Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the power supply module is disposed inside the cabinet, then the device structure is compact, but the heating space is reduced and the power supply module is prone to overheating
Solution Approach 1:
The power supply module is extracted from the cabinet interior and disposed in the space above the cabinet. This separation removes the heat-generating component from the heated space, preventing overheating of the power supply module while maximizing the available heating space within the cabinet.
2Volume of moving object
If the power supply module is disposed outside the cabinet, then the heating space is increased, but the heat dissipation distance is extended
Solution Approach 1:
A heat dissipation fan is introduced as an intermediary device to facilitate heat transfer from the power supply module to the external environment. The fan actively drives airflow through heat dissipation holes, ensuring efficient heat removal despite the increased distance between the power supply module and the cabinet interior.
3Device complexity
If the power supply module is disposed inside the cabinet, then the structure is simple, but the power supply module is affected by damp and dust
Solution Approach 1:
The power supply module is extracted from the humid and dusty environment inside the cabinet and relocated to the space above the cabinet. This physical separation protects the power supply module from moisture and dust contamination, improving its reliability and longevity.
Solution Approach 2:
The power supply box serves as a protective enclosure with heat dissipation holes that allow airflow while shielding the power supply module from direct exposure to damp and dust. The box structure provides environmental protection while maintaining thermal management functionality.
4Loss of time
If heating device is used to heat food, then the heating time is long, but the energy consumption is low
Solution Approach 1:
The electromagnetic heating device replaces conventional thermal conduction heating methods. By utilizing electromagnetic fields to directly heat the food, the system achieves rapid and uniform heating without the prolonged heating times associated with traditional heating elements, while maintaining efficient energy utilization.
