Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the electromagnetic generation module is disposed inside the cabinet, then the heating function can be integrated, but the heating space is occupied and heat dissipation is difficult
Solution Approach 1:
The electromagnetic generation module is extracted from the cabinet interior and disposed outside the cabinet. This extraction resolves the space occupation problem while maintaining the heating function through the heating cavity that can receive objects to be heated and transmit electromagnetic waves effectively.
Solution Approach 2:
A heating cavity is introduced as an intermediary structure between the electromagnetic generation module (outside the cabinet) and the objects to be heated. This cavity allows electromagnetic waves to be transmitted to heat objects without requiring the generation module to be physically inside the cabinet, thus preserving heating space.
2Productivity
If the electromagnetic generation module operates at high power, then heating efficiency is improved, but heat dissipation becomes difficult affecting service life
Solution Approach 1:
The heat generated by the electromagnetic generation module during high-power operation is converted from a harmful factor into a manageable parameter. By providing dedicated heat dissipation holes and positioning the module outside the cabinet, the heat is efficiently dissipated to the external environment, preventing overheating and extending service life while maintaining high heating efficiency.
3Temperature
If the electromagnetic generation module is exposed to the external environment, then heat dissipation is improved, but moisture and dust can affect the module
Solution Approach 1:
The cabinet structure acts as a protective shell that selectively isolates the electromagnetic generation module from harmful environmental factors. The heating cavity within the cabinet provides electromagnetic wave transmission capability while the cabinet walls protect against moisture and dust, allowing the module to be positioned outside for heat dissipation without direct exposure to harmful elements.
