Boom Gate Arm with Angled Segments for Barrier Clearance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing boom gates require a larger area when used in combination with traffic management barriers due to the horizontal arm's inability to extend over these barriers, complicating traffic management in high-traffic areas.
Innovation Solution
A boom gate design featuring an elongate arm with two horizontal axes spaced apart, allowing it to be used in close proximity with barriers, where the arm's first portion is adjacent the fixed end and the second portion is adjacent the free end, connected by angled sections, enabling the arm to be extended over barriers, and the pedestal can be attached to the barrier for space-saving installation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the boom gate arm is positioned horizontally to block access, then the gate can effectively prevent vehicle passage, but the gate cannot be used in close proximity with barriers requiring a larger area
Solution Approach 1:
The boom gate arm transitions from a purely horizontal configuration to a multi-dimensional configuration with angled portions. The arm includes a first horizontal portion, a first angled portion, and a second horizontal portion, allowing the arm to extend both horizontally and at angles. This dimensional change enables the arm to clear barriers while maintaining blocking functionality, reducing the area required when used in combination with barriers.
2Adaptability or versatility
If the boom gate arm extends horizontally across the lane, then it can effectively block access, but it cannot extend over barriers placed in the lane
Solution Approach 1:
The boom gate arm is segmented into multiple distinct portions: a first horizontal portion adjacent the fixed end, a first angled portion, and a second horizontal portion adjacent the free end. These segments are connected through pivot joints, allowing independent movement and positioning. This segmentation enables the arm to navigate over barriers while maintaining the blocking function, and the modular structure facilitates easier manufacturing and maintenance compared to a single complex piece.

AI summary
A boom gate including: a pedestal locatable on a surface and an elongate arm to extend across an area to be temporarily blocked; the elongate arm having a free end and a fixed end, the fixed end being pivotably attached to the pedestal and driven by a drive mechanism to permit the arm to move between a generally horizontal position and a generally vertical position, preventing or allowing access past the gate, respectively; the arm including a first elongate portion defining a first horizontal axis and a second portion defining a second horizontal axis, the first and second axes being spaced away from each other to permit the gate to be used in combination with a traffic management barrier.
