Solution Overview

Problem

Existing relay connectors for coaxial connectors on circuit boards suffer from unstable posture of the GND block, leading to variable electrical connections and performance during high-frequency signal evaluation.

Innovation Solution

A relay connector design that includes a conductive first block with a guide pin, a conductive second block with a board rest part and guide hole, an operating member with a through hole, and a coupling member forming an L-shape, which stabilizes the posture of the GND block and ensures constant electrical connection by restricting movement through guide pins and screws, and includes a surface GND rest member to maintain electrical contact with board GND electrodes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the GND block is made movable relative to the main block to enable board insertion and removal, then the ease of operation is improved, but the posture stability of the GND block deteriorates

Engineering Contradiction:
Improveboard insertion and removalVSAvoidposture stability of GND block
Core Design Contradiction:
Ease of operationVSStability of the object's composition

Solution Approach 1:

The GND block is designed to be movable relative to the main block through guide holes and guide pins, allowing dynamic adjustment for board insertion and removal while maintaining operational flexibility

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The coupling member is designed with an L-shaped asymmetric structure, where one end fits into a groove in the GND block and the other end fits into a groove in the operating member, creating stable positional relationships that prevent relative rotation while allowing linear movement

Inventive Principle:
Principle #4Asymmetry

2Ease of operation

If the coupling member allows relative movement between operating member and GND block, then the ease of operation is improved, but the reliability of electrical connection deteriorates

Engineering Contradiction:
Improveoperating member movementVSAvoidelectrical connection stability
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The L-shaped coupling member creates asymmetric constraints that allow movement in one direction (for operation) while preventing movement in perpendicular directions (maintaining electrical connection stability)

Inventive Principle:
Principle #4Asymmetry

Solution Approach 2:

The coupling member acts as an intermediary element that transmits movement from the operating member to the GND block while maintaining stable electrical connections through its groove-fitting structure

Inventive Principle:
Principle #24Intermediary (Mediator)
