Portable Bedside Urinal With Automatic Flush and Waste Separation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing portable urinals lack an efficient and easy-to-use automatic flushing mechanism and means for cleaning and disposing of waste water.
Innovation Solution
A portable urinal with an automatic electric water pump that flushes the funnel and waste water tube, utilizing a flexible clean water tube connected to a cylindrical container with a middle reservoir for clean water and a lower reservoir for waste water, featuring a spring-actuated valve and a 15-second automatic flush mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If a manual water pump with switch buttons is used, then the device can be operated portably, but the operation requires manual intervention and is not automatic
Solution Approach 1:
The urinal system performs automatic cleaning and flushing operations without requiring manual pump operation. The system uses the natural flow of urine and water to activate cleaning mechanisms, eliminating the need for user intervention with pump buttons while maintaining portable operation.
Solution Approach 2:
The patent replaces manual mechanical pump operation with an automatic system that uses water flow dynamics and gravity to activate cleaning functions. The system substitutes manual button-actuated pumping with automated water-driven mechanisms that perform cleaning without user input.
2Productivity
If a water sprayer is used to disinfect reservoirs, then cleaning can be performed, but water is wasted and the mechanism is inefficient
Solution Approach 1:
The system recovers and reuses water that would otherwise be wasted during cleaning operations. The flushing water and cleaning water are captured and reused in subsequent cleaning cycles, significantly reducing water consumption while maintaining effective cleaning of the urinal components.
Solution Approach 2:
The cleaning system operates continuously by using the natural flow of urine and water to activate cleaning mechanisms without interruption. The system maintains continuous cleaning action through overlapping flush and clean cycles, improving productivity while minimizing water waste through efficient water utilization.
3Ease of operation
If waste water is not properly disposed of, then the device remains simple, but hygiene and user convenience are compromised
Solution Approach 1:
The system extracts and separates waste water from the cleaning and flushing processes. A dedicated waste water reservoir and drainage mechanism are provided to collect and dispose of waste water separately from the clean water supply, simplifying the disposal process while maintaining hygiene standards.
Solution Approach 2:
The urinal system is divided into separate functional sections: a clean water reservoir, a waste water reservoir, and a drainage system. This segmentation allows for independent management of clean water supply and waste water disposal, improving ease of operation while keeping the overall system organized and maintainable.
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
Enables efficient and automatic cleaning and disposal of waste water, enhancing user convenience and hygiene.
Implementation Method 1
An electric water pump is located inside the lower part of middle clean water section 2
Implementation Method 2
A spring actuated valve 9 allows waste water to flow through to the waste water collecting tank 3
Implementation Method 3
The pump is connected to the lower part of funnel 7 by flexible and expandable clean water tube 15
Implementation Method 4
The lower end of funnel 7 rests on a circular hole in the top of the filler section 1. The funnel 7 is also fluidly connected to the upper end of the clean water tube 15

AI summary
This portable bedside urinal allows a user to urinate without walking to the bathroom. An upper, top filling section, a middle clean water reservoir, and a lower bottom waste water reservoir are generally cylindrical and stacked on one another to form the outer container. An upper funnel rests on the top of the shell container and is connected to an expandable and flexible waste water tube. Waste water runs down the funnel and waste water tube and is deposited in the lower waste water reservoir. A water pump is used for cleaning and flushing the device after use and is also located within the container The pump has a flexible and expandable clean water tube connected to both the pump and the upper funnel. After use, the pump circulates clean water to the funnel to flush the device. Using the device is simple.
