Team Vision for System-Level Design Phase

Team goals for Phase 2 - System-Level design were to:

• Create visuals for Function Decomposition to identify characteristics and components of the heat switch.
• Create a Transformation Diagram to identify the proper functions that need to be performed or are performed by the heat switch.
• Research other alternatives to replace components of the preexisting lab prototype.
• Create a Morphological Table to determine other possible combinations for concept selection.
• Brainstorm solutions for on how to determine the feasibility of certain concepts and current characteristics of the prototype.
• Benchmark current solenoid against other solenoids as well as motors and actuators.
• Benchmark current ratchet design against other designs to increase efficiency.
• Review NASA standards that need to be met by the heat switch.
• Discuss performing a bench mark test on the current solenoid at cryogenic temperatures.
• Update Risk Assessment with new found concerns with the design and applications of the project.
• Send customer Pre-Read and Presentation and change based on his feedback.

Plans for next phase

Our team goals for the next phase is:

• Test current prototype in cryostat to verify mechanical performance
• Begin preliminary detailed design of mechanical subsystems
• Build and test electronics board to verify performance of programmable load
