Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If an electric heating wire is mounted in a copper tube to directly heat the refrigerant, then the heating efficiency of the refrigerant is improved, but the sealing performance and reliability of the junction deteriorate, and electrical safety problems occur
Solution Approach 1:
The patent introduces an electromagnetic heating assembly as an intermediary device between the power source and the refrigerant. This assembly includes an electromagnetic coil that generates a magnetic field to induce eddy currents in a conductive plate, which then heats the refrigerant indirectly. This mediator approach avoids direct electrical contact with the refrigerant while maintaining efficient heating, thus resolving the contradiction between heating efficiency and electrical safety.
Solution Approach 2:
The patent replaces the mechanical/electrical heating wire system with an electromagnetic field-based heating system. Instead of using resistive heating wires that require physical insertion and electrical contact, the system uses electromagnetic induction to generate heat in a conductive plate that contacts the refrigerant. This substitution eliminates the sealing and electrical safety issues while maintaining heating efficiency.
2Speed
If a heating assembly with complex structure is used to rapidly heat the refrigerant, then the heating speed is improved, but the manufacturing complexity and production cost increase
Solution Approach 1:
The patent divides the heating assembly into distinct functional modules: an electromagnetic coil assembly, a conductive plate, and a support structure. This segmentation allows each component to be manufactured independently using simple processes, then assembled together. The modular design achieves rapid heating through coordinated operation of these simple components without requiring complex integrated structures.
Solution Approach 2:
The patent optimizes heating speed by adjusting parameters such as the number of turns in the electromagnetic coil, the material and thickness of the conductive plate, and the gap between components. By carefully selecting these parameters, the system achieves rapid heating with a relatively simple structure, avoiding the need for complex designs.
3Loss of energy
If the electromagnetic coil disk is positioned close to the heat transfer plate for efficient heat transfer, then the heat transfer effect is improved, but the risk of direct contact and safety issues increases
Solution Approach 1:
The patent uses a conductive plate as an intermediary between the electromagnetic coil and the refrigerant. The electromagnetic coil generates a magnetic field that induces eddy currents in the conductive plate, which then transfers heat to the refrigerant. This intermediary structure ensures that the coil never directly contacts the refrigerant, eliminating electrical safety risks while maintaining efficient heat transfer through optimized positioning and thermal contact of the plate.
