Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If clips are used to clip the carrier element onto the contact element, then the carrier element can be attached to the contact element, but the design requires adaptation to the geometry of the contact element and limits assembly flexibility
Solution Approach 1:
A spring element is introduced as an intermediary component between the carrier element and the contact element. The spring element enables thermal coupling while accommodating different contact element geometries, thus maintaining attachment reliability without requiring adaptation to specific geometries.
Solution Approach 2:
The spring element allows for parameter changes in terms of flexibility and adaptability. By using a弹性 component, the system can adjust to different contact element geometries and assembly positions, transforming a rigid attachment system into a flexible one that maintains reliable thermal coupling across various configurations.
2Adaptability or versatility
If the carrier element is positioned tangentially to the cylindrical contact element, then assembly flexibility is improved, but thermal coupling efficiency may be reduced
Solution Approach 1:
The spring element is designed to concentrate thermal coupling at specific local points where it contacts the carrier element and transmits heat to the contact element. This localized thermal coupling ensures efficient heat transfer even when the overall carrier element position is tangential and flexible.
Solution Approach 2:
The spring element acts as a thermal intermediary that bridges the gap between the tangentially positioned carrier element and the cylindrical contact element. It maintains thermal coupling efficiency by providing direct thermal pathways while allowing the carrier element to be positioned flexibly in a tangential orientation.
