Thin Resin Film Wiping Sheet With Suction Adhesion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wiping sheets face issues of poor durability due to direct lamination of microfiber cloths with polymer sheets and limited flexibility when using resin films of 20-100 µm thickness, making them difficult to attach to concavo-convex surfaces and prone to peeling.
Innovation Solution
A reusable wiping sheet is designed with a microfiber cloth laminated on one side of a thin resin film (<20 µm) and an acryl-based polymer sheet with suction bubbles on the other, providing high adhesion strength and flexibility, allowing easy attachment to curved surfaces and repeated use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a polymer sheet is directly laminated with a microfiber cloth, then the structure is simple, but strength is insufficient and durability is poor
Solution Approach 1:
The invention uses a composite structure consisting of a polymer sheet layer and a microfiber cloth layer laminated together. This composite material approach provides both the simplicity of a two-layer structure and the durability of strong adhesion between the layers, resolving the contradiction between structural simplicity and adhesion strength.
2Volume of moving object
If a resin film of 20-100 μm in thickness is used as base material, then the structure is compact, but flexibility is poor and attachment onto concavo-convex surface is difficult
Solution Approach 1:
The invention employs a thin polymer sheet that functions as a flexible film, enabling the wiping sheet to conform to concavo-convex surfaces while maintaining a compact thickness. This flexible film approach resolves the contradiction between compactness and flexibility.
3Ease of operation
If a thin resin film of less than 20 μm is used, then flexibility is improved, but strength may be reduced
Solution Approach 1:
The invention creates a composite material system where a thin polymer sheet (less than 20 μm) is combined with a microfiber cloth layer. The thin polymer sheet provides flexibility while the microfiber cloth reinforces the overall strength, resolving the contradiction between flexibility and strength.
