Communication System Collision Warning via Server-Mediated Position Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobile communication devices and systems lack the capability to effectively address sudden changes in safety situations, such as accidents at blind intersections, where vehicles or pedestrians suddenly emerge from shadowy areas, leading to collisions.
Innovation Solution
A communication system comprising mobile and onboard communication devices that utilize position information obtained via GPS and a server to detect approaching vehicles or pedestrians within a predetermined range, triggering warnings through various means such as sound, vibration, or display to alert users of potential collisions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If position information is continuously transmitted and processed to detect approaching vehicles or pedestrians, then collision warning capability is improved, but communication system complexity and energy consumption increase
Solution Approach 1:
The patent introduces a server as an intermediary that receives position information from multiple communication devices, performs collision risk analysis, and sends warning signals back. This mediator approach allows complex processing to be distributed to the server rather than requiring each mobile device to independently analyze all position data, thereby improving collision warning capability while managing system complexity through centralized processing.
2Reliability
If position information is continuously obtained and transmitted to detect sudden changes in situation, then safety monitoring is improved, but energy consumption increases
Solution Approach 1:
The system performs preliminary actions by continuously obtaining and transmitting position information before actual collisions occur. The server analyzes these preliminary position data to predict potential collision risks and issues warnings in advance, allowing users to take preventive measures. This approach improves safety monitoring by maintaining continuous awareness of surrounding traffic conditions while enabling energy-efficient operation through predictive rather than reactive processing.
3Reliability
If warning processes are implemented for approaching objects, then collision prevention is improved, but device functionality complexity increases
Solution Approach 1:
The patent segments the collision prevention system into distinct functional modules: position information obtaining units in mobile devices, a central server for analysis and coordination, and warning units for output. This segmentation allows each component to perform its specific function efficiently without requiring every device to handle all aspects of collision prevention, thereby improving overall collision prevention capability while managing device functionality complexity through modular architecture.
