Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional toilets require excessive water for a single flush cycle, leading to wastefulness and inefficiency in water usage, as they fail to produce sufficient fluid velocity to properly clean the toilet bowl despite using large volumes of water.
Innovation Solution
A manifold system with moveable pistons and adjustable flow regulators, combined with a venturi tube flush valve, is introduced to control the volume and velocity of water flowing into the toilet bowl, optimizing water usage by ensuring effective cleaning with reduced water amounts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If traditional toilets use large volumes of water for flushing, then the water volume is sufficient to fill the bowl, but the water velocity is insufficient to properly clean the toilet bowl
Solution Approach 1:
The patent employs hydraulic principles by using water pressure and flow dynamics to generate high-velocity jets through specially designed nozzles and passages. The system utilizes the kinetic energy of flowing water to create effective cleaning action, transforming the bulk water flow into concentrated high-speed streams that can properly flush the bowl with reduced water volume.
Solution Approach 2:
The invention changes the flow parameters of water by using restrictors, nozzles, and variable geometry passages to convert low-velocity bulk flow into high-velocity jets. By controlling pressure, flow rate, and passage cross-section, the system optimizes water velocity while reducing overall water consumption, directly addressing the contradiction between volume and velocity.
2Loss of substance
If the amount of water used for flushing is reduced, then water wastefulness is decreased, but the force required to flush contents of the toilet bowl is insufficient
Solution Approach 1:
The system changes water flow parameters by using pressure regulators, flow restrictors, and variable cross-section passages to concentrate water flow into high-velocity jets. This transformation maintains or increases flushing force while reducing total water volume, thereby reducing water wastefulness without sacrificing cleaning effectiveness.
Solution Approach 2:
Instead of distributing water uniformly across the bowl, the invention concentrates water flow into specific high-velocity jets at critical locations. This localized concentration of kinetic energy provides sufficient flushing force with minimal water volume, reducing overall water consumption while maintaining effective flushing action.
3Quantity of substance
If traditional toilet mechanics are adjusted to reduce water usage, then water consumption is decreased, but the fundamental requirement for large water volume to generate flushing force remains unchanged
Solution Approach 1:
The invention introduces hydraulic components including pressure-regulated valves, flow restrictors, and jet-nozzle assemblies into the toilet system. These components fundamentally change how water is delivered by using fluid dynamics to generate high-velocity flows, enabling effective flushing with reduced water volume without requiring complex mechanical adjustments to the basic flush mechanism.

AI summary
Hydraulic devices used to control timing, direction, and velocity of fluid flow are disclosed. The hydraulic device includes a flush valve. The flush valve includes one or more venturi that assist in moving the fluid through flush valve. A manifold includes a housing defining a piston cavity and a piston. The piston is moveable within the piston cavity by a piston actuator between a first position and a second position. A manifold inlet defined by the housing is configured to receive a first fluid from a supply line and is in fluid communication with the piston cavity. A manifold outlet is defined by the housing and is in fluid communication with the piston cavity in. In the first position, the piston prevents fluid communication between the manifold inlet and the manifold outlet through the piston cavity. In the second position, the manifold inlet is in fluid communication with the manifold outlet such that the first fluid can flow from the supply line to the manifold outlet through the piston cavity.
