1. Progress Report
Group 2
Yiwei Liu, Jenny MacPherson, Kenneth Fung, Graeme Larsen, Jono Aske

2. Review
Proposal: Device designed to open medication vials and potentially other kinds of bottles
Try and remove the torsion required by the user and only require a push
Original idea was based on the concept of a retractable pen

3. Progress Update
Contacts: Have met with Dr. Carl Adams (Physics) and Steve Macdonald (Machinist)
Design: Our conversations have developed our options for potential designs
Mr. MacDonald introduced us to triple start thread
Looking into other products that we could emulate (Spin-top toy, mojito muddler)

4. Progress Update
Research: We have begun force testing on various types of pill bottles
Dr. Carl Adams set us up with tools from his physics lab
This will help us to figure out which design will be most effective
Going Forward:
Continue our research and look into torsional forces
Figure out which of our designs will be most effective
Come up with initial prototype and meet with Steve Macdonald

5. Experiments

6. Unknowns 3 unknowns: Vertical force required Rotational Force Required
Degree of rotation necessary

7. Vertical Force Test
Bar attached to top of a post via pivot, lies flat across top of pill bottle
Load applied to end without pivot until necessary force is reached
Force on cap calculated using sum of moments about pivot
Force vs. Displacement mapping for cap of pill bottle

9. Rotational Force Test String wrapped around outside of cap
Enough vertical force is applied to disengage locking system
Pull horizontally on string using Newton meter
Force required to break static friction is reading on Newton meter when the cap begins to turn

10. Angle of Rotation Attach pin to top of cap, sticking out horizontally
Place protractor under bottle
Record initial position (º) of pin when cap is locked
Turn cap until open and record new position
Difference in angle (º) is the angle of rotation required

11. Design Challenges Materials Left-handed thread vs. push-pen design
Machinist does not have necessary tools
3D printer not large enough
Left-handed thread vs. push-pen design
Angle of rotation
Ease of use
Ease of build

12. Design Analysis

13. Old Design

14. Updated Design

15. Movement of the Spiral Hand Drill

17. Another Design Option

18. Design Schedule

19. Updated Gantt Chart

20. Activity Chart

21. Visual of Activity Chart

22. Next Steps
After we collect the data from our experiment, we will see if our design meets the requirements.
Meet with the rest of our contacts.
Finalize our design right on schedule and create a final AutoCAD including the dimensions of our prototype.
Schedule another meeting with Steven MacDonald to discuss our finalized design.
Gather materials and start assembling our prototype.
