Gray Water Flush Container for Mobile Toilets Without Clogging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile toilet systems require large flush water containers due to limited access to water replenishment, leading to significant space and weight constraints, and frequent replenishment intervals, which can result in system malfunctions and customer dissatisfaction due to clogging and bacterial growth issues when using gray water as flush water.
Innovation Solution
A flush water container system that treats gray water from washbasins with descaling and bactericidal agents, preventing clogging and bacterial growth, allowing the reuse of gray water as flush water, thereby reducing the volume and weight of fresh water needed and extending replenishment intervals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the flush water container is dimensioned sufficiently large to provide the required flushing capacity, then the flushing capacity is improved, but the installation space occupied and transport weight increase
Solution Approach 1:
The patent changes the chemical parameters of the gray water by adding descaling and bactericidal agents, transforming it from unsuitable to suitable for flushing purposes. This allows the system to achieve reliable flushing capacity without needing to transport large amounts of fresh water, thereby reducing transport weight while maintaining flushing performance
2Reliability
If the flush water container is dimensioned sufficiently large to provide the required flushing capacity, then the flushing capacity is improved, but the installation space occupied increases
Solution Approach 1:
By chemically treating gray water with descaling and bactericidal agents, the patent transforms it into usable flush water. This parameter change enables the system to achieve sufficient flushing capacity with a smaller water storage container, thereby reducing installation space while maintaining reliable flushing performance
3Quantity of substance
If gray water is used as flush water without treatment, then the amount of fresh water needed is reduced, but clogging and bacterial growth occur
Solution Approach 1:
The patent introduces chemical agents (descaling and bactericidal substances) as intermediaries between the gray water and the flushing system. These agents mediate by preventing clogging and bacterial growth, allowing gray water to be used as flush water without causing system malfunctions, thus reducing fresh water consumption while maintaining system reliability
4Weight of moving object
If the water store is replenished at short intervals to reduce the amount of water transported, then the transport weight is reduced, but the operating time between replenishments is limited
Solution Approach 1:
The patent changes the usability parameters of gray water through chemical treatment, enabling its reuse as flush water. This extends the effective operating time between water replenishments by allowing the same water volume to serve multiple purposes (washbasin and toilet flushing), thereby reducing transport weight while extending operational duration
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 system significantly reduces the amount of water and space required for mobile toilet systems, prevents clogging and bacterial growth, and maintains uniform water quality over extended periods, ensuring reliable operation and customer satisfaction.
Implementation Method 1
due to chemical precipitation of calcium and magnesium salts that may be formed when using soaps in calcium-containing water
Implementation Method 2
treating the gray water by adding a descaling and/or bactericidal treatment agent
Implementation Method 3
treating the gray water by adding a descaling and/or bactericidal treatment agent
