Building-Surrounding Channel Drain With Sliding Barriers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing storm water devices do not effectively capture and redirect water away from buildings using a channel drain that surrounds the building, and lack barriers integrated into the channel drain to route water into an overflow reservoir.
Innovation Solution
A channel drain installed around a building with slidably integrated barriers that deflect storm water into the drain, paired with pipes to direct water into a municipal drain or overflow reservoir, and a sump pump to manage overflow.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a channel drain is installed to surround a building for capturing storm water, then the building is protected from storm water runoff, but the device complexity increases due to the need for multiple barriers and integrated piping systems
Solution Approach 1:
The channel drain system is divided into multiple functional segments including barriers for water redirection, primary drain pipes for standard drainage, and secondary overflow pipes for extreme conditions. Each segment performs a specific function, allowing the system to handle various storm water scenarios effectively while maintaining manageable complexity through modular design
Solution Approach 2:
The overflow drain pipe is positioned within the same channel drain structure as the primary drain pipe, with the overflow pipe located above it. The barriers are integrated into the channel drain, creating a nested configuration where multiple drainage functions are contained within a single unified structure, reducing overall system complexity
2Productivity
If barriers are slidably integrated into the channel drain to deflect storm water, then water redirection efficiency is improved, but the manufacturing complexity increases
Solution Approach 1:
The barriers are designed to be slidable within the channel drain, allowing them to move between a stored position during normal conditions and a deployed position during storm events. This dynamic capability enables efficient water redirection only when needed, while simplifying manufacturing by using standard sliding mechanisms rather than complex fixed structures
Solution Approach 2:
The barriers serve multiple functions: they deflect storm water into the channel drain, can be positioned at different locations along the drain, and work in conjunction with both the primary and overflow drain pipes. This multi-functionality is achieved through a single standardized barrier design that can be manufactured once and deployed in various positions
3Reliability
If an overflow reservoir is added to handle excessive storm water, then the system reliability under severe conditions is improved, but the loss of substance increases due to temporary water storage
Solution Approach 1:
The overflow reservoir is positioned to receive excess storm water before it can cause flooding or damage to the building. By providing this预先 storage capacity, the system can handle severe storm conditions that exceed the primary drainage capacity, then gradually release the stored water when the storm subsides, preventing water loss through flooding
4Reliability
If dual drain pipes are installed (one for primary drainage and one for overflow), then the drainage reliability is improved, but the device complexity and manufacturing cost increase
Solution Approach 1:
The overflow drain pipe is positioned vertically above the primary drain pipe within the same channel drain structure. This vertical arrangement in the third dimension allows both drainage functions to coexist in a compact space, maintaining reliability through dual drainage paths while minimizing horizontal space requirements and simplifying the overall piping layout

AI summary
A storm water redirection device includes a channel drain installed in the ground to completely surround a building to capture storm water. A plurality of barriers is each slidably integrated into the channel drain. Each of the plurality of barriers is positionable in a deployed position to deflect the storm water into the channel drain for collecting the storm water. A first drain pipe is positioned in a respective intersecting section of the channel drain to drain the storm water from the respective channel drain. A second drain pipe is positioned above the first drain pipe to drain the storm water from the channel drain when the storm water is filling the channel drain faster than the first drain pipe can drain the storm water from the channel drain. An overflow reservoir is buried beneath the ground to contain the storm water that drains through the second drain pipe.
