Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the power supply part is installed below the charging part to save space, then the device structure is compact, but heat generated in the power supply part is transferred to the charging part causing overheating
Solution Approach 1:
The device is divided into separate installation spaces: the power supply part is located in a first installation space while the charging part is in a second installation space. This spatial segmentation prevents heat transfer between the two components by physically separating them into distinct thermal zones within the frame structure.
Solution Approach 2:
A frame passage is introduced as an intermediary space between the power supply part and charging part. This passage allows cooling air to flow between the components, acting as a thermal buffer that prevents direct heat transfer while maintaining compact device structure. The frame passage serves as a mediator that enables thermal management in the confined space.
2Power
If the capacity of the power supply part is increased to meet high-current specifications, then the power supply capability is improved, but the size and calorific value of the power supply part increase
Solution Approach 1:
The power supply part is extracted from the conventional location below the charging part and relocated to a separate first installation space. This extraction removes the heat source from proximity to the charging part, allowing the power supply part to be sized for high-current specifications without compromising the thermal environment of the charging part.
Solution Approach 2:
The frame passage serves as a cooling intermediary that allows cool air to reach the power supply part and warm air to be discharged. This intermediary cooling path enables the power supply part to operate at high capacity with increased calorific value while maintaining overall system thermal balance through controlled air flow.
3Device complexity
If the power supply part and charging part are located in the same space, then the device structure is simple, but air conditioning efficiency is reduced due to heat transfer
Solution Approach 1:
The internal space is segmented into distinct installation spaces for the power supply part and charging part, with a frame passage separating them. This segmentation creates independent thermal zones that can be cooled separately, improving air conditioning efficiency while adding minimal structural complexity through the use of partition walls and flow holes.
Solution Approach 2:
The frame passage acts as a cooling intermediary that facilitates efficient air flow between the power supply part and the external cooling system. By introducing this intermediary cooling path with controlled air intake and discharge, the system achieves improved air conditioning efficiency without requiring completely separate device housings.
