Mid-Layer Rainwater Intake Switching for Cleaner Storage Pool Water
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing rainwater regulation and storage systems face issues with the intake of water containing floating debris and sediment, leading to compromised water quality and inefficient manual cleaning processes, and lack self-check and reset functions for water intake devices.
Innovation Solution
An intelligent rainwater regulation and storage system with a toggle assembly that automatically switches between clean and sewage pipes based on water level, ensuring quality by closing the clean water pipe when the inlet is below the lower limit, and using a wedge body for self-checking and resetting to prevent sewage entry into the clean water pipe.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If mid-layer water intake is used to improve water quality, then water purity is improved, but the system complexity increases due to additional control mechanisms
Solution Approach 1:
The system uses a float ball and lever mechanism that automatically detects water level and switches pipes without external control. The float ball rises and falls with water level, mechanically actuating the lever to open/close clean and sewage pipes, making the system self-regulating and eliminating complex electronic controls
Solution Approach 2:
The lever acts as an intermediary mechanical component that translates the vertical motion of the float ball into the horizontal motion needed to switch between clean water pipe and sewage pipe. This simple mechanical intermediary resolves the complexity by using basic mechanical leverage rather than complex control systems
2Productivity
If automatic water level control is implemented, then operational efficiency is improved, but device complexity increases due to additional components
Solution Approach 1:
The system automatically monitors water level via the float ball and self-adjusts by switching between clean and sewage pipes based on the water level position, eliminating the need for manual intervention and maintaining high operational efficiency with minimal components
Solution Approach 2:
The system dynamically adapts to changing water levels by allowing the float ball to move freely with the water level, which automatically actuates the lever to switch pipes as needed, providing continuous automatic control without fixed mechanical constraints
3Productivity
If clean water pipe is kept open for water intake, then water intake efficiency is improved, but water contamination risk increases from sewage entry
Solution Approach 1:
The system preemptively closes the clean water pipe using the lever mechanism when the float ball detects low water level or potential contamination conditions, preventing sewage from entering the clean water pipe before contamination can occur, thus maintaining water quality safety
Solution Approach 2:
The float ball provides continuous feedback on water level position to the lever mechanism, which automatically adjusts pipe openings in real-time. When water level drops or contamination is detected, the feedback loop triggers the lever to close the clean water pipe and open the sewage pipe, ensuring water quality safety while maintaining intake efficiency
