Solution Overview

Problem

Existing wireless network technologies do not effectively facilitate the sharing of real-time road condition information among vehicles to optimize traffic flow and emergency response in ad hoc networks, leading to delays and inefficiencies.

Innovation Solution

An ad hoc wireless network system where vehicles act as nodes, equipped with transceivers, processors, memory, road information modules, and sensors, to establish temporary connections, share road information, and coordinate traffic flow plans, enabling vehicles to avoid obstructions and assist emergency responders.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If existing wireless network technologies are used for vehicle communication, then basic connectivity is achieved, but real-time road condition information sharing is ineffective leading to traffic delays

Engineering Contradiction:

Improveroad condition information sharing effectivenessVSAvoidtraffic flow delay

Core Design Contradiction:

Loss of informationVSLoss of time

Solution Approach 1:

The system performs preliminary actions by establishing ad hoc wireless network connections between vehicles before traffic congestion or emergencies occur. Vehicles proactively share road condition information, allowing the network to be ready and optimized for real-time information exchange when needed, preventing information loss and reducing traffic delays.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

Vehicles act as intermediary nodes in the ad hoc wireless network, relaying road condition information between other vehicles and emergency services. This intermediary role enables effective information sharing across the network, overcoming the limitations of existing direct communication technologies and reducing information loss.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Productivity

If vehicles establish temporary wireless connections to share information, then real-time communication is enabled, but network stability and connection reliability deteriorate due to vehicle movement

Engineering Contradiction:

Improvereal-time information sharing capabilityVSAvoidwireless connection stability

Core Design Contradiction:

ProductivityVSReliability

Solution Approach 1:

The ad hoc wireless network is designed to be dynamic, automatically adapting to vehicle movement and changing network conditions. The system dynamically establishes, maintains, and reconfigures connections between vehicles as they move, allowing real-time information sharing to continue despite the unstable environment, thus maintaining productivity while accepting the inherent reliability challenges of mobile networks.

Inventive Principle:

Principle #15Dynamics

3Adaptability or versatility

If multiple vehicles act as network nodes to share road information, then information coverage and emergency response capability improve, but system complexity increases

Engineering Contradiction:

Improveemergency response capabilityVSAvoidad hoc network system complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

Vehicles are equipped with multi-functional road information modules that can perform multiple roles: collecting road condition data, transmitting information to other vehicles, relaying messages to emergency services, and receiving traffic flow plans. This universality allows the system to achieve high adaptability and emergency response capability without proportionally increasing complexity, as each vehicle node handles multiple functions through integrated modules.

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

An ad hoc network may be established between vehicles using a wireless connection. The wireless network may be used for sending and receiving information about road conditions, such as average speed, a location and configuration of a road obstruction, images of an accident scene, and a traffic flow plan. The wireless network may also be used for communicating with emergency response vehicles in order to enable faster and more effective responses to accidents.
