Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If conventional cooling racks with evaporator, compressor, condenser, and expansion valve are used, then cooling capability is provided, but device complexity increases and energy consumption increases
Solution Approach 1:
The patent replaces the mechanical refrigeration system (compressor, condenser, expansion valve) with a thermoelectric cooling system. The thermoelectric module directly converts electrical energy to cooling effect through the Peltier effect, eliminating mechanical components and simplifying the overall structure while maintaining cooling capability for the server.
Solution Approach 2:
The patent extracts and removes the complex mechanical refrigeration components (compressor, condenser, expansion valve) from the cooling rack, retaining only the essential cooling function through a simplified thermoelectric module. This extraction reduces device complexity while preserving the core cooling capability.
2Temperature
If conventional cooling racks with indoor unit and outdoor unit are used, then cooling capability is provided, but the rack becomes bulky and occupies excessive space
Solution Approach 1:
The patent merges the cooling function directly into the server rack structure by integrating the thermoelectric module within the rack housing. This eliminates the need for separate indoor and outdoor units, consolidating all cooling components into a single compact unit that fits within standard rack spaces.
Solution Approach 2:
The thermoelectric cooling module is nested within the rack structure, utilizing the available space inside the rack housing. The cooling components are integrated into the rack's internal architecture rather than requiring external space, thereby reducing overall volume while maintaining cooling effectiveness.
3Temperature
If conventional cooling racks are used, then cooling capability is provided, but energy consumption increases
Solution Approach 1:
The patent replaces the energy-intensive mechanical refrigeration cycle with a direct electrical cooling solution. The thermoelectric module converts electrical energy directly to cooling effect without the energy losses associated with compression, condensation, and expansion processes, thereby reducing overall energy consumption while maintaining cooling capability.
