Assignment 8.2/9.2

8.2. Product liability: identify any potential hazards in the proposed design, e.g., changes that may occur during the useful lifetime

9.2. Product liability: provide solutions to eliminate hazards identified in Assignment 8.2, e.g., changes that may occur during the useful lifetime

Fluid degradation:  

a. Hazard: Over time, the fluid may degrade due to oxidation, thermal stress, or contamination.

b. Solution: choose fluids that have high oxidative and thermal stability. 

Other material breakdown: 

a. Hazard:  Materials used to construct the LLM, such as ceramics, metals, and polymers, may begin to crack under long-term mechanical stress, corrode if exposed to certain fluids, or break down under UV exposure.

b. Solution: Begin using composite ceramic-metal hybrids for better toughness where it’s needed.

Electrical damage: 

a. Hazard: Even though immersion cooling prevents air exposure, if the fluid degrades, electrical shorts can still occur. Liability could fall on the fluid manufacturers, hardware designers, or integration engineers if the system weren’t properly rated or tested.

b. Solution: The proper dielectric fluid shall be used, and tests and maintenance should be performed to limit degradation.
