Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If the substrate is supported by a non-conductive holder, then the structural support is provided, but the EMI noise cannot be reduced and grounding is insufficient
Solution Approach 1:
The holder is changed from a non-conductive material to an electrically conductive material, fundamentally altering the electrical parameter of the support structure. This enables the holder to serve dual purposes: providing mechanical support and enabling EMI shielding and grounding, thereby resolving the contradiction between structural support and electromagnetic interference reduction.
Solution Approach 2:
The holder is designed to perform multiple functions simultaneously: mechanical support for the substrate, electrical grounding connection, and EMI shielding. By making the holder electrically conductive, it can serve both as a structural element and an electromagnetic interference barrier, eliminating the need for separate grounding components and improving overall system reliability.
2Stability of the object's composition
If the substrate is freely positioned on the frame, then the installation is simple, but the substrate sags toward the frame
Solution Approach 1:
The holder incorporates an elastic leg that can dynamically adjust to accommodate variations in substrate positioning. The elastic deformation capability allows the holder to maintain continuous contact with the substrate and frame while absorbing positional variations, providing stable support without requiring complex adjustment mechanisms or precise pre-positioning.
Solution Approach 2:
The elastic leg changes its physical state through elastic deformation when contacting the frame, transitioning from a rigid support to a flexible contact element. This parameter change enables the holder to adapt to different substrate positions and maintain stable contact, simplifying the overall support structure while ensuring positional stability.
3Strength
If a rigid holder is used to support the substrate, then the structural support is strong, but the holder cannot maintain continuous contact with the frame
Solution Approach 1:
The holder transitions from a completely rigid structure to a semi-rigid structure with elastic components. The elastic leg maintains continuous contact with the frame through elastic deformation, ensuring reliable electrical connection and mechanical support while accommodating minor positional variations. This dynamic capability ensures contact continuity without compromising the overall structural strength.
