Solution Overview

Problem

Existing anti-slosh devices for liquid tanks in vehicles lack precise control over damping effects due to variable alignment and position of anti-slosh elements, leading to inconsistent performance and often require oversizing.

Innovation Solution

The anti-slosh device incorporates both microstructure from the textile fabric's structure and a predefined macrostructure arrangement, allowing for precise design and dimensioning, with a spatially ordered shape that enhances damping and can be easily fastened in the tank.

Engineering Contradictions & Design Principles

Solution Approach 1:

The anti-slosh elements are pre-formed with a specific spatially ordered shape structure before installation. This preliminary shaping ensures that when the elements are placed in the tank, they automatically assume the correct orientation and position, eliminating the need for complex alignment procedures while guaranteeing consistent damping performance.

Inventive Principle:

Solution Approach 2:

The invention changes the geometric parameters of the anti-slosh elements by giving them a predefined spatially ordered shape structure. This shape parameter modification ensures that the elements interact with the sloshing liquid in a controlled manner, providing reliable and consistent damping effects without requiring complex installation procedures.

2Reliability

If the anti-slosh device is oversized to ensure sufficient damping, then the damping effect is improved, but the weight and volume of the device increase

Engineering Contradiction:

Solution Approach 1:

The anti-slosh elements are designed with a spatially ordered shape structure that concentrates damping material in the most effective locations. This local optimization ensures that the damping effect is maximized in critical areas while minimizing the overall volume and weight of the device, eliminating the need for oversizing.

Inventive Principle:

Solution Approach 2:

The invention uses textile fabric with specific structural properties to create anti-slosh elements that provide high damping effectiveness per unit volume. The composite structure of the textile material allows for optimized performance-to-weight ratio, enabling sufficient damping without excessive weight and volume.

Solution Approach 1:

Multiple layers of knitted fabric are merged into a single integrated anti-slosh element with a predefined spatially ordered shape structure. This combining of multiple layers into one unit eliminates the need for separate fastening operations, significantly simplifying the installation process while maintaining the cumulative damping effect of multiple fabric layers.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The multiple fabric layers are pre-assembled and pre-shaped into the final spatially ordered configuration before installation. This preliminary assembly ensures that the complex multi-layer structure is ready for simple drop-in installation, eliminating the need for complex fastening operations inside the tank while preserving the enhanced damping effect of multiple layers.

AI summary

The present invention relates to a sloshing protection device for dampening sloshing movements of a liquid medium in a tank, comprising a sloshing protection element formed by a textile fabric, which is at least partially fluid-permeable, for dampening sloshing movements, and a fastening element for securing the sloshing protection element in the tank. The sloshing protection element has a microstructure, defined by the structure of the textile fabric, for dampening the sloshing movements. The sloshing protection element also has a macrostructure, generated by an arrangement, in particular a shaping, of the textile fabric for dampening the sloshing movements.
