Traffic Sensing Alarm Assembly for Roadside Safety
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing traffic alarm devices for roadside service workers do not effectively alert workers to approaching traffic, as they lack a radar emitting device that can be integrated with road signs or service vehicles and communicate wirelessly with a wearable alert system.
Innovation Solution
A motion sensing unit that emits a focused beam of electromagnetic energy to detect vehicles, broadcasting an alert signal when interrupted, and a remote alert device worn by the worker that receives this signal to emit an audible alarm, with mounts for attachment to road signs, service vehicle dashboards, or rear view mirrors for directional detection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a radar emitting device is integrated with road signs or service vehicles and communicates wirelessly with a wearable alert system, then the effectiveness of alerting workers to approaching traffic is improved, but the device complexity increases
Solution Approach 1:
The system is divided into separate functional modules: a motion sensing unit with radar capability, a wireless communication module, and a wearable alert device. This segmentation allows each component to perform its specific function independently, reducing overall system complexity while maintaining effectiveness.
Solution Approach 2:
The motion sensing unit is designed to serve multiple functions: detecting motion, determining direction of approaching traffic, and wireless communication. The wearable alert device also provides multiple functions including receiving signals and alerting the worker through audio and visual cues, reducing the need for separate dedicated components.
2Adaptability or versatility
If multiple mounting options are provided for the motion sensing unit, then the adaptability of the system is improved, but the manufacturing complexity increases
Solution Approach 1:
The motion sensing unit incorporates multiple mounting mechanisms that can accommodate different installation scenarios (road signs, service vehicles, portable use). This universal mounting design allows a single device to serve multiple installation purposes without requiring separate specialized components for each mounting type.
Solution Approach 2:
The mounting system includes adjustable and removable features that allow the device to be dynamically configured for different installation locations and orientations. This dynamic mounting capability enables adaptability without permanent fixed installations, simplifying manufacturing compared to creating multiple specialized mounting versions.

AI summary
A traffic sensing alarm assembly includes a motion sensing unit that emits a focused beam of electromagnetic energy to detect a vehicle that passes through the focused beam. The motion sensing unit broadcasts an alert signal when the focused beam is interrupted. A first mount is removably attachable to the motion sensing unit to engage an edge of a road sign. A second mount is removably attachable to the motion sensing unit to rest on a dashboard of a service vehicle that is parked on a roadside. An attachment is removably coupled to the motion sensing unit to engage a rear view mirror on the service vehicle. A remote alert is worn on a service worker's clothing and the remote alert is in wireless communication with the motion sensing unit. The remote alert emits an audible alarm when the motion sensing unit broadcasts the alert signal to alert the service worker to the potential hazard of oncoming traffic.
