OpenVision Unit
OpenVision Shield
Problem: X-Ray emits rays past the extent of unit, potentially being harmful to users, solution must be usable in high-temperature, high-ware environments and must attach to existing units without additional holes
Task: Independently design, source material, and find a manufacturer for shield
Challenges: Communicating ideas with a vendor to get a prototype made, cost restraints, attachment restrictions, must be high durability
Result: Decided to go with a bag that had inserts to block radiation because it was the best way to attach to existing units without new holes, and was the most cost effective and durable due to the flexibility of fabric
Bag Final Design
OpenVision Trigger Handle
Problem: Existing handle hardware catches on inner fillet, does not indicate when the trigger is fully engaged
Task: Independently design, and create prototype of improved handle
Challenges: Can only use off the shelf parts for inner hardware for cost reasons, part is relatively small to fit the hardware needed
Result: Decided to change inner fillets to avoid catching, changed hardware to different off the shelf parts, added a mechanical switch that engages to make a clicking noise when the trigger is fully engaged
Trigger Handle
OpenVision Wireless Solution
Problem: Customers want wireless solution so they can take X-Rays from a far away distance but must attach to existing units without adding holes
Task: Independently design, and create prototype of wireless solution
Challenges: Can only use off the shelf for electronics and cabling to reduce costs, must fit in a compact space, must attach without adding additional holes
Result: Designed 3-D printed box that held off the shelf parts and cables carefully arranged to be as small as possible. Attached by clipping onto external ports on the unit
