Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If an aqueous base adhesive is used to eliminate organic solvent volatilization, then environmental safety is improved, but the adhesive is easily decomposed due to microorganisms
Solution Approach 1:
The patent extracts and removes the organic solvent component from the adhesive system, replacing it with an aqueous base. This eliminates the harmful volatilization of organic solvents while maintaining the adhesive's functional properties through careful selection of water-soluble or water-dispersible adhesive polymers and additives.
Solution Approach 2:
The patent introduces preservatives as intermediary substances that mediate between the aqueous adhesive and microorganisms. These preservatives prevent microbial decomposition of the adhesive while being compatible with the aqueous base, thus protecting the adhesive's stability without requiring organic solvents.
2Strength
If a base adhesive containing organic solvent is used to achieve appropriate adhesive strength and water resistance, then adhesive performance is improved, but environmental restrictions and safety concerns increase
Solution Approach 1:
The patent changes the fundamental parameter of the solvent base from organic to aqueous. This parameter change maintains the adhesive's ability to achieve appropriate adhesive strength and water resistance through careful formulation of the aqueous base and adhesive polymers, while eliminating environmental restrictions associated with organic solvent volatilization.
3Object-affected harmful factors
If ventilation requirements are imposed to handle organic solvent volatilization, then safety is improved, but device complexity and operational restrictions increase
Solution Approach 1:
The patent extracts the organic solvent component that causes ventilation requirements, replacing it with an aqueous base. This eliminates the need for complex ventilation systems and operational restrictions while maintaining safety by preventing harmful volatilization at its source.
