Solution Overview

Problem

Current traffic control systems rely on visual signals that are dependent on driver awareness, leading to inefficiencies in traffic flow and safety, especially in congested areas where accurate information about future traffic conditions is lacking.

Innovation Solution

A traffic control system comprising wireless transceivers in traffic signals and vehicles that enable vehicle-to-vehicle and vehicle-to-traffic signal communication, allowing for the transmission and reception of messages regarding speed, direction, and other critical information to optimize traffic flow and safety.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If visual signals (turn signals, brake lights) are used for vehicle communication, then driver awareness and visual confirmation are maintained, but traffic flow efficiency deteriorates due to dependence on constant driver attention and reaction time

Engineering Contradiction:

Improvedriver awarenessVSAvoidtraffic flow efficiency

Core Design Contradiction:

ReliabilityVSProductivity

Solution Approach 1:

The patent replaces the mechanical/visual signal system (brake lights, turn signals) with an electronic wireless communication system. Vehicles equipped with transceivers automatically exchange data about speed, position, and direction without requiring driver visual confirmation, thereby maintaining reliability while dramatically improving traffic flow efficiency.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent introduces wireless transceivers as intermediaries between vehicles and between vehicles and traffic signals. These intermediaries automatically transmit and receive communication data, eliminating the need for direct driver-to-driver visual monitoring and enabling more efficient traffic coordination.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Loss of information

If current traffic information systems provide real-time congestion data to drivers, then some traffic awareness is improved, but accurate prediction of future traffic conditions deteriorates due to lack of predictive modeling capability

Engineering Contradiction:

Improvetraffic information accuracyVSAvoidfuture traffic condition prediction

Core Design Contradiction:

Loss of informationVSLoss of time

Solution Approach 1:

The patent implements predictive modeling that performs preliminary analysis of traffic patterns using current vehicle location and destination data. By predicting future traffic conditions before they occur, the system allows drivers to make proactive routing decisions rather than reacting to current congestion, thereby reducing future traffic problems.

Inventive Principle:

Principle #10Preliminary action

3Productivity

If wireless transceivers are installed in traffic signals and vehicles for direct communication, then traffic flow optimization and safety are improved through real-time data exchange, but system complexity increases due to multiple communication components and protocols

Engineering Contradiction:

Improvetraffic flow optimizationVSAvoidcommunication system complexity

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The patent designs the wireless transceiver system to perform multiple functions: vehicle-to-vehicle communication, vehicle-to-tradiction signal communication, and data exchange for both traffic flow optimization and safety monitoring. This multi-functionality reduces the need for separate specialized systems, thereby managing complexity while achieving multiple goals.

Inventive Principle:

Principle #6Universality (Multi-functionality)

4Reliability

If drivers rely on visual confirmation of signals from vehicles ahead, then proper separation between vehicles is maintained, but reaction time increases due to the time required for visual detection and processing

Engineering Contradiction:

Improvevehicle separation maintenanceVSAvoiddriver reaction time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The patent implements automatic feedback loops where vehicles continuously transmit their status (speed, position, braking state) via wireless communication. Following vehicles receive this feedback instantly and can automatically adjust their speed and position, maintaining proper separation without the delay inherent in visual detection and human reaction.

Inventive Principle:

Principle #23Feedback
