Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If welding connection is used for inner conductor and cable core, then electrical connection reliability is improved, but assembly automation difficulty increases and assembly efficiency decreases

Engineering Contradiction:

Improveelectrical connection reliabilityVSAvoidassembly efficiency

Core Design Contradiction:

ReliabilityVSProductivity

Solution Approach 1:

The patent replaces the welding process (thermal/chemical system) with a mechanical crimping connection system. The outer conductor is designed with a crimping structure that mechanically secures the cable core to the inner conductor, eliminating the need for welding equipment and processes while maintaining reliable electrical connection.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Ease of manufacture

If cover is added to facilitate welding, then assembly is facilitated, but the cover becomes loose and falls off in vibrating environment causing signal leakage

Engineering Contradiction:

Improveassembly facilitationVSAvoidsignal leakage prevention

Core Design Contradiction:

Ease of manufactureVSReliability

Solution Approach 1:

The patent removes the separate cover component entirely and integrates the protective function into the insulator body. The insulator is designed with an integrated structure that encloses and secures the inner conductor and cable core connection, eliminating the loose cover problem while maintaining protection against signal leakage.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The patent merges the cover function with the insulator body into a single integrated component. The insulator structure incorporates both insulation and protective enclosure functions, eliminating the need for a separate cover and ensuring reliable signal containment through the integrated design.

Inventive Principle:

Principle #5Merging (Combining)

3Reliability

If grounding elastic sheet is provided on outer conductor, then connection reliability is improved, but manufacturing cost increases and device complexity increases

Engineering Contradiction:

Improveconnection reliabilityVSAvoidstructure complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent merges the grounding function into the outer conductor body itself through an integrated L-shaped design. The outer conductor is formed as a single piece with built-in grounding pathways and structures, eliminating the need for separate grounding elastic sheets while maintaining reliable grounding and reducing overall device complexity.

Inventive Principle:

Principle #5Merging (Combining)

4Reliability

If grounding elastic sheet is provided on outer conductor, then connection reliability is improved, but available internal space is reduced

Engineering Contradiction:

Improveconnection reliabilityVSAvoidavailable internal space

Core Design Contradiction:

ReliabilityVSVolume of moving object

Solution Approach 1:

The patent removes the grounding elastic sheet component and integrates grounding functionality directly into the outer conductor structure. This eliminates the additional space required for separate grounding components while maintaining reliable grounding through the streamlined L-shaped outer conductor design.

Inventive Principle:

Principle #2Taking out (Extraction)

5Ease of manufacture

If multiple separate components are used for outer conductor and insulator, then manufacturing flexibility is improved, but assembly complexity increases

Engineering Contradiction:

Improvemanufacturing flexibilityVSAvoidassembly complexity

Core Design Contradiction:

Ease of manufactureVSDevice complexity

Solution Approach 1:

The patent merges the outer conductor and insulator into a single integrally molded L-shaped component. This unified structure is manufactured as one piece through injection molding, simultaneously achieving manufacturing flexibility and simplifying assembly by eliminating the need to assemble multiple separate components.

Inventive Principle:

Principle #5Merging (Combining)
