Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a dye is used in a curable resin composition, then coloration is achieved, but heat resistance, solubility, coating uniformity and chemical resistance deteriorate
Solution Approach 1:
The patent uses a composite approach by combining a polymerizable compound with a dye to create a new compound that integrates both the functional properties of the polymer and the coloration properties of the dye. This composite structure allows the dye to maintain its coloration function while gaining the thermal and chemical stability of the polymer framework.
Solution Approach 2:
The patent modifies the chemical structure parameters of the dye by introducing specific polymerizable groups and functional groups at defined positions (R1-R6, R8-R11) within the dye molecule. This structural parameter change transforms the dye from a simple colorant into a functional polymer component that exhibits improved heat resistance, solubility, and chemical resistance while maintaining coloration.
2Productivity
If exposure time is reduced to improve productivity, then sensitivity must be improved, but developing performance deteriorates
Solution Approach 1:
The patent changes the sensitivity parameter of the curable resin composition by incorporating compounds with specific photopolymerization characteristics. The polymerizable compounds and photopolymerization initiators are selected to achieve optimal sensitivity, allowing faster exposure times while maintaining adequate developing performance through controlled polymerization kinetics.
3Productivity
If development time is reduced to improve productivity, then developability must be improved, but coating uniformity deteriorates
Solution Approach 1:
The patent modifies the developability parameter by selecting alkali soluble resins with specific molecular weights and structures that dissolve uniformly in the liquid developer. The polymerizable compounds are chosen to provide controlled dissolution rates, enabling faster development times while maintaining coating uniformity through homogeneous dissipation of the resin matrix.
