Hey everyone! This week has been packed with meetings, workshops and design analysis for our project. Despite how busy it was, the week seemed to fly by quickly. We met with members of the senior design team who worked on this project last year, Team EPIWATER. To prepare for the meeting, we read their final report (which is almost 90 pages long!) in addition to all their documentation in their Team Drive. Even though it was very time consuming, it was very informative and helpful for our team to understand our role in the project. It was really cool to learn about how they went through the design process when we met with them and why they made certain choices for the project. I also thought their team was an inspiring example of how successful interdisciplinary teams can be. 

After meeting with other people, such as Dr. Fowotade, a distinguished clinical virologist at the University of Ibadan, and Zach LaTurner, a PhD student at Rice, our team decided we were ready to move forward in the design analysis stage. We decomposed our design challenge problem into ten different functions aspects and used that information, along with our project research and client needs, to come up with our design criteria, which we then ranked using a pairwise comparison chart.

Ranked Design Criteria:

1. Sustainability: Durability of time sustainable energy source can power the device
2. Durability: Ability to withstand dust and rain and various stress/crash tests
3. Maintenance: Accessibility of device to be repaired easily
4. Portability: Dry weight and volume restrictions
5. Ease of Use: For setup and operating the user interface
6. Replicability: Ease of recreating the device 
7. User Interface: Monitored controls display values from sensors to establish recording

While these rankings are preliminary and may change based on further discussions and client meetings, they give us a good idea of what our team needs to focus on this summer. I had never done a problem decomposition before and initially didn’t fully understand how it relates to moving forward in the design process. However, it turned out that the design criteria that we chose and how we ranked them was informed by our decomposition. Even though we haven’t started brainstorming yet, I can already see how it will make that process simpler because we can break down our ideas based on specific design blocks. 

In addition to working on our project, we also has several workshops throughout the week. The morning workshops focused primarily on the design analysis stages, which was a good refresher. My favorite activity from those workshops was during the brainstorming workshop when Mr. Fletcher asked us to come up with non-solutions a.k.a ideas that don’t address the purpose of a product; hearing what my colleagues and I wrote at the end was hilarious!

We also had two workshops from Associate Dean Catherine Clark on difficult conversations and microaggressions. She emphasized the importance of having difficult conversations and gave us strategies on approaching them, which I think will be useful in both my personal and professional life. She also discussed the prevalence of microaggressions and how they’re perpetuated and how they can be harmful, despite being unintentional. This workshop was very impactful and reminded me to be aware of my biases and recognize them so that I can stop myself from saying something that could hurt someone else. 

This week was a rollercoaster from start to finish. This week we spent a lot of time in technical and interpersonal workshops, refining design criteria, and actually prototyping! Overall, the week felt very productive and I am confident that we managed to set up a deep understanding of our problem space and direction for the upcoming weeks. Some of the workshops we had covered things I would initially have thought were more relevant to personal development rather than a technical design project based internship, such as how to have difficult conversations and microagressions. I thought these workshops were teaching us things that were only minimally relevant in comparison to other technically relevant topics. But soon after the workshops I realized they protect one of the most valuable things that we are getting from this internship: our relationships, connections and workability with other people in the community.

This week, we made three different sizes of the kinetic hand model from the e-NABLE network, as suggested to us by Arinze. After our hyrdocal cast model from the previous week came out extremely still damp and crumbly, we knew we would have to meet up with Eric Jr. again to recast. After running another test mold, we developed a much better process to follow for our meeting on Friday. A lot of the changes we made were common sense, and came from spending a little more time reading the instructions on the container. I realized, even though we had done a little bit of research and experimentation, in our rush to move onto prototyping and researching, we ended up having to spend even more time on it. Next time it would be more time efficient to spend a little bit more time planning something initially the first time to prevent possibly having to redo it later. We learned how to 3D print with different materials such as PLA, TPU, and ninja flex.

Our week closed with another meeting with Eric Jr., his father, grandma and two younger brothers. His father reiterated to us the hand was to be used specifically for basketball rather than daily life. His philosophy in doing so was that in having been born with one hand, Eric Jr. wouldn’t become more efficient with two hands in the same way that we, born with two hands, wouldn’t know how to use a third. This comparison definitely helped spark understanding and thoughts of why we feel the need to “modify” differently abled people to get as close to “normal standard as possible.” This meeting also gave us some extra insight into our models and what and where we would need to iterate the following week. We learned that the 60% size was the closest fit, and that the hand would need extra reinforcements to protect and strengthen his wrist on his left hand. Additionally, we reaffirmed our thoughts of moving the thumb out of center and more to the side in an open hand position. Overall, meeting Eric again was such a delight again and has fueled me once again to get him the best prosthetic possible by the end of this internship!

This week went by so quickly! After meeting with our mentor Jackie last Friday, we got to work making a spreadsheet of questions for the Rice360 Fellows. With Jackie’s help, we were able to refine and rephrase our questions, and they were ready to be shared with some Fellows by mid-week. We met with Josh and Sonia to hear about their clinical experiences at Queen Elizabeth Central Hospital (QECH) in Blantyre, Malawi. Their insights have been extremely valuable, and have definitely helped us gain a clearer understanding of the existing issue and demand for a solution. Aside from conducting interviews, we continued compiling information by researching UVC sanitization, implementation of wireless charging, available power resources, and similar existing solutions. While we brainstormed broad form options, we outlined potential design criteria and considered how to rank them moving forward. 

In addition to our ongoing background research, it’s been a very workshop-intensive week. I’ve been able to learn many new skills, including breadboarding and 3D printing using Fusion. I particularly liked Lady Catherine’s workshops on microaggressions and having difficult conversations. Since the internship started, I’ve been looking forward to these workshops so that I can expand my skill set in engineering topics, and learn new concepts that I might not come across in my typical coursework for the Health Sciences major. 

Our main challenge this week has been balancing various components of the internship – with all the important workshops scheduled for this week, we had less time to work on our project. However, we were still able to make progress in our research. Next week, we hope to reach out to additional contacts to hear their insights, including previous Rice360 teams with similar designs regarding backup energy sources and UVC usage. I’m looking forward to our upcoming low-fidelity prototyping workshop, as well as our group social at Bayou Bend. Until next week! 

Hello everyone! It’s hard to believe that I have ended my 2nd week of the internship. It is incredible to think about how fast time flies when you are engrossed in whatever you are doing. This week, my team and I took time to think through the logistics of our project in preparation for low-fidelity prototyping during week 3.

At the beginning of the week, we developed a set of design criteria for our project. The design criteria are the targets and goals that will define the characteristics of our design. We developed these goals by first defining the basic user needs of our project such as safety, ease of use, durability, appearance, etc. We then categorized these user needs by whether they were constraints and objectives. For the more quantitative user needs, we developed quantitative target values for each criterion, and for the qualitative objectives, we designed user-defined scales.

After developing our design criteria, we then took our project idea and decomposed it into parts. Specifically, we first broke the design idea into the joints that we have to model. We then further decomposed each joint into the movements that they have to properly simulate for the Ballard Assessment. Building our design criteria and decomposing our project idea into the specific components/details helped me develop an idea of the scope of our project and the aspects that need to be addressed. A concern that I had during week 1 was just how big and complex our project looked from the outside. As someone who does not have any sort of engineering background, the idea of having to design a model that can perform these complicated physical motions was overwhelming, but having the opportunity to firmly establish what this model needs to have characteristically and what are the various components that need to be worked on was really integral in me being able to understand what this project truly entails.

The last design task we did at the end of the week was brainstorming all of the possible solutions to our problem. While my team and I already had a clear idea about what the prototype would look like, it was really refreshing to be able to sit down and just come up with ideas even if we knew that a lot of them would not come to fruition. Something that I sometimes find myself struggling with is how narrow-minded I can be when it comes to problem-solving. When I encounter a problem, I get into the habit of putting all of my effort into the solution that comes to me first rather than assessing the situation at hand and taking my time to develop a well-thought-out solution. Forcing myself to come up with multiple alternatives to our mannikin idea helped keep my mind open.

While my team and I made a lot of progress in the design process, several highlights for us were the various workshops that we participated in throughout the week. I had a lot of fun learning how to breadboard circuits and work with 3-D printing software in the design workshops. Even though I don’t see myself heavily utilizing these skills within my actual project, it was great to just be able to sink my feet into territory I have never approached and even apply the physics knowledge that I learned in the classroom. Furthermore, I really enjoyed the professional workshops on engaging in difficult conversations and addressing microaggressions. Effective interpersonal communication is a skill that I have struggled with for quite some time, so it was great just to be able to have the time to walk through how to approach difficult professional situations.

Overall, I am really proud of the progress my team and I have made within and outside the engineering design process. Since we have been focused on researching the problem context and working out the logistics of our project, we haven’t encounter a lot of challenges, but I do anticipate barriers in our progress during week 3 as we start to do our low-fidelity prototype. I am looking forward to updating everyone on my team’s progress in the upcoming week!

 

Take care,

Lam

This week also passed by so quickly as we rapidly went through daily workshops, guiding us through the different stages of the design process. Design criteria, comparison charts, usability, brainstorms, evaluation…all crucial elements behind the scenes that contribute to the eventual fruition of any design. Before this week, I wasn’t fully aware of the mini details that are absolutely important even to such a simple design like a daily water bottle. For any thoughtful design, its components are all purposeful. I specifically enjoyed the brainstorming workshop the most since there was a lot of stimulation for our creativity. Through creating anti-solutions and exploring unconventional usage for a blender, we were able to truly bring ourselves out of the box, getting started on brainstorming for our own project. This week, our team also got the amazing opportunity to interview Global Health 360 Fellows, Abby and Josh, and their Clinical Research Engineer, Sonia. We were able to get many of our questions answered and now have a much greater understanding of the context our solution is intended for. And with that, we were able to start storming our brains for some ideas, based on our background research and exploration of current similar solutions (Here is one of mine). We are so excited to continue on with our brainstorming! 

                                                                 

Another highlight of the week was also the Computer-Aided Design (CAD) workshop. It was my first time working with a 3D design, and we were guided through making this really creepy-cute smiley face keychain. Hopefully we will get to 3D print it out this coming week! 

                                                                     

As always, I would like to show appreciation for the mentors and the leadership team of the internship for guiding us through many helpful and engaging workshops! And I would also like to thank everyone who has followed our journey so far via these blogs. I hope you all are learning something new with us along the way! See you next week 🙂

Hi everyone! My name is Shreya Jindal and I’m so excited to be interning at Rice 360 this summer. I am a rising junior at Hanszen College, and majoring in bioengineering. I am particularly interested in sustainable/longlasting design and committed to bringing this into our project this summer. Last semester, I took a course BIOE 360: Appropriate Design in Global Health, which helped foster my interest in needs finding and design for global communities. I was extremely interested in continuing my growth and understanding of working on projects in these spaces and thought that this internship would be the perfect place to do so.

Our project this summer is designing a 3D printed prosthetic hand for Eric Jr, an extremely high energy six year old with a love for basketball. We plan for our designs to be modified specifically to allow Eric Jr. to play basketball from one of our project head organization e-NABLE’s database of prosthetic models. My teammates, JJ and Alex, and I are super excited to be working on this project for which has a very immediate impact.

Something that I feel like I’ve missed in a lot of my design coursework is direct interaction and collaboration with users from the beginning to the end of the design process. I am so excited to say that within the first week, we’ve already met with and learned so much from Eric Jr. We briefly played basketball with him outside and he showed us his very impressive moves. We finished off the day making a mold of his smaller hand to eventually use to fit and size the prosthetic. Later in the week, we interviewed Arinze, who has a lot of experience working with e-NABLE models. Next week, we plan to do a lot of background research, determine our design criteria, and get started on some solution brainstorming.

Hi all! My name is Rachel Dang, currently a rising sophomore at Martel College double majoring in Biosciences and Economics, with a minor in Global Health Technologies. I received the opportunity to be part of the Rice 360 Internship this summer, working with the SEED internship teams at the OEDK.

 

First week passed by in the blink of an eye. Yet, I have learned so much. 

 

We had orientation and the project fair. I remember being super excited and also somewhat stressed about having to commit to just one out of the seven extremely interesting projects. I have been notoriously indecisive, so that was the first hurdle I had to jump over. After serious consideration, I went with the NEST360 Charging and Sanitisation Station for Low-Resourced Hospitals project. NEST360 was founded with the goal to save babies’ lives, and I highly recommend you all to read more about their wonderful work here (https://nest360.org/impact-report/)! Interestingly enough, I was initially scared of this project due to its many unfamiliar elements. However, the mentor of the project, Ms. Jackie Foss, with her contagious enthusiasm and passion for the project, had convinced me to take on new challenges this summer. 

 

And so, team NESTation was formed (I am the proud mother of this name). Since our team will be the first team to ever take on this project of creating a charging and sanitising station suitable for low-resourced hospitals to efficiently accommodate limiting spaces, we have been so excited and overflowing with ideas. Despite this excitement, wanting to jump into bringing our ideas to life, we know to keep ourselves grounded in first truly understanding the problem via needs finding, the important foundation of the engineering process. 

                                                         

 

Another highlight of the week was definitely the hand tools workshop. I used to be scared of these really loud machines, but now I can tackle them even in a dress! And we got to apply these skills to make cute houses for cute Houston bats! 

                                       

In all, the first week has been an amazing experience, and I am looking forward to having you all to join me on my journey this summer!
