Moving-Entity Collision Detection via Cloud Position Sharing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Many car accidents occur due to drivers not perceiving potential collision partners hidden by visual obstacles, leading to insufficient time for spatial avoidance.
Innovation Solution
A method using a source device associated with a first entity to wirelessly transmit exploration messages to a cloud server, which then relays disclosure messages to the source device when target entities are within a defined sector and distance, enabling early spatial avoidance by displaying positions or adjusting the first entity's path.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If visual perception is used to detect collision partners, then the detection method is simple and direct, but visual obstacles can hide collision partners leading to late detection and insufficient response time
Solution Approach 1:
The patent introduces wireless communication devices and a cloud server as intermediaries between moving entities. These intermediaries transmit position and movement data, enabling entities to perceive each other's location and trajectory without direct visual contact, thereby overcoming obstacles that block line-of-sight detection
Solution Approach 2:
The system performs preliminary detection and tracking of moving entities by continuously transmitting and updating position data before potential collisions occur. This advance awareness allows entities to plan avoidance maneuvers in advance rather than reacting at the last moment
2Device complexity
If direct device-to-device communication is used between source device and target device, then the communication path is direct and simple, but the system complexity increases and scalability decreases
Solution Approach 1:
The cloud server acts as a central intermediary that collects data from multiple source devices and distributes relevant information to appropriate target devices. This centralized architecture simplifies individual device complexity while maintaining system-wide detection reliability through coordinated information sharing
Solution Approach 2:
The cloud server provides universal service to multiple entities simultaneously, handling data collection, processing, and distribution for numerous source and target devices. This multi-functional platform approach reduces individual device complexity while maintaining scalable system reliability
