Aperture-Linked Polymer Coating for Substrate Delamination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Outdoor objects, especially those with both external and internal surfaces, face rapid deterioration due to harsh weather conditions, as existing protective coatings tend to crack and peel away from the substrate over time.
Innovation Solution
A method involving the creation of apertures in a substrate that extend from one surface to another, allowing a polymer coating to fill and link the coatings on both surfaces, providing mechanical reinforcement and preventing delamination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a protective coating is applied to the external surface of a substrate, then the substrate is protected from harsh weather conditions, but the coating tends to crack and peel away from the substrate over time
Solution Approach 1:
The substrate is segmented by creating apertures that pass through it, allowing the coating to be divided into multiple sections that are mechanically interconnected. The coating is applied to both external and internal surfaces, with portions extending through the apertures to create a segmented yet unified protective system that resists cracking and peeling.
Solution Approach 2:
The coating structure is nested through the substrate apertures, with coating portions on the external surface, internal surface, and extending through the apertures forming a nested configuration. This nested arrangement creates mechanical interlocking that strengthens coating adhesion and prevents delamination.
2Ease of manufacture
If a protective coating is applied only to the external surface, then the application process is simpler, but the internal surface remains vulnerable to deterioration from trapped moisture and humidity
Solution Approach 1:
The coating system is segmented to include applications on both external and internal surfaces of the substrate, with apertures providing pathways for the coating to connect these surfaces. This segmentation allows comprehensive protection while maintaining a relatively simple application process by treating each surface independently.
Solution Approach 2:
The coating system serves multiple functions: protecting the external surface from weather, protecting the internal surface from moisture, and creating mechanical reinforcement through the apertures. This multi-functional approach addresses all surface vulnerabilities through a unified coating system.
3Reliability
If the coating is applied to both internal and external surfaces with extension through apertures, then the coating remains well-bonded and resistant to separation, but the manufacturing process becomes more complex
Solution Approach 1:
Apertures are created in the substrate before coating application, preparing the substrate in advance to receive and mechanically interlock the coating. This preliminary action simplifies the overall process by eliminating the need for post-coating reinforcement steps and ensuring reliable bonding from the start.
Solution Approach 2:
The coating application process merges multiple functions into a single step: coating the external surface, coating the internal surface, and creating mechanical reinforcement through aperture extension all occur simultaneously during one coating application process, reducing overall manufacturing complexity.

AI summary
A method for applying a polymer to a substrate having a first surface and a second surface (such as an inside surface and outside surface). One or more apertures are provided through the substrate, with the apertures linking the first and second surfaces. A polymer coating is applied to the first and second surfaces, with some of the polymer coating flowing into and remaining within the aperture(s). The polymer coating within the aperture(s) serves to link the polymer coating covering the first surface and the polymer coating covering the second surface. The invention also encompasses coated objects made using the inventive method.
