156B Week 7

Overview of Status of Analysis, Design, Fabrication, Tests, etc.

Accomplishments from Previous Week

● Tested alternative flexible materials to replace the hot glue compared to hot glue (Garrett/Miles)

● Continued designing and producing other prototypes (Jordan/Ho)

● Neoprene sock with inner rubber layer in critical areas (Ho)

● Completed 3D model for test samples for Chris Cassidy (Miles)

Goals for Next Week (list names after each item). Use specific and measurable objectives.

● Create 2 prototypes from new design concepts (Jordan/Ho)

● Testing flexible 3D printed soles once available (All)

● Trying 2 more hot glue replacements for insoles, otherwise optimize hot glue design (Garrett/Miles)

● Field test neoprene/rubber prototype (Jordan)

● Cost estimation (Jordan)

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

● Try to protect the foot as much as possible, make sure to not manufacture any weaknesses

● Hardness testing requires a big machine, not really feasible

● Final step will be testing the finished water sock on the pendulum on different areas

● Pendulum

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

● The materials aren’t hard to come by so manufacturing (on a big scale) could be done in one place

● There could be weak point between the insole and the other parts of the shoe depending on fabrication methods

● In the “existing solutions” part of the report, we should use other puncture resistant materials/products, even if they’re not necessarily footwear or meant to be used in the ocean.

● Try to measure our product using conventional standards, ie. safety standards

Risks and Areas of Concern

● Reducing drag

● Protecting mainly the foot area without compromising wearability

● Comfortability, durability, and longevity of the boot

● Professionalism of final prototype

Budget (list amount spent and amount remaining)

● Plan to buy more zippers, rubber, and neoprene

● Previous amount spent: $305.77

● New amount spent: $305.77

● Total remaining budget: $694.23
