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

• • Final Design Review 6:00 PM Thursday June 4

    • MAE team created a zoom meeting for this

  • Sponsor prefers nuts and bolts but will accept riveting. They want to avoid welding at all costs

  • They had concerns about if the door is locked mechanically while the surfboard is in.

    • This issue was solved because there is a locking slot in the box to lock the door, not in the frame itself

  • They aren't worried about fabric glue because they want to service the system the little as possible

  • Our team had a few concerns about attaching dampers, but all teams will think on it and get back to each other with solutions

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

• • Concerns about fabric glue reducing the capabilities to maintain the system - recommended we check loctite for suggestions on reapplication

  • Thickness of the metal should be designed for use and abuse, that being said .6in sheets should be fine

  • rho*v^2 - use this to determine the strength of the magnets needed with a surface forewind

  • need to balance the weight with robustness of the system

  • 6061 is a good choice, and start with the ideal thickness while doing tests.

  • Justify whatever number is chosen for the design wind

  • Front page of report- often teams put UCSD logo and Sponsor logos in the top corners and a project photo in the center

  • As long as aluminum is anodized, galvanization shouldn't be an issue

  • The user's manual is supposed to explain how to use it by a consumer or user

  • Fabrication instruction is for assembly and non-standard fabrication instructions

  • Overall, the instructions need to have enough information to recreate the system

  • A table is fine for the BOM in the report

  • Spec sheets can be just links to the online ones for purchased items, and we just create ones for the custom designed pieces

  • Project management needs task distribution and the final Gantt Chart

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
