Emergency Opening Guide Wall Element with Movable Drive Unit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle restraint systems face challenges in creating emergency openings without compromising the system's restraining effect, as conventional lightweight emergency opening baffle elements are weak and complex, while heavy equipment is required to move conventional guide wall elements.
Innovation Solution
A mobile emergency opening baffle element with a concrete body and a travel unit that can be moved from a rest position to a travel position, allowing it to be removed without cranes, maintaining the system's high restraining effect and simplicity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If conventional guide wall elements are made heavy to ensure high restraint effect, then the restraint effect is improved, but heavy equipment such as cranes is required to move them for creating emergency openings
Solution Approach 1:
The guide wall element is divided into a stationary concrete body portion and a movable guide wall portion. The concrete body remains fixed to maintain restraint effect, while the guide wall portion can be manually moved to create emergency openings, eliminating the need for heavy equipment.
Solution Approach 2:
The movable guide wall portion is extracted as a separate component from the heavy concrete body. This allows the guide wall function to be moved manually while the concrete body remains stationary, providing both high restraint effect and ease of operation for emergency openings.
2Ease of operation
If emergency opening barrier elements are made lightweight to enable manual movement, then ease of operation is improved, but the restraint effect is significantly weakened
Solution Approach 1:
The system segments the heavy concrete body from the lighter guide wall portion. The concrete body provides the necessary weight for restraint effect, while the separate guide wall portion can be moved manually, achieving both high strength and ease of operation.
Solution Approach 2:
The movable guide wall is extracted as a separate, lighter component from the heavy concrete body. This extraction allows manual movement for ease of operation while the remaining concrete body maintains the high restraint effect.
3Ease of operation
If emergency opening barrier elements are made of different material (steel) to reduce weight, then ease of operation is improved, but the restraint effect is weakened and design complexity increases
Solution Approach 1:
Different parts of the guide wall element have different properties: the concrete body is heavy and stationary for restraint effect, while the guide wall portion is lighter and movable for ease of operation. This local differentiation of properties resolves the contradiction without requiring complex designs.
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
Enables quick and reliable formation of emergency openings without weakening the vehicle restraint system, maintaining high restraining effectiveness and simplicity in design and production.
Implementation Method 1
The mass of the concrete body and the friction between the mounting surface and the ground also achieve a restraint effect similar to that of a conventional guide wall element.

AI summary
In the case of an emergency opening guide wall element (1) comprising a concrete body (2) and a mounting surface (5), wherein the mounting surface (5) spans a mounting plane, it is proposed that the emergency opening guide wall element (1) has at least one drive unit (3), that the at least one drive unit (3) is designed to be movable between a rest position and a driving position, that the at least one drive unit (3) is arranged completely on a side of the mounting plane facing the concrete body (2) in the rest position, and that the at least one drive unit (3) penetrates the mounting plane in the driving position for driving the emergency opening guide wall element (1) on the at least one drive unit (3).
