Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If phenyl silicone and hydrogenated polyisobutene are combined to provide gloss and adhesion, then gloss and adhesion are improved, but compatibility between components deteriorates
Solution Approach 1:
The patent introduces a specific compound as an intermediary substance that facilitates compatibility between phenyl silicone and hydrogenated polyisobutene. This intermediary acts as a bridge, allowing these two components to coexist stably while maintaining their respective functions of providing gloss and adhesion, thus resolving the contradiction between improving adhesion and maintaining compositional stability.
Solution Approach 2:
The patent modifies the molecular weight and structural parameters of the phenyl silicone and hydrogenated polyisobutene to achieve optimal compatibility. By carefully selecting and adjusting these parameters, the invention enables the components to be mutually soluble while preserving their functional properties, thereby resolving the compatibility issue without sacrificing adhesion performance.
2Reliability
If phenyl silicone and hydrogenated polyisobutene are combined to provide gloss and adhesion, then gloss and adhesion are improved, but feeling on use deteriorates
Solution Approach 1:
The specific compound introduced in the invention serves as a mediator that not only ensures compatibility between phenyl silicone and hydrogenated polyisobutene but also optimizes the sensory properties. This intermediary substance enables the formulation to maintain excellent adhesion while providing a pleasant feeling on application, thus resolving the contradiction between adhesion performance and user comfort.
3Reliability
If phenyl silicone and hydrogenated polyisobutene are combined to provide gloss and adhesion, then gloss and adhesion are improved, but storage stability deteriorates
Solution Approach 1:
The patent employs a specific compound as an intermediary that stabilizes the formulation during storage. This intermediary substance prevents degradation and maintains the stability of the combination between phenyl silicone and hydrogenated polyisobutene over time, ensuring that the product retains its adhesion properties and does not separate or deteriorate during storage, thus resolving the contradiction between adhesion performance and storage stability.
Solution Approach 2:
The invention adjusts the molecular weight and structural parameters of the components to optimize long-term stability. By carefully selecting and controlling these parameters, the patent ensures that the formulation remains stable during storage while maintaining excellent adhesion properties, thereby resolving the contradiction between adhesion performance and storage stability.
