Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cable bushing systems require complex assembly outside the wall opening, leading to restricted mobility of cables and increased tensile forces during installation, and the overall height is determined by screw length, limiting flexibility and ease of installation.
Innovation Solution
A modular cable bushing system where connecting means can be actuated both inside and outside the wall opening, allowing for flexible assembly and adjustment of module connections without requiring screws that dictate the overall height, enabling easier handling and reduced tensile forces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If cable bushing strip consists of multiple strip parts assembled outside the wall opening, then the passage openings can be formed and cables inserted, but the cables experience restricted mobility and increased tensile forces during installation
Solution Approach 1:
The cable bushing is divided into multiple modular strip parts that can be assembled in different configurations. These segments allow the passage openings to be positioned at various distances from the wall opening, enabling flexible cable routing and reducing tensile forces during installation.
Solution Approach 2:
The cable bushing system incorporates adjustable and movable components that allow the passage openings to be positioned dynamically at different locations. This dynamic positioning capability enables optimal cable routing and reduces restricted mobility during the installation process.
2Stability of the object's composition
If screw fastening is carried out through all strip parts, then the modules are securely connected, but the screw length determines the number of strip parts and overall height, limiting flexibility
Solution Approach 1:
The connection system is segmented into modular components where each strip part can be independently connected to others. This segmentation allows the overall height and number of strip parts to be adjusted according to specific installation requirements without being constrained by fixed screw lengths.
Solution Approach 2:
The connection mechanism uses adjustable parameters such as varying connection point positions and modular attachment methods that allow the overall height and configuration to be changed independently of the connection strength, providing greater versatility in installation scenarios.
3Stability of the object's composition
If complete assembly is performed outside the wall opening, then all strip parts can be positioned and connected, but the installation complexity increases and mobility is restricted
Solution Approach 1:
The assembly process is divided into separate manageable segments that can be prepared independently and then connected in place. This segmentation reduces the complexity of handling the entire assembly outside the wall opening while maintaining complete and stable connections.
Solution Approach 2:
Certain preparatory actions such as positioning and preliminary connection of strip parts can be performed in advance outside the wall opening, while the final assembly and securing is completed in place. This preliminary action reduces the complexity of the complete installation process.

AI summary
The invention relates to a cable feedthrough for mounting in a wall opening (1), comprising at least two mutually connectable modules (5, 6, 7) and at least one through-hole through which a cable can be passed, wherein in the assembled condition the through-hole is formed by recesses (2, 3) in two adjacent modules (5, 6, 7). To facilitate installation of cables in the cable feedthrough and of the cable feedthrough in the wall opening, and also to ensure that the cable feedthrough is not restricted to a predetermined overall height, the modules (5, 6, 7) have connecting means (8, 9) for establishing a frictional and/or interlocking connection between two adjacent modules (5, 6, 7), and when two adjacent modules (5, 6, 7) are connected the cable is clamped.
