Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a one-piece shielding structure is used in straight connectors, then manufacturing is simple, but it cannot be effectively applied to right-angle connectors with high-frequency signal requirements
Solution Approach 1:
The shielding is divided into multiple separate elements (first shielding element, second shielding element, third shielding element) that can be independently manufactured and then assembled. This segmentation allows each element to be optimized for specific functions while maintaining overall shielding effectiveness for high-frequency signals in right-angle connector geometry.
Solution Approach 2:
The shielding elements are designed to nest within each other, with the first shielding element having a first opening, the second shielding element having a second opening, and the third shielding element having a third opening that receives the second shielding element. This nested configuration enables effective electromagnetic shielding while accommodating the right-angle connector structure.

This nested configuration enables effective electromagnetic shielding while accommodating the right-angle connector structure.
Solution Approach 2:
The shielding elements are pre-configured with specific openings and receiving structures that enable straightforward assembly. The first shielding element is prepared with a first opening, the second with a second opening, and the third with a third opening designed to receive the second element, allowing for efficient assembly without complex alignment procedures.
