Bendable Barrier Boom Cord Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Bendable barrier booms used in vehicle barriers are heavy due to the requirement of a metal chain for support, limiting their length and increasing production costs, and they cannot be illuminated due to space constraints from the chain and metal profile, which impairs light distribution.
Innovation Solution
A bendable barrier boom design using a cord, such as steel or stretch-resistant plastic, to maintain the second barrier boom section in a horizontal position, allowing for LED illumination and reducing weight and production costs, with a profile element for increased torsional stiffness and light guidance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a metal chain and metal profile are used to support the second barrier boom section, then the structural strength and stability are improved, but the weight of the barrier boom increases significantly
Solution Approach 1:
The patent extracts and removes the heavy metal chain and metal profile from the barrier boom structure. Instead, it uses a cord (made of steel or stretch-resistant plastic) arranged in the first barrier boom section to maintain the horizontal position of the second section, significantly reducing the overall weight while maintaining the necessary structural support
Solution Approach 2:
The patent changes the material parameter from heavy metal (chain and profile) to lighter materials (cord made of steel or stretch-resistant plastic). This parameter change maintains the functional requirement of supporting the second barrier boom section while dramatically reducing the weight of the moving barrier boom
2Stability of the object's composition
If a metal chain and metal profile are installed in the first barrier boom section, then the second barrier boom section can be maintained in horizontal position, but the available space for LED illumination is reduced
Solution Approach 1:
The patent extracts the metal profile that occupied internal space and replaces it with a cord arrangement. The cord is arranged in the first barrier boom section parallel to its longitudinal axis and tightened around two guide rollers, one connected to the barrier column and the other forming the joint axis. This extraction creates sufficient internal space within the first barrier boom section to accommodate LED strips for illumination while maintaining the horizontal stability of the second section
Solution Approach 2:
The patent uses a flexible cord (made of steel or stretch-resistant plastic) instead of a rigid metal profile. This flexible element can be arranged within the first barrier boom section without occupying excessive space, allowing LED strips to be installed on the inner surface of the first section while the cord maintains the necessary mechanical stability
3Reliability
If a heavy chain is used to support the barrier boom sections, then the structural integrity is maintained, but the drive loading increases and requires high performance drives
Solution Approach 1:
The patent changes the weight parameter of the support system from heavy metal chain to lighter cord material. This parameter change directly reduces the gravitational load on the drive mechanism while the cord's tensile strength maintains the necessary structural integrity. The result is reduced drive loading that allows for smaller, more cost-effective drive systems
Solution Approach 2:
The patent extracts the heavy chain that caused excessive drive loading and replaces it with a lighter cord arrangement. The cord is arranged in the first barrier boom section and tightened around guide rollers to maintain the horizontal position of the second section, achieving the same structural support function with significantly reduced weight and drive requirements
4Length of moving object
If the barrier boom is made longer to extend across large installation length, then the coverage area is improved, but the weight and drive loading increase
Solution Approach 1:
The patent changes the material parameter from heavy metal chain to lighter cord material, enabling the barrier boom to be made longer without proportionally increasing the weight. The cord arrangement in the first barrier boom section maintains structural integrity over extended lengths, allowing the barrier boom to cover large installation areas while keeping the weight and drive loading manageable

AI summary
A bendable barrier boom (1) designed to serve as a vehicle barrier, comprises a boom column, a barrier boom (1), and a drive for pivoting the barrier boom (1) between the blocked and the open position. The barrier boom includes a first barrier boom section (2), which is connected to the drive for pivoting the barrier boom (1), and a second barrier boom section (3), which is connected to the first barrier boom section (2) via an articulated joint (4). To maintain the second barrier boom section (3) in the horizontal position, provision is made for a cord (5) arranged in the first barrier boom section (2) parallel to its longitudinal axis that is tightened and clamped around two guide rollers (6, 8). The cord (5) and guide rollers (6, 8) operate to maintain the second boom section in the horizontal position.
