Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sealing solutions for cable bushings are time-consuming to apply, expensive to produce, and limited in their adaptability to various cable diameters, leading to high production and storage costs.
Innovation Solution
A sealing sleeve that can be easily punched out from a carrier material with an adhesive layer, featuring a slit or predetermined breaking point for quick assembly, allowing it to be adapted to multiple cable diameters without the need for complex manufacturing processes or molds, and can be used for multiple lines in a single application.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If preformed sealing sleeves are used, then sealing reliability is improved, but production cost increases due to complex manufacturing processes and mold requirements
Solution Approach 1:
The sealing sleeve is designed as a flat, two-dimensional element with adhesive layers on both sides, segmented from the complex three-dimensional preformed sleeves. This segmentation allows the sealing function to be achieved through a simple flat structure that can be punched out using standard tools, eliminating the need for expensive molds while maintaining sealing effectiveness through the adhesive bonding mechanism.
2Adaptability or versatility
If different sizes of sealing sleeves are produced for various cable diameters, then adaptability is improved, but storage cost and capital commitment increase
Solution Approach 1:
The flat sealing sleeve design with adhesive layers serves multiple functions and can be adapted to different cable diameters through a single universal product. The sleeve can be punched in various sizes from a continuous strip or sheet, allowing one base design to serve multiple applications. This universality eliminates the need to stock multiple preformed sleeve sizes, reducing storage requirements and capital commitment while maintaining adaptability to different cable dimensions.
3Reliability
If multiple pieces of adhesive tape are applied in a scale-like manner, then sealing effectiveness is improved, but processing time increases
Solution Approach 1:
Multiple separate adhesive tape pieces applied in a scale-like manner are merged into a single continuous flat sealing sleeve with adhesive layers on both sides. This merging combines the sealing function of multiple tapes into one integrated element that can be applied in a single operation, dramatically reducing processing time while maintaining the same sealing effectiveness through the continuous adhesive bonding across the entire sealing surface.
4Reliability
If preformed sealing sleeves with grommets and collars are used, then airtight sealing is improved, but device complexity increases
Solution Approach 1:
The complex grommet and collar components are extracted and replaced by a simplified flat sealing sleeve structure. The sealing function previously achieved through multiple assembled parts (grommet, collar, adhesive) is now achieved through a single flat element with adhesive layers, maintaining airtight sealing through the adhesive bonding while eliminating the structural complexity of multiple components and their assembly requirements.

AI summary
The sleeve (1) has a break section or slot (7) adhered with one another on two sides of a separation mark by deformation. The slot is provided in a support material (4) and a glue layer, where the support material consists of non-woven fabric or plastic coated non-woven fabric and a plastic film. The glue layer is covered on a side of a cuff by a liner. The liner comprises two parts arranged in an overlapping manner. The cuff comprises a recess in center (9), and the support material is formed in a waterproof manner and/or by addition of a UV-resistant UV protection unit. An independent claim is also included for a system comprising a sealing sleeve and a spacer.
