Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If insulative materials (plastic) are used for the tongue portion, then the device complexity is reduced and ease of manufacture is improved, but the reliability deteriorates due to melting at high temperatures

Engineering Contradiction:
Improveease of manufactureVSAvoidresistance to high temperature
Core Design Contradiction:
Ease of manufactureVSReliability

Solution Approach 1:

The patent applies composite materials by combining ceramic material for the tongue portion with metal shielding plates and insulative housings. The ceramic material provides high-temperature resistance while the metal components provide shielding and structural support, creating a composite structure that solves both the manufacturing ease and high-temperature reliability requirements.

Inventive Principle:
Principle #40Composite materials

Solution Approach 2:

The patent changes the material parameter from plastic to ceramic for the tongue portion. This parameter change increases the melting point and thermal stability of the component, allowing it to withstand high temperatures during high-current transmission without deforming or melting.

Inventive Principle:
Principle #35Parameter changes

2Reliability

If ceramic materials are used to replace insulative materials, then the reliability is improved by preventing melting at high temperatures, but the ability to shield high frequency signal interference deteriorates

Engineering Contradiction:
Improveresistance to high temperatureVSAvoidhigh frequency signal interference
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent introduces metal shielding plates as intermediary elements between the ceramic tongue portion and the external environment. These shielding plates act as mediators that block high-frequency electromagnetic interference while allowing the ceramic material to maintain its high-temperature resistance function.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent creates a composite structure where ceramic material provides thermal stability and metal shielding plates provide electromagnetic interference protection. This composite approach allows both high-temperature reliability and high-frequency shielding to be achieved simultaneously.

Inventive Principle:
Principle #40Composite materials

3Object-affected harmful factors

If metal shielding plates are added to shield high frequency interference, then the shielding capability is improved, but the device complexity increases

Engineering Contradiction:

Core Design Contradiction:
Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The patent merges the shielding function with the existing structural components by integrating metal shielding plates into the housing and contact module assembly. This combining approach provides shielding capability while minimizing the increase in device complexity through functional integration.

Inventive Principle:
Principle #5Merging (Combining)
