Concrete Feedthrough With Double Coupling Pieces
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for routing multiple lines through concrete-cast wall or floor elements become laborious and unstable, especially with a large number of lines, as the sealing process requires threading lines through multiple passage openings in an elastomer body, often necessitating two installers for compression and insertion.
Innovation Solution
The integration of double coupling pieces into the bushing, which connect line pieces from opposite sides of the wall or floor element, allowing for easier routing and sealing of lines without the need for complex elastomer body compression, using plug-in fittings with a locking mechanism to secure the lines and prevent accidental disconnection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a press seal with multiple passage openings is used to route lines through a concrete-cast wall element, then the lines can be sealed and routed through the wall, but the installation becomes laborious and requires two installers when the number of lines increases
Solution Approach 1:
The invention divides the wall element into separate sections, each with its own bushing and sealing arrangement. Instead of one large press seal handling multiple lines, multiple smaller bushings are distributed throughout the wall thickness, allowing lines to be sealed and routed in smaller, more manageable groups, thereby reducing installation complexity while maintaining sealing reliability
Solution Approach 2:
The invention introduces bushings as intermediary components that extend through the wall thickness and provide integrated sealing and routing functions. These bushings act as mediators between the concrete wall and the lines, eliminating the need for complex press seal assemblies and manual threading operations, thus improving installation ease while maintaining reliable sealing
2Reliability
If an elastomer body with multiple passage openings is compressed to seal against lines, then sealing is achieved, but the elastomer body becomes unstable when it needs to be opened for line insertion
Solution Approach 1:
The invention replaces the single elastomer body with multiple separate bushings, each containing its own sealing mechanism. This segmentation allows each bushing to maintain structural stability independently while providing reliable sealing for individual lines, eliminating the instability issue that arises when a large elastomer body must be opened for line insertion
Solution Approach 2:
The bushings are pre-installed in the wall element during concrete casting, with sealing surfaces already positioned and prepared. This preliminary action eliminates the need to open and manipulate a large elastomer body later, maintaining both stability and sealing reliability throughout the installation process
3Productivity
If double coupling pieces are integrated into the bushing, then line routing becomes easier and labor requirements are reduced, but the device complexity increases
Solution Approach 1:
The invention merges the bushing structure with integrated double coupling pieces into a single unified component. This combination allows lines to be routed through the wall element and connected on both sides simultaneously, eliminating the need for separate coupling operations and reducing labor requirements, while the integrated design manages device complexity through functional consolidation

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This solution simplifies the installation and sealing process, allowing for efficient routing of multiple lines through the bushing, reducing labor requirements and enhancing stability by using symmetric double coupling pieces with plug-in fittings that secure lines effectively, while also protecting the components from mechanical damage.
