Cylindrical Flood Container Lip Arrangement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobile flood protection systems, such as those using sandbags or cylindrical containers filled with water, face logistical challenges including high personnel requirements and instability on uneven surfaces, leading to potential system failure due to floating or shifting containers.
Innovation Solution
Incorporating a lip arrangement on the longitudinal side of the cylindrical container's plate, which provides a downward force when filled with ballast medium, preventing floating and shifting, and allowing secure anchoring without additional ground anchoring measures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If sandbags are used to build dams, then mobile flood protection can be achieved with simple materials and flexible application, but a relatively large amount of personnel is required
Solution Approach 1:
The flood protection system is divided into modular cylindrical containers that can be individually assembled and connected. Each container is formed from a segmented plate structure with detachable end connections, allowing parallel assembly by multiple work teams simultaneously, thereby reducing overall personnel requirements while maintaining flexibility in deployment configurations
Solution Approach 2:
The patent introduces specialized connecting devices as intermediary components that facilitate the assembly process. These connectors enable rapid joining of plate segments and cylindrical containers without requiring manual tying or complex fastening operations, significantly reducing the labor intensity and personnel needs while preserving the system's adaptability
2Ease of operation
If the sack-shaped insert body is not sufficiently attached to the container, then assembly is simplified, but the container may float and water can be pushed through
Solution Approach 1:
The cylindrical container geometry with its curved surface creates favorable mechanical conditions for force distribution. The curvature allows the insert body to be retained through simple friction and normal forces without requiring complex attachment mechanisms, maintaining assembly simplicity while ensuring reliability through geometric constraint
Solution Approach 2:
The patent employs simple, inexpensive retaining elements such as basic clips or friction-based retainers instead of robust permanent fastening systems. These simple retention mechanisms are sufficient for the intended service life of emergency flood barriers, keeping assembly simple while providing adequate reliability for temporary applications
3Adaptability or versatility
If the sack-shaped insert body presses through under the container on uneven ground, then the container is lifted and flood protection is limited, but additional ground anchoring measures would increase complexity
Solution Approach 1:
The lip arrangement extends the base area of the container into a third dimension (vertically downward from the container bottom). This dimensional extension distributes the load over a larger area and creates mechanical interlocking with the ground surface, preventing puncture and lifting without requiring complex horizontal anchoring systems, thereby maintaining simplicity while adapting to uneven terrain
4Productivity
If cylindrical containers are used instead of sandbags, then personnel requirements are reduced, but the containers may float or shift on uneven surfaces
Solution Approach 1:
The cylindrical shape of the containers provides superior stability compared to sandbags. The curved surface area and geometric form resist tipping and shifting forces more effectively than irregular sandbag configurations, maintaining container stability while achieving the personnel efficiency benefits of pre-formed modular units
Solution Approach 2:
The lip arrangement is specifically positioned at the base area of the container where ground contact occurs. This localized feature provides enhanced ground engagement and stability at the critical interface with the terrain, preventing floating and shifting without affecting the overall container design or requiring additional anchoring systems
