Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If notches are formed in the shielding housing to receive the shielding sheet, then the grounding area is increased, but the contact wall of the notch deforms and warps causing poor contact
Solution Approach 1:
The shielding housing is divided into a main body and a separate grounding connection member. The grounding connection member is specifically designed to provide stable contact with the shielding sheet through interference fit, while the main body maintains its structural integrity. This segmentation allows the grounding function to be optimized independently without compromising the overall structure.
Solution Approach 2:
The grounding connection member acts as an intermediary component between the shielding housing and the shielding sheet. It provides a dedicated interface for electrical connection through interference fit, ensuring reliable grounding contact without requiring notches in the main housing structure. This intermediary element solves the deformation problem by concentrating the contact function in a separate, optimized component.
2Strength
If the shielding sheet is interference-fitted into notches of the shielding housing, then electrical connection is implemented, but the contact wall deforms making the connection unstable
Solution Approach 1:
The grounding connection member is designed as a separate component with specific geometric features (such as protrusions or slots) that enable interference fit with the shielding sheet. This segmentation allows the connection function to be optimized in a dedicated component rather than compromising the main housing structure.
Solution Approach 2:
The grounding connection member is designed with localized geometric features (protrusions, slots, or specific cross-sectional shapes) that provide the necessary interference fit for strong electrical connection. This local optimization of geometry ensures strong connection where needed while maintaining overall structural stability of the housing.
