Project Objectives
High Priority Objectives
LBNP chamber must maintain negative pressures (~25mmHg) for at least 10 minutes
Device must work in supine position
Device must be self generative
Second Priority Objectives
Provides resistive and aerobic leg exercise
Other Constraints and Issues
Design solutions should revolve around using the current prototype
Leakage must be minimized to maintain negative pressure
Better reinforced chamber to prevent buckling
WOW Design Solution
Ask what would their dream design solution would be like. You may not achieve this, but it is good to know what it would be like.
Risk Reduction Strategy
Characterize the leakage rate from the current prototype and devise options to prevent pressure loss
Compare substitute materials for better chamber reinforcement
Intermediate Milestones
Brian storm ideas and characterize current prototype
Conceptualize design solutions
Risk Reduction analysis on design concepts
Finalize design
Material acquisition
Assembly and Fabrication
Testing
Optimization
