P16081: Systemic Circulation Detailed Design Review Mallory Lennon John Ray Jacob Zaremski Robert Kelley Fabian Perez

Agenda Updates to Customer and Engineering Requirements System Drawings Resistance Pressure Sensors Compliance Tanks LabView Bill of Materials Procurement and Fabrication Test Plans Risks Project Plans Mallory we would like to highlight CR ER based on feedback and a better understanding of our system system drawings subsystems bom preliminary testing plans

Goals Present progress toward final detailed design Identify which areas need more work Receive feedback Create final action plan Mallory

Updates to CR and ER Mallory

Customer Requirements Mallory made some ambiguous descriptions more scecific

Engineering Requirements Mallory broke down pressure into 3 separate req

Engineering Requirements Mallory decided on an ID lifespan

Engineering Requirements Mallory defined spill identified a sme for safety

Compliance Ranges vs Fluid Height Mallory

LabView Fabian

LabView Code (Front Panel) Tab Control Combined or separate pressure waveforms Calculated vs. Theoretical Add more tabs for pressure across resistance Fabian

LabView Code (Block Diagram) Goal: Real-time waveform acquisition Achievable with the DAQ device Fabian

Bill of Materials Jack

Updated Bill of Materials (1 of 3) Jack explain why it’s blank for now and NOT INCLUDED in budget

Updated Bill of Materials (2 of 3) Jack sheet fittings tubing

Updated Bill of Materials (3 of 3) Jack Explain why it’s blank and that there is also the possibility of us making our own out of scrap material and a few bolts/screws, which would be inexpensive

Potential Material Sources Electrical components from other RIT labs Past MSD teams leftover supplies Luer Locks Luer Lock Adapters Zip Tie clips Custom 3D printing fixtures Avoids buying in bulk Control over dimensions Jack

Procurement and Fabrication Jack

Procurement Current Items Purchased: Honeywell Pressure Sensors (2) Protoboard Current Items Owned: 40 feet of 2mm tubing Honeywell Pressure Sensor (2) Jack

Fabrication Machines and Tooling: MACH 2 2020C Water Jet (flowwaterjet.com) 2m x 2m [6.5’ x 6.5’] Overall Dimensions 2D DXF file exported from solidworks Bonding Material (clear, water-thin solvent cement) 1 min. working time, 2 min. fixture time, 24 hr 80% strength set time 3D Printer Cost - first 50 grams free, $0.03/gram after Lead - self-operated machines Material - PLA or ABS Difficult Assembly/Fabrication steps: Sealing the top Drilling holes without spider webbing the material Jake

Priority Fabrication Need to make the Pressure Sensors operable 3D Printed T-Tube Connector 1 in to 1 in to ¼ in Connect the tubing, luer lock stopcock, and the electronics Assemble the compliance tanks Attach all tube fittings, air valve, and pressure bulb Create the external resistor/clamp Jack

Benchmark set-up Jack - talk about DI water and problems with air; we can either invert or we have to include a valve

Preliminary Test Plan Ideas Jack

Test Plans (based on Engineering Requirements) Jack

Pressure Sensor Test Plan Obtain a piece of tubing 12 inches in length Fill with DI water and cap each side Pressure in the tube is 12 inH20 Measure the pressure with the pressure sensor Compare the recorded value vs. the theoretical value Jack

Resistor Test Plan Resistance: TBD pending access to a pump and working pressure sensor. Resistance: Calculating the resistance based on draining a known quantity of water (Calibration curve). A hose clamp can be modeled as a Clamp Valve. http://www.resistoflex.com/clamp_specs.htm Rob http://www.resistoflex.com/clamp_specs.htm

Risks Over Time Jake

Project Plans Rob

Project Plans (Phase 4) Rob

Rob, spelling, can you add ER and CR updates for me?

Project Plan (Phase 5) Rob

Rob: spelling, add full pressure sensor testing and ready to go for next semester

By the end of MSD I Working pressure sensor Find/order all connectors required to test Lab outline Details on how 3-hours will be spent Collaborate with Dr. Bailey Complete testing plans Mallory

Efficiency Update Areas that have improved Improved collaboration with P16080, more cohesiveness required Areas that need improvement Structured meetings Ideas moving forward Individual 3-week plans Mallory

Updates on Outside Presentations/Competitions Abstract has been accepted to ASEE 2016 Annual Conference in New Orleans, LA Paper due by February 1st 2016 Searching for other competitions as well Mallory Thank Dr. Bailey
