Concisely list and prioritize the project objectives and constraints
High Priority Objectives
Research and prototype:
‘uncuttable wire hook’
‘Unbreakable outer shell by hammer or screwdriver’
Ergonomic, scratch proof design of outer shell
Second Priority Objectives
Attractive industrial design and optimization by applying DFM principles
Water-, sand- and dust-proofing lock box
Researching locking mechanisms (number, other combinations, dial, button etc.)
*Still same objective as before, but ensure all of the specification of the final model are complete and ready for production.
First tasks (high risks aspects)
Since the device is a complex one, at least two weeks are required to set up a useful hardware test. Hence, the group plans to:
Develop a working model of the lock box on Autodesk Fusion or Solidworks using the specifications of the sponsor, use RFID proof materials for the models
Conduct a FEA simulation of fracture and tensile stress on the lock box to improve strength and reduce breakability
Based on FEA simulation, place purchase orders/sample requests to vendors for lock box materials
Run generative design tests with constraints obtained from sponsor and insights from first FEA tests
Risk reduction tests
Preliminary hardware test: Not viable
Analytical modeling: RFID, Using Autodesk Fusion or Solidworks
Software simulation: FEA test and subsequently, generative design
(tentative)
S/ Week 1
Present new designs to sponsors, and begin to eliminate design concepts.
S/ Week 2, 3, 4
Finalize on one design concept, and reach out to potential vendors for best direction moving forward.
S/ Week 5, 6
Safety testing, performance testing, compiling results, cost analysis
S/ Week 7, 8
build the first iteration of the lockbox, potentially?
S/ Week 9, 10
Further optimization, tweaks in design, addressing future iterations
Future of Tebra presentation ready and presented to sponsors
