Solution Overview
Problem
Existing drain devices for traffic jams or expulsion of media from a liquid reservoir are bulky, requiring large installation spaces and are difficult to clean and operate safely.
Innovation Solution
A compact drain device with a cover, first and second dust walls, where the first dust wall is airtight with the cover, and the second dust wall is movable relative to the cover, allowing for elastic movement and easy assembly and cleaning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional drainage device is used to prevent flooding and water damage, then the liquid reservoir is protected from overflowing, but the device becomes bulky and requires a large amount of installation space
Solution Approach 1:
The second dam wall is designed to be movable relative to the cover, transitioning between a neutral state with a defined distance from the cover and a compressed state where it contacts the cover. This dynamic structure enables the drainage device to adapt its configuration based on water level, providing overflow protection only when necessary while minimizing installation space during normal operation
Solution Approach 2:
The elastic mobility of the second dam wall allows it to change its position parameter in response to water pressure. When water level rises and contacts the dam wall, the elastic material deforms and moves the wall toward the cover, changing the volume of the first dam volume and enabling controlled drainage at a defined water height
2Volume of stationary object
If the second dam wall is made elastically movable to enable compact design, then the installation space is reduced, but the complexity of ensuring airtightness and controlled movement increases
Solution Approach 1:
The second dam wall is made of elastic material that can deform and move in response to water pressure. This flexible structure eliminates the need for complex mechanical actuators or seals, as the elastic material itself provides both the movement mechanism and the sealing function when contacting the cover
Solution Approach 2:
The elastic second dam wall automatically responds to water level changes without external control. When water contacts the dam wall, the elastic force naturally moves it toward the cover to compress the first dam volume and enable drainage, eliminating the need for external sensors, actuators, or control systems
