Anti-Urine Splattering System for Toilets
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Sanitary plumbing fixtures, such as toilets and urinals, face the issue of urine splashing out during urination, which is not effectively addressed by existing technologies.
Innovation Solution
An anti-urine splattering system comprising a sanitary plumbing fixture, a spray head, a first valve, an electronic controller, and a supplemental water tank, where the spray head creates a water curtain across the fixture's aperture to prevent splashed urine from exiting, initiated by the electronic controller actuating the first valve, and optionally supplemented with water from a separate tank.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a water curtain is created using the existing flush water system, then urine splashing is prevented, but the flushing water volume is reduced compromising toilet performance
Solution Approach 1:
The water supply system is segmented into two independent sources: the existing flush water system and a supplemental water tank. The spray head receives water from both sources through separate valve controls, allowing the water curtain function to be separated from the flushing function, thus preventing urine splashing without compromising flush water volume
Solution Approach 2:
A supplemental water tank acts as an intermediary water source specifically for generating the water curtain. This separate water reservoir provides the anti-splashing function independently, so the main flush water system remains unaffected and retains full flushing capability
2Object-affected harmful factors
If a separate supplemental water tank is added to provide water for the water curtain, then sufficient water is available for preventing splashing, but the device complexity increases
Solution Approach 1:
The supplemental water tank serves multiple functions: it provides water for the water curtain spray head, and can potentially supply water for other fixture functions. The dual-valve system allows the same tank to serve different purposes, reducing the need for additional separate water sources and minimizing overall system complexity
Solution Approach 2:
The control systems for the spray head and flush valve are merged into a coordinated electronic control system that manages both water sources efficiently. The controller integrates the operation of the first valve (controlling flush water to spray head) and second valve (controlling supplemental water to spray head), simplifying the overall control architecture despite adding hardware components
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
Effectively prevents urine splashing by creating a water curtain that deflects urine back into the fixture, enhancing hygiene and cleanliness during use.
Implementation Method 1
The spray head may be operable to create a water curtain across an aperture of the sanitary plumbing fixture. The water curtain may prevent splashed urine from exiting the sanitary plumbing fixture during urination.

AI summary
The anti-urine splattering system for toilets and urinals comprises a sanitary plumbing fixture, a spray head, a first valve, an electronic controller, and an activation control. The spray head may be operable to create a water curtain across an aperture of the sanitary plumbing fixture. The water curtain may prevent splashed urine from exiting the sanitary plumbing fixture during urination. The electronic controller may initiate the water curtain responsive to input from the activation control. The electronic controller may initiate the water curtain by electrically actuating the first valve. In some embodiments, the spray head may be supplied with water from a supplemental water tank via a second valve. As non-limiting examples, the sanitary plumbing fixture may be a toilet or a urinal.
