Solution Overview

Problem

Existing coaxial connectors are insufficient for increasing signal transmission volume due to limited conduction modes, leading to inefficiencies as signal transmission demands grow.

Innovation Solution

A coaxial connector design featuring multiple signal junctions (first and second signal junctions) on its side surface, with a moving component that selectively connects to either the first or second signal junction, ensuring diverse and high throughput signal transmission without the need for manual wire stripping and soldering.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If traditional coaxial connector with single conduction mode is used, then structure is simple, but signal transmission volume is limited

Engineering Contradiction:

Improvesignal transmission volumeVSAvoidconnector structure

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The connector is divided into multiple independent signal transmission paths with separate signal junctions (first signal junction, second signal junction, third signal junction) and corresponding conduction modes. Each path can operate independently, enabling simultaneous multi-device connections and increasing overall signal transmission capacity without requiring complete redesign of the connector structure.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The connector body is designed to support multiple functions: it can establish conduction between first and second signal junctions, between second and third signal junctions, or between first and third signal junctions through the moving component. This multi-functionality allows a single connector structure to handle various connection scenarios and increase signal transmission volume.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If multiple signal junctions are added to increase conduction modes, then signal transmission diversity improves, but manufacturing precision requirements increase

Engineering Contradiction:

Improveconduction modesVSAvoidsignal junction positioning

Core Design Contradiction:

Adaptability or versatilityVSManufacturing precision

Solution Approach 1:

A moving component is introduced that can shift position to establish different conduction paths. This dynamic element allows the connector to switch between multiple conduction modes (first-conduction-mode, second-conduction-mode, third-conduction-mode) by moving the moving component to different positions, thereby achieving signal transmission diversity without requiring multiple fixed signal junctions that would demand high positioning precision.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The connector utilizes changes in the moving component's position parameter to switch between different conduction modes. By varying the position of the moving component along the connector body, different signal paths are activated, enabling multiple conduction modes with a single physical structure and reducing the need for precise positioning of multiple static junctions.

Inventive Principle:

Principle #35Parameter changes

3Reliability

If manual wire stripping and soldering is required, then connection flexibility is high, but operator consistency and signal status reliability decrease

Engineering Contradiction:

Improvesignal status consistencyVSAvoidconnection process

Core Design Contradiction:

ReliabilityVSEase of manufacture

Solution Approach 1:

The connector incorporates built-in signal junctions and conduction paths that automatically establish reliable electrical connections when components are assembled. The moving component and signal junctions are designed to self-align and make contact, eliminating the need for manual wire stripping and soldering operations. This self-service mechanism ensures consistent signal status regardless of operator skill level.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The manual mechanical process of wire stripping and soldering is replaced by a pre-engineered mechanical-electrical connection system. The connector uses integrated conductive paths and contact mechanisms that automatically establish electrical connections through simple assembly, replacing the complex manual electrical connection process with a more reliable and consistent mechanical insertion system.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

AI summary

A coaxial connector has a shell, a first signal junction, a second signal junction, a third signal junction, and a moving component. The first signal junction and the second signal junction are mounted on the side surface of the shell, and the third signal junction is mounted on the shell. When the moving component moves to the first position, the moving component is electrically connected to the first signal junction and the third signal junction. When the moving component moves to the second position, the moving component is electrically connected to the second signal junction and the third signal junction.
