Overview of Status of Analysis, Design, Fabrication, Tests, etc.
Printed (05/10/16) and assembled (05/11/16) Mk. 5 Prototype filling rack device
Preparing to hand off first working prototype to sponsor
Step 1: Test/practice with Mk. 5 prototype on our own
Step 2: Preliminary test (fill test versus lab tech on Friday 05/13/16 or Monday 05/16/16)
Step 3: Hand off with basic operating procedure
Accomplishments from Previous Week
Renamed the Mk. 5 Prototype Fill Rack to the "WinCF FLUD (Fluid-Loading Utility Device)"
Officially retired "The Mucinator"
Performed further proof of concept testing on Mk. 4 Prototype Fill Rack
Based on sponsor's recommendation, tested range of viscosities from 100% sample medium (thin) to 50% sample medium/50% saliva (thick)
Found that manually tilting device enabled simultaneous filling of sets of capillary tubes with both least viscous and most viscous

Big thanks to Young for the suggestion!
3D printed and assembled Mk. 5 FLUD Prototype
Designed Incubation Chamber
Planning to print ASAP (material: Acrylic, Pojet printer)
3D printed Imaging Rack
Called Stratasys Technical Support to determine sterilizability of ABSplus/TangoBlack & Veroclear materials
Goals for Next Week
3D print incubation box (TEAM 5/12/16)
Test filling against the performance of a lab tech to determine time saved (TEAM 5/13/16 or 5/16/16)
Deliver working prototype to sponsor (TEAM 5/19/16)
Preliminary Design Review Presentation (TEAM 5/19/16)
Sponsor Comments from Last Meeting and Actions Taken to Address these Comments (indicate date of comments and if via email or in person)
(5/5/16) Asked Dr. Quinn about possible range of viscosities to test, told to test 100% sample medium and 50%/50% sample medium/saliva mix
Action - Carried out testing of simultaneous fill of capillary tubes with least and most viscous. Found it was possible with tilting (see video above).
(5/5/16) Informed that we should try to come up with a better name (preferably an acronym) for our filling rack device
Action - Connor came up with the name WinCF FLUD
(5/5/16) Dr. Quinn said our team logo was "strong"
Action - We got to keep our logo on the device
Instructor Comments from Last Meeting and Actions Taken to Address these Comments (indicate date of comments and if via email or in person)
(5/5/16) Gordon/Dave/Young: Suggestions on how to best handle tilting of device (ramp, parking garage spiral ramp, manual tilt by hand)
Action - Tested tilting of device. Found that rapid response & tactile feel of tilting by hand was best
(5/5/16) Gordon/Dave: Discuss possibility of provisional patent with sponsor
Action - Plan to bring up the subject with Dr. Quinn/UCSD technology transfer office
(5/5/16) Gordon/Dave: Filling rack is functional. Be careful not to overhaul design too much. Figure out if mechanisms to handle different viscosities ACTUALLY work
Action - As above, tested filling with different viscosities and found something that worked. Made (hopefully) final design changes, mainly for ergonomics and DFM.
Risks and Areas of Concern
Usability of design - are there any cumbersome aspects of using our device that we overlooked?
Information Required
The sponsor’s/lab technician's thoughts on the current design (will request feedback)
Performance of device against existing procedure (will be answered by test)
Schedule
Refer to schedule outlined under "Goals for Next Week"
Budget
$135 spent, $1865 remaining
Progress on Report and Webpage
2nd Draft of Final Report is due on 05/20/16
