A water recirculation system intended for recycling of water or discarding of water not suitable to recycle

Solution Overview

Problem

Existing water recirculation systems lack efficiency and stability, particularly during peak power demand times and in maintaining water quality, as they often rely on a single heating source that struggles to manage varying heating demands and water quality conditions.

Innovation Solution

A water recirculation system with two heating sources, including a first heating source for base energy demand and a second heating source for peak demands, along with a sensor unit and control unit to manage water quality and direct recycling or discarding based on sensor measurements, enhancing system operation stability and efficiency.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If a single heating source is used in the water recirculation system, then the device complexity is reduced, but the system reliability and stability deteriorate during peak power demand times

Engineering Contradiction:
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

The heating system is segmented into multiple independent heating sources (first heating source and second heating source) that can operate independently or in combination. This segmentation allows the system to distribute the heating load across multiple units, improving reliability during peak demand while maintaining manageable complexity through modular architecture.

Inventive Principle:
Principle #1Segmentation

2Power

If a single heating source operates heavily during peak demand, then the heating power requirement is met, but the energy efficiency and operational stability deteriorate

Engineering Contradiction:
Core Design Contradiction:
PowerVSUse of energy by moving object

Solution Approach 1:

The system dynamically adjusts the operation of multiple heating sources based on real-time heating demands and water quality conditions. The control unit can switch between using one heating source or both heating sources depending on the situation, optimizing energy efficiency while meeting power requirements. This dynamic operation prevents any single heating source from operating continuously at heavy load.

Inventive Principle:
Principle #15Dynamics

3Power

If the heating source runs heavily to meet peak demand, then the heating power is sufficient, but the system stability and water quality maintenance deteriorate

Engineering Contradiction:
Core Design Contradiction:
PowerVSStability of the object's composition

Solution Approach 1:

The system incorporates sensors that continuously monitor water quality parameters and provide feedback to the control unit. Based on this feedback, the control unit adjusts the operation of heating sources and water recirculation to maintain optimal water quality. This closed-loop control ensures that heating power is applied appropriately to maintain water quality stability without excessive or insufficient heating.

Inventive Principle:
Principle #23Feedback

4Device complexity

If one heating source is used, then the device complexity is low, but the adaptability to varying heating demands deteriorates

Engineering Contradiction:
Core Design Contradiction:
Device complexityVSAdaptability or versatility

Solution Approach 1:

The heating system is designed with multiple heating sources that can serve different functions and operate in different modes. The first heating source and second heating source can each handle different heating scenarios, and the control unit can select the appropriate configuration based on demand. This multi-functionality increases adaptability while maintaining reasonable complexity through standardized components and control logic.

Inventive Principle:
Principle #6Universality (Multi-functionality)
