Floor Feed-Through Bushing With Integrated Drain Channel
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
During the installation of feedthroughs in walls or floors, water accumulation in protective pipes outside buildings, particularly in hilly terrain, can lead to uncontrolled water entry into the building when the pipes are removed, posing safety risks and requiring a solution for controlled drainage.
Innovation Solution
The implementation of a bushing with a closure that seals the pipe element and a drain channel with a smaller cross-section than the tubular element, allowing for controlled drainage of water through a drain hose, which is connected to the drain channel and directed outside or to a drain, using a drain unit that opens the blind closure by inserting a pin to facilitate water flow.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the protective pipe is removed without draining water, then the installation process is simpler and faster, but water enters the building uncontrolled causing safety risks
Solution Approach 1:
The drain channel is pre-integrated into the bushing structure during manufacturing, allowing water to be drained before pipe removal. This preliminary drainage action eliminates the safety hazard of uncontrolled water entry while maintaining installation efficiency, as the drainage pathway is already in place and requires no additional complex setup.
Solution Approach 2:
The drain channel acts as an intermediary structure between the protective pipe and the building interior. It provides a controlled intermediate pathway for water to exit the protective pipe gradually, mediating between the stored water in the pipe and the building interior, thus preventing direct uncontrolled water entry.
2Productivity
If a drain channel with large cross-section is used, then water drainage is faster, but the force required for insertion increases
Solution Approach 1:
The drain channel's cross-sectional area is optimized to a specific range (1-10 cm²) that balances drainage performance with insertion feasibility. This parameter optimization ensures that the channel is large enough to drain water effectively but small enough to be inserted with acceptable force, resolving the contradiction between drainage speed and insertion effort.
3Force
If the drain channel has small cross-section, then insertion force is reduced, but drainage capacity is limited
Solution Approach 1:
The drain channel cross-sectional area is set within the optimal range of 1-10 cm², which represents a carefully balanced parameter choice. This parameter optimization ensures sufficient drainage capacity for typical water accumulation scenarios while maintaining insertion forces at acceptable levels, resolving the trade-off between drainage capacity and insertion effort.

Function Achieved in This Case
This solution enables safe and controlled drainage of water, preventing uncontrolled water entry into the building and reducing the force required for insertion, thus ensuring safer and more efficient installation of cables and lines by allowing water to be drained before pipe removal.
Implementation Method 1
The bushing has a closure that closes the pipe element in relation to its longitudinal direction, i.e. seals it (prevents the passage of water within the scope of what is technically usual)
Implementation Method 2
Through this drain channel, any water that has collected in the pipe element on one side of the closure can advantageously be drained from the other side
