Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If multiple complementary sheet metal frames are used for shielding, then electromagnetic shielding coverage is improved, but device complexity and manufacturing cost increase
Solution Approach 1:
The shielding is divided into two identical L-shaped shielding elements instead of using multiple complementary sheet metal frames. Each L-shaped element covers a quadrant of the connector, and together they form complete circumferential shielding. This segmentation into identical modular units simplifies manufacturing and assembly while maintaining full shielding coverage.
Solution Approach 2:
The shielding elements are designed to be universal and identical for all four quadrants of the connector. The same L-shaped shielding element design can be used repeatedly across different positions, eliminating the need for multiple different complementary frames. This universality reduces part numbers, simplifies inventory, and lowers manufacturing complexity.

If multiple complementary sheet metal frames are used for shielding, then electromagnetic shielding coverage is improved, but manufacturing cost increases
Solution Approach 1:
The shielding is divided into two identical L-shaped shielding elements instead of using multiple complementary sheet metal frames.

This segmentation into identical modular units simplifies manufacturing and assembly while maintaining full shielding coverage.
Solution Approach 2:
The patent employs identical shielding element designs that can be mass-produced using the same manufacturing processes and materials. This standardization allows for economies of scale in production, reducing per-unit costs compared to custom-complementary frames that would require different manufacturing setups and higher tooling costs.
3Object-affected harmful factors
If outer contact elements are connected to protective conductor for shielding, then electromagnetic shielding is achieved, but data transmission capability deteriorates
Solution Approach 1:
The shielding is divided into two identical L-shaped shielding elements instead of using multiple complementary sheet metal frames. Each L-shaped element covers a quadrant of the connector, and together they form complete circumferential shielding. This segmentation into identical modular units simplifies manufacturing and assembly while maintaining full shielding coverage.
Solution Approach 2:
The L-shaped shielding elements act as intermediary structures that provide electromagnetic shielding without interfering with the contact elements. The shielding elements are positioned around the contact elements rather than using the contact elements themselves for shielding, allowing both data transmission and electromagnetic protection to function simultaneously without conflict.
