Integrated Compression Frame for Cable Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cable and pipe transition systems have complexity in manufacturing, handling, and storage due to separate compression units and modules, which increases the number of loose parts and complicates the process.
Innovation Solution
Integrating the compression unit into the frame as a single, unified component, allowing for a common manufacturing process with the frame and optional seal, reducing the number of loose parts and simplifying handling and storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate compression units and modules are used, then effective sealing capabilities are achieved, but device complexity and number of loose parts increase
Solution Approach 1:
The compression unit is integrated directly into the frame structure, merging two previously separate components (frame and compression unit) into a single unified structure. This reduces the number of loose parts while maintaining the sealing function, as the compression elements are now fixed within the frame rather than being separate removable units.
2Reliability
If separate compression units and modules are used, then effective sealing capabilities are achieved, but manufacturing and handling complexity increase
Solution Approach 1:
The frame and compression unit are manufactured as a single integrated component, combining two manufacturing processes into one. This simplifies the manufacturing workflow, reduces assembly steps, and improves ease of manufacture while preserving the sealing functionality through the integrated compression elements.
3Reliability
If separate compression units and modules are used, then effective sealing capabilities are achieved, but handling and storage difficulty increase
Solution Approach 1:
The integration of the compression unit into the frame creates a single handling unit rather than multiple separate components. This reduces the number of parts that need to be managed during handling and storage, improving ease of operation while maintaining the sealing capability through the fixed compression elements within the frame structure.

Function Achieved in This Case
This integration simplifies the manufacturing and handling of cable and pipe transitions by reducing the number of loose parts, facilitating easier assembly and storage while maintaining effective sealing capabilities.
Implementation Method 1
The compression unit is placed between the frame and the modules in such a way that when the compression unit is expanded the compressible modules will be compressed around the cables, wires or pipes

AI summary
The present invention concerns a frame (1, 12, 19) receiving one or more modules (2, 22) for cable entries or pipe penetrations. A compression unit (8, 23) is an integrated part of the frame (1, 12, 19), which compression unit (8, 23) is to compress the modules (2, 22) inside the frame (1, 12, 19). The compression unit (8, 23) comprises three compression wedges (9-11, 25, 26). An upper and a lower compression wedge (9, 10, 25) have the same orientation, while a middle compression wedge (11, 26) has an opposite orientation. The middle compression wedge (11, 26) is oriented with a broad side (31) facing an opening (3, 13) of the frame (1, 12, 19) receiving the modules (2, 22). At least one compression screw (7, 24) goes through openings (32) of the upper and lower compression wedges (9, 10, 25) and through a slot (34) in the middle compression wedge (11, 26).
