Adhesive Tape Laminate for Elongated Object Wrapping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for creating wraps for elongated objects, such as cable sets, are complex and costly due to the need for multiple adhesive tapes with adhesive coatings, which complicates handling and production.
Innovation Solution
A method involving a single adhesive tape with a first adhesive coating on its outer face and a second adhesive coating applied to the inner face of the base strip, combined with an adhesive-free overlay strip, simplifies the process by eliminating the need for multiple adhesive tapes and allowing for easier bonding and secure closure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple adhesive tapes with adhesive coatings are used, then mechanical protection is achieved, but production complexity and costs increase
Solution Approach 1:
The patent combines multiple adhesive tapes into a single laminate structure consisting of a base strip with first adhesive coating and an overlay strip with second adhesive coating. This merging reduces the number of separate adhesive tape applications needed while maintaining the mechanical protection function through the integrated laminate structure.
Solution Approach 2:
The laminate is segmented into functional layers: a base strip with first adhesive coating for initial bonding, an overlay strip with second adhesive coating for closure, and exposed edge bands for fixation. This segmentation allows each layer to perform its specific function efficiently within a unified structure.
2Reliability
If multiple adhesive tapes are used, then secure bonding is achieved, but handling and production become more difficult
Solution Approach 1:
Multiple adhesive tapes are merged into a single pre-assembled laminate unit that can be handled as one piece. The base strip and overlay strip are already bonded together in the correct configuration, eliminating the need for separate handling and application of multiple adhesive tapes during production.
Solution Approach 2:
The laminate is prepared in advance with the base strip and overlay strip already bonded together in the correct configuration. This preliminary assembly of adhesive layers eliminates the need for complex handling and sequential application during production, making the process simpler and more efficient.
3Reliability
If adhesive tapes are applied with offsets, then protection from mechanical damage is achieved, but the number of procedural steps increases
Solution Approach 1:
The offset arrangement of adhesive tapes is merged into a single laminate structure where the base strip and overlay strip are pre-positioned with the correct offset. This eliminates the need for multiple separate application steps during production, as the offset configuration is already established in the pre-assembled laminate.
Solution Approach 2:
The offset positioning required for mechanical damage protection is performed in advance during laminate manufacturing. The base strip and overlay strip are bonded together with the correct offset configuration before application to the elongated object, eliminating the need for complex positioning steps during production.
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
This approach reduces production complexity and costs while providing effective mechanical protection for elongated objects by creating a durable and secure wrap with exposed edge bands for fixation and closure.
Implementation Method 1
applying the adhesive tape with its first adhesive coating to the overlay strip along at least one of its two longitudinal edges
Implementation Method 2
the base strip of the adhesive tape is furnished essentially over a partial area with another second adhesive coating in addition to the first adhesive coating on its inner face

AI summary
A sheath for wrapping an elongated object is formed by an adhesive tape having a base strip having inner and outer faces, a first adhesive on the outer face, an adhesive-free overlay strip adhered to the first adhesive coating so as to leave a first exposed edge band on at least one of two longitudinal edges of the tape, and a second adhesive layer covering only part of an area of the inner face.
