Sanitary Water Supply Control for Drainage Clog Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies fail to effectively manage and control the total water volume used across multiple sanitary facility devices, leading to potential clogging in drainage systems and inefficiencies in water usage.
Innovation Solution
A control device that adjusts water supply volumes to individual sanitary facility devices based on actual and target water volumes, using indicators to prevent excess usage and manage drainage system clogging through circulation and adjustment of water volumes.

Engineering Contradiction Analysis
1Productivity
If water volume control is implemented for individual sanitary facility devices, then water usage of each device can be optimized, but the total water usage across multiple devices cannot be effectively managed
Solution Approach 1:
The patent combines multiple individual water volume control systems into a unified control device that manages water supply to multiple sanitary facility devices simultaneously. The control device integrates control functions for different devices (urinals, flush toilets, washbasins) into a single system that can collectively manage total water usage while maintaining individual device optimization.
Solution Approach 2:
The control device is designed with multi-functionality to manage various types of sanitary facility devices through a single unit. It can control water supply to different device types (urinals with different orifice diameters, flush toilets with different flush volumes, washbasins) using universal control mechanisms and water volume setting units, eliminating the need for separate control systems for each device type.
2Reliability
If water volume is increased to ensure proper flushing function, then flushing performance is maintained, but total water consumption increases and may exceed target volume
Solution Approach 1:
The patent applies local quality by providing different water volumes and control parameters tailored to each type of sanitary facility device. Urinals with different orifice diameters receive different water volumes, flush toilets have different flush volume settings, and washbasins have specific control parameters. This ensures each device receives the appropriate local water quality and quantity needed for proper function while optimizing overall water usage.
Solution Approach 2:
The control device enables parameter changes by allowing adjustment of water supply volumes, timing, and pressure parameters for different devices and different operating conditions. The water volume setting units and control mechanisms can modify flow parameters dynamically to achieve proper flushing function at optimized water consumption levels, preventing excessive water use while maintaining reliability.
