Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional male and female connectors with perpendicular terminals are used, then the connector assembly can be manufactured with existing processes, but the signal transmission quality deteriorates in high-speed applications due to architectural limitations
Solution Approach 1:
The connector is divided into separate mating modules, each with its own shielding structure. The metal shield surrounding member is segmented to surround individual mating portions, allowing independent optimization of each module's shielding effectiveness while maintaining overall signal integrity in high-speed applications
Solution Approach 2:
The metal shield surrounding member is nested around the mating portion of the conductive terminal, creating a nested shielding structure. This nested configuration provides effective electromagnetic shielding for the signal transmission path without adding significant external dimensions to the connector assembly
2Ease of manufacture
If conductive terminals with perpendicular mounting portions are used, then the terminals can be mounted on circuit boards using conventional methods, but the terminal structure complexity increases and shielding effectiveness decreases
Solution Approach 1:
Instead of having the mounting portion perpendicular to the mating portion as in traditional connectors, this invention inverts the configuration by having the conductive terminal extend along the mating direction with the mounting portion at the end. This inverted structure simplifies the terminal geometry to a linear form that is easier to manufacture and provides a more effective shielding configuration
Solution Approach 2:
The metal shield surrounding member is specifically configured to surround the mating portion where signal transmission occurs, providing localized shielding quality where it is most needed. The shielding structure is optimized for the specific geometry of the extended conductive terminal rather than using a generic shielding approach
