156B Week 2
Overview of Status of Analysis, Design, Fabrication, Tests, etc.
Scrapped needle valves, designing our own that will compress tube to restrict the flow
Individual component analysis of tubing completed
Awaiting Sponsor approval to purchase materials to begin fabrication of valves
Accomplishments from Previous Week
Settled on channel connectors
Using only tubing with a valve constriction instead of traditional valve
Drafted preliminary designs for valve that were run by sponsor and have begun modeling for fabrication so we can begin immediately after receiving approval
Latching method will likely incorporate a hinged design and rotated channel patterning to increase clamping force and reduce latches needed
Goals for Next Week (list names after each item). Use specific and measurable objectives.
Finalize model for constriction valve, fabricate and begin testing
Place order for additional sensors, tubing, and motors once receiving approval
Individual component analysis of different filament types for the constriction valve body (glass transition temp of materials)
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 meeting on 4/8
Recommends using the threaded ram valve design
Began modeling for fabrication
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, will be updated after meeting on 4/10
Should consider other valves or make our own
Designing constriction valve to implement into device
Should make the electronics more robust (less "home-grown"-esque)
Find a PCB manufacturer after circuit is finalized based on breadboard testing and solder all components
Wiring harness to connect electronics box with device (link into incubator)
Consider an Arduino shield PCB?
Comments from Other Students in the Class (indicate date of comments and if via email or in person)

Risks and Areas of Concern
Shipping times may delay testing and implementation
Risk Reduction device may not be
Resources or Information Required but not Available
Identify a machine shop/fabricator that will be able to fabricate final device
Use Canvas resource, reach out to possible contacts at Maketory
Schedule
Fabricate and test constriction valve
Successfully implement sensors in conjunction with LCD readout
