French Drain Pipe with Integrated Flushing Orifices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
French drain systems often clog due to the accumulation of iron ocher, a gelatinous deposit from iron oxidation in groundwater, which can lead to under-performance or failure of the drainage system.
Innovation Solution
A perforated pipe design with integrated conduits and orifices that allow for the introduction of wash fluid to flush out iron ocher from the pipe and surrounding gravel, using pressurized water to effectively remove the deposit without the need for external conduits.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional perforated pipe is used in a French drain system, then the drainage system can collect and redirect water, but iron ocher accumulates in the pipe and perforations causing clogging and system failure over time
Solution Approach 1:
The patent incorporates cleaning orifices and conduit structures during the initial pipe installation that enable future flushing operations. These features are built into the pipe design beforehand, allowing iron ocher to be flushed out through the cleaning orifices using high-pressure water or air, preventing clogging before it occurs.
Solution Approach 2:
The patent introduces a cleaning fluid (water or air) as an intermediary substance that flows through the conduit and exits via cleaning orifices to remove iron ocher deposits. This intermediary medium facilitates the removal of harmful accumulations without requiring direct mechanical intervention.
2Ease of repair
If external conduits are added to flush iron ocher from the drainpipe, then iron ocher removal is enabled, but device complexity increases
Solution Approach 1:
The patent merges the cleaning function with the existing drainpipe structure by integrating cleaning orifices directly into the pipe wall and using the pipe's internal conduit space for flushing operations. This consolidation eliminates the need for separate external conduits while maintaining the iron ocher removal capability.
Solution Approach 2:
The patent designs the conduit to serve dual purposes: transporting drainage water during normal operation and serving as a flushing pathway for removing iron ocher deposits. This multi-functionality reduces the need for additional dedicated cleaning infrastructure.
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 enables efficient removal of iron ocher from both the pipe and gravel, maintaining the drainage system's performance and preventing clogging, while being practical and accessible for regular maintenance.
Implementation Method 1
a first wash fluid is receivable at the first conduit and dischargeable through the at least one first orifice into the third conduit and a second wash fluid is receivable at one or more second conduit of the pair of second conduits and dischargeable through the at least one second orifice to the outside environment before entering the third conduit through the at least one third orifice

AI summary
A French drain drainpipe with built-in means for flushing iron ocher out of the drainpipe, out of the perforations, and out of the gravel surrounding the drainpipe. Said means may include chambers for receiving pressurized washing fluids and exit orifices from the chambers. Fittings are provided for connecting the chambers to a pressurized source of washing fluids, such as hose fittings for connecting to a normal household water supply.
