Overview of Status of Analysis, Design, Fabrication, Tests, etc.
Our product is built and we are in the optimization and testing phase.
Multiple components purchased to test different systems.
Substantial progress made
Accomplishments from Previous Week
able to build first prototype and it worked. Set up the controller. Have a working prototype of the app.
Goals for Next Week (list names after each item). Use specific and measurable objectives.
Philip- help with controller. Help Alex build vest. Continue to communicative with outsourcer about what needs to be done.
Alex- keep assembling vest. run tests with both cooling systems.
Carlos- generate a CAD model of the vest so FEA analysis can be done on the system as a whole. Continue working on controller.
Nathan- work on an official logo for our device and upload all the pictures form our slides to our website to show all the stages of our development
Sponsor Comments from Last Meeting and Actions Taken to Address these Comments (indicate date of comments and if via email or in person)
When does Peltier device reach its peak efficiency? (5/8/20)
The Logo can be worried about later when the vest can be more marketable, but focus more on actually making it a reality (5/8/20)
Dr. Suarez will join the presentation meeting on Thursday 5/14/20
Instructor Comments from Last Meeting and Actions Taken to Address these Comments (indicate date of comments and if via email or in person)
Great job at doing a cost benefit analysis for choosing heat sinks. (5/7/20)
Get a list of the price breaks from the supplier if you want to mass produce. (5/7/20)
Make the heating as a feature and the marketing people are good at selling features. (5/7/20)
You have opportunity in the report to say there's more, but first stand on something which is the Dermal Cooling Vest. (5/7/20)
Find a market that can do both cooling and heating. (5/7/20)
When you get a new idea, prove how are you wrong instead of how you are right. (5/7/20)
Comments from Other Students in the Class (indicate date of comments and if via email or in person)
Alex- we can reverse the polarity of the vest so that it heats the user as well as cool the user.
Carlos- we need a soldering iron to build controller.
Philip- we should use the integrated heat sink from cool innovations. Also we need to determine how we want to change our prototype app.
Risks and Areas of Concern
Placement of thermocouple for accurate reading
Optimize size and efficiency of heart sink
Removal of hot air
Learning Swift to connect app to Bluetooth receiver
Values of Kp, Ki and Kd for optimal PID controller
Vapor Lock in the pump
Resources or Information Required but not Available
none for this week
Schedule
The first vest prototype was built with new heat sinks that came in 5/7/20.
Updated Gantt chart.
Budget (list amount spent and amount remaining)
Spent: $341.77
Remaining: ~$3577.72
Progress on Report and Webpage
Home and Final Design pages of web page were updated.
