Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If a refrigerator with reciprocating mechanical parts is used for cooling, then cooling function is achieved, but large mechanical vibrations are generated
Solution Approach 1:
The refrigerator is extracted from the direct cooling path and placed in a separate heat insulation shell. The cooling function is maintained through thermal conduction via the heat insulation shell, while the vibration source is physically separated from the thermostat, resolving the contradiction between achieving low temperature and avoiding vibrations.
Solution Approach 2:
The heat insulation shell acts as an intermediary between the refrigerator and the thermostat. It transmits the cooling effect through thermal conduction while blocking the transmission of mechanical vibrations, thus mediating between the cooling requirement and the vibration sensitivity of the thermostat.
2Productivity
If the refrigerator is placed close to the thermostat for efficient cooling, then cooling efficiency is improved, but vibration impact on the thermostat increases
Solution Approach 1:
The refrigerator is extracted from the immediate vicinity of the thermostat and placed inside the heat insulation shell. This spatial extraction maintains cooling efficiency through thermal conduction while eliminating direct vibration contact, resolving the contradiction between cooling efficiency and vibration impact.
3Object-affected harmful factors
If vibration isolation measures are added to reduce mechanical vibrations, then vibration attenuation is improved, but device complexity increases
Solution Approach 1:
The heat insulation shell simultaneously serves multiple functions: it provides thermal insulation for efficient cooling, acts as a vibration isolation barrier, and houses the refrigerator components. By merging these functions into a single structure, vibration attenuation is achieved without proportionally increasing device complexity.
Solution Approach 2:
The heat insulation shell is designed as a multi-functional component that provides both thermal insulation and vibration isolation. This universal design allows the same structure to address multiple problems (cooling efficiency and vibration attenuation) without requiring separate dedicated components, thus avoiding excessive complexity.
