Innovation Solution
A universal advanced driver assistance device with a single housing unit containing a reconfigurable common module, featuring stereoscopic cameras for close-range detection, long-range cameras, LiDAR for distance measurement, and a microphone array, allowing for adjustable vertical viewing angles and field of view, enabling easy calibration and adaptation for various vehicle types and driving configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If driver assistance systems are in-built into vehicles, then they are already calibrated and provide vehicle-specific assistance, but they cannot be utilized for any other vehicle and require sophisticated calibration tools
Solution Approach 1:
The patent implements a universal driver assistance system with a single housing unit that can be mounted on different vehicle types (cars, trucks, buses) and configured for various driving configurations (left-hand or right-hand driven vehicles). The system uses multiple camera modules with different focal lengths and a ranging module that can detect objects at various distances, providing adaptability across diverse vehicle applications without requiring vehicle-specific calibration tools
Solution Approach 2:
The system employs a reconfigurable common module where the camera modules and ranging module can be positioned at different locations on the housing unit. The field of view of these sensors can be adjusted by changing their physical positions, enabling dynamic adaptation to different vehicle types and driving configurations without complex calibration procedures
2Measurement precision
If multiple camera modules with different focal lengths are used, then close-range and long-range detection capabilities are improved, but the device structure becomes more complex
Solution Approach 1:
The patent combines multiple camera modules with different focal lengths (first camera module with short focal length for close-range detection, second camera module with long focal length for long-range detection) and a ranging module into a single integrated housing unit. This merging approach provides comprehensive detection capabilities across various distances while maintaining a unified, manageable device structure rather than separate complex systems
Solution Approach 2:
The system addresses detection needs across different distance dimensions by incorporating camera modules with different focal lengths. The first camera module detects objects in close-range vicinity while the second camera module detects objects in long-range vicinity, effectively covering multiple spatial dimensions without requiring overly complex individual modules

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The device provides a flexible and adaptable solution for different vehicles, enhancing driver assistance with advanced warning and alert features, and can be easily calibrated for trucks, cars, and buses, as well as reconfigured for left- or right-hand driven vehicles, improving safety and usability.
Implementation Method 1
a ranging module, arranged on the common module, such that it is in close proximity to the second camera module, and it is configured to detect distance between the vehicle with frontal object
Implementation Method 2
a first camera module (comprises a stereoscopic camera) of a short focal length that detects activity within a close-rage vicinity of the vehicle and distance of objects within the close-range vicinity
