Anti-adhesion Coating Composition for Public Facilities
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing solutions for preventing the adhesion of unlawful advertising materials on public and private facilities, such as street lights and traffic signals, are either costly or aesthetically unpleasing, and do not effectively prevent adhesion or allow for easy removal without specialized tools.
Innovation Solution
A coating composition comprising urethane or epoxy resin solutions, pigments, and beads, along with a second silicone-based release agent composition, is applied to form a layer that reduces adhesion and allows for easy removal of advertising materials without tools, while providing electrical insulation and matching the color of the facilities to maintain appearance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If rubber or synthetic resin sheets with projections are used to prevent adhesion of advertising materials, then adhesion prevention is improved, but device complexity and aesthetic appearance deteriorate due to required bands and fasteners
Solution Approach 1:
The patent replaces the mechanical sheet-and-fastener system with a chemical coating solution. The coating composition applied to the facility surface creates an anti-adhesion layer that prevents advertising material attachment without requiring any mechanical fasteners, bands, or additional structural components.
Solution Approach 2:
The patent uses a thin film coating applied directly to the facility surface. This flexible coating layer forms a continuous anti-adhesion barrier that conforms to the underlying surface geometry, eliminating the need for rigid sheets and their associated fastening systems.
2Reliability
If rubber or synthetic resin sheets with projections are used to prevent adhesion of advertising materials, then adhesion prevention is improved, but aesthetic appearance deteriorates due to exposed bands and fasteners
Solution Approach 1:
The patent replaces the mechanical sheet-and-fastener system with a chemical coating solution. The coating composition applied to the facility surface creates an anti-adhesion layer that prevents advertising material attachment without requiring any mechanical fasteners, bands, or additional structural components.
3Reliability
If dedicated teams continuously remove unlawful advertising materials, then adhesion prevention is improved, but cost increases significantly
Solution Approach 1:
The patent applies a preventive coating to the facility surface before advertising materials can be attached. This preliminary protective layer makes it difficult for adhesives to bond to the surface, preventing the need for subsequent removal operations and associated labor costs.
Solution Approach 2:
The patent transforms the normally adhesive surface into a non-adhesive surface by applying the coating. The harmful effect of adhesive bonding is converted into a beneficial anti-adhesion property, turning the surface characteristic that causes problems into the solution.
4Ease of manufacture
If conventional coating materials are used, then ease of application is improved, but adhesion prevention effectiveness deteriorates
Solution Approach 1:
The patent uses a composite coating composition containing multiple functional components: silicone oil or fluorocarbon resin for anti-adhesion properties, beads for texture and light reflection, and pigments for color matching. This composite formulation provides both ease of application like conventional coatings and superior adhesion prevention effectiveness.
Solution Approach 2:
The patent modifies the surface energy and physical properties of the coating by incorporating specific materials like silicone oil, fluorocarbon resin, and beads of particular sizes. These parameter changes create a surface that is both easy to apply and highly effective at preventing adhesion of advertising materials.
