Overview of Status of Analysis, Design, Fabrication, Tests, etc.
Starting 2nd full scale prototype
Implemented spring hinges and piano hinges
Upgraded foam core to plywood board
Testing folding potential (interaction between hinges and screws)
Completed static analysis with FEA
Stress and strain relationship on top and bottom plate
Top plate is extended to support entire locker as it unfolds
Bottom plate caries the majority of load
Working model analysis
Approximate damping solutions and impact in 2D
Accomplishments from Previous Week
Researched options handles (for lifting locker box up and down) (Natalie)
Completed working model analysis (Natalie)
Wrote Application Standards section of report (Natalie)
Completed static analysis in solidworks (Annamarie)
Updated Solidworks model (Adri)
Formatted and moved report to LateX (Adri)
Bought and picked up plywood and screws (Adri)
Bought and picked up foam core (Kevin)
Started 2nd prototype with hinges and plywood (Kevin & Adri)
Handled orders & budget (Kevin)
Confirmed with sponsor about locking logistic and final deliverables (1RFID & Mechanical lock is the major goal) (Team)
Goals for Next Week (list names after each item). Use specific and measurable objectives.

Finish 2nd prototype building
Research on brackets for door
Choose a mechanical lock to best fit our design
Attaching fabric and completing drop test on prototype
Sponsor Comments from Last Meeting and Actions Taken to Address these Comments (indicate date of comments and if via email or in person)
Discussed the locking system again
While the single lock - 2 RFID system is the preferred course, due to time constraints on producing a working prototype they would like a mechanical alternative
The scope of project has thus been redefined to be:
A full design with suggested bill of materials for a final prototype
Design notations with what a RFID locking system would look like and need
Design notations with what a mechanical locking system would look like and need
A bonus objective has been added RE the lock sensor
Currently they use an inductive proximity sensor to determine if the door is locked or not. This draws constant power
Would like a solution that is
Low cost
Difficult to fool by a consumer
Uses no energy to check the lock status
Is directly incorporated into the overall door lock
This objective is secondary to the main scope stated above and should only be looked into and completed if the main scope is achieved ahead of schedule
A note about the budget
We will continue requesting confirmation prior to purchasing items
However, reimbursement will come in a lump-sum at the end of the quarter
The team will be saving receipts and accurate documentation of the amount spent between now and the end of the quarter to ensure this stays accurate
Instructor Comments from Last Meeting and Actions Taken to Address these Comments (indicate date of comments and if via email or in person)
Instructor: Potentially replace magnets with magnetic stainless steel (4/22)
Action: Compared Pros and Cons between magnets and magnetic stainless steel
Risks and Areas of Concern
The original lock (designed by sponsor) is not robust enough to be used by locker
The lock should interact with locker (door) instead of the surfboard station
The locker door can potentially swing around due to windy environment. Can implement dampers stabilize the door
Resources or Information Required but not Available
Schedule
We are on schedule and in accordance with our Gantt chart Budget (list amount spent and amount remaining)
