Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If aerogel particles and binder resin are dispersed in a coating liquid, then the application target and applications are expanded, but the dispersibility of aerogel particles and binder resin becomes poor
Solution Approach 1:
The patent introduces a water-soluble polymer as an intermediary substance that mediates between the aerogel particles and binder resin. This polymer acts as a bridge, improving the dispersibility and compatibility of the components in the coating liquid, thereby resolving the contradiction between expanded applications and poor dispersibility.
Solution Approach 2:
The patent modifies the chemical and physical parameters of the coating liquid by adjusting the type and concentration of the water-soluble polymer, as well as the HLB value of the emulsifier. These parameter changes optimize the dispersibility and stability of the composite material in the coating liquid.
2Device complexity
If conventional coating liquids are used, then the formulation is simple, but the corrosiveness to metal increases
Solution Approach 1:
The water-soluble polymer serves as a protective intermediary that reduces the corrosiveness of the coating liquid to metal surfaces. It creates a protective layer or modifies the chemical environment, thereby reducing harmful effects while maintaining formulation simplicity.
Solution Approach 2:
The patent adjusts the chemical parameters of the coating liquid, specifically the pH value and the type of emulsifier used, to reduce corrosiveness to metal. These parameter modifications allow the coating liquid to maintain simplicity while reducing harmful effects on metal substrates.
3Reliability
If aerogel particles are dispersed in the coating liquid, then the heat insulating properties are improved, but the uniformity of dispersion becomes difficult to achieve
Solution Approach 1:
The water-soluble polymer acts as a mediator that facilitates uniform dispersion of aerogel particles throughout the coating liquid. It prevents aggregation and ensures even distribution, thereby achieving both improved heat insulating properties and uniform dispersion.
Solution Approach 2:
The patent performs preliminary actions by pre-dispersing the aerogel particles in the water-soluble polymer before incorporating them into the full coating liquid formulation. This preliminary dispersion ensures uniform distribution and prevents aggregation, achieving uniformity of dispersion while maintaining heat insulating properties.
