Plumbing Trap Flushing Device Nozzle Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing plumbing trap flushing devices often rely on pressure build-up, which can damage pipes and are prone to nozzle entanglement, and they do not effectively deliver water directly to the clog, leading to limited success in unclogging drains.
Innovation Solution
A plumbing trap flushing device with a connector attachable to a tap, a conduit with a nozzle that produces a water jet to dislodge clogs without relying on pressure build-up, featuring a design where the conduit's outside diameter fits into the drain, allowing liquid and air to flow freely, and the nozzle's smaller diameter increases water pressure for effective clog removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If pressure build-up is used to force clogs through the drain, then the clog can be dislodged, but the pressure exceeds allowable limits and degrades the pipe
Solution Approach 1:
Instead of building pressure behind the clog to force it through (conventional approach), this invention inverts the approach by using a high-velocity water jet that travels down the drain and breaks up the clog from the front. The nozzle directs water flow in the same direction as the desired clog movement, eliminating the need for excessive pressure build-up that damages pipes.
Solution Approach 2:
This invention applies hydraulic principles by using a focused high-velocity water jet to dislodge and break up clogs. The nozzle converts water pressure into a concentrated stream that delivers sufficient force to break apart debris without requiring the entire trap system to be pressurized to damaging levels.
2Productivity
If complex nozzles are used to deliver water, then water can be directed to the clog, but the nozzles are prone to catching on drains when inserted and removed
Solution Approach 1:
The nozzle is designed with a simplified geometry that has smooth surfaces and appropriate diameter to match the drain opening. This local design optimization ensures the nozzle can be easily inserted and removed without catching on drain components, while still maintaining effective water delivery capability through proper nozzle hole configuration.
3Ease of operation
If nozzles only fit into the top of the trap, then the device is easier to use, but water is not delivered directly to the clog
Solution Approach 1:
The nozzle is designed to extend beyond the trap opening in a dimensional extension that allows it to reach down and contact the clog directly. This dimensional adjustment enables the nozzle to deliver water precisely where needed (at the clog location) while maintaining easy access for insertion and removal operations.
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 device effectively breaks up and removes clogs without damaging pipes, as the water jet dislodges debris without excessive pressure, ensuring efficient unclogging and minimizing pipe degradation.
Implementation Method 1
The nozzle has a nozzle inside diameter less than the inside diameter of the conduit whereby the water exits the nozzle in a stream

AI summary
A plumbing trap flushing device for use in association with one of a drain in a sink, an overflow drain in a basin, a drain in a bathtub, an overflow drain in a bathtub and the like is disclosed. The plumbing trap flushing device includes a connector, a conduit and a nozzle. The connector is releasably attachable to a tap. The conduit is in flow communication with the connector and has an outside diameter and an inside diameter. The outside diameter is dimensioned to fit into the drain, whereby when the conduit is in the drain air and water freely flows around the conduit into the drain. The nozzle is in flow communication with the distal end of the conduit. The nozzle has a nozzle inside diameter less than the inside diameter of the conduit whereby the water exits the nozzle in a stream.
