Conical Cable Sealing Element for Variable Diameter Adaptation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cable sleeve sealing bodies require multiple segments with differently sized recesses to accommodate cables of various diameters, limiting flexibility and increasing storage needs.
Innovation Solution
A conically contoured recess between spring elements in the gel-like sealing element of the sealing body segment, allowing for sealing of cables with different diameters using a single segment, with the inner diameter tapering towards the compressive force direction, ensuring initial sealing and enhanced sealing upon compression.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple sealing body segments with differently sized recesses are used to accommodate cables of various diameters, then sealing effectiveness is improved, but device complexity and storage needs increase
Solution Approach 1:
The sealing body segment is designed with a conically contoured recess that can accommodate cables of various diameters within a range, making a single segment universal for multiple cable sizes. The conical shape allows the recess to adapt to different cable diameters, eliminating the need for multiple specialized segments for different cable sizes.
Solution Approach 2:
The recess contour is changed from cylindrical to conical, creating a gradient in the inner diameter that allows adaptation to different cable diameters. This parameter change in the recess geometry enables a single sealing body segment to effectively seal cables across a range of diameters.
2Ease of manufacture
If a constant inner diameter recess is used in the gel-like sealing element, then manufacturing is simplified, but adaptability to different cable diameters is reduced
Solution Approach 1:
The recess contour is changed from cylindrical to conical, creating a gradient in the inner diameter that allows adaptation to different cable diameters. This parameter change in the recess geometry enables a single sealing body segment to effectively seal cables across a range of diameters.
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
Increases flexibility by allowing a single sealing body segment to accommodate a range of cable diameters, ensuring effective sealing without the need for multiple segments, and allows for efficient use of sealing material.
Implementation Method 1
A spring element protrudes into the recess at both ends in order to center the cable to be sealed in the recess and to prevent the gel-like sealing element from flowing out during compression
Implementation Method 2
a force can be applied to one of the two end pieces via the pressure element in order to compress the gel-like sealing element

AI summary
The sealing body has a sealing body segment with gel type sealing element. The gel type sealing element is compressed during application of force by pressure-exerting element on a stable end piece, and hence restricting the gel type sealing element at one end. The recess of the sealing body of a cable sleeve is conically contoured between the two spring elements.
