Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If epoxy resin is used as the main component, then certain degree of moisture resistance is achieved, but flexibility and design freedom are restricted

Engineering Contradiction:
Improveflexibility and design freedomVSAvoidmoisture resistance
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The patent changes the resin type parameter from epoxy to silicone, which fundamentally alters the material's flexibility and design adaptability. Silicone resin provides better flexibility and formability while simultaneously achieving superior moisture resistance, thus improving both sides of the contradiction

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent applies silicone resin specifically in applications requiring high moisture resistance and flexibility (such as conductive resin layers in electronic components), allowing each application to have the optimal material properties for its specific requirements rather than using a universal epoxy resin for all cases

Inventive Principle:
Principle #3Local quality

2Productivity

If conductive resin layer is formed to improve moisture resistance, then manufacturing efficiency is enhanced, but design and manufacturing restrictions remain

Engineering Contradiction:
Improvemanufacturing efficiencyVSAvoiddesign and manufacturing flexibility
Core Design Contradiction:
ProductivityVSAdaptability or versatility

Solution Approach 1:

The patent changes the resin composition parameters to use silicone resin with specific content ratios (50-100 parts by mass per 100 parts by mass of conductive filler), which improves manufacturing efficiency through better processability while simultaneously reducing design and manufacturing restrictions due to enhanced flexibility and formability

Inventive Principle:
Principle #35Parameter changes
