Motorized Traffic Barrier Display for Remote Maintenance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing traffic control devices in construction zones often expose workers to traffic hazards when maintaining displays, as they require manual access, and lack remote control functionality for updating traffic information.
Innovation Solution
A traffic control device comprising a traffic barrier with a motorized pole and display system that can be remotely controlled, allowing the display to be suspended over the roadway for visibility and swung across the barrier for maintenance, enabling workers to operate without exposure to traffic.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual access to the display is required for maintenance, then the display can be maintained, but workers are exposed to traffic hazards
Solution Approach 1:
A remote control device serves as an intermediary between the operator and the display system. The remote control transmits signals wirelessly to control the display's positioning and operation, allowing workers to maintain the display from a safe position behind the traffic barrier without direct exposure to traffic hazards.
2Loss of information
If the display is positioned over the roadway for visibility, then drivers can see traffic information, but workers need to access the display through traffic zones for maintenance
Solution Approach 1:
The remote control device enables operators to adjust the display's position and content from a protected location, eliminating the need for workers to physically access the display while it is positioned in the hazardous traffic zone for driver visibility.
Solution Approach 2:
The patent replaces manual mechanical adjustment of the display with an automated motorized positioning system controlled remotely. The motorized mechanism allows the display to be positioned and repositioned without manual intervention in the traffic zone, substituting mechanical automation for manual operation in hazardous areas.
3Stability of the object's composition
If the display is fixed in position, then it is stable for drivers, but it cannot be easily maintained or updated
Solution Approach 1:
The display system incorporates a motorized positioning mechanism that allows the display to transition between a stable viewing position for drivers and a maintained position for workers. The system dynamically adjusts the display's position based on operational needs, providing both stability during operation and accessibility during maintenance through remote control.
Solution Approach 2:
The remote control system serves as an intermediary that enables maintenance operations without requiring physical access to the display from hazardous positions. Operators can update and maintain the display from a safe location, combining the benefits of fixed stability with easy maintainability.

AI summary
A temporary traffic control assembly includes a traffic barrier that is positioned in a construction zone of a roadway. A mount is coupled to the traffic barrier and a motor is coupled to the mount. A pole is slidably positioned on the motor such that the motor selectively rotates the pole. A display is coupled to the pole such that the display is visible to drivers on the roadway. The display displays indicia comprising traffic information for the drivers. The display is suspended over the roadway when the motor rotates the pole into a displaying position. Moreover, the display is swung across the traffic barrier when the motor rotates the pole into a maintenance position. In this way a worker standing behind the traffic barrier can manipulate the pole and the display without being exposed to traffic on the roadway. A remote control is manipulated by a user for remotely controlling operational parameters of the motor and the display.
