Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Off-road vehicle operators face challenges in detecting the proximity of other vehicles in remote environments with limited or no cellular coverage, leading to increased collision risks due to restricted visibility and lack of effective communication systems.
Innovation Solution
A system of devices equipped with sensors and wireless technologies, such as RF and GPS, that detect the presence and proximity of other devices, generating alerts via tactile, audio, or visual means without relying on cellular networks, allowing users to avoid collisions in remote areas.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If cellular networks are used for communication between off-road vehicles, then communication reliability is improved, but the system becomes inoperative in remote areas without cellular coverage
Solution Approach 1:
The patent introduces a mesh network as an intermediary communication system that operates independently of cellular infrastructure. Devices communicate directly with each other through wireless mesh networking, creating a self-contained communication network that functions in remote areas without requiring cellular towers or external infrastructure.
Solution Approach 2:
The communication system is segmented into independent device-to-device communication units rather than relying on a centralized cellular network. Each device acts as an autonomous node in the mesh network, enabling communication to continue even when individual devices are out of range of others, thus maintaining operability in remote environments.
2Reliability
If proximity detection systems are implemented to reduce collision risks, then safety is improved, but device complexity increases
Solution Approach 1:
The patent integrates multiple functions into a single device: proximity detection, wireless communication, alert generation, and navigation assistance are all combined in one portable unit. This multi-functionality reduces the need for separate specialized devices while maintaining comprehensive safety capabilities.
Solution Approach 2:
The system automatically detects proximity of other vehicles and generates alerts without requiring manual operation. The devices self-configure into mesh networks, automatically route communications, and provide navigation assistance based on real-time position data, reducing the operational burden on users while enhancing safety.
