Overview of Status of Analysis, Design, Fabrication, Tests, etc.
Redesigned sticker dispenser
Performed proof of concept of bullnose and sticker unrolling with different angles
Started to test loading/unloading method for spool
Designed spool with sticker and carrier spool using hubs and aluminum cylinder
Accomplishments from Previous Week
Confirmed that using a Steel rule die requires too much force
Designed loading/unloading method for spool
Design and calculated gears and handles system considering human factors
Goals for Next Week (list names after each item). Use specific and measurable objectives.
Finalize and test friction break system (Chris and Shancheng)
Have the full prototype and CAD almost ready (Aliya and Ngoc)
Start concretizing sticker receiving platform (Chris and Shancheng)
Sponsor Comments from Last Meeting and Actions Taken to Address these Comments (indicate date of comments and if via email or in person)
Thumbs up on design (04/25 in person)
No need to meet in person until have physical prototype to test with doctors 05/20 (04/25 in person)
Instructor Comments from Last Meeting and Actions Taken to Address these Comments (indicate date of comments and if via email or in person)
Are we creating a constraint that is not necessary by implementing an electrical feedback system? (04/25 in person) Action: Making the full system mechanical with a handle that the doctor will turn.
Take a look at standardized hubs for the spool (04/25 in person) Action: hubs will be used, similar to the ones used for paper towels. Also addresses the problem of easy loading/unloading
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
Making sure that the circumference described by the handle is acceptable for the user to turn comfortably
Fully mechanical vs Mechatronics
Making the mechanism dispense a sticker successfully every single time
Making an effective friction break
Resources or Information Required but not Available
N/A
Schedule
Finalize design (Spool, friction break, bullnose)
Force Torque Adjustments
Build Prototype
Troubleshooting and iteration
Test and feedback with doctors
Budget (list amount spent and amount remaining)
Spent: $652.7
Remaining: $2347.3
Progress on Report and Webpage
Completed all sections due up until Week 4
Working on deliverables for week 5 to have more than 50 % in all sections
Design has changed again so Webpage needs to be updated accordingly
