Hooked Connecting Sheet Structure for Low-Noise Garment Peeling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional connecting sheets generate significant noise when peeled from garments due to the adhesive layer, necessitating a reduction in peeling noise.
Innovation Solution
A connecting sheet design featuring a sheet substrate with a first adhesive layer and protruding hook components, where the hook components' lower surfaces are covered with adhesive material, reduces noise by intermittent bonding and cushioning during peeling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a connecting sheet with adhesive layer is used to fix an article to a garment, then the article can be securely attached, but significant noise is generated when peeling the connecting sheet from the garment
Solution Approach 1:
The adhesive layer is segmented into multiple discrete hook components spaced at intervals across the sheet substrate. Each hook component includes a column portion and a head portion with adhesive material on its lower surface. This segmentation allows the adhesive force to be distributed across multiple discrete attachment points rather than a continuous layer, reducing the noise generated during peeling while maintaining secure attachment.
2Strength
If adhesive material is applied broadly to ensure strong bonding, then coupling force is improved, but adhesive contamination of packaging materials occurs
Solution Approach 1:
Adhesive material is applied locally only to the lower surface of the head portion of each hook component rather than across the entire sheet substrate. This localized adhesive application ensures strong bonding at the critical attachment points where the hooks engage with the garment, while preventing adhesive from spreading to and contaminating packaging materials during storage and handling.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The design effectively minimizes peeling noise while maintaining coupling force, eliminating the need for release liners, and preventing adhesive contamination of packaging materials.
Implementation Method 1
at least a lower surface of the head portion is covered with an adhesive material

AI summary
To provide a connecting sheet that can reduce noise generated when peeled from an object. A connecting sheet is a connecting sheet stacked on the object to be connected to the object, and includes: a sheet substrate having a first main surface and a second main surface; a first adhesive layer formed on the first main surface of the sheet substrate; and a plurality of hook components that protrude from the first main surface of the sheet substrate in a first direction and are spaced at intervals in a second direction in which the first main surface extends, and the hook components each includes: a column portion that extends from the sheet substrate in the first direction and protrudes from a surface of the first adhesive layer, and a head portion that extends from a tip of the column portion in the second direction, and the lower surface of the head portion is covered with the adhesive material.
