Phase II Prototype and Report 1. Prototype . Develop a fully functioning Phase II prototype by modifying the Phase I prototype or building a new prototype that improves the prototype design and functionality BASED ON USER FEEDBACK (not just what the team members believe needs to be modified). These changes need to be supported and documented by the interactions and surveys from your heavy users. Thus it is CRITICAL for the engineers to be present (but silent) during the heavy user evaluation. 2. Report . Compile the following information into a separate document for Dr. Bush. This document should be no more than 5 pages have a title page with your team name, team number and team members’ names. The report should be single spaced, 12 point font, 1 inch margins and figures should be placed at the end of the 5 pages (photos/figures do not count toward the 5 written pages) . The report should at a MINIMUM contain the following headings (FYI, this is also the grade rubric): Device Section a. provide a sketch (hand sketch is fine) of your initial concept from the innovation tournament b. a photo of your phase I prototype c. provide a 1) technical sketch or CAD drawing – this should include dimensions of your Phase II prototype, 2) a photo of your Phase I prototype, 3) photo of phase II prototype, and 4) text describing your phase II prototype, thoroughly describe the functionality. For example, identify the mechanical components of your prototype and a written discussion on the mechanics, i.e. how it works (linkages, springs, types of mechanical components) and how it moves or performs. How Market Drove Changes Section d. document the significant changes made from Phase I prototype to Phase II prototype and link these changes to your market research. Provide the market data that led to these changes – preferably in a table format with supplemental user quotes in the text that clearly show how these data led you to your decisions. Analysis e. perform an engineering analysis on at least one key component of your design. (You should use statics, strength of materials or dynamics in this analysis). Calculations can be done by hand (preferable.) If any FE analysis is conducted, a hand computation must validate findings . All calculations written out by hand must be legible and in large enough font that all items and variables can be identified. Same with a FBD. All variables must be defined. The calculation page(s) can be in the appendix – but you must discuss them as part of the 5 pages of text. Materials and Manufacturing f. address the type of material that you used to develop your prototype; provide the advantages and disadvantages of using this material. g. provide a discussion as to how you envision that this product would be manufactured if commercialized. Include a discussion of possible materials used (advantage of these materials over your current prototype) – what would be optimal, what would be most cost effective, also Page 8 of 10
what type of forming process would you envision (lay up, stamping, blow molded). You may
