Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a silicone-based release agent is coated onto the surface of a plastic film, then release property is improved, but adhesion property deteriorates
Solution Approach 1:
The patent uses a composite release agent system combining silicone emulsion (for release property) with polyethylene-co-acrylic acid emulsion (for adhesion). This composite approach allows the release agent to simultaneously provide both release capability and strong adhesion to the plastic film, resolving the contradiction between ease of manufacture and strength.
2Reliability
If ionic conductive compounds are used as antistatic agents, then antistatic properties are improved, but stability deteriorates due to humidity dependence
Solution Approach 1:
The patent changes the fundamental parameter of conductivity mechanism from ionic conduction (humidity-dependent) to electronic conduction through π-conjugated polymers (humidity-independent). This parameter change transforms the antistatic agent from one that is unstable in varying humidity conditions to one that maintains stable conductivity, resolving the contradiction between reliability and stability.
3Stability of the object's composition
If π-conjugated electrically conductive polymers are used as antistatic agents, then stability is improved, but adhesion property deteriorates when combined with silicone-based release agent
Solution Approach 1:
The patent segments the release agent formulation into distinct functional components: silicone emulsion for release property, polyethylene-co-acrylic acid emulsion for adhesion, and π-conjugated polymer for antistatic properties. This segmentation allows each component to perform its specific function optimally without interfering with others, resolving the contradiction between stability and adhesion property.
4Loss of substance
If water-based emulsion type silicone is used as release agent, then solvent usage is reduced, but adhesion property deteriorates
Solution Approach 1:
The patent combines water-based silicone emulsion (reducing solvent usage) with polyethylene-co-acrylic acid emulsion (providing adhesion). This composite material approach allows the system to maintain low solvent content while achieving strong adhesion, resolving the contradiction between loss of substance and strength.
