156B Week 1
Overview of Status of Analysis, Design, Fabrication, Tests, etc.
Obtained more clear understanding of the project directly from Sponsor
Risk Reduction device completed and tested
Sponsor would like us to make headway in design aspects and creating an electronic controller
Accomplishments from Previous Week
Analyzed data from experiments in regards to coupling effect
Doesn't seem to affect the rest of the system (i.e. close valve 2, only valve 2 pressure drop increases)
Goals for Next Week (list names after each item). Use specific and measurable objectives.
Analyze channel connectors by CFD or Extended Bernoulli to determine best connection for minimal pressure losses
Configure optimal latching/clamping method, redesign layout for 10 channel device to accommodate latching solution
Learn how to link pressure sensors and LCD screen to get a digital readout (and begin implementing on breadboard)
Sponsor Comments from Last Meeting and Actions Taken to Address these Comments (indicate date of comments and if via email or in person)
All comments via Zoom
Would like to see all presentations before presenting
Should explain the pump more precisely
Recommends structure of: Introduce the problem; design parameters; and proceed
Taken under consideration when making our Problem Redefinition PPT
Clearly outlined design requirements
Failure analysis and electrical control
Simplicity and reliability above all else
Will need to keep these in mind when designing our system, choosing valves, and latching mechanism
Weekly meetings should have a section dedicated to clear separation of duties along with normal updates
Scheduled meetings via Zoom
Instructor Comments from Last Meeting and Actions Taken to Address these Comments (indicate date of comments and if via email or in person)
All comments via Zoom
List all parts that need to be done and ID the high risk areas
Anticipate and ID problems
Listed everything out, focusing on flow constriction instead of valves (highest risk) to get the 3-7 mm Hg pressure drop
Should experiment with different types of valves
Might want to consider making our own controlled valve
Designing method to constrict tubing in lieu of valves because the pressure drop in valves is too high
Comments from Other Students in the Class (indicate date of comments and if via email or in person)
n/a
Risks and Areas of Concern
Designing simple latching mechanism that is reliable might be difficult
Constricting flow in another manner to reduce huge pressure losses from valves
Resources or Information Required but not Available
n/a
Schedule
Need to design and test tube constriction method
Need to design final device to incorporate enhanced latching mechanism
Budget (list amount spent and amount remaining)
$0 spent, $227.42 remaining
Progress on Report and Webpage
Updated internal page, uploading Individual Component Analyses
