Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the external diameter of the conductive contact is reduced to enable high-frequency signal handling and miniaturization, then the adaptability to high-frequency signals and miniaturization is improved, but the durability and ease of assembly deteriorate

Engineering Contradiction:

Improveadaptability to high-frequency signals and miniaturizationVSAvoiddurability

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The conductive contact is divided into two functional parts: a thin-walled tubular body for high-frequency signal handling and a separate solid base for mechanical strength and assembly. This segmentation allows each part to be optimized independently - the tubular body maintains small diameter for miniaturization while the solid base provides durability for assembly.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Different parts of the conductive contact have different structural qualities: the tubular body portion has thin walls for electrical performance and miniaturization, while the base portion has solid structure for mechanical strength. This local quality differentiation resolves the contradiction between small diameter and durability.

Inventive Principle:

Principle #3Local quality

2Adaptability or versatility

If the external diameter of the conductive contact is reduced to enable miniaturization, then the adaptability to miniaturized circuits is improved, but the ease of assembly deteriorates due to deformation during assembly

Engineering Contradiction:

Improveadaptability to miniaturized circuitsVSAvoidease of assembly

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

By segmenting the conductive contact into a thin-walled tubular body and a solid base, the assembly process becomes easier because the solid base provides structural integrity during handling and insertion, preventing deformation of the critical thin-walled signal-conducting portion.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The solid base is formed in advance as part of the integrated structure, providing pre-established mechanical support that prevents deformation during the assembly process, thereby facilitating easier assembly of miniaturized components.

Inventive Principle:

Principle #10Preliminary action

3Adaptability or versatility

If a thin-walled tubular body is used for the conductive contact to achieve small diameter, then the adaptability to high-frequency signals is improved, but the manufacturing precision and durability worsen due to deformation during assembly

Engineering Contradiction:

Improveadaptability to high-frequency signalsVSAvoidmanufacturing precision and durability

Core Design Contradiction:

Adaptability or versatilityVSManufacturing precision

Solution Approach 1:

The conductive contact is segmented into a thin-walled tubular body for high-frequency signal conduction and a solid base for mechanical stability. This segmentation allows the thin-walled portion to maintain manufacturing precision by being supported by the rigid base during assembly, preventing deformation that would compromise manufacturing quality.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The conductive contact combines two structural forms (thin-walled tubular and solid) into an integrated composite structure, where the solid base compensates for the structural weakness of the thin-walled portion, maintaining manufacturing precision and durability while enabling high-frequency signal handling.

Inventive Principle:

Principle #40Composite materials
