Innovation Solution
A cornering light structure that uses a distance measurement device, such as ultrasonic sensors, to detect the banking angle of the vehicle body, allowing for a cost-effective and flexible configuration by integrating the light main body and detection device into an integral unit, which can be attached to various vehicle components, and includes features like symmetric arrangement and adaptive detection regions to enhance measurement accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If IMU-based cornering light systems are used to detect banking angle, then detection accuracy is improved, but costs increase significantly
Solution Approach 1:
The patent replaces the IMU (inertial measurement unit)-based detection system with a simpler optical detection system using a detection device that measures the position of the vehicle body relative to the ground. This substitution maintains sufficient detection accuracy for cornering light activation while dramatically reducing component costs and manufacturing complexity.
Solution Approach 2:
The patent employs a cost-effective detection device instead of expensive IMU components, accepting that the detection system is simpler and potentially less durable, but sufficient for the specific application of cornering light control. This approach prioritizes cost reduction while maintaining functional adequacy.
2Reliability
If dedicated components and designs are used for cornering light, then detection accuracy and reliability are improved, but adaptability across different vehicle models decreases
Solution Approach 1:
The patent designs the cornering light system with a universal detection device and control logic that can be adapted to multiple vehicle models without requiring model-specific dedicated components. The detection device measures relative position in a way that works across different vehicle geometries, and the control system adjusts illumination based on detected banking angle regardless of the specific vehicle model.
Solution Approach 2:
The patent separates the cornering light function into independent modules: a detection device that measures relative position, a control system that processes the detection results, and the illumination system. This modular segmentation allows the same basic architecture to be applied across different vehicle models while maintaining reliability through standardized interfaces and protocols.
3Ease of manufacture
If opening is formed on vehicle body exterior for light main body, then light installation is simplified, but vehicle body structure complexity increases
Solution Approach 1:
The patent combines the detection device and light main body into an integrated assembly that can be mounted as a single unit. This merging eliminates the need for separate openings for detection and illumination components, reducing vehicle body structure complexity while maintaining ease of installation through a unified mounting process.
