156B Week 5

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

• • Linear slider design had been built

  • Tests show the linear slider need improvement

  • Solutions to jamming and size issues have been planned

  • Scissor jack design is back in consideration if other solutions aren't plausible

Accomplishments from Previous Week

• • Built linear slider prototype

  • Tested linear slider prototype

  • Began planning possible solutions for problems with prototype

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

• • Decide on what design to pursue given current slider issues - Team

  • Build updated prototype - Travis and CJ

  • Design safety mechanism for prototype - Justin and Stephanie

  • Complete first draft of report - Team

  • Complete first draft of website - Team

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

• • Our sponsor was unable to meet with us this past week.

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

• • Notes from meeting with Dr. Delson on 04/24/2012

    • Have a prototype built and ready to demo for the next meeting

    • Linear motion is not undesirable but linear sliders may not be good

    • Make sure we completely understand the linear slider problem from MAE 3

    • Look into the possibility of selling two clamps together so that replacing the IV bag would not have to be done on the pole

    • Report:

      • Add figures and numerical values to the background section

      •  Have an actual upper limit for pressure

      • Give the range of times in which we would like the device to operate

      • Explain why we would like to speed up the time - is there a medical benefit or is it purely for convenience?

      • Clearly distinguish between low flow rate and pressurized IVs

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

• • A couple of other students have proposed attaching the device to a hospital bed instead of an IV pole. The team has been discussing this and will talk to our sponsor about it.

Risks and Areas of Concern

• • Areas of Concern:

    • Determining the best course of action for the next prototype

    • Finding a good way to determine the best safety mechanism for our design 

Resources or Information Required but not Available

• • None

Schedule

• • Decide on what design to pursue given current slider issues - May 1st

  • Complete first draft of report - May 4th

  • Complete first draft of website - May 4th

  • Build updated prototype - May 8th

  • Design safety mechanism for prototype - May 8th

Budget (list amount spent and amount remaining)

• • Spent: $175

  • Remaining: $2325

Progress on Report and Webpage

• • Background, problem definition, obejctive and societal impact have been drafted.

  • Remaining sections will be drafted this week.

  • Reports and Internal are up to date but the other sections are still in progress.
