Remote Rear-End Collision Alerting for Warning Triangles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional warning triangles and cones rely on passive light reflection, which is ineffective in adverse weather conditions, leading to insufficient reaction time for drivers and increased risk of secondary collisions.
Innovation Solution
A rear-end collision alarm apparatus with an alert detector device mounted on a warning object and an alert receiver device worn by a user, utilizing infrared detection and Bluetooth communication to provide instantaneous alarming flashing lights and sounds when an object enters a detection range, with a horizon switch to ensure verticality and interrupt signaling upon tipping.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If passive light reflection is used in warning triangles and cones, then the device complexity is reduced, but the reliability of alerting is insufficient in adverse weather conditions
Solution Approach 1:
The warning device is divided into two independent parts: a passive warning object (triangle/cone) and an active alert detector device. The detector includes separate functional modules for infrared detection, Bluetooth communication, and alarm signal generation, allowing each component to perform its specific function independently while working together to solve the reliability problem.
Solution Approach 2:
An infrared detection module acts as an intermediary between the warning object and approaching vehicles. It detects vehicles before they reach the warning object and transmits alert signals to drivers through Bluetooth communication, providing advance warning that overcomes the limitation of passive reflection.
2Loss of time
If passive light reflection is used, then the manufacturing cost is reduced, but the reaction time for drivers is insufficient
Solution Approach 1:
The infrared detection module performs preliminary detection of approaching vehicles before they reach the warning object. The system activates alarm signals in advance, giving drivers sufficient reaction time to slow down or change lanes, rather than relying on drivers to react only when they visually observe the warning object.
3Reliability
If active alerting devices are added to warning objects, then the alerting effectiveness is improved, but the device complexity increases
Solution Approach 1:
The alert detector device integrates multiple functions into a single unit: infrared vehicle detection, Bluetooth wireless communication, alarm signal generation, and automatic control. This multi-functional design improves alerting effectiveness while containing complexity within a compact integrated device that can be attached to standard warning objects.

AI summary
A rear-end collision alarm apparatus featuring remote alarming is provided, including an alert detector device and an alert receiver device. The alert detector device is mounted on a preset warning object (such as a warning triangle and a cone). The alert receiver device is worn on or carried by a user. The alert detector device includes a first light source module, an infrared detection module, and a first Bluetooth module. The alert detector device is placeable, together with the warning object, at a predetermined remote distance from a traffic accident or construction site, where the first light source module may serve as a warning through light flashing. When the infrared detection module detects an object entering a detection range, the alert detector device transmits an alert signal through the first Bluetooth module to the alert receiver device to have the alert receiver device instantaneously emit alarming light and alarming sounds.
