156B Week 4

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

• • The project's main focus remains the same, emphasizing the need to be hand-powered and ergonomic. The target audience is now medical students and "home-care" professionals in the United States. The team is moving forward with a linear induction power generator.

  • The team had designed a handle, and will be designing new ophthalmoscope and otoscope heads

  • Project team will be testing effect of linear generation (shaking) on lenses

Accomplishments from Previous Week

• • Presented Design proposal, which includes 2-head design, linear induction power generation,use of capacitor

  • CAD handle design for ophthalmoscope

  • Met with sponsor, received design approval

  • Purchased ophthalmoscope and otoscope heads

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

• • CAD ophthalmoscope and otoscope heads

  • 3D print handle design

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

• • Sponsor approves of double headed design

  • Wants entire design to be symmetrical in order to use for both hands

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

• • Good proof of concept experiment 

  • Improve explanation of why batteries are an issue for sponsor

  • Explain characteristics of user, and overall vision for the product

  • Is it possible to make the moving magnet small enough to replace 2 batteries? Fit the design into existing otoscope?

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

• • Test how charging device will affect the lenses of both ophthalmoscope and otoscope heads

  • Redo linear induction power analysis to determine current output from each shake

  • Improve description of project goal and target customer

Risks and Areas of Concern

• • Ruggedness of device, ensure that device that does not break while producing power

  • Ensure that power generation is small enough to fit inside design

Resources or Information Required but not Available

• • Funding/ Index Number

Schedule

• • Describe upcoming milestone

  • Update Gantt chart.

Budget (list amount spent and amount remaining)

• • Budget: $1500

  • Spent: $47.73

  • Total remaining: $1,452.27
