Solution Overview
Problem
Existing cable feed-throughs face challenges in simple assembly and reliable sealing, as they often require complex assembly processes and may not ensure a secure seal.
Innovation Solution
A cable feed-through design featuring a split elastic sealing element with inner and outer sealing surfaces, combined with holding elements that can be assembled in a form-locking or material-locking manner, allowing for easy assembly and secure sealing of cables.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the sealing element is separated into two parts, then the assembly process becomes simpler and cables can be installed more easily, but the complexity of the sealing structure increases
Solution Approach 1:
The sealing element is divided into two separate sealing element parts (16a, 16b) that can be assembled independently. This segmentation allows the cable to be positioned and secured between the parts before final assembly, significantly simplifying the installation process while maintaining sealing integrity through the complementary contact surfaces (56a, 56b) that join the parts together.
2Reliability
If holding elements are used to secure the sealing parts, then the sealing reliability is improved, but the device complexity increases
Solution Approach 1:
The holding element parts (64a, 64b) are integrated with the sealing element parts (16a, 16b) to form unified cable feed-through parts (100a, 100b). This merging eliminates the need for separate holding mechanisms, reducing overall device complexity while maintaining reliable sealing through the combined structure that secures cables and provides sealing contact surfaces simultaneously.

AI summary
A cable feed-through with an elastic sealing element having at least one cable feed-through channel is provided. The elastic sealing element is assembled from two sealing element parts separated by a dividing surface and has a feed-through member which comprises the at least one cable feed-through channel and inner sealing surfaces which can abut sealingly on at least one cable sheath. At least one holding element is provided, with which the two sealing element parts can be acted upon in such a manner that the inner sealing surfaces abut sealingly on the cable sheath and the sealing element parts abut sealingly on one another with their contact surfaces respectively bordering on the dividing surface.
