Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If seizure screw connections are used to enable tight connections in small footprint housings, then ease of installation and adaptability to different orientations are improved, but performance at frequencies above 1.2 GHz deteriorates

Engineering Contradiction:
Improveease of installationVSAvoidperformance at high frequencies
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The connector interface is segmented into multiple functional components: a housing, a conductive body with signal path, a dielectric member with bore, and a seizure screw. This segmentation allows each component to be optimized for its specific function while working together to achieve both ease of installation and high-frequency performance. The conductive body can be separately formed and then integrated with the dielectric member, enabling precise control of electrical characteristics.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Different regions of the connector interface are given different properties: the conductive body provides electrical connectivity and signal transmission, the dielectric member provides insulation and mechanical support, and the seizure screw provides mechanical fastening. The dielectric member is positioned specifically to isolate the center conductor from the housing while maintaining signal integrity at high frequencies.

Principle #3Local quality

2Adaptability or versatility

If seizure screw connections are used to connect cables from top, bottom, or side orientations, then adaptability to different orientations is improved, but connection reliability at frequencies above 1.2 GHz deteriorates

Engineering Contradiction:

Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The connector interface is designed as a universal connection mechanism that can accommodate cables from multiple orientations (top, bottom, side) through the same basic structure. The dielectric member with its bore and the conductive body work together to provide reliable electrical connection regardless of cable approach direction, while maintaining high-frequency performance through controlled impedance and proper shielding.
