Multi-Part Reusable Levee Bag with Biodegradable Bottom
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing levee systems rely on one-time use sandbags that are labor-intensive to fill and cannot be reused, posing challenges in flood control and environmental impact due to their destruction after use.
Innovation Solution
A multi-part reusable levee bag system comprising a top and bottom section, where the bottom section is made of biodegradable material, allowing for mechanized filling and subsequent disassembly, reconditioning, and reuse, with features like baffles and connectors for secure material retention and easy attachment to filling frames.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If one-time use sandbags are used for flood control, then the bags can be easily deployed, but they must be destroyed after use and cannot be reused
Solution Approach 1:
The levee bag is divided into two separable sections: a reusable top section made of durable material and a biodegradable bottom section. This segmentation allows the top section to be recovered and reused while the bottom section decomposes naturally after use, resolving the contradiction between ease of deployment and reusability.
2Device complexity
If traditional sandbags are filled manually, then the bags can be constructed simply, but the process is labor intensive
Solution Approach 1:
The bag design incorporates dynamic opening mechanisms that allow the bag to expand and be filled efficiently. The separable sections can be opened wide for mechanized filling using equipment like backhoes, then closed and secured for transport and deployment, enabling both simple construction and high productivity.
3Productivity
If large volume bags are used for mechanized filling, then filling efficiency increases, but the bags cannot be reused and must be destroyed
Solution Approach 1:
By dividing the large volume bag into a reusable top section and a disposable bottom section, the system enables mechanized filling of large volumes while preserving the ability to reuse the top section. The bottom section is designed to be biodegradable, allowing it to be left in place after use while the top section is recovered and reused in subsequent operations.
4Device complexity
If unitary bag construction is used, then the bag structure is simple, but the bag cannot be disassembled for reuse
Solution Approach 1:
The bag employs a simple yet effective segmentation into two sections connected by removable fasteners. This allows the bag to maintain structural simplicity while enabling easy disassembly for reuse of the top section. The connection mechanism is designed to be straightforward to assemble and disassemble without complex components.

AI summary
A multi-part reusable levee bag. The reusable levee bag includes a top bag section and a bottom portion removably affixed to the top bag section. The combined top bag section and bottom portion define an in interior space within which fillable material may be received to form a levee bag for use in flooding and other installations. The bottom bag section is made of a biodegradable material while the top bag section is made of an alternative material. The reusable levee bag, once filled, may be disassembled and the top bag section reused while the bottom bag section may remain in place while still being environmentally friendly due to its biodegradation.
