DESIGN REVIEW Overview
DESIGN OVERVIEW Prototype V2 Prototype V3 Make to Innovate (M:2:I) Spring 2019
PROTOTYPE V2 • Two switches engage/disengage the pawl • Springs provide the tension to create the moment to hold the switch in locked/ unlocked position • If one switch fails, the other can still lock the mechanism Make to Innovate (M:2:I) Spring 2019
PROTOTYPE V3 • One switch to engage/disengage the pawl • Constant force spring on the other side of the double gear • If the one fails the other is able to keep the clamps shut Make to Innovate (M:2:I) Spring 2019
DESIGN REVIEW Constraints
DESIGN CONSTRAINTS • With Micro- g’s budget, the EVA camera Micro-g NExT Requirements mount will be manufactured from The device shall attach to at least two of three interfaces 1 cheaper test-ready materials 2 The device shall include a 1-fault tolerant attach method 3 The device shall use only manual power • To be consider for flight, the camera The device shall allow for camera pitch and yaw mount was designed to fit all three adjustability of ± 45˚ 4 interfaces The device shall be able to pack within 12" x 16" x 18" 5 6 The total must be less than 15 lbs. 7 Device shall be made from NBL approved materials 8 Device shall allow a GoPro to mount to it 9 Pinch points should be minimized Make to Innovate (M:2:I) Spring 2019
DESIGN REVIEW Current Design
CURRENT DESIGN • Decided to continue with prototype V2 due to constant spring causing issues • Reduces pinch hazard caused by constant spring • Simpler to assemble Make to Innovate (M:2:I) Spring 2019
CURRENT DESIGN • Current design uses a double gear • Larger gear moves both sliding arms the same length and in the same direction • Pawl engages smaller gear to lock the sliding arms from opening while attached Make to Innovate (M:2:I) Spring 2019
DESIGN REVIEW Proposed Changes
PROPOSED CHANGES • Removed away from pin design • Added switch system instead of traditional ratcheting system • Removed end of the sliding arm to ease manufacturing/assembly Make to Innovate (M:2:I) Spring 2019
DESIGN REVIEW Design Risks
DESIGN RISKS • Risk 1: Missing NASA deadlines for Micro-g NExT • Mitigation 1: The Micro-g timeline has been advanced • Risk 2: Key component failing during testing at the NBL • Mitigation 2: Conduct comprehensive testing and analysis prior to May • Risk 3: Design flaw resulting in failure to meet requirements • Mitigation 3: 3D print and test prototype version prior to final build Make to Innovate (M:2:I) Spring 2019
