156A Week 10

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

• • Storming process for the needle insertion device

Accomplishments from Previous Week

• • Communication with the client through email

  • The client provided a patent pending document for further description after signing NDA (non-disclosure agreement).

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

• • Prepare the final presentation (Ryan, Maverick, Peter, Dohwan)

  • Further investigate risks (Ryan, Maverick, Peter, Dohwan)

  • Understand risk reduction methodology (Ryan, Maverick, Peter, Dohwan)

  • Receive feedback from the client regards the risk reduction process (Ryan)

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

• • Initial risk analysis / chosen components look good (3/14, teleconference)

  • Suggested additional design analysis for shape of needle tip (pencil and bevel) (3/14, teleconference)

  • Working on CAD model from scratch on OnShape (3/14, teleconference)

    • learn how to use this web-based CAD program

  • Helicon shape was chosen for better control of insertion (3/14, teleconference)

  • Client has its own prototype for inserting device; however, the client wants us to work on the initial prototyping process (3/14, teleconference)

  • Sponsor was unsure how the billing process works (3/14, teleconference)

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

• • Miscommunication regarding the location of progress reports and required assignments (3/14, class meeting)

  • Concerned about risk analysis regarding rotational skin penetration with understanding parameters: velocity, force, bending moment, and etc (3/14, class meeting)

  • Skeptical with the helicon shape for needle injection process (3/14, class meeting)

  • Utilize Dave for sharing further questions or concerns (3/14, class meeting)

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

• • N/A - cannot share information due to NDA

Risks and Areas of Concern

• • Can we actually conduct energy analysis for rotational insertion

    • Initially, do not worry about rotational part

    • Understand the characteristics of skin for different layers and investigate required force / velocity

    • Dave's suggestion: look into spacecraft control system

  • How much information can we share with the classmates during the risk reduction presentation?

    • Dave: as much as we want to. Even though the students have not made NDA with Capillary Biomedical Inc., the students have submitted student agreement form for this class

Resources or Information Required but not Available
