Pivotable Adhesive Connection Layout for Counterintuitive Peeling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing adhesive connection systems, particularly those used in sanitary products, are easily releasable by small children due to intuitive peeling methods, which do not require significant force, posing a safety risk.
Innovation Solution
A connection system with a pivotable adhesive means on a carrier element, where the pivotable part has a larger number of adhesive elements and is designed to require a counterintuitive peeling method, increasing the force needed for separation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If adhesive means are designed to be easily releasable by intuitive peeling, then ease of operation is improved, but safety deteriorates due to easy release by small children
Solution Approach 1:
The patent inverts the intuitive peeling direction by positioning the free end of the carrier element away from the user's natural grasping point. Instead of allowing peeling from the free end toward the connection region (which would be easy for children), the design requires grasping and pulling from the connection region toward the free end, making the release action counterintuitive and difficult for small children while still functional for adults.
2Reliability
If adhesive connection strength is increased to prevent easy release, then safety is improved, but ease of operation deteriorates due to difficulty in intentional release
Solution Approach 1:
The patent applies local quality by concentrating adhesive elements specifically in the connection region where the carrier element connects to the adhesive means. This localized adhesive placement creates a strong bond at the connection point while leaving the rest of the adhesive means relatively free. The free end of the carrier element is positioned to allow intentional release by pulling away from this concentrated adhesive region, maintaining ease of operation for adults while ensuring safety through strong local bonding.

AI summary
A connection system has a first adhesive which has a plurality of adhesive elements. The first adhesive has a first free end and a connection region, wherein the connection region is arranged or formed on a carrier element preferably designed as a flexible tape. A first pivotable part of the first adhesive is movable, in particular, pivotable, relative to the carrier element. The first pivotable part has free edges. In a state in which the first pivotable part is not pivoted relative to the connection region, i.e., in which both lie in a common plane, the free edges in the plane are not directly surrounded by adhesive elements of the first adhesive. The first pivotable part has, in particular, a larger number of adhesive elements than the connection region. A method for releasing such a connection system is disclosed, wherein the connection system has a second adhesive.
