Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing wall ducts for routing cables through building walls are time-consuming to install and require multiple steps, with potential errors in sealing compound application and filling with casting resin, leading to unsatisfactory storage and handling of materials.
Innovation Solution
A wall duct with a rubber-elastic molded part and integrated sleeve-like connecting element that eliminates the need for sealing compound and casting resin, featuring a socket-like connecting element divided lengthwise and dovetail guides for easy assembly and visual inspection of gas-tight connections, along with rib-shaped projections for secure handling and locking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If sealing compound and casting resin are used to ensure gas-tight connection, then sealing reliability is improved, but installation time and complexity increase
Solution Approach 1:
The patent extracts and eliminates the sealing compound and casting resin from the installation process. Instead of using these separate sealing materials, the invention integrates a rubber-elastic molded part directly into the pipe socket that provides sealing functionality without requiring additional sealing compounds or resin filling operations.
Solution Approach 2:
The patent merges the sealing function with the structural pipe socket component. The rubber-elastic molded part is integrated into the pipe socket to form a unified component that combines mechanical support and sealing functions, eliminating the need for separate sealing materials and operations.
2Reliability
If sealing compound and casting resin are applied for perfect sealing, then sealing reliability is improved, but potential for installation errors increases
Solution Approach 1:
The rubber-elastic molded part is designed to automatically provide sealing when the pipe socket is installed. The elastic material deforms to conform to the cable or conduit, creating a seal without requiring manual application of sealing compound or monitoring of resin curing, thereby eliminating installation errors related to these materials.
Solution Approach 2:
The patent changes the physical state and properties of the sealing mechanism from chemical (sealing compound and resin) to mechanical (rubber-elastic deformation). The elastic molded part uses material elasticity to provide sealing, transforming the sealing mechanism from a chemical process requiring careful application to a mechanical process that is more forgiving and easier to install correctly.
3Reliability
If multiple sealing materials and components are used, then sealing reliability is improved, but storage and handling difficulty increases
Solution Approach 1:
The patent combines multiple functions (structural support, sealing, and cable protection) into fewer integrated components. The pipe socket with integrated rubber-elastic molded part replaces the separate pipe socket, sealing compound container, and casting resin components, reducing the total number of items that need to be stored and handled.
Solution Approach 2:
The pipe socket is designed as a multi-functional component that simultaneously provides mechanical support, guides cable installation, and creates gas-tight seals through the integrated rubber-elastic molded part. This universal design eliminates the need for multiple specialized components and materials.
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
The solution simplifies installation, ensures a perfect sealing function without the need for additional sealing materials, and facilitates easy assembly with visual verification of gas-tight connections, while also providing space savings through guided deflection of lines within the duct.
Implementation Method 1
the pipe socket has a rubber-elastic molded part for splash-proof sealing of at least one cable, cable protection tube or other line routed through the wall of the building

AI summary
The feed through has a base body (3) with a pipe support (6) bent opposite to a longitudinal axis, where the support is arranged in a cylindrical wall passage opening. A bush-like connecting element is arranged in a cavity for connecting two cable ends, pipe ends or conduit ends in a gas-tight manner. A part (17) of the connecting element is fixedly connected with the base body, and the support has a rubber elastic molded part (10) for sealing cables, cable protection pipes or conduits guided through a housing wall with respect to the opening or a pipe arranged in the opening.
