Adhesive Sheet Peeling via Segmented Recess Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies face challenges in easily and efficiently peeling off sheet materials from components without causing damage, particularly during disposal or recycling, as they often require strong forces that can lead to tearing or uneven separation.
Innovation Solution
A component design featuring a first region with a recess for inserting a peeling tool and a second region not in contact with the adhesive surface, allowing for controlled peeling using leverage and distributed separation to prevent tearing, while also providing visual cues for tool insertion and reducing material costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If strong force is applied to peel off the sheet material, then the peeling speed increases, but the sheet material may tear or separate unevenly
Solution Approach 1:
The adhesive target region is divided into a first region with strong adhesive force and a second region with weak or no adhesive force. This segmentation allows the peeling process to start at the first region and progressively move to the second region, enabling controlled peeling that maintains both speed and quality without causing tearing or uneven separation.
2Strength
If the entire surface is made adhesive, then the sheet material adheres strongly, but it becomes difficult to peel off without tearing
Solution Approach 1:
Different regions of the adhesive target region are assigned different adhesive properties: the first region has strong adhesive force for secure attachment, while the second region has weak or no adhesive force for easy peeling. This local differentiation allows the sheet material to adhere strongly where needed while enabling easy peeling in the second region without requiring excessive force that could cause tearing.
3Ease of operation
If a recess is provided for peeling tool insertion, then controlled peeling is enabled, but the manufacturing complexity increases
Solution Approach 1:
The adhesive target region is segmented into functional zones (first region with strong adhesion, second region with weak adhesion) rather than adding complex mechanical structures. This segmentation achieves controlled peeling through the inherent adhesive property distribution, avoiding the need for recesses or specialized peeling tool interfaces, thereby maintaining manufacturing simplicity while enabling precise peeling control.

AI summary
A component has a surface to which a sheet material (100) having an adhesive surface is adhered, and an adhesive target region (R0) on a surface of the component (1), to which the sheet material (100) is adhered, is provided at the peripheral edge thereof with a first region (R1) and a second region (R2). The first region (R1) includes a recess (6) that allows a predetermined sheet material peeing tool (10) to be insertable to a side of the adhesive surface of the sheet material. The second region (R2) are positioned in the vicinity of the first region (R1), and includes a region not in contact with the adhesive surface of the sheet material (100) or a region mixedly including a part in contact with the adhesive surface and a part not in contact with the adhesive surface.
