Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a technology that can analyze dangerous driving behaviors of two-wheeled vehicles using big data and automatically generate warning messages to remind drivers of potential hazards, as existing methods fail to effectively address the safety concerns and efficiency of road usage.
Innovation Solution
A warning system comprising sensing apparatuses and a server that collects and analyzes driving trajectories, generates an accident hotspot list by identifying clusters of dangerous driving behavior events, and sends warning messages to drivers when their trajectory matches a hotspot location or if their driving evaluation score is below a threshold.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If sensing apparatuses and big data analysis are used to monitor and analyze driving trajectories, then accident prevention capability is improved, but system complexity and cost increase
Solution Approach 1:
The patent introduces a server as an intermediary component that centralizes the complex tasks of trajectory analysis, accident hotspot identification, and warning message generation. The sensing apparatuses only need to collect basic trajectory data and communicate with the server, while all complex processing is performed remotely. This mediator approach allows the system to achieve high accident prevention capability without significantly increasing the complexity of individual vehicle components.
2Reliability
If real-time trajectory monitoring and analysis are implemented, then driving safety is improved, but energy consumption and data transmission burden increase
Solution Approach 1:
The system implements periodic action by sending trajectory data at specific time intervals rather than continuously transmitting data. The server receives trajectory information periodically, processes it to identify dangerous driving behaviors, and generates warning messages when necessary. This periodic approach maintains real-time monitoring capabilities while significantly reducing energy consumption and data transmission burden compared to continuous monitoring.
3Measurement precision
If multiple sensing apparatuses are deployed to collect comprehensive driving data, then measurement precision is improved, but device complexity and cost increase
Solution Approach 1:
The patent merges the functions of multiple sensing apparatuses into a unified server-based processing system. Instead of requiring each vehicle to have complex onboard analysis capabilities, the system combines data collection from multiple vehicles and performs centralized analysis on the server. This merging approach achieves high measurement precision for detecting dangerous driving behaviors while avoiding the need for each individual vehicle to carry complex sensing and processing equipment.
