Cleaning Head Water Return Valve to Prevent Clean Water Waste
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cleaning devices waste clean water when not in use and lack efficient reclamation methods, leading to inefficiency and increased labor for users.
Innovation Solution
Incorporation of a one-way water hydraulic control valve and outlet control switch that allows clean water to flow back into the tank when not in use, utilizing pressure differences to manage water flow and prevent waste.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the water pump continues pumping water when the cleaning process is interrupted, then the water supply is maintained, but clean water is wasted by flowing directly out from the clean water outlet
Solution Approach 1:
A one-way water hydraulic control valve is introduced as an intermediary component between the outlet pipe and the clean water tank. This valve mediates the water flow by allowing clean water to flow backward into the tank through the valve when the outlet is closed, preventing direct waste while maintaining system pressure through the hydraulic action of the valve mechanism
Solution Approach 2:
The system recovers clean water that would otherwise be discarded by using the one-way water hydraulic control valve to redirect excess water back into the clean water tank. This recovery mechanism ensures that water is not lost during temporary interruptions, addressing both the waste problem and maintaining water availability for resumption
2Loss of substance
If an outlet control switch is added to prevent clean water from flowing out when not in use, then water waste is reduced, but the clean water is pumped into the waste water pipe and enters the waste water tank
Solution Approach 1:
The system uses hydraulic principles through the one-way water hydraulic control valve to automatically manage water flow based on pressure differences. When the outlet control switch closes, the hydraulic valve utilizes water pressure to redirect flow back into the clean water tank, eliminating the need for additional complex control mechanisms while preventing water waste
Solution Approach 2:
The one-way water hydraulic control valve enables the system to self-regulate water flow automatically based on pressure conditions without requiring external control signals. The valve responds autonomously to pressure changes, directing water back into the tank when needed, thereby simplifying the overall control system while preventing waste
