Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing water treatment systems with multiple control valves for multi-stage treatment are costly, occupy large space, have high failure rates, and lack effective rinsing and backwashing capabilities, leading to contamination and reduced cleaning effectiveness.
Innovation Solution
A water treatment device with a single control valve that allows for series connection of three treatment devices, enabling separate and individual backwashing or rinsing of each device, with wastewater diversion to prevent contamination, and includes a regenerant solution for softening resin treatment without affecting other devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If multiple control valves are used for each water treatment device, then each device can be independently controlled for treatment and rinsing, but the system complexity, manufacturing cost, space occupation, and failure rate increase significantly
Solution Approach 1:
A single control valve is designed to perform multiple functions: controlling water flow for treatment, rinsing, and backwashing operations across three water treatment devices. The valve body includes multiple valve cores that can be rotated to different positions to control different flow paths, enabling one valve to replace what would traditionally require three separate valves.
Solution Approach 2:
The patent combines the control functions of three separate control valves into a single integrated control valve assembly. The valve body houses multiple valve cores that work together to control water flow to and from multiple treatment devices, merging previously separate control functions into one unified device.
2Manufacturing precision
If three filter media tanks are connected in series for multi-stage treatment, then water quality improves through sequential treatment, but rinsing effectiveness deteriorates because wastewater from one tank contaminates the next
Solution Approach 1:
The control valve is designed with separate control paths for each water treatment device, allowing independent rinsing operations. When rinsing one tank, the valve configuration ensures that rinse water and wastewater are directed through dedicated paths that do not intersect with other tanks, preventing cross-contamination while maintaining the series connection for treatment.
Solution Approach 2:
The control valve acts as an intermediary that manages water flow between the three treatment devices and the external environment. Through its multiple valve cores and flow passages, it mediates the rinsing process by directing rinse water to the target tank and routing wastewater to discharge, preventing direct communication between tanks during rinsing operations.
3Device complexity
If a single control valve is used to control multiple water treatment devices, then system complexity and cost are reduced, but the ability to perform separate backwashing and rinsing operations on each device is lost
Solution Approach 1:
The control valve incorporates multiple valve cores that can be rotated independently to different positions, dynamically changing the flow paths. This rotational mechanism allows the single valve to adapt its configuration for different operations: treatment mode, rinsing mode, backwashing mode, or combinations thereof, providing the versatility previously requiring multiple valves.
Solution Approach 2:
The control valve is segmented into multiple independent valve cores within a single valve body, each capable of controlling specific flow paths. This segmentation allows independent control of treatment and rinsing functions for each water treatment device, even though all functions are housed within one valve assembly.
