Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing flood protection devices often fail to maintain the required accumulation height at the joint between hollow chamber elements due to liquid pressure, leading to inadequate backwater levels.
Innovation Solution
A connecting and sealing element with a hollow body that can be filled with air or water, providing stabilizing means along the upper edge to secure the water level, and featuring valves for fluid connection to adjacent elements, ensuring the desired backwater level is maintained under pressure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If connecting and sealing elements are used to join adjacent hollow chamber elements, then the hollow chamber elements can be connected and sealed in the longitudinal direction, but the upper edge of the connecting/sealing element may break due to liquid pressure, compromising the required accumulation height
Solution Approach 1:
The patent applies this principle by using a flexible hollow body (air cushion) as part of the connecting/sealing element. The hollow body can deform elastically under liquid pressure while maintaining its sealing function, preventing the upper edge from breaking. The flexible nature allows it to absorb pressure without structural failure, ensuring both sealing integrity and pressure resistance.
Solution Approach 2:
The patent applies this principle by incorporating a hollow body that can be filled with air or water into the connecting/sealing element. When filled with air, it creates an air cushion that provides buoyancy and structural support to the upper edge, reinforcing it against liquid pressure. This pneumatic reinforcement ensures the upper edge maintains its position and sealing capability under pressure.
2Reliability
If the hollow body is designed with large width and circumferential extension to stabilize the water level, then the stabilizing effect is enhanced, but the flexibility and ease of transport is reduced
Solution Approach 1:
The patent applies this principle by designing the hollow body with adjustable dimensions. The width and circumferential extension can be adapted based on the specific application requirements. This dynamic adjustability allows optimization of the stabilizing effect for different water level requirements while maintaining transport flexibility by reducing dimensions when full stabilization is not needed.
Solution Approach 2:
The patent applies this principle by allowing the hollow body's geometric parameters (width, circumferential extension) to be varied. By changing these parameters, one can optimize the stabilizing effect for specific applications. The hollow body can be manufactured in different sizes or configured to provide appropriate stability without always requiring maximum dimensions, thus balancing stability with transport ease.

AI summary
The invention relates to a protective barrier (10) for impounding liquids (16), in particular a mobile flood protection device, comprising several hose-like hollow chamber elements (12, 14) that can be filled with fluid such as air or water and which can be connected to one another longitudinally to form a protective dam with a water level SH, wherein in the area of a joint (28) between two hollow chamber elements (12, 14) a preferably skirt-shaped connecting/sealing element (34) is provided that overlaps the joint (28). In order to maintain the water level SH under water pressure on the connecting/sealing element in the area of the joint (28), the connecting/sealing element (34) is provided to have a stabilizing means (54) along an upper edge (52) that forms the water level SH to secure the water level SH.
