Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If soldering is used to connect antenna cable to connector, then electrical connection reliability is improved, but manufacturing complexity and labor cost increase due to requiring skilled operators

Engineering Contradiction:

Improveelectrical connection reliabilityVSAvoidmanufacturing process complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent replaces the soldering process (thermal/chemical joining method) with a mechanical compression connection system. The connection body compresses the connector and cable assembly together using a compression member, eliminating the need for soldering skills and equipment while maintaining reliable electrical connection.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent introduces a connection body as an intermediary component that mediates between the connector and cable. This connection body provides a standardized interface and compression mechanism, simplifying the manufacturing process by replacing complex manual soldering operations with a plug-and-play assembly process.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Strength

If excessive solder is used for connection, then connection strength is improved, but product weight increases

Engineering Contradiction:

Improveconnection strengthVSAvoidproduct weight

Core Design Contradiction:

StrengthVSWeight of moving object

Solution Approach 1:

The patent replaces solder material (which adds weight) with a mechanical compression system. The connection strength is achieved through compression force applied by the compression member rather than through solder volume, significantly reducing the weight of the connection assembly.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Reliability

If manual soldering process is used, then connection reliability is improved, but manufacturing time and labor cost increase

Engineering Contradiction:

Improveconnection reliabilityVSAvoidmanufacturing efficiency

Core Design Contradiction:

ReliabilityVSProductivity

Solution Approach 1:

The patent replaces the manual soldering process with an automated-friendly mechanical compression system. The standardized connection body and compression member design allow for quick assembly without skilled operators, dramatically improving manufacturing efficiency while maintaining connection reliability.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The compression connection system is designed to be self-aligning and self-securing. When the compression member is engaged, it automatically applies the necessary compression force to secure the connector and cable, eliminating the need for operator skill judgment and reducing assembly time.

Inventive Principle:

Principle #25Self-service

AI summary

An antenna cable connection module in accordance with the present disclosure includes an antenna cable for forming a contact point connected to an antenna filter part; a body part located on the outer circumferential surface of the antenna cable, and inserted into a receiving port located on the antenna filter part together with the end portion of the antenna cable and coupled to the antenna filter part; and a bush interposed between the antenna cable and the body part, and having an inclined surface having a slope in a longitudinal direction formed thereon to strengthen the coupling between the antenna filter part and the antenna cable. As a result, it is possible to constitute a simple antenna cable connection module of a ground contact type, thus providing a device reducing the failure occurrence rate. In addition, it is possible to constitute a simple antenna cable connection module for an operator to easily operate, thus reducing the labor cost and saving the time consumed for an antenna cable connection.
