Multi-Tier Drainage Channels with Identical Nominal Width
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing drainage systems for traffic areas face logistical challenges due to differences in construction and function between upper and lower channels, requiring careful distinction during assembly, storage, and transport, and suffer from high production costs due to the need for wider channel covers to handle heavy loads and increased absorption capacity, which can lead to instability and clogging.
Innovation Solution
A drainage system with drainage channels of the same nominal width arranged one above the other, hydraulically connected through openings in the channel bottom, featuring identical channel bodies and frames for cost-effective production and enhanced stability, allowing for increased absorption capacity and rigidity, and enabling flexible gradient adjustments through a cascade arrangement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If wider channel covers are used to handle heavy loads and increased absorption capacity, then the absorption capacity and load-bearing capacity are improved, but the production costs and weight increase
Solution Approach 1:
The drainage system is divided into multiple identical channel bodies stacked vertically, each contributing to the total absorption capacity. This segmentation allows the system to achieve higher absorption capacity without requiring a single oversized channel cover, thereby reducing the weight and cost of individual covers while maintaining overall system performance.
2Quantity of substance
If multiple different channel bodies are used to achieve higher absorption capacity, then the absorption capacity is improved, but the device complexity and logistical effort increase
Solution Approach 1:
The patent employs multiple identical channel bodies with the same nominal width, cross-sectional shape, and structural design. This homogeneity simplifies manufacturing, storage, transport, and assembly operations. The identical channels can be stacked vertically in any number to achieve the desired absorption capacity without requiring different types of channels, thereby reducing device complexity and logistical effort.
3Quantity of substance
If identical channel bodies are stacked one above the other, then the absorption capacity increases and production costs decrease, but the structural stability may be compromised
Solution Approach 1:
The identical channel bodies are stacked vertically one above the other in a nested arrangement, with each channel fitting into the vertical sequence. This nesting configuration allows the channels to support each other structurally while maintaining alignment through their identical geometric features, such as the U-shaped cross-section and standardized dimensions, thereby ensuring structural stability of the stacked arrangement.
4Strength
If the channel width is increased to handle heavy loads, then the load-bearing capacity is improved, but the production costs and material consumption increase
Solution Approach 1:
Instead of using a single wide channel with high material consumption, the system segments the drainage function into multiple narrower identical channels stacked vertically. Each channel maintains sufficient load-bearing capacity for its size, and the cumulative absorption capacity of multiple channels replaces the need for a single oversized channel, thereby reducing overall material consumption while maintaining or improving load-bearing capacity.
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
This configuration doubles the absorption capacity while maintaining the same nominal width, provides greater rigidity, and allows for efficient handling of heavy rainfall and varying terrain slopes, reducing logistical efforts and production costs, while preventing clogging through regular gully cleaning.
Implementation Method 1
The water discharged in the drainage channels is usually fed to a gully by a natural gradient
Implementation Method 2
Suspended matter and other sediments entrained in the water also collect in the gully

AI summary
Drainage system which, by connecting channels of the same nominal width, creates a multi-tier channel such that several drainage channels, each with two lateral channel walls (4, 4') which are closed off on the underside by a channel base (5) and open on the upper side into a preferably right-angled frame area (6, 6'), are each supported by a flat mounting surface (7) which can be inserted flush into the frame of the respective lower drainage channel, wherein, in addition, the multi-tier channels can be connected to each other longitudinally in such a way that, in the direction of flow, the number of drainage channels arranged one above the other within a multi-tier channel increases, so that a cascade gradient can be realized at the same time.
