Wrapping Medium With Tapered Adhesive Region
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional mediums for wrapping around cylindrical members, such as cables, often result in adhesive contact issues due to manual misalignment during wrapping, leading to unwanted adhesive contact with the wrapped member at the wrapping end.
Innovation Solution
The medium is designed with a specific shape and dimension configuration for its adhesive regions, including an inverted isosceles trapezoid shape for the adhesive region, where the length of the upper side is less than the lower side, and marks are strategically placed to guide proper alignment, reducing adhesive contact even with misalignment during wrapping.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual wrapping is performed, then the medium can be applied to the wrapped member, but misalignment occurs causing adhesive contact with the wrapped member
Solution Approach 1:
The adhesive region is designed with an inverted isosceles trapezoid shape where the upper side length is smaller than the lower side length. This preliminary geometric configuration ensures that even if misalignment occurs during manual wrapping, the adhesive portion does not extend beyond the wrapped member's surface, preventing unwanted adhesive contact.
2Device complexity
If the adhesive region has a rectangular shape, then the structure is simple, but misalignment causes adhesive exposure and contact with the wrapped member
Solution Approach 1:
The adhesive region employs an asymmetric inverted isosceles trapezoid shape instead of a symmetric rectangle. The upper base is shorter than the lower base, creating a tapered configuration that inherently prevents adhesive overflow and contact with the wrapped member during manual wrapping operations.
3Manufacturing precision
If marks are added for alignment guidance, then wrapping precision improves, but the medium structure becomes more complex
Solution Approach 1:
Visual marks are incorporated into the medium to guide proper alignment during wrapping. These marks provide clear visual cues for users to achieve correct positioning, improving wrapping precision without significantly complicating the overall medium structure.

AI summary
The object of the present disclosure is to reduce contact of adhesive on a wrapping-end end portion of a print label, with a wrapped member. A print label L includes a base layer 21 and a separation layer 24 stacked on each other. The print label L includes: an adhesive region D1; non-adhesive regions D2a, D2b in which a printing background layer 25 is provided; a non-adhesive region D3; a non-adhesive region D4; and an adhesive region D5. A length WA, in a second direction, of an other-side end portion of the adhesive region D5 in the first direction is less than a length W, in the second direction, of a one-side end portion of the non-adhesive region D3 in the first direction. A length WB, in the second direction, of a one-side end portion of the adhesive region D5 in the first direction is less than the length WA, in the second direction, of the other-side end portion of the adhesive region D5 in the first direction.
