Compression Wedge Distinct Stops for Seal Force
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lead-through systems lack distinct stops for the compression wedge, making it difficult to determine if the desired compression force has been achieved without measuring, risking either inadequate or excessive force application.
Innovation Solution
A compression wedge with distinct stops at its extreme positions, achieved through co-operating stop edges on the screw and socket, ensuring clear indication of end positions without the need for measurement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the compression wedge uses screws without distinct stops, then the structure remains simple, but it becomes difficult to determine if the desired compression force has been achieved
Solution Approach 1:
The compression wedge system performs its own measurement function through the distinct stops on the screws. The stops automatically indicate when the predetermined compression force has been achieved, eliminating the need for external measurement tools or complex measurement mechanisms. The system serves itself by incorporating the measurement indication directly into the compression mechanism.
Solution Approach 2:
The patent replaces complex measurement systems with a simple mechanical indication system. Instead of using sophisticated sensors, gauges, or measurement devices to determine compression force, the invention uses distinct mechanical stops that provide clear visual or tactile signals when the predetermined force is reached. This substitutes a complex measurement system with a simple mechanical indication system.
2Reliability
If the compression force is applied without distinct stops, then the operation is faster, but there is a risk of inadequate or excessive compression force
Solution Approach 1:
The distinct stops on the screws provide self-service by automatically indicating when the correct compression force has been applied. The operator does not need external guidance or complex procedures - the stops themselves provide the necessary information to ensure proper seal tightness, making the system self-regulating and reliable.
Solution Approach 2:
The distinct stops provide immediate visual or tactile feedback to the operator about the compression force status. When the screw reaches the stop, it clearly indicates that the predetermined compression force has been achieved. This feedback mechanism ensures reliable seal tightness by preventing both inadequate compression (before the stop) and excessive compression (beyond the stop).
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables precise control of compression force application, ensuring a tight seal is maintained without manual measurement, enhancing usability and reducing the risk of over-compression.
Implementation Method 1
The wedge is a compression means which is to compress the modules in order for them to seal inwardly against the pipe, cable or wire
Implementation Method 2
the wedge is moved between a non-compression state and a compression state by means of two screws, whereby each screw has threads with opposite pitches
Implementation Method 3
The screws are connected to two wedge elements, which are moved towards each other if the screws are turned in a first direction and away from each other if the screws are turned in the opposite direction

AI summary
The present invention concerns a compression wedge of a lead-through system. The wedge is moveable between two extremes and has distinct stops at the extremes. The distinct stops are given by co-operating stop edges (16, 17, 18, 23). In one embodiment two of the stop edges (16, 17) are provided on a screw (6). One end of the screw (6) is received inside a socket (7) fastened to a first wedge element (1). A second end of the screw (6) is fastened to a second wedge element (2). The socket (7) and screw (6) are mutually moveable in an axial direction of the screw (6). One stop edge (23) is provided in an inner opening (35) of the socket (7) and one stop edge (18) is provided in an opening of the first wedge element (1).
