Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing driver assistance systems are vehicle-specific, making them inflexible and difficult to calibrate, limiting their universal application across different types and sizes of vehicles.
Innovation Solution
A reconfigurable advanced driver assistance device with a single housing unit containing a common module that adjusts vertically, incorporating stereoscopic and long-range cameras, a LiDAR module, and a microphone array, allowing for calibration and reconfiguration to work with various vehicles, including trucks, cars, and buses, and accommodating both right-hand and left-hand driven vehicles.
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 ready for use, but they cannot be utilized for any other vehicle and require sophisticated calibration tools
Solution Approach 1:
The patent applies universality by designing a calibration device that can be used across multiple vehicle types and models. The device includes a mounting structure that can be adapted to different vehicle windshields and a calibration system that works with various camera modules, making it universally applicable rather than vehicle-specific.
Solution Approach 2:
The calibration device enables self-service calibration by providing an integrated system with target markers, imaging devices, and processing capabilities that allow users to perform calibration without requiring sophisticated external tools or specialized equipment, thus simplifying the calibration process.
2Adaptability or versatility
If a single housing unit with common module is used, then universal compatibility across vehicle types is achieved, but the system requires reconfigurable mechanisms for different vehicle configurations
Solution Approach 1:
The patent applies dynamics by incorporating a reconfigurable common module that can move along an axis to adjust the vertical angle. This dynamic adjustment capability allows the same hardware to be adapted to different vehicle types (trucks, cars, buses) and configurations (right-hand or left-hand driven) without requiring completely different systems.
Solution Approach 2:
The calibration device is segmented into distinct functional modules: a mounting structure, a common module with camera assemblies, and a processing device. This segmentation allows each module to be independently configured and adjusted for different vehicle types while maintaining overall system functionality.
3Adaptability or versatility
If multiple camera modules with different focal lengths are integrated, then both close-range and long-range detection capabilities are provided, but the device structure becomes more complex
Solution Approach 1:
The patent merges multiple camera modules with different focal lengths (first camera module with short focal length for close-range, second camera module with long focal length for long-range) into a single integrated common module. This combining approach provides comprehensive detection coverage while consolidating the structure rather than using separate independent systems.
Solution Approach 2:
The common module is designed as a multi-functional unit that houses camera assemblies with different focal lengths, allowing it to perform both close-range and long-range detection tasks. This universal module can be applied across different vehicle types and configurations, reducing the need for multiple specialized devices.

AI summary
The present invention provides a vehicle mountable universal driver assistance device. This device includes a housing unit encasing a common module on which are mounted a first camera module, a second camera module, different from the first camera module, and a ranging module. The common module may be moved along an axis to adjust the viewing angle of the first camera, second camera and ranging module. The device can be mounted on windshield of any vehicle and can be calibrated accordingly. The warning from the warning display device is based on the detection of the misalignment of the common module.
