Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current water purification methods are limited by short residual action, high costs, requirement for electrical sources, and inability to effectively remove all contaminants, especially in rural or remote areas without access to electricity, and they often require complex operations and equipment.
Innovation Solution
A solid formulation comprising a flocculant, stabilizer, algaecide, chelator, disinfectant, and oxygenating agent that can be used manually or industrially to purify and disinfect water by forming flocs that are easily filtered, providing residual action and removing a wide range of contaminants, including heavy metals and organic matter, without the need for continuous chemical recharging or extensive monitoring.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If physical and chemical purification methods (boiling, reverse osmosis, filtration) are used, then water purification effectiveness is improved, but energy consumption and equipment complexity increase
Solution Approach 1:
The patent replaces mechanical purification systems (reverse osmosis membranes, UV lamps, ozone generators) with a chemical composition system. The composition contains coagulants, flocculants, and disinfectants that chemically treat water without requiring electricity or complex机械设备, making it suitable for remote areas without power supply.
Solution Approach 2:
The invention uses a disposable chemical composition that can be added directly to water containers. Instead of maintaining expensive permanent purification equipment, users simply add the composition as needed, reducing both initial investment and ongoing energy costs.
2Reliability
If complex water treatment systems with multiple chemicals are used, then purification effectiveness is improved, but operational complexity and monitoring requirements increase
Solution Approach 1:
The patent combines multiple purification functions (coagulation, flocculation, disinfection, deodorization) into a single integrated composition. This eliminates the need for operators to separately dose and monitor multiple chemicals, simplifying the treatment process while maintaining comprehensive purification effectiveness.
Solution Approach 2:
The composition is designed to perform multiple functions simultaneously: removing suspended particles, killing pathogens, eliminating odors, and preventing recontamination. This multi-functionality in a single product reduces operational complexity compared to systems requiring separate treatments for each function.
3Reliability
If strong oxidizing agents (ozone, chlorine) are used for disinfection, then microbial elimination is improved, but corrosive effects and chemical instability increase
Solution Approach 1:
The patent uses calcium hypochlorite (70% concentration) as the disinfectant, which provides strong oxidizing power for effective microbial elimination but is less corrosive than gaseous chlorine or ozone. The composition also includes stabilizers that control the release rate and reduce unwanted side effects while maintaining disinfection effectiveness.
Solution Approach 2:
The invention creates a composite composition that combines the disinfectant with coagulants, flocculants, and stabilizers. This composite approach allows the disinfectant to work synergistically with other components, reducing the need for excessive doses and thereby minimizing corrosive effects on infrastructure.
4Reliability
If conventional purification methods are used, then water treatment is achieved, but residual action is short and frequent reapplication is needed
Solution Approach 1:
The composition includes stabilizers and protective agents that create a lasting protective effect on treated water. These preliminary additions ensure that the disinfectant and other active components remain effective for extended periods, providing residual action that prevents recontamination without requiring frequent reapplication.
