Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If screw fastening is used to fix the shield bracket to an object, then the fixing strength is improved, but the ease of operation and assembly time are worsened
Solution Approach 1:
The fixing member is divided into a clamp portion for clamping the shield bracket body and a fixing portion for fixing to the object. This segmentation allows the clamp portion to provide strong mechanical fastening while the fixing portion enables easy attachment and detachment, resolving the contradiction between fixing strength and ease of assembly.
Solution Approach 2:
The clamp portion is designed to be movable along the shield bracket body and can be locked at different positions. This dynamic design allows for easy adjustment and assembly while maintaining strong fixing strength when locked, thus resolving the contradiction between ease of operation and fixing strength.
2Device complexity
If a conventional shield bracket configuration is used, then the structural simplicity is maintained, but the reliability of electrical connection and grounding is worsened
Solution Approach 1:
The fixing member integrates both mechanical fixing functions and electrical connection functions into a single component. The clamp portion provides mechanical fastening while the conductive portion establishes electrical connection and grounding, merging multiple functions without significantly increasing structural complexity and thereby resolving the contradiction between simplicity and reliability.
Solution Approach 2:
The fixing member serves multiple functions: it clamps the shield bracket body, fixes it to the object, and provides electrical connection and grounding. This multi-functionality ensures reliable electrical connection while maintaining relatively simple structure, resolving the contradiction between device complexity and reliability.
3Ease of operation
If the shield bracket is designed with attachable fixing member, then the ease of operation and assembly time are improved, but the fixing strength may be worsened
Solution Approach 1:
The clamp portion is pre-configured with a clamping structure that can be easily engaged with the shield bracket body. This preliminary configuration allows for quick attachment and detachment operations while ensuring that when properly engaged, the clamping force provides sufficient fixing strength, resolving the contradiction between ease of operation and fixing strength.
