Solution Overview

Problem

Drivers face challenges in obtaining sufficient information about vehicles ahead, especially in scenarios with limited visibility, such as curves or mountain roads, leading to potential traffic accidents due to the need for deceleration or stopping.

Innovation Solution

A road screen networking system comprising multiple road screen units that acquire and transmit vehicle information within their communication range, including identification codes and speeds, to vehicle-mounted units, enabling improved visibility and reducing the risk of accidents.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If drivers rely on direct visual recognition of vehicles ahead, then driving safety can be ensured when visibility is good, but driving safety deteriorates when visibility is limited (curves or mountain roads)

Engineering Contradiction:

Improvedriving safetyVSAvoidfront vehicle information

Core Design Contradiction:

ReliabilityVSLoss of information

Solution Approach 1:

The patent introduces road screen units as intermediary devices that capture images of vehicles ahead and transmit this information to drivers through display screens. This intermediary system bridges the information gap when direct visual recognition is blocked by curves or mountain roads, allowing drivers to see front vehicle information without direct line of sight.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent replaces the mechanical/physical system of direct human visual recognition with an electronic information transmission system. Cameras mounted on road screens capture vehicle images, which are then processed and displayed electronically, substituting the need for direct optical line of sight between driver and front vehicle.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Reliability

If drivers decelerate or stop to confirm front vehicle information, then driving safety is improved, but traffic efficiency deteriorates due to rear-end collisions and disruption to rear vehicles

Engineering Contradiction:

Improvedriving safetyVSAvoidtraffic efficiency

Core Design Contradiction:

ReliabilityVSProductivity

Solution Approach 1:

The patent provides front vehicle information to drivers in advance through road screen displays, allowing drivers to maintain their current speed and trajectory without needing to decelerate or stop. This preliminary information delivery eliminates the need for reactive speed adjustments that would disrupt traffic flow.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system establishes a feedback loop where road screen units continuously monitor and transmit front vehicle information to drivers, enabling informed decision-making about speed and positioning. This real-time feedback allows drivers to maintain optimal speed without compromising safety, thereby preserving traffic efficiency.

Inventive Principle:

Principle #23Feedback
