Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fluid flow control systems, particularly in irrigation and similar applications, face challenges with manual valve adjustments for varying conditions and lack of functionality without electrical power, leading to inefficient water usage and potential for rapid cycling.
Innovation Solution
A system that uses a container with a valve actuated by a liquid level, employing a piston and magnet mechanism or float, to control fluid flow based on liquid levels within the container, allowing automatic adjustment of flow rates and operation without electricity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If manual valve control is used to adjust fluid delivery for varying circumstances, then the system can adapt to different conditions, but it becomes time-consuming and burdensome
Solution Approach 1:
The valve system automatically adjusts fluid delivery based on liquid level in the container without requiring manual intervention. The float mechanism self-regulates the valve opening and closing based on predetermined levels, eliminating the need for time-consuming manual adjustments while maintaining adaptability to varying conditions.
Solution Approach 2:
The system incorporates a float that provides continuous feedback on the liquid level to the valve mechanism. When the liquid level changes, the float moves accordingly and automatically signals the valve to adjust its position, creating a closed-loop feedback system that adapts to varying conditions without manual input.
2Extent of automation
If electrically controlled valves are used to automate fluid delivery, then manual intervention is reduced, but the system becomes unusable without electrical power
Solution Approach 1:
The invention replaces electrical control mechanisms with a purely mechanical float-actuated valve system. The float moves with liquid level changes and mechanically opens or closes the valve through linkages, eliminating dependence on electrical power while maintaining automatic control functionality.
Solution Approach 2:
The mechanical valve system is self-actuating through the float mechanism that responds automatically to liquid level changes. No external power source is required as the system uses the potential energy of the floating mechanism to control valve operation, ensuring reliability in locations without electrical infrastructure.
3Device complexity
If single-level valve control is used, then the system is simple, but it causes rapid cycling and uncontrollable operation
Solution Approach 1:
The control system is segmented into multiple discrete levels using separate floats for high-level and low-level control. Each float operates independently at its designated level, preventing rapid cycling by ensuring the valve remains closed between levels and only opens when the liquid drops to the low level, providing stable and predictable operation.
