Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If voltage generator and other high-temperature components are integrated with cryogenic memory components, then device complexity is reduced, but heat transfer to the memory increases causing malfunctions and increased power consumption
Solution Approach 1:
The patent divides the memory system into distinct temperature zones: a first temperature zone containing the voltage generator and cooler, and a second temperature zone containing the cryogenic memory. This segmentation isolates heat-generating components from temperature-sensitive components, preventing heat transfer that would cause malfunctions while maintaining overall system integration.
Solution Approach 2:
The patent introduces a partition structure as an intermediary between the first and second temperature zones. This partition acts as a thermal barrier that blocks heat transfer from the voltage generator and cooler to the cryogenic memory, while still allowing electrical connections and signal transmission between zones.
2Use of energy by moving object
If cryogenic temperature state is not maintained, then power consumption decreases, but memory malfunction occurs due to temperature rise
Solution Approach 1:
The patent implements a temperature monitoring system that continuously detects the temperature in the second temperature zone and automatically activates the cooler when the temperature exceeds a threshold. This self-service mechanism maintains cryogenic temperatures without requiring constant external intervention, ensuring memory reliability while minimizing unnecessary power consumption.
3Device complexity
If heat transfer from high-temperature region to low-temperature region is not blocked, then device complexity is reduced, but power consumption increases due to cooling requirements
Solution Approach 1:
The patent segments the system into thermal zones separated by a partition that blocks heat transfer. This segmentation prevents waste heat from the voltage generator and cooler from reaching the cryogenic memory, reducing the cooling power required to maintain low temperatures while keeping the system integrated.
Solution Approach 2:
The partition structure serves as a thermal intermediary that blocks heat flow between temperature zones. This intermediary reduces the energy loss to the cryogenic environment by preventing conductive and radiative heat transfer from warm to cold regions.
