Vehicle Brake Lamp Visual Recognition Failure Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle failure detection systems cannot confirm whether a brake lamp is visually recognizable from outside the vehicle, limiting the detection of failures that are not electrical in nature.
Innovation Solution
A failure detection system using wireless communication between in-vehicle devices and vehicle-mounted devices, where an imaging device captures images of the vehicle's surroundings to determine if the brake lamp is lighting and transmits this information for verification, allowing for accurate detection of visual recognition failures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If electrical detection methods are used to detect brake lamp failures, then the detection can be performed through circuit conditions, but it is not possible to confirm whether lighting is actually visually recognizable from the outside
Solution Approach 1:
The patent introduces an imaging device as an intermediary component that captures images of the brake lamp to verify its visual recognition. This mediator bridges the gap between electrical detection and visual confirmation, allowing the system to detect failures that electrical means alone cannot identify.
Solution Approach 2:
The patent replaces purely electrical detection methods with an optical imaging system. By using an imaging device to capture and analyze images of the brake lamp, the system substitutes electrical circuit analysis with visual/optical detection, enabling confirmation of actual visual recognizability.
2Reliability
If only electrical detection is used, then the detection system remains simple, but failures that are not detectable by electrical means cannot be identified
Solution Approach 1:
The patent merges electrical detection systems with imaging devices to create a hybrid detection system. By combining these two different detection approaches, the system achieves higher reliability by capturing both electrical circuit status and visual recognition status of the brake lamp.
Solution Approach 2:
The imaging device serves multiple functions: it captures images for visual recognition verification, provides feedback for system diagnostics, and can potentially detect other lighting failures. This multi-functionality increases reliability without proportionally increasing system complexity.
