Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If photo-catalyst is stuck on hollow members by ordinary bonding adhesive, then photo-catalyst can be attached to hollow members, but bonding adhesive undergoes oxidative decomposition leading to practical usability issues
Solution Approach 1:
The invention removes the bonding adhesive component from the system by using heat fusion to attach photo-catalyst particles directly to hollow members. This extraction eliminates the source of oxidative decomposition that was causing reliability issues, while still achieving the necessary attachment function through an alternative mechanism.
Solution Approach 2:
The invention introduces heat fusion as an intermediary mechanism to transfer photo-catalyst particles onto hollow members. This intermediary process replaces the problematic bonding adhesive, providing a stable attachment method that does not undergo oxidative decomposition.
2Ease of operation
If photo-catalyst is used to decompose organic substances and prevent pollution, then self-cleaning function is achieved, but resin decomposition occurs due to oxidative action
Solution Approach 1:
The invention creates local quality differentiation by concentrating photo-catalyst particles on the surface of hollow members rather than distributing them throughout the resin matrix. This localized placement enables self-cleaning functionality at the surface while protecting the bulk resin from oxidative decomposition.
Solution Approach 2:
The invention converts the potentially harmful oxidative action of photo-catalyst into a beneficial surface cleaning function. By directing the oxidative activity to the surface where dirt and pollution accumulate, the harmful effect is transformed into a useful self-cleaning mechanism that does not degrade the underlying resin.
3Temperature
If hollow members are used for heat insulation, then heat transfer coefficient is reduced, but surface dirt and stains lower reflectivity and heat insulation effect
Solution Approach 1:
The invention merges multiple functions into a single integrated system: hollow members provide heat insulation, while photo-catalyst particles attached to their surfaces provide self-cleaning functionality. This combination ensures that the heat insulation effect is maintained over time by automatically preventing surface pollution that would otherwise reduce reflectivity.
Solution Approach 2:
The invention ensures continuous useful action by providing ongoing self-cleaning functionality through photo-catalyst activity. This continuous surface maintenance preserves the heat insulation effect of hollow members over time, preventing the degradation that would occur from accumulated dirt and stains.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The paint achieves high heat insulation and self-cleaning effects with reduced resin decomposition, as the photo-catalyst is exposed on the surface for dirt decomposition and colloidal silica shields it from oxidative degradation, extending resin life and reducing the need for excessive photo-catalyst.

AI summary
Buildings surfaces are often seen subjected to application of heat insulation paint. When the surface of buildings gets dirty, reflectivity of the light lowers, so that the surface of buildings is likely to adsorb heat, resulting in lowering of the heat insulation effect. The present invention has such object of providing a paint that the tasks of prevention of getting dirty and provision of heat insulation are achieved, decomposition of resin is much lowered, and applying the paint is readily carried out. An emulsion type paint comprising: an organic hollow balloon A having on the surface photo-catalyst minute particles stuck by heat fusion, an organic hollow balloon B having on the surface minute particles other than photo-catalyst stuck by the similar manner, and an organic resin, colloidal silica, and water, characterized in that the organic hollow balloon B is higher in specific gravity than the organic hollow balloon A.
