Layered Double-Sided Adhesive Pad for Repeated Reuse
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Adhesive sheet pads lose their adhesive functionality after being removed from a surface, limiting their reuse on multiple surfaces without a decrease in adhesion.
Innovation Solution
A multi-layer pad of double-sided adhesive sheet material with individual pull tabs, where each layer has different adhesive strengths, allowing for the exposure of fresh adhesive layers for repeated use by peeling off spent layers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single-layer adhesive sheet pad is used, then it provides initial adhesion functionality, but it loses adhesive strength after removal and cannot be reused effectively
Solution Approach 1:
The adhesive pad is divided into multiple layers, each containing fresh adhesive material. When one layer is removed from the surface, the user can peel it off and expose the next layer, which still has full adhesive strength. This segmentation allows the pad to maintain reliable adhesion across multiple reuse cycles.
Solution Approach 2:
Multiple layers of adhesive material are prepared in advance within the pad structure. Before the adhesive strength of the current layer degrades, subsequent fresh layers are already positioned and ready to be exposed and applied to surfaces, ensuring continuous adhesion capability.
2Productivity
If adhesive sheet pads are designed for single use, then manufacturing is simple, but productivity and resource efficiency decrease due to frequent disposal and replacement
Solution Approach 1:
The pad is segmented into multiple usable layers within a single product unit. This allows one physical pad to function as multiple adhesive sheets, increasing productivity by reducing the frequency of purchases and replacements while the added layer structure remains relatively simple to manufacture.

AI summary
A multi-layer pad of double-sided adhesive sheet material with individual pull-tabs. A method of making an adhesive sheet product may comprise: providing a first double-sided adhesive sheet having a first pull tab and a first adhesive strength on one side of the first double-sided adhesive sheet and a second adhesive strength on the other side of the first double-sided adhesive sheet; providing a second double-sided adhesive sheet having a second pull tab and a first adhesive strength on one side of the second double-sided sheet and a second adhesive strength on the other side of the second double-sided sheet; adhering the first double-sided adhesive sheet to the second double-sided sheet such that side with the second adhesive strength of the first double-sided adhesive sheet contacts the side with the first adhesive strength of the second double-sided adhesive sheet and such that the second pull tab is offset from the first pull tab; whereby a multi-layer double-sided adhesive pad is formed whereby the first double-sided adhesive sheet may be removed from the second double-sided adhesive sheet with the use of the first pull tab to expose the side having the first adhesive strength of the second double-sided adhesive sheet.
