Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If compression refrigeration systems are used for battery cooling, then cooling capability is improved, but installation space requirement increases
Solution Approach 1:
The patent replaces the mechanical compression refrigeration system with a Peltier element-based thermoelectric cooling system. The Peltier element uses electrical current to generate a temperature difference directly, eliminating the need for compressors, refrigerants, and associated mechanical components, thereby significantly reducing installation space while maintaining cooling capability.
Solution Approach 2:
The patent changes the operating parameters by using electrical current as the driving force for cooling instead of mechanical compression. By applying voltage to the Peltier element, the system achieves active cooling through the Peltier effect, where one side becomes cold and the other hot, providing efficient battery temperature control in a compact form.
2Temperature
If compression refrigeration systems are used for battery cooling, then cooling capability is improved, but environmental balance deteriorates
Solution Approach 1:
The patent eliminates the use of compression refrigeration systems that rely on harmful refrigerants by substituting them with solid-state Peltier elements. This substitution removes the source of environmental pollution associated with refrigerant leakage, providing an eco-friendly cooling solution that maintains battery temperature control without compromising environmental balance.
3Temperature
If heating devices and compression refrigeration systems are used for temperature control, then temperature control capability is improved, but device complexity increases
Solution Approach 1:
The patent employs Peltier elements that can function in multiple modes: when current flows in one direction, they provide cooling; when current direction is reversed, they provide heating. This single device replaces the need for separate heating devices and compression refrigeration systems, simplifying the overall system architecture while maintaining comprehensive temperature control capability across different operating conditions.
