Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current flap and flush gates in drainage systems are prone to wear and tear due to weather conditions and fluid contact, leading to inefficiency and complicating maintenance and repair processes, as they cannot be easily stopped or replaced without extensive measures.
Innovation Solution
A drainage system comprising a reservoir with a flap gate and outlet pipes, where the system includes gate valves and ejectors to manage water pressure and flow, allowing for efficient installation, maintenance, and repair by accumulating water for pressure and using it to clear clogs and maintain gate functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If flap gates and flush gates are used to control water flow and prevent backflow, then the drainage system can automatically open and close based on differential pressure, but the gates become worn out due to weather conditions and fluid contact, leading to inefficiency and complicated maintenance
Solution Approach 1:
The system divides the gate structure into separable components: a removable closure element that can be detached from the outlet pipe. This segmentation allows the closure element to be easily removed and replaced without affecting the entire drainage system, thereby maintaining reliability while preserving automatic operation capabilities.
Solution Approach 2:
The patent introduces a retention mechanism as an intermediary component that holds the closure element in place during operation but allows for easy removal. This intermediary structure mediates between the need for reliable automatic operation and the need for easy maintenance, enabling workers to remove and replace closure elements without extensive measures.
2Productivity
If traditional flap gates are used to prevent backflow, then water flow can be controlled automatically, but the gates cannot be easily stopped or replaced without expensive and massive measures
Solution Approach 1:
The closure element is designed as a separate, removable component from the outlet pipe structure. This segmentation enables maintenance workers to access, remove, and replace the closure element directly without needing to dismantle complex retaining structures or take extensive maintenance measures, thereby improving productivity while reducing device complexity.
Solution Approach 2:
The closure element can be completely extracted or removed from the outlet pipe for maintenance or replacement. This extraction capability allows workers to service the gate component independently without affecting the rest of the drainage system, significantly improving maintenance efficiency and reducing the complexity of maintenance procedures.
3Adaptability or versatility
If the outlet pipe is under water, then the drainage system can function during flooding conditions, but the gates are exposed to constant water contact and weather conditions that accelerate wear and tear
Solution Approach 1:
The closure element is designed as a replaceable component with a shorter service life, intended to be periodically removed and replaced rather than maintained indefinitely. This approach acknowledges that components exposed to constant water and weather contact will wear out, but by making them easily replaceable, the overall system remains adaptable to flooding conditions while managing the limited lifespan of exposed components.
Solution Approach 2:
The system enables easy discarding of worn closure elements and replacement with new ones. The simple removal and replacement mechanism allows rapid replacement of degraded components without extensive maintenance measures, thereby managing the reduced lifespan caused by environmental exposure while maintaining system adaptability to flooding conditions.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system enables efficient installation, maintenance, and repair of drainage systems by utilizing water pressure to clear clogs and maintain gate functionality, reducing the need for extensive measures and ensuring effective water management.
Implementation Method 1
The water in the reservoir provides a pressure, which ensures a high water pressure through the outlet pipes
Implementation Method 2
The water pressure thought the outlet pipes is used to keep the outlet piping system clear such that the outlet piping system do not clogged
