Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing danger warning systems for vehicles face challenges in accuracy and timeliness due to limitations in sensing capabilities and communication coverage, failing to consider a wide range of potential threats to driving safety, especially from objects without communication capabilities.
Innovation Solution
A method utilizing a network of environmental monitoring devices deployed outside vehicles to monitor geographical ranges, providing comprehensive sensing data to a computing device that determines the danger degree of objects and issues timely warnings to vehicles based on this data, enhancing accuracy and coverage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If vehicle-mounted sensing devices are used for danger detection, then the system can provide real-time warnings, but the sensing range and detection accuracy are limited
Solution Approach 1:
The system divides the danger detection function into two segments: vehicle-mounted devices for real-time monitoring and roadside environmental monitoring devices for extended coverage. This segmentation allows each component to have specialized functions, improving overall sensing range without requiring the vehicle system to be overly complex
Solution Approach 2:
Roadside environmental monitoring devices act as intermediaries between the vehicle and the surrounding environment. These devices extend the sensing capability by detecting objects in areas beyond the vehicle's direct sensing range and relaying this information to the vehicle's warning system
2Measurement precision
If only vehicle-mounted sensing devices are used, then the system structure is simple, but the detection accuracy and timeliness of danger warnings are insufficient
Solution Approach 1:
The system merges data from multiple sources: vehicle-mounted sensing devices and roadside environmental monitoring devices. By combining these detection systems, the overall detection accuracy improves as multiple devices can cross-validate and supplement each other's observations
Solution Approach 2:
The roadside environmental monitoring devices serve multiple functions: they extend detection range, improve detection accuracy for objects without communication capabilities, and provide early warning for potential dangers. This multi-functionality justifies the added system complexity
3Adaptability or versatility
If the monitoring coverage is expanded to include more geographical ranges, then more potential threats can be detected, but the system complexity and cost increase
Solution Approach 1:
The system expands monitoring coverage by adding a spatial dimension - deploying roadside environmental monitoring devices at multiple locations along the road. This creates a network of detection points that cover broader geographical ranges without requiring each individual device to be overly complex
