Textile Kinetic Energy Brake With Downstream Anchoring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing textile brakes experience sudden dynamic stresses and movement during engagement, causing damage and requiring large coverage areas, while the straps are not protected from external elements.
Innovation Solution
A kinetic energy absorption device with bundles of straps secured by a 'tearing' connection means, where the anchoring means is arranged downstream of the straps, allowing progressive stress absorption and protection within a stationary storage area, and the straps are housed in a conditioning chamber to prevent damage from external elements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If the bundles of straps are arranged in traditional textile brakes with anchoring means upstream, then the straps can be deployed to absorb kinetic energy, but the storage area is set in motion generating dynamic stresses that cause damage to the vehicle and require large coverage areas
Solution Approach 1:
The patent inverts the traditional arrangement by placing the anchoring means downstream of the bundle of straps instead of upstream. This reversal causes the straps to deploy in the opposite direction during braking, keeping the storage area stationary and preventing dynamic stresses from damaging the vehicle while maintaining effective kinetic energy absorption.
2Force
If the bundles of straps are arranged in traditional textile brakes, then the straps can be deployed to absorb kinetic energy, but the movement of the modules during engagement requires a large coverage area
Solution Approach 1:
By inverting the arrangement to place anchoring means downstream, the straps deploy away from the storage area rather than moving it. This allows the braking system to function effectively within a smaller, fixed coverage area while maintaining the force absorption capability.
3Device complexity
If the straps are exposed to external elements, then the device can be simpler in structure, but the straps are damaged by water, mould, animals and other potential external attacks reducing their lifespan
Solution Approach 1:
The patent employs a protective covering or shell that encloses the straps, protecting them from water, mould, animals and other external attacks. This flexible protective layer maintains structural simplicity while significantly extending the lifespan and reliability of the straps by shielding them from environmental damage.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The device absorbs kinetic energy without moving the storage area, maintaining mechanical stability and extending the life of the straps by preventing damage from stress and environmental factors.
Implementation Method 1
The means for connecting the two strands of the straps is progressively destroyed, thus allowing the energy of the moving aircraft to be absorbed
Implementation Method 2
capable of being progressively destroyed by a tensile force applied by the vehicle or any other moving body that engages the brake
Implementation Method 3
each strap comprises two strands capable of being separated. The strands are secured by a connection means capable of being progressively destroyed by a tensile force

AI summary
A device for absorbing kinetic energy of a vehicle or any other moving body includes at least one bundle of straps formed by at least one strap having at least one first strand and at least one second strand secured by a connection means capable of being progressively destroyed by a tensile force intended to be applied on the first strand of the strap. The device also includes at least one anchoring means suitable for connecting the kinetic energy absorption device to a structure on which is intended to be installed. The anchoring means is arranged downstream of the bundle of straps with respect to a deployment direction of the strap under the tensile force intended to be applied on the first strand of the strap.
