Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a double-layer shielding structure with direct metal connection is used, then shielding effectiveness is improved, but metal debris interference occurs
Solution Approach 1:
The patent introduces a conductive plastic as an intermediary material between the metal shielding structure and the grounding terminal. This conductive plastic layer prevents direct contact between metal components, thereby eliminating metal debris generation while maintaining the shielding effectiveness through its conductive properties
2Object-affected harmful factors
If linear rectangular blocks are extended in length direction for enhanced shielding, then shielding effect is improved, but structural stability of U-shaped plastic body deteriorates
Solution Approach 1:
The patent transitions from linear rectangular block shielding to a planar sheet-like conductive plastic shielding structure. This dimensional change allows the shielding to cover broader areas without requiring excessive length extension, thereby maintaining structural stability while achieving comprehensive shielding coverage
3Object-affected harmful factors
If conductive plastic is formed integrally with U-shaped plastic body by secondary injection molding, then shielding structure is achieved, but manufacturing complexity increases
Solution Approach 1:
The patent merges the formation of the conductive plastic shielding structure with the U-shaped plastic body into a single secondary injection molding process. This integration eliminates the need for separate assembly steps, reducing manufacturing complexity while achieving the desired shielding structure
