Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sealing devices for electrical lines are limited in their ability to accommodate lines of different diameters, requiring multiple seals with varying diameters for a compact and sealed arrangement, which is inefficient and not universally applicable.
Innovation Solution
A plug arrangement featuring two elastic sealing elements with multiple through-openings of varying diameters, including a first sealing device as a rubber grommet and a second sealing element with radially circumferential sealing lamellae, allowing for adaptation to different line diameters and incorporating an optional intermediate sleeve for seamless transitions, ensuring a reliable and compact sealing solution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a collecting mat seal with fixed diameter through-openings is used, then a compact sealed arrangement is achieved, but the sealing device cannot accommodate lines of different diameters
Solution Approach 1:
The sealing device is designed to accommodate multiple line diameters through a single universal structure. The collecting mat seal includes through-openings of different diameters (first, second, and third diameters) that can seal lines of varying sizes, eliminating the need for multiple specialized seals for different cable diameters.
Solution Approach 2:
The sealing device is divided into multiple functional components: a first sealing element with a first through-opening for larger lines, a second sealing element with a second through-opening for medium lines, and a third sealing element with a third through-opening for smaller lines. This segmentation allows each element to be optimized for specific diameter ranges while forming a unified sealing system.
2Reliability
If rigid walls are used in the receiving space, then structural stability is achieved, but the sealing requires special adaptation of size
Solution Approach 1:
The sealing elements utilize elastic material properties to change their dimensional parameters dynamically. The elastic sealing elements can deform to accommodate different line diameters while maintaining sealing pressure, allowing the same receiving space to seal various sizes without special manufacturing adaptations.
Solution Approach 2:
The sealing elements are made from elastic material that forms flexible sealing surfaces. These flexible elements can adapt their shape and size to match different line diameters, providing reliable sealing against rigid walls without requiring the receiving space to be specially adapted for each size.
3Adaptability or versatility
If multiple different collecting mat seals are used for different diameters, then compact arrangement is achieved, but device complexity and cost increase
Solution Approach 1:
Multiple sealing functions are merged into a single integrated collecting mat seal structure. The seal incorporates through-openings of different diameters within one component, combining what would traditionally require multiple separate seals into a single universal sealing device.
Solution Approach 2:
A single collecting mat seal design serves multiple diameter requirements by incorporating first, second, and third through-openings with different diameters. This universal seal replaces the need for multiple specialized seals, reducing both the quantity of components and overall system complexity.

AI summary
The arrangement has a sealing device (10) for sealing electrical lines (2), and an elastic sealing element (25) with an opening through which the electrical lines are passed. The electrical line at an outer circumference is arranged in sealing contact with the sealing element. Another sealing element receives the former sealing element and is formed as an elastic element with a passage opening (14). The passage opening and another passage opening are provided for passing the electrical lines. The passage openings exhibit different dimensions.
