Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If black box devices are used to collect traffic accident information, then accident evidence can be recorded, but it is difficult to identify accident vehicle information in adverse conditions such as rain or at night
Solution Approach 1:
The patent combines multiple data sources including image data from black box devices, sensor data (acceleration, collision detection), and communication data from multiple vehicles into a unified accident determination system. This integration allows the system to overcome the limitations of individual black box devices by cross-referencing multiple data streams to identify accident vehicles accurately even in adverse conditions
Solution Approach 2:
The patent introduces a server as an intermediary that collects, processes, and analyzes data from multiple black box devices and vehicles. The server performs accident determination by comparing data from multiple sources and identifies accident vehicles based on correlated information, thereby overcoming the identification limitations of individual black box devices
2Speed
If multiple vehicles access the mobile communication system simultaneously to transmit accident information, then rapid information propagation is achieved, but communication congestion occurs due to system limits
Solution Approach 1:
The patent implements preliminary actions by having vehicles continuously transmit sensor data (acceleration, collision detection) and maintain communication readiness before accidents occur. When an accident is detected, the vehicle can immediately transmit critical information without waiting for system allocation, thereby achieving rapid information propagation while the server manages overall communication load to prevent congestion
3Ease of operation
If black box devices transmit image data without authentication, then data transmission is simple, but privacy invasion risks increase and data authenticity cannot be verified
Solution Approach 1:
The patent implements self-service authentication where each black box device automatically performs authentication and encryption operations without requiring manual intervention. The devices autonomously manage their own security credentials, sign their data transmissions, and encrypt sensitive information, thereby maintaining operational simplicity while ensuring data authenticity and privacy protection through cryptographic mechanisms
4Productivity
If accident information is collected without human intervention through device interaction, then collection efficiency is improved, but communication congestion increases due to lack of access control
Solution Approach 1:
The patent implements preliminary access control mechanisms where vehicles are pre-configured with authentication credentials and access parameters before joining the communication system. The server maintains pre-established rules for data transmission priorities and access permissions, allowing automated accident information collection to proceed efficiently while pre-defined control mechanisms prevent communication congestion and maintain system stability
Data Source
AI summary
Disclosed herein is a method for collecting, by a vehicle information collection apparatus, vehicle accident information. The method includes receiving vehicle accident information including impact detection time information and location information from a plurality of vehicle communication terminals, determining whether a vehicle accident has occurred based on the received vehicle accident information, requesting a vehicle communication terminal which belongs to the plurality of vehicle communication terminals and which is related to the vehicle accident to send accident information based on a result of the determination, receiving encrypted image data related to the vehicle accident from the vehicle communication terminal related to the vehicle accident in response to the request, and decoding the received image data and storing the decoded image data along with the vehicle accident information.
