Vehicle Navigation System for Black Box Posture Monitoring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicle black boxes provide only superficial information and fail to effectively determine the posture or position of a vehicle, which is crucial for accurately assessing accidents and negligence ratios.
Innovation Solution
A vehicle navigation apparatus that includes a storage unit for normal posture data, a communication unit for data exchange with the vehicle black box, and a controller to analyze and compare present posture data with stored data, ensuring the black box or camera is positioned correctly, using sensors and image analysis to display reference lines and guide the driver to adjust the device to a normal posture.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If conventional vehicle black box is used, then the device structure is simple, but the information provided is only superficial and cannot effectively determine vehicle posture or position
Solution Approach 1:
The patent combines the black box device with multiple sensors (acceleration sensor, gyro sensor, camera) and integrates them into a unified system. The controller processes data from all these components together to comprehensively determine vehicle posture and position, transforming a simple recording device into an integrated monitoring system that provides deep, multi-dimensional information about vehicle state during accidents.
2Manufacturing precision
If the black box or camera is not positioned correctly, then the device structure remains unchanged, but wrong images are captured during accidents
Solution Approach 1:
The system uses sensors (acceleration sensor, gyro sensor) to continuously monitor the actual position and posture of the black box and camera. The controller compares the detected position with the predetermined normal position and provides feedback to the user when deviation is detected, enabling real-time verification and correction of installation accuracy without requiring complex manufacturing processes.
Solution Approach 2:
The patent establishes a predetermined normal position for the black box and camera before installation occurs. By pre-defining the correct installation parameters and using sensors to detect deviations from these predetermined values, the system guides proper installation beforehand rather than requiring post-installation calibration, simplifying the manufacturing and installation process while ensuring position accuracy.
3Measurement precision
If multiple sensors and data processing are added to determine vehicle posture accurately, then the measurement precision improves, but the device complexity increases
Solution Approach 1:
The controller serves multiple functions: it processes data from acceleration sensors, gyro sensors, and cameras; determines vehicle posture; detects accident conditions; and provides user guidance. By making the controller a multi-functional component that handles diverse tasks, the patent avoids adding separate dedicated devices for each function, thereby improving measurement precision while limiting the increase in overall system complexity.

AI summary
A vehicle navigation of the present invention comprises: a storage unit which stores normal posture data of a vehicle black box; a communication unit which communicates with the vehicle black box; and a controller which obtains current posture data by analyzing data received from the vehicle black box, and determines whether the stored normal posture data is matched with the obtained current posture data. According to the present invention, the driver is notified in advance that the position of a camera is out of shape due to the repeated vibration or acceleration or the like of a vehicle. Thus, the driver can correct the vehicle black box, the camera equipped in the vehicle black box or the camera provided in the vehicle to the normal positions.
