Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing explosion-proof and bullet-proof wall constructions are complex, costly, heavy, and inefficient, failing to provide effective protection in a simple and cost-effective manner.
Innovation Solution
A wall construction comprising two barriers with obliquely directed protective slats that absorb and deflect shock waves and projectiles, transferring forces to vertical frames and the ground, with an innermost empty zone to disperse energy, and a self-supporting framework for rapid assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional explosion-proof and bullet-proof wall constructions are used, then protection against explosions and bullets is provided, but the construction becomes complex, heavy, and expensive to reconstruct
Solution Approach 1:
The wall construction is divided into multiple functional layers: a first barrier with obliquely directed slats for shock wave deflection, an innermost empty zone for energy dispersion, and a second barrier for final protection. This segmentation allows each layer to perform a specific function, simplifying the overall design while maintaining effectiveness.
Solution Approach 2:
The protective slats are arranged obliquely rather than vertically or horizontally, creating a three-dimensional configuration that efficiently deflects shock waves and projectiles. This angular arrangement in multiple dimensions provides superior protection compared to conventional flat wall structures.
2Reliability
If conventional explosion-proof and bullet-proof wall constructions are used, then protection against explosions and bullets is provided, but the construction becomes heavy
Solution Approach 1:
By dividing the wall into separate functional barriers with an empty zone between them, the design eliminates the need for heavy concrete or steel monolithic structures. Each barrier can be constructed from lighter materials optimized for its specific protective function.
Solution Approach 2:
The innermost empty zone acts as a cushioning space that absorbs and disperses explosion energy before it reaches the second barrier. This pre-cushioning effect reduces the structural requirements and weight of the protective barriers.
3Reliability
If conventional explosion-proof and bullet-proof wall constructions are used, then protection against explosions and bullets is provided, but the construction is expensive to reconstruct
Solution Approach 1:
The modular segmented design allows individual barriers and slats to be replaced independently if damaged, rather than requiring complete wall replacement. This reduces reconstruction costs and time while maintaining protection effectiveness.
Solution Approach 2:
The slats and barrier elements are designed as replaceable components that can be easily substituted if damaged by explosions or projectiles, providing a cost-effective solution compared to replacing entire heavy-duty protective walls.
4Reliability
If conventional explosion-proof and bullet-proof wall constructions are used, then protection against explosions and bullets is provided, but the construction is not efficient in absorbing shock waves
Solution Approach 1:
The oblique arrangement of slats at specific angles creates efficient shock wave deflection paths. The three-dimensional angular configuration naturally channels and dissipates explosion energy, providing superior shock wave absorption with a simple geometric design.
Solution Approach 2:
The empty innermost zone, which might seem like wasted space, actually serves as an efficient energy absorption chamber that converts explosion kinetic energy into dispersed motion, protecting the protected object without requiring complex active protection systems.

Implementation Method 1
the slats extend horizontally between a first post and a second, adjacent post of a barrier, wherein the protective slats are directed obliquely upwards, extending from outside to inside, in order to absorb a shock wave of an incoming explosion or an incoming projectile and to deflect it upwards
