Solution Overview
Problem
Vehicles face challenges in detecting dangerous objects in their lateral blind zones obscured by other vehicles, leading to potential collisions due to short reaction times.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the vehicle uses conventional detection systems to detect dangerous objects, then objects visible in front of the vehicle can be detected, but objects in lateral blind zones obscured by other vehicles cannot be detected
Solution Approach 1:
The patent uses the adjacent vehicle as an intermediary target. Instead of directly detecting objects in the blind zone, the system detects the adjacent vehicle's movement characteristics (acceleration, braking, turning) which indicate the presence of dangerous objects. The adjacent vehicle serves as a mediator that reveals information about hidden objects through its behavioral changes.
Solution Approach 2:
The system performs preliminary detection by monitoring the adjacent vehicle before the dangerous object becomes visible to the first vehicle. By detecting changes in the adjacent vehicle's movement characteristics while it is still in the blind zone, the system can alert the driver in advance, providing early warning before the object suddenly appears in front of the vehicle.
2Reliability
If the vehicle waits until the dangerous object appears in front of the vehicle to react, then the detection system can identify the object, but the reaction time is too short to avoid collision
Solution Approach 1:
The system performs preliminary detection by monitoring the adjacent vehicle's movement characteristics before the dangerous object becomes visible to the first vehicle. By detecting changes in the adjacent vehicle's acceleration, braking, or turning behavior, the system can alert the driver in advance, providing early warning before the object suddenly appears in front of the vehicle.
Solution Approach 2:
The system establishes a feedback loop by continuously monitoring the adjacent vehicle's movement characteristics and comparing them against normal driving patterns. When abnormal movements are detected (such as sudden braking or sharp turning), the system provides feedback to the driver through alerts, enabling timely response to potential hazards in the blind zone.
3Reliability
If the vehicle installs multiple detection devices to cover blind zones, then detection coverage is improved, but the device complexity and cost increase
Solution Approach 1:
The system leverages the adjacent vehicle's own movement characteristics as the detection resource. Instead of requiring the first vehicle to install additional sensors to monitor the blind zone, the system uses the adjacent vehicle's natural behavioral responses to hidden objects as the detection mechanism. The adjacent vehicle essentially serves itself by revealing the presence of dangerous objects through its movement changes.
Solution Approach 2:
The system makes the existing adjacent vehicle serve multiple functions: it remains a normal traveling vehicle while simultaneously acting as a detection probe for the first vehicle's blind zone. This multi-functionality eliminates the need for dedicated detection devices on the first vehicle, as the adjacent vehicle's monitoring role is integrated into its normal operation.
