Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a curable composition containing an ene compound and a thiol compound is used, then adhesiveness is improved, but adhesive strength decreases over time
Solution Approach 1:
The patent changes the molecular weight parameter of the thiol compound, specifically using a thiol compound with a molecular weight of 100 or more, to optimize the balance between initial adhesiveness and long-term durability of the adhesive strength
Solution Approach 2:
The patent creates a composite curable composition system combining an ene compound and a thiol compound with specific molecular weight characteristics to achieve both good adhesiveness and sustained adhesive strength over time
