Sponsor Comments from Last Meeting and Actions Taken to A

ddress these Comments (indicate date of comments and if via email or in person)

• • Want us to continue testing for safety to make sure hair and clothing doesn't easily get caught in the folding system

  • While they think that a damping force the full way through the folding is better, they defer to our judgement

  • They want us to focus on having a working, fully fledged prototype, that is the primary goal

    • Proof of Concept is most important. In long term they feel confident they can find solutions later once they know it will work properly

    • They just want a fast, easy system they can test quickly to determine if its even something they want to implement via consumer testing

  • We asked if they would approve our purchase for springs to continue working on the secondary damping system path with the springs attached to the hinges. They would rather we only test the dampers and if we find it isn't adequate but don't have time to do studies on the springs they don't feel that they will be missing information

Instructor Comments from Last Meeting and Actions Taken to Address these Comments  (indicate date of comments and if via email or in person)

• • Aniodization comes in two versions; standard and hard. Hard doesn't work on all alloys so it is important to be aware of the alloy before choosing this. However, Standard is a good overall covering and may well work for what we need

  • Putting a longer shaft in to allow the springs to be attached will require less effort in the long run, if we can find the space

Comments from Other Students in the Class (indicate date of comments and if via email or in person)

• • N/A

Risks and Areas of Concern

• • Due to COVID related concerns, some team members may not be able to participate in prototype testing

  • Designing door so that SurfUp's original RFID lock can fit on it/ attach to it

  • We need to test if the cabinet dampers will be corrosion resistant enough 

Resources or Information Required but not Available

• • Nothing at the Time
