Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If spray application method is used for hydrophobic composition, then large surfaces can be treated efficiently, but overspray occurs on small optical surfaces causing material waste
Solution Approach 1:
The invention extracts only the necessary portion of hydrophobic composition and applies it directly to the applicator tip, eliminating the spray mechanism that causes overspray. The composition is transferred from the reservoir to the tip through capillary action or pressure, ensuring precise delivery only where needed on small optical surfaces.
Solution Approach 2:
The applicator tip acts as an intermediary between the hydrophobic composition reservoir and the optical surface. It controls the transfer and deposition of the composition, allowing precise application to small surfaces without the overspray problems inherent in direct spray methods.
2Ease of operation
If conventional spray and wipe method is used, then application is simple, but adhesion to polymeric substrates is poor
Solution Approach 1:
The invention changes the chemical parameters of the hydrophobic composition by using metal silicon complexes instead of conventional polysiloxanes. This chemical modification enables the composition to adhere properly to polymeric substrates while maintaining ease of application through the applicator system.
Solution Approach 2:
The hydrophobic composition uses composite metal silicon complex materials that combine the benefits of silicon-based hydrophobicity with metal coordination chemistry, creating a formulation that adheres well to both glass and polymeric substrates while being easily applicable.
3Object-affected harmful factors
If hydrophobic coating is applied to small optical surfaces, then protection against dirt and smudging is improved, but the coating lacks permanency
Solution Approach 1:
The invention changes the chemical composition parameters by using metal silicon complexes that form more permanent bonds with substrates. The metal-silicon coordination chemistry creates stronger adhesion and more durable coatings that last longer than conventional polysiloxane-based hydrophobic coatings.
