Direct Water Pressure Tank Flush System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional toilet flush systems are prone to fatigue, malfunctions, leaks, and water waste due to complex mechanical and hydraulic interactions, including automatic refill and shut-off mechanisms, which require precise adjustments and continuous maintenance, and are not easily retrofittable to different toilet bowl designs.
Innovation Solution
The Flush-All system uses a Direct Water Pressure Tank connected directly to city water, combining water pressure, gravity, and trapped air to provide an on-demand flushing mechanism that allows users to control the flush duration and volume, eliminating the need for predetermined water amounts and reducing mechanical interactions, with a universal mounting base for easy retrofitting to various toilet bowls.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If conventional automatic refill and shut-off mechanisms are used, then predetermined water volume is delivered, but mechanical complexity and failure risk increase
Solution Approach 1:
The patent removes the automatic refill and shut-off mechanisms from the toilet tank system. Instead of using complex mechanical components to control water delivery, the system relies on direct user activation and simple float-based level control, extracting the problematic elements that cause mechanical failures while maintaining the essential water delivery function
Solution Approach 2:
The float mechanism automatically stops water flow when the tank reaches the appropriate level without requiring additional mechanical shut-off components. The system self-regulates water level through buoyancy-based float control, eliminating the need for complex automatic refill and shut-off mechanisms that are prone to failure
2Force
If pressurized container is used, then flush force is enhanced, but pressure consistency deteriorates
Solution Approach 1:
The patent separates the water storage function from the pressurization function. The tank stores water at atmospheric pressure, and pressurization occurs only during the flush event through rapid inflow and air expansion. This segmentation allows strong flush force during operation while maintaining stable, predictable pressure characteristics through simple physical principles rather than complex pressurized containers
Solution Approach 2:
The system uses periodic action by allowing air to be trapped and compressed during water inflow, then releasing this compressed air to enhance flush force when needed. The air pocket acts as a periodic energy storage mechanism that provides consistent, predictable pressure enhancement during each flush cycle without requiring a continuously pressurized container
3Reliability
If multiple mechanical components are used, then flushing function is achieved, but maintenance requirements increase
Solution Approach 1:
The patent removes numerous mechanical components including automatic refill mechanisms, complex shut-off valves, and multiple moving parts. By extracting these elements, the system achieves reliable flushing function through simple user activation and basic float control, while dramatically reducing maintenance requirements as there are fewer components that can fail or require servicing
4Device complexity
If predetermined flush volume is used, then automatic control is simplified, but water waste increases
Solution Approach 1:
The patent makes the flush volume dynamic and user-controllable rather than fixed and predetermined. Users can adjust the flush duration and water flow rate in real-time based on actual needs, allowing the system to adapt to different situations (light vs. heavy usage) and eliminate water waste associated with fixed-volume flushes while maintaining simple control through direct user interaction

AI summary
Improvements in a toilet flush system where the flush is not determined only by a simple gravitational flow of the water tank content. The Flush-All provides a quick flush, as soon as the flush handle is released the flushing stops. There is no sticking of the flushing flapper, leaky flapper, leaky O-rings, sticky plungers, wasted water flow by improperly adjusted water level height as water continuously flows over the overfill tubing, or defects in the incoming water automatic shut off system or the noise that accompany such continuous flow. The Flush-All provides a universal design that can be used on most toilet bowls systems, a simple retrofitting procedure using a universal mounting base that is retrofitted to most existing toilet bowl. The only part to be replaced is the toilet tank. It is a quick and easy procedure that requires no structural damage or repair to the bathroom.
