Cable Feed-Through Insert With Sealed Multi-Cable Membrane
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cable feed-through solutions for walls do not efficiently guide multiple cables through a wall opening while maintaining a seal, lacking a simplified and effective method for cable insertion and sealing.
Innovation Solution
An insertion component comprising a frame element made of hard material and a membrane of soft material, with a fastening device and cable receptacles distributed over the membrane, allowing for secure and sealed cable passage through a wall opening, utilizing push-through membrane portions and cable grommets for traction relief.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a traditional cable feed-through solution is used, then a wall opening can be sealed, but multiple cables cannot be efficiently guided through while maintaining a seal
Solution Approach 1:
The cable feed-through is segmented into multiple independent cable receptacles distributed over the membrane surface, each capable of accommodating individual cables. This segmentation allows multiple cables to pass through while maintaining the overall seal integrity of the membrane.
Solution Approach 2:
A flexible membrane made of soft material forms the sealing surface, replacing rigid sealing structures. The membrane can deform to accommodate multiple cables while maintaining fluid-tight sealing, enabling both high adaptability and sealing reliability.
2Ease of operation
If cable receptacles are open from the beginning, then cable insertion is easy, but the membrane remains exposed and cannot remain closed for protection
Solution Approach 1:
The cable receptacles are pre-formed with closed push-through membrane portions before cable installation. This preliminary configuration maintains membrane protection while enabling straightforward cable insertion by simply pushing through the pre-positioned membrane sections.
3Strength
If a hard frame element is used, then structural support is provided, but the sealing surface lacks flexibility
Solution Approach 1:
The cable feed-through combines a hard frame element made of rigid material with a soft membrane made of flexible material. This composite structure provides both the structural support from the rigid frame and the sealing flexibility from the soft membrane, resolving the contradiction between strength and adaptability.
