Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If the extension parts at the rear ends of terminals are kept small as in conventional designs, then the connector structure remains compact and simple, but the heat dissipation area is limited and temperature rise cannot be effectively reduced
Solution Approach 1:
The extension parts are bent into three-dimensional stepped plate structures, transforming from simple linear extensions to multi-level spatial configurations. This dimensional transformation increases the heat dissipation surface area without proportionally increasing the overall connector length, effectively resolving the contradiction between compact structure and heat dissipation area.
Solution Approach 2:
The stepped plate structures are arranged in nested configurations where multiple levels of extension parts are stacked and positioned at different heights. This nesting arrangement maximizes the use of vertical space within the connector housing, increasing heat dissipation area while maintaining a compact external dimensions.
2Temperature
If the extension parts are enlarged to increase heat dissipation area, then temperature rise can be reduced, but the connector size and structural complexity increase
Solution Approach 1:
The extension parts are segmented into multiple stepped levels rather than forming a single large flat structure. This segmentation allows the heat dissipation area to be distributed across multiple smaller surfaces at different positions, achieving effective heat dissipation while maintaining structural compactness and reducing overall complexity.
Solution Approach 2:
By bending the extension parts into stepped three-dimensional structures, the design utilizes vertical space and multiple levels rather than simply expanding in a single plane. This dimensional approach increases heat dissipation area without proportionally increasing the connector's footprint or structural complexity.
3Power
If conventional small extension parts are used, then the connector maintains a compact design, but the rated current value cannot be increased due to limited heat dissipation capability
Solution Approach 1:
The stepped plate structures create multiple vertical levels of heat dissipation surfaces, effectively increasing the heat dissipation area within a compact volume. This dimensional transformation enables higher rated current values by providing sufficient heat dissipation capability without requiring a proportional increase in connector size.
Solution Approach 2:
The nested arrangement of stepped extension parts maximizes heat dissipation area within the limited space of the connector housing. This space-efficient configuration enables enhanced power handling capability while maintaining compact dimensions suitable for modern electronic devices.
