Solution Overview

Problem

Existing vehicle systems lack an effective method to safely obstruct the path of a danger driving vehicle without risking human safety, as non-autonomous vehicles driven by humans can cause accidents when used for this purpose.

Innovation Solution

A vehicle path control apparatus and method that utilizes an unmanned vehicle to obstruct the path of a danger driving vehicle by selecting an appropriate unmanned vehicle based on road information, generating a driving path to intercept the danger vehicle, and controlling the unmanned vehicle to minimize damage and ensure safety, including calculating a danger driving score and notifying relevant parties.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If a non-autonomous vehicle driven by human intervention is used to obstruct a path of a danger driving vehicle, then the path obstruction function is achieved, but a personal accident may occur

Engineering Contradiction:

Improvepath obstruction capabilityVSAvoidsafety of obstruction operation

Core Design Contradiction:

ProductivityVSReliability

Solution Approach 1:

The vehicle performs path obstruction operations autonomously without human intervention during the critical obstruction phase. The autonomous vehicle independently navigates to the danger vehicle, executes the obstruction maneuver, and returns to base, eliminating the need for a human driver to be present in the vehicle during operation.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The human element is extracted from the obstruction operation. Instead of having a human driver control the vehicle during the dangerous obstruction maneuver, the control function is transferred to an autonomous system, separating the human operator from the high-risk operational context.

Inventive Principle:

Principle #2Taking out (Extraction)

2Reliability

If an autonomous vehicle is used to obstruct a path of a danger driving vehicle, then safety is improved by eliminating human intervention, but the complexity of the control system increases

Engineering Contradiction:

Improvesafety of obstruction operationVSAvoidcontrol system complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The autonomous vehicle is designed with multi-functionality, serving both as a regular transportation vehicle and as a path obstruction device. This universal design allows the same vehicle platform to perform multiple functions, reducing the need for specialized complex systems dedicated solely to obstruction operations.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The autonomous vehicle is pre-programmed with obstruction algorithms and pre-positioned at base locations near potential danger zones. The vehicle prepares in advance by receiving updates on danger vehicles and calculating optimal obstruction paths before actual obstruction events occur, reducing real-time computational complexity.

Inventive Principle:

Principle #10Preliminary action

3Productivity

If the unmanned vehicle is positioned to effectively obstruct the danger driving vehicle, then the obstruction effectiveness is improved, but the risk of collision and damage to the unmanned vehicle increases

Engineering Contradiction:

Improveobstruction effectivenessVSAvoiddamage to unmanned vehicle

Core Design Contradiction:

ProductivityVSObject-affected harmful factors

Solution Approach 1:

The autonomous vehicle performs a partial obstruction rather than a complete blockage. It positions itself to force the danger vehicle toward predetermined safe zones or exits rather than creating a head-on collision scenario, achieving the obstruction goal while minimizing direct contact and damage risk.

Inventive Principle:

Principle #16Partial or excessive action

Solution Approach 2:

The system pre-calculates multiple obstruction paths and selects routes that minimize potential damage to the autonomous vehicle. The vehicle is equipped with protective measures and the control system prioritizes paths that reduce the severity of any potential collisions, cushioning against the harmful effects before they occur.

Inventive Principle:

Principle #11Beforehand cushioning (Prior cushioning)
