Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing solutions for managing storm water runoff and erosion are inadequate, particularly in areas prone to flooding, as they fail to effectively control water flow and prevent sediment entry into drainage systems.
Innovation Solution
Modular water drain tank or channel systems comprising a novel supporting structure and geotextile material that allow for controlled water release and sediment restriction, enabling easy assembly and portability for installation in trenches or underground use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional drainage systems are used, then water flow control is limited, but sediment entry cannot be prevented
Solution Approach 1:
The drainage system is divided into modular units with distinct functional zones: an upper chamber for sediment trapping and a lower chamber for water storage and controlled release. This segmentation allows simultaneous achievement of sediment filtration and regulated water flow control through separate mechanical mechanisms in each zone.
Solution Approach 2:
A geotextile material serves as an intermediary layer between the sediment source and the drainage chambers. This mediator filters sediment particles while permitting water passage, preventing sediment entry into the drainage system while maintaining water flow control capabilities through the modular chambers.
2Reliability
If fixed drainage structures are installed, then water retention is achieved, but assembly and portability are compromised
Solution Approach 1:
The drainage system comprises multiple identical modular units that can be independently manufactured, transported, and assembled. Each module contains complete functional elements (chambers, flow control mechanisms, sediment traps), enabling reliable water retention when assembled while maintaining ease of transport and assembly through standardized interfaces and portable individual unit sizes.
Solution Approach 2:
The modular design creates universal units that can be configured for different water retention capacities and flow control requirements by varying the number and arrangement of modules. The same basic module structure serves multiple functions: sediment trapping, water storage, and controlled release, while maintaining portability and assembly ease through standardization.
3Ease of manufacture
If simple drainage channels are used, then construction is easy, but water flow control capability is insufficient
Solution Approach 1:
The system uses simple-to-manufacture modular units with basic geometric shapes and standardized components that are easy to construct. Each module incorporates integrated flow control mechanisms and sediment trapping chambers that, when assembled, provide sophisticated water flow control capabilities without requiring complex individual component manufacturing.
Solution Approach 2:
Multiple simple functional elements are merged within each modular unit: sediment filtration layers, flow control valves, water storage chambers, and structural supports are combined into single manufacturable modules. This merging maintains construction simplicity at the module level while achieving complex water flow control when modules are assembled into the complete drainage system.

AI summary
A water drain tank or channel module (10) includes a structure having a top platen (20) and a bottom platen (22), a plurality of generally vertical support members (26) for supporting at least the top platen (20), the support members (26) being retained in sockets (28) on at least one of the bottom platen (22) and the top platen (26), and optional side walls (19) each including a water-permeable lattice member (24) that is adapted to support an impermeable membrane (32) or water-permeable geotextile material (30) that is capable of controlling the flow of drain water at least out of the module (10) and restricting sediment from entering the module (10). An assembly (11) of such modules (10, 10', 10", 10a, 10b, 10c, 10d) to form a drain tank, channel or storage reservoir is also disclosed.
