Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing underground water collection and storage chamber systems face maintenance challenges due to the transfer of debris, sediments, and pollutants from primary to secondary chambers through straight pipes, leading to clogging and increased maintenance costs.
Innovation Solution
The implementation of 90° angled water transfer devices with filters or screens at the inlet to prevent coarse debris and pollutants from entering, paired with optional sediment trap mechanisms to manage sediment accumulation, and bypass systems to handle heavy flows, ensuring efficient water transfer while minimizing pollutant transfer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a straight pipe is used as a water transfer device, then water can be transferred from the primary chamber to the secondary chamber, but debris, sediments, and pollutants are also transferred, leading to clogging and increased maintenance costs
Solution Approach 1:
The patent introduces an intermediary device (the angled transfer pipe with inlet screen and sediment trap) between the primary and secondary chambers. This intermediary structure filters out debris and sediments while allowing water to pass through, preventing harmful materials from reaching the secondary chamber and reducing maintenance requirements.
Solution Approach 2:
The patent extracts the harmful components (debris, sediments, pollutants) from the water flow before transfer to the secondary chamber. The inlet screen captures coarse debris, while the sediment trap removes finer particles, effectively separating harmful materials from the water that needs to be transferred.
2Device complexity
If a straight pipe transfer device is used, then the system structure is simple, but maintenance becomes expensive and time consuming due to accumulated debris and sediment buildup
Solution Approach 1:
The sediment trap is designed to allow easy access and cleaning of accumulated sediments. The trap chamber can be opened to remove built-up debris, enabling maintenance personnel to service the system without complex disassembly or specialized equipment, thus reducing maintenance time and costs while keeping the overall structure relatively simple.
3Object-affected harmful factors
If the transfer device inlet is positioned high to prevent debris entry, then pollutant transfer is reduced, but water flow intake may be insufficient during heavy rainfall events
Solution Approach 1:
The patent applies different functional qualities to different parts of the transfer device. The inlet screen provides fine filtration for pollutants, while the angled configuration and sufficient pipe diameter ensure adequate water flow capacity. Each component is optimized for its specific function while working together to resolve the contradiction between filtration and flow capacity.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This solution reduces maintenance costs and time by minimizing debris and pollutant transfer, preventing clogging, and allowing for controlled overflow management, thus extending the system's operational lifespan.
Implementation Method 1
the entrance to the water transfer device might contain a filter or a screen for preventing course debris sediment and/or other pollutants from entering the water transfer device
Implementation Method 2
the water would rise within the primary chamber and upwards through the inlet of the water transfer device until it reaches the 90° angle of the water transfer device
