the need for and logistics of the project and is very supportive of our team. The internship programming included workshops to help us get familiar with the stages of the engineering design process and some prototyping tools. We built birdhouses in order to gain basic experience in hand tools. Our team, which consists of myself, a junior from Rice University, Shivani and Shannon, both sophomores from Rice University, and Alex, a sophomore from the University of Texas at Austin, has also done some bonding over the past week, including going to dinner together after work. It has been really great working with such passionate and interesting people from various backgrounds! I’m looking forward to diving deeper into design details and brainstorming how to make this design project come to life and be able to make a huge change!

Week 1: New Beginnings

Content warning: My project deals with pediatric sexual assault.

Hi everybody! My name is Alex Natelson and I am a rising sophomore majoring in aerospace engineering at The University of Texas at Austin, but I am super excited to be taking part in the SEED/Rice 360 internship this summer! This whole experience has been completely new to me as my background really isn’t on the bio side of things but I’m really enjoying it so far! I am a part of Team PIPER, which stands for Pediatric Instructional Pelvic Exam Resource, along with my teammates Elise, Shannon, and Shivani.

 

So far a lot of this process has been education-based with us spending a lot of our time doing background research on this topic since we aren’t all that familiar with it. We were able to speak with our client, Nancy Harris, and pick her brain on all of our concerns and questions surrounding this project. She really helped us out by giving us some resources to go off of and helping us to refine our research into one specific aspect of pediatric assault, the post-assault pelvic exam. This exam is what our project is intended to help make more clear in making a pelvic model for nurses to train on. All of the first week was spent doing workshops on problem evaluation and research, and then conducting that research.

 

This week, we have focused more on design criteria and brainstorming. We had a couple of workshops on designing for clients and usability, and my team has been working hard to identify what we need to include in our model. This has been a little more difficult for us, since we’re working almost from scratch, so we have to consider a lot of factors in our design. We have a good amount of design criteria right now, so we’re working on narrowing those down and combining criteria into full solutions. I’ve had an amazing time so far getting to know everyone in the internship, and I feel like everyone is really starting to bond now so I can only imagine how close we’ll be at the end of this. I’m super excited to continue my work with my team and I really hope we can make an effective solution!

Week 1: Pterodactyls and 1600 Lines of Code

Intro

When I arrived at the OEDK at 9am on Monday, the most exciting thing as I walked through the doors was seeing everyone’s faces. Since then, we have had in-person workshops with speakers and every day I’ve been able to sit at a table with my teammates, or lean over a circuit in the elec lab. This is the first Rice experience I’ve had unmasked and indoors, and so far it’s been incredible.

On Tuesday, everyone came into the classroom eager for their project assignments. The day before, I had sent in a ranked list of my choices, and fortunately, I got my top choice–– the portable field incubator. The goal is to develop a portable way to incubate water samples at body temperature in low resources settings to determine if water is safe to drink. There had been three previous iterations of this project, a senior design project, Minicubator; a freshman design project, Moonrats; and Public Invention, which is where our client works, had a project which was also called Moonrats. Our team is working on taking the best of the three prototypes and designing a device that works, is user friendly, and logs data.

After project assignments, my team had a chance to get to know each other and make the most important decision–– determining our team name. We had many ideas, ranging from ‘Clean Mean Incubation Machine’ to ‘Mars Beavers’, but eventually we decided on Petri-FI. Petri film is what must be incubated after a water sample is added to it, and FI stands for film incubator. For those of you who don’t know, the similarly-spelled Petrie is the name of a pterodactyl from the 80s children’s movie, The Land Before Time.

Naturally, he became our team mascot.

Speaking of the team, here we are on the steps of the OEDK!

Technical Stuff

We started out researching the basics and looking at previous team’s projects, including comparing the code from Minicubator and Public Invention and examining the freshman Moonrats team’s prototype. We also met with our client twice to find out what his expectations for the project were. Going forward, we plan to start with the code and electronics from team Minicubator but replace the insulated chamber they built, which was basically a 3D printed box full of insulation with a smaller 3D printed box inside it for the Petri films, with a standard wide-mouth thermos.

This week, we received the project description and began researching the project. We also reached out to the faculty advisors from the previous two teams: senior design team ‘Minicubator’ and freshman design team ‘Moonrats’. We went through the prototype that team Moonrats left us, and looked through the code, PCB design, and demo videos from team Minicubator. From what we can tell, their code is fairly robust and well-written. We compared it with the code on Public Invention’s Moonrats GitHub repository, and for the most part, the code does the same thing, but we have found a few significant differences, outlined below in Table 1. 

Table 1: Differences between PI Moonrats and Minicubator Arduino code. 

PI Moonrats Minicubator
Hard-coded in places, sparsely commented Well-commented and good use of variables
TMP36 Thermistor
EEPROM storage code No EEPROM storage code
Graphing capability Minimal graphing
Complex button decoding Fewer menu options
Timer interrupt No timer interrupt

 

We have decided to start working from the Minicubator code, mostly because it is clearly commented and does not have many hard-coded settings, unlike the Moonrats code. We also decided that the thermistor is better than the TMP36, and that the EEPROM storage code is unnecessary if we can find a way to utilize a micro-SD slot underneath the display screen. Eventually, we may also want to add a graphing feature of all the temperatures in the incubation period, like the one from Public Invention, but for now we will consider this low priority. In terms of the menu, we will probably try to program in more options, but ideally we will not make the button system as complicated as it is in the Moonrats code. We have not yet made a decision on the timer interrupt issue.

On Monday, we will get Minicubator’s prototype. Once we have this, we can test the functionality and get a better idea of what we should focus on improving. Specifically, there are some aspects of the PCB design on Fusion 360 that are confusing, and having the physical board will probably clear up those issues. We also have some tasks broken down by team member for the beginning of next week. My job is mostly to focus on hardware and wiring–– I need to cut the wires going from the nano into the heating element and solder six jumper headers onto each end, so that it is possible to unplug the device as the lid is removed once we transfer to a thermos-based system.

Future

I am really excited to work on more of the hands-on hardware issues, especially in terms of combining three prototypes into one. I think my biggest challenge will be to make a circuit I can keep adjusting, probably using a breadboard, from the outsourced PCB that Minicubator left us. I expect to spend a lot of time in the elec lab next week! As a side note, this week I also decided to switch my major–– previously it was electrical engineering, and now I’m planning to do mechanical engineering. I’m really glad that even though I’m moving away from hardware overall, I will still have plenty of opportunities to pursue my interests in electrical engineering throughout this project!

Week 1: Lights Out

Just over a week ago, I made the solo 9-hour drive from my home in Arkansas to Houston. It was fast-yet-slow in the way that car rides tend to be, especially when your eyes are on the road instead of the endless scenery around you. Listening to a variety of albums, I had plenty of time to consider the purpose of my return. In just a few hours I would be unpacking my things, and in a few days I would be sitting in a room with about two dozen other interns in the OEDK, ready for a summer experience like no other.

And, just as my imagination would have it, there we were. Dispersed in the OEDK classroom at 9:00 AM. As people engaged in scattered conversation, there was a latent energy in the space. Today was mostly introductions and formalities, but tomorrow, we would get our assigned projects, and our assigned team members. Today we could take our deep breaths, but tomorrow we would jump into the deep end of our engineering projects, with team members we haven’t even met yet.

The Project

When I heard the first project description, I was scribbling my notes in cursive, trying to get all the details. I thought, “Yep, that’s the one I want.” Then, the next project was described, and the next, and each one seemed to get even better than the one before. When I was picking my project preferences, it took me a great deal of time to order my top three, because they all seemed like amazing opportunities. I finished the first day of the SEED internship flush with excitement. Tomorrow was a day that, however ordinary, would determine my fate for the next six weeks.

I was ecstatic. Of course, I knew that I would like one of my top three projects, but now the project felt like mine. After meeting my teammates, I knew that this was going to be a fun time. We started by studying our challenge:

In many regions of the world, it can be difficult to acquire safe, clean drinking water. This can be a cause of waterborne illness, which affects large numbers of people worldwide. One way to help communities experiencing this is by testing water for E. coli, which is a bacterial indicator for fecal contamination. However, proper incubation of petri dishes or petri-films for E. coli requires a constant temperature of 35-37 degrees Celsius for up to 48 hours, and typical incubators are very large, cumbersome, and require AC power, which can be unreliable in certain areas of the world. Therefore, our client sought a portable, battery-powered field incubator for Petrifilm, which could hold the optimal temperature for growing E. coli over 48 hours. Our newly created squad, which we named Team Petri-FI, was tasked with improving the prototypes of previous student teams by making the device more portable and functional. We were off to the races.

Excitement Builds

To begin our project, we began the process of reading client documents and performing research to learn more about the incubation of E. coli. We compiled a document with as many sources as we could find about how water testing was performed, and how E. coli related to the problem of waterborne illnesses. On the more technical side, we also researched how incubators maintained their internal environment and looked into control units, such as Arduinos, for managing the temperature inside the device. By the end of Wednesday, we were bursting with hypothetical ideas, and we were itching to talk to our client so that we could gain a strong sense of direction for our project.

On Thursday afternoon, we met with our client over Zoom. In particular, we were able to hear about the motivation behind the project. Our client gave us extremely useful context for our design challenge, and it helped us to think more clearly about the goals of our design. When we zoomed back to the problem as a whole, it is quite amazing that we as students can contribute to solving problems like these in low-resource areas. Toward the end of the week, we had learned enough about our project to know that it would be a great challenge for this summer, but Team Petri-FI is more than prepared to roll up our sleeves and tackle it head-on.

On a more personal level, I saw great potential in this project to develop skills that I have wanted to improve for a while. Although I have focused much of my energy into studying mechanical engineering, I have long been interested in programming and computer science. I have written hundreds of lines of code, either in competitions or just for myself. However, this will be the first time that I have a chance to see my code manifested in the real world. I have not worked with an Arduino before, but I am excited to apply my knowledge of coding to the physical challenge of maintaining temperature inside an incubator and recording important information from the device. Furthermore, I will also get a chance to develop and build the circuits that will make our prototype function. Overall, this project is a large step out of my comfort zone, but I am excited for the opportunity to learn new skills over these six weeks.

The Bat House of Bonding

I experienced an unexpected highlight of the week during the hand tools workshop, which was designed to teach us about the hand tools in the OEDK. This workshop was made more interesting by the fact that we were split up into random teams to construct wooden bat houses with some drawings and our newly-acquired knowledge of hand tools. Although our team’s members did not yet know each other well, we embarked on our mission with unparalleled camaraderie.

As many things do, this task quickly became a competition with the other teams. Even though we took longer than other teams to cut our wood, our patience gave more time for creativity to blossom within us. We clamped wood, drilled holes, fastened pieces together with screws and nails. Finally, we had erected our structure, a modest bat house with more than a few mistakes. That was our only assigned task; however, we saw an opportunity to smooth out the edges and create a work of art. Unprompted, our team gathered sand paper and brought the coarse plywood to a smooth finish with our hands. Then, we wood-glued a piece of scrap wood onto the front as a nose, realizing that it would be a shame not to paint the bat house to commemorate our hard work.

The next day, we discussed our vision for the final paint design, inspired by the long wooden nose glued to the front of the bat house. Upon returning from Team Petri-FI’s client meeting, I was greeted with by work of art at the OEDK: Pinocchio himself!

This exercise taught me some things that I’m glad I learned in the first week of the SEED Internship. First, never underestimate the artistic talent of your teammates, because they will often surprise you. Second, it is extremely rewarding to push beyond the expectations and boundaries of the tasks we are given. With just a little extra time and a brilliant vision, our team chose to go beyond the expectations, for only our own satisfaction. Experiences like this remind me to always be learning and pushing the boundaries of my own knowledge, because it just might lead me to create new and exciting solutions to the problems I face. I am extremely thankful to my teammates for choosing to put their best effort into this mini-project, and I’m glad that I was able to share this memory with them.

Week 1

Hello all!

My name is Alvin Ibeabuchi and I am so exited to be a part of the Rice 360/SEED collaboration this summer. Here with Rice 360, I feel more than welcome. During the first week, I have had the pleasure to meet wonderful new people. I got to attend informative workshops amazing leads.  I also was given the opportunity to work on a project that can better my skill set as an engineer while potentially impacting someone’s life.

I am blessed to be on a great team with an enthusiastic and interesting client, Dr. Robert Read. My team will be working on the Bag Valve Mask (BVM) Indicator. This project entails many different skill sets that I would love to develop and learn such as CAD, coding, electronics, and UI/UX. I look forward to completing this project and enjoying this experience. This is going to be a great summer!

Week 1: Goal Setting

Hi! My name is Teja Paturu and I’m a rising senior at Rice University and this summer I am so excited to be working at the OEDK through the Rice 360 summer internship over the next few weeks. I am a Biosciences major with a concentration in Cell Biology & Genetics and have a minor in Global Health Technologies. Throughout my years at Rice, I have crystallized my passion to the intersection of engineering design and medicine to serve those who are underrepresented and under-resourced. As such, alongside this internship, I am applying to medical school so that I can bring the engineering design process to a long-time life goal of mine to be a physician. 

This summer I am working on a field incubator so that field engineers can test sources of water for safety. Water-borne illness kills 829,000 people each year– all preventable deaths with access to clean water. Diarrheal disease, typhoid, bacterial dysentery, and cholera are just some of all of the burden of disease sourced from access to clean water. WHO even estimates that these numbers are conservative claiming that only 5-10% of annual cases are reported officially. To reduce and better quantify the burden epidemiological surveillance, laboratory resources, and testing infrastructure must be accessible to low-resource area where the burden is the highest. 

However, in many areas without access to water, there is also in-access to laboratory testing, particularly water incubation tests to identify e. coli contamination which is a hallmark of other pathogen contamination. Therefore, my team, Nancy, Kenton, Sara, and I are working on a field incubator to increase access to this testing. We are not, however, starting from scratch: we are starting from 3 prototypes each with benefits and drawbacks. Our goal for the summer is to splice together the best of the prototypes and also add some features to make the device suitable for the widest range of use. As such, this past week we have worked on drafting some design criteria, or goals, for our device over the next 6 weeks: 

Criteria Description
Safety The device should have no risk of shorts, no exposed metal of wires. No risk of dangerous electrocution from water.
Battery-Powered The device should be independent of a power grid. 
Portability The device should weigh ≤ 5 lbs and should be ≤ 0.5 ft3 in volume. The longest dimension should be no longer than 18in. 
Temperature The device should hold up to 37 degrees Celsius for 48 hours, in environments > 4 degrees Celsius.
Informative Records data at intervals. The display shows the current temperature and also a temperature log for previous and current cycles. Should be able to record data for > 48 hours
Intuitive UX Users are able to accomplish the following tasks easily– a subject can perform the following functions in < 3 minutes each

  1. Start incubation period
  2. Adjust temperature and duration
  3. View history of temperature by different intervals (several hours to full incubation cycle)
Housing Integrity The device should be durable–– if it is dropped 50 times from a typical trunk height it should still be operational.
Aesthetically Pleasing There should be no messy wires, and the device should have an aesthetically pleasing exterior.

To conclude, the first several days of the internship have been so exciting! My personal favorite part of these days has been meeting all of the interns and learning about their diverse backgrounds, so I encourage you to check out www.rice360.rice.edu/intern-blogs and read through the interns’ first posts as well– you will find a great plethora of very talented, interesting, and accomplished individuals!

Reflection on Week 1 Experience

My first week was exciting and  I am proud of the people I will be working with. This summer I will be developing a Bag Valve Mask monitor which gives feedback to the user to prevent both under ventilating and over ventilating a patient. My client is Dr. Robert Reed, the founder of the Public Invention. I look forward to this because I will improve my knowledge in coding, CAD and electronics.

Week 1: Making my Heart Beat

Hi, my name is Rachel Lee. I’m a rising sophomore studying bioengineering and this summer I will be a SEED intern at the OEDK. 

I had taken ENGI 120, a freshman design course meant to give students an introduction to the engineering design process, and saw SEED as a chance for me to focus entirely on a project without the added burden of classes and extracurriculars. 

This first week, we were assigned our projects and quickly jumped into clarifying the problem context. Our team (Team Heartache), composed of my teammates Kaitlyn, Christopher, and Sam, is tasked with developing a device that will mimic lung-heart motion. Our clients are a team of engineers from the Electrophysiology Clinical Research & Innovations department at the Texas Heart Institute. Due to our close proximity to THI, we were able to meet our clients in person. Upon arriving, we were shown the current prototype and quickly realized that this project had pivoted sharply from the original direction the ENGI 120 team from last semester had taken. My excitement grew as I continued to talk to the engineers at THI. They were so knowledgeable and delighted to help. 

For the next coming weeks, I will go through the engineering design process once more, but I will have more time for the “fun” stages, like prototyping, testing, and iterating over and over. This week was over before I could blink, and I can already tell that these six weeks will fly by. 

Excited for what’s to come,

Rachel Lee
