Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Drivers often struggle to detect approaching vehicles in sharp curved sections of roads due to limited visibility, leading to frequent traffic accidents.
Innovation Solution
An information processing method and electronic device that obtain and analyze images of curves using wide-angle cameras, identify vehicle positions, determine geographic positions, and generate prompt information to calculate vehicle spacing and issue warnings based on GPS or other positioning technologies.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If drivers rely on their own vision to detect approaching vehicles, then they can maintain normal driving operation, but they cannot detect vehicles in time due to limited vision on curves
Solution Approach 1:
The patent introduces an electronic device as an intermediary that includes an image acquisition unit to capture images of the curve, a processing unit to analyze the images and identify vehicle positions, and a communication unit to transmit warnings to drivers. This intermediary system overcomes the limitation of human vision by providing automated vehicle detection and warning capabilities on curved road sections.
2Reliability
If no warning system is installed, then the device complexity is low, but traffic accidents occur frequently due to limited driver vision
Solution Approach 1:
The patent replaces the mechanical/physical limitation of human vision with an electronic system that uses image acquisition devices, processing units, and communication systems. This substitution enables automated detection and warning capabilities that significantly improve traffic safety on curves while managing the complexity through integrated electronic components.
3Measurement precision
If wide-angle cameras and image processing are used to detect vehicles, then vehicle detection accuracy is improved, but the device complexity and cost increase
Solution Approach 1:
The patent transitions from one-dimensional linear road monitoring to two-dimensional curved road monitoring by deploying image acquisition devices at strategic locations on curves. This dimensional change enables comprehensive coverage of the curved road section, allowing the system to detect vehicles approaching from different angles and positions with high precision.
