Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobile barriers for temporary security areas face a trade-off between mobility and resistance class, where increasing resistance through heavier protective plates complicates setup and assembly, especially for single-person deployment.
Innovation Solution
A mobile protective wall design featuring an energy-absorbing deformation zone in the connecting module between the protective plate and support structure, allowing kinetic impact energy dissipation, thus enhancing resistance without increasing weight.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If protective plates are made heavier to achieve higher resistance class, then protection level is improved, but weight increases making assembly difficult for single person
Solution Approach 1:
The connecting module incorporates a deformation area designed to absorb impact energy before it reaches the protective plate. This pre-cushioning mechanism reduces the kinetic energy of projectiles or fragments, allowing the use of lighter protective plates while maintaining high resistance class. The deformation area acts as an energy-absorbing element that activates upon impact, thereby resolving the contradiction between weight and protection level.
Solution Approach 2:
The connecting module combines materials with different properties: a rigid connection section for structural integrity and a deformation area made of energy-absorbing material. This composite structure allows the lighter protective plate to be effectively supported while the deformation area provides the necessary impact energy absorption, thus achieving high resistance without increasing weight.
2Strength
If protective plates are made heavier to achieve higher resistance class, then protection level is improved, but ease of operation deteriorates
Solution Approach 1:
By incorporating the deformation area in the connecting module, the system achieves high resistance class without increasing protective plate weight. This maintains ease of operation for single-person deployment while ensuring adequate protection against ballistic threats.
3Strength
If protective plates are made heavier to achieve higher resistance class, then protection level is improved, but device complexity increases
Solution Approach 1:
The invention merges the energy-absorbing function with the connecting module that already exists in the barrier system. Instead of adding separate cushioning components, the deformation area is integrated into the connecting module's structure, thereby achieving high resistance class without significantly increasing device complexity.
Solution Approach 2:
The connecting module uses composite construction with a rigid connection section and an energy-absorbing deformation area. This allows the system to achieve high resistance class while maintaining relatively simple overall device structure, as the complexity is localized to the connecting module rather than distributed throughout the entire barrier system.

The design maintains low segment weight while significantly increasing protection class, enabling flexible and reliable setup by a single person, with additional features like splash guard elements preventing lateral penetration.
Implementation Method 1
the resistance class of a barrier constructed from these mobile barriers is limited by their weight... the connecting module for attaching the protective plate to the supporting structure has an energy-absorbing deformation area

AI summary
The invention relates to a mobile protective wall for temporarily shielding regions that are subject to increased security requirements, comprising a base device having a bottom portion and a connector portion and comprising a protective wall segment which can be arranged releasably on the connector portion and has a protective plate that at least hinders protection, a supporting structure with a connection portion which is arranged in the region of the upper edge of the protective plate and corresponds to the connection portion, and a coupling portion which is arranged in the region of the lower edge of the protective plate and is designed to be arranged releasably on the connector portion, and a connection module secured to the supporting structure and to the protective plate to fix the protective plate on the supporting structure. In order to provide a mobile protective wall having protective wall segments which have a high resistance class with low inherent weight, it is provided that the connection module has an energy-absorbing deformation region.
