Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Unmanned vehicles face challenges in quickly identifying casualties and responding to pedestrian accidents due to limited space for pedestrian detectors and emergency call devices, especially with transparent front glass structures, which hinder immediate injury assessment and appropriate medical response.
Innovation Solution
A collision accident response system for unmanned vehicles, featuring a transparent pressure sensor film on the front glass with embedded infrared detection units and a controller to determine collision strength, height, and direction, triggering an emergency call to appropriate medical facilities based on injury assessment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a transparent glass structure is applied to the front surface of the unmanned vehicle, then visibility and aesthetic appearance are improved, but space for mounting pedestrian accident detectors is reduced
Solution Approach 1:
The patent combines the pedestrian accident detector with the transparent glass structure itself. The detector is integrated into the glass, allowing the glass to serve dual purposes: maintaining visibility while functioning as the detection surface. This eliminates the need for separate detector mounting space.
Solution Approach 2:
The transparent glass is designed to perform multiple functions simultaneously: it serves as the transparent front surface for visibility and as the mounting substrate for the pedestrian accident detector. This multi-functionality resolves the space conflict by making the glass itself the detector platform.
2Reliability
If emergency call devices are mounted on the vehicle to transmit accident information, then emergency response capability is improved, but available space is further limited and operation requires occupant intention
Solution Approach 1:
The emergency call device is integrated with the controller that receives data from the pedestrian accident detector. This combination allows the system to automatically trigger emergency calls based on detector signals, eliminating the need for separate device mounting space and removing the requirement for occupant action.
Solution Approach 2:
The system is designed to automatically detect pedestrian accidents and initiate emergency responses without requiring occupant intervention. The controller automatically processes detector signals and activates the emergency call device, making the system self-operating and eliminating the need for manual activation.
3Measurement precision
If traditional detector placement is used, then detection function is achieved, but quick identification of casualties and injury assessment is delayed
Solution Approach 1:
The system performs preliminary detection by continuously monitoring for pedestrian accidents through the integrated detector. Upon detecting an accident, it immediately assesses casualty information and initiates emergency responses in advance, significantly reducing the time lag between accident occurrence and medical intervention.
