Ballistic Protection Coupling Element for Blast Pressure Decoupling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional protective equipment for objects against military threats fails to effectively combine ballistic and blast protection, as ballistic elements are inadequate against blast effects and require complex structural reinforcements like ribbing.
Innovation Solution
Incorporating a coupling element between supports of ballistic protection elements to pressure-decouple and tension-couple the protective element with the outer surface, allowing elastic deformation to absorb blast forces without compromising ballistic protection, and using a damping element to prevent overloading.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If ballistic protection elements are arranged on supports close to the outer surface, then ballistic protection is improved, but protection against blast effects deteriorates because the elements bend and give way under blast pressure
Solution Approach 1:
A coupling element is introduced as an intermediary between the ballistic protection element and the outer surface. This coupling element enables tensile coupling to maintain ballistic protection while实现ing pressure decoupling to allow blast pressure to act without transmitting harmful forces to the protected object. The coupling element mediates between the conflicting requirements of rigid attachment for ballistic protection and flexible attachment for blast protection.
2Object-affected harmful factors
If complex structural reinforcements like ribbing are added to protect against blast effects, then blast protection is improved, but device complexity increases
Solution Approach 1:
The function of blast protection is extracted from the complex structural reinforcements (ribbing) and transferred to the coupling element. By removing the need for complex structural modifications and using a simple coupling element instead, the patent achieves blast protection without increasing device complexity. The coupling element alone suffices to decouple pressure while maintaining tensile connection.
3Object-affected harmful factors
If ballistic protection elements are arranged at a distance from the outer surface, then blast protection is improved by allowing deformation space, but ballistic protection deteriorates because the elements are less effective
Solution Approach 1:
The coupling element acts as a mediator that allows the ballistic protection element to be positioned at an optimal distance from the outer surface. This distance provides necessary deformation space for blast protection while the coupling element maintains secure attachment for ballistic protection. The intermediary enables both requirements to be satisfied simultaneously by providing controlled connection.
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
This solution provides enhanced protection against blasts without sacrificing ballistic protection and can be easily integrated into existing systems, reducing the need for extensive structural reinforcements.
Implementation Method 1
the protective element be elastically freely flexible under the action of a blow in the region of the coupling element in the direction of the outer surface until it collides with the outer surface. Due to the freely deflectable arrangement of the elastic protective element, this can deform elastically in the direction of the underlying outer surface of the object to be protected as a result of a blast effect.
Implementation Method 2
After the collision of the elastically deformed protective element with the outer surface, it stops according to the laws of momentum transfer, transferring its energy to the outer surface of the object to be protected. The outer surface begins to deform towards the interior of the object to be protected.
Implementation Method 3
At the same time, the elastically deformed protective element begins to spring back in a direction opposite to the direction of deformation of the outer surface. In this case, a tensile force is applied via the tensile coupling of the coupling element to the outer surface of the object to be protected, which counteracts the buckling of the outer surface of the object to be protected.

AI summary
The equipment has a coupling element (6) provided between two supports (3, 4). Ballistic protection bars (2) are pressure-decoupled or train-coupled connected with one another over an outer surface (5) of the equipment. The protection bars are pulled by back springs over the coupling element at the outer surface. LED ends of the coupling element are provided with a behind grip and inserted into an aperture of the protection bars. A damping element is placed opposite to a protection element.
