Household Water Treatment System with Filter Performance Estimation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current water supply and sewerage systems face challenges in coping with sudden population changes and are unsuitable for areas with limited water resources, requiring large-scale construction and maintenance, and are inefficient in treating wastewater.
Innovation Solution
A household water treatment apparatus management system that includes a filter information storage unit, an information receiver for performance change data, and a water type estimation module, which uses reference information to accurately estimate water types and provide filter replacement and operation guidance, allowing for efficient wastewater treatment and water reuse without large-scale construction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If large-scale water supply and sewerage systems are constructed, then water supply coverage is improved, but construction cost and maintenance complexity increase significantly
Solution Approach 1:
The patent segments the centralized water supply system into distributed household-level treatment units. Each household apparatus independently treats water using filtration membranes and treatment chambers, eliminating the need for extensive pipe networks and centralized treatment facilities while maintaining water supply coverage.
Solution Approach 2:
The household water treatment apparatus performs self-service by automatically filtering and treating water at the point of use. The system monitors its own operation, tracks filter performance, and manages water treatment without requiring external infrastructure or manual intervention, reducing maintenance complexity.
2Reliability
If traditional water supply systems are used, then infrastructure is established, but efficiency in treating wastewater and adapting to population changes decreases
Solution Approach 1:
The system incorporates feedback mechanisms where sensors monitor water quality, flow rates, and filter performance in real-time. This data feeds back to the control unit, which adjusts treatment parameters and predicts maintenance needs, optimizing wastewater treatment efficiency and enabling rapid adaptation to changing usage patterns.
Solution Approach 2:
The household treatment apparatus dynamically adjusts its operation based on real-time conditions. The system can modify filtration rates, switch between treatment modes, and adapt to varying water quality inputs, thereby improving productivity and responsiveness compared to static traditional infrastructure.
3Quantity of substance
If centralized water treatment is implemented, then water supply is provided, but the system is unsuitable for areas with limited water resources
Solution Approach 1:
The patent implements local quality control by treating water at the household level rather than through centralized processing. This allows each unit to optimize treatment for its specific water source and usage patterns, making the system highly adaptable to areas with limited or variable water resources while ensuring adequate supply.

AI summary
A water treatment apparatus management system which manages a household water treatment apparatus located at or near a place of water use, and treats water before treatment with at least one type of filter to produce treated water for the place of water use. The system includes: a filter information storage unit storing information regarding an in-service filter used in the household water treatment apparatus; an information receiver receiving information regarding performance change of the in-service filter from the household water treatment apparatus; and a water type estimation means that estimates a water type of the water before treatment based on the information regarding performance change and the information regarding the in-service filter. The information regarding the in-service filter includes reference information of performance change of the same or the same type of filter as the in-service filter for each of plural types of reference water before treatment.
