Solution Overview

Problem

Existing inspection devices for road surface monitoring struggle to accurately maintain a preset route, especially when lanes turn, requiring manual steering and affecting detection efficiency due to limited camera views and inability to automatically correct deviations.

Innovation Solution

An inspection device equipped with a control method that collects environment images, identifies lane lines, calculates deviations from a preset route, and adjusts its path to align with the route using cameras and image processing algorithms, allowing for automatic correction and steering.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If manual steering is used to maintain preset route, then route accuracy is improved, but operation complexity and time consumption increase

Engineering Contradiction:
Improveroute accuracyVSAvoidtime consumption
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The inspection device performs self-steering by automatically identifying lane lines through image processing and adjusting its own trajectory without external manual intervention. The device captures environment images, processes them to identify lane lines, calculates deviations from the preset route, and autonomously corrects its path, enabling the system to serve itself in maintaining route accuracy.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system implements a closed-loop feedback mechanism where the inspection device continuously monitors its position relative to the lane lines through image capture and processing, compares the actual position with the desired preset route, and automatically adjusts its trajectory based on the calculated deviation. This feedback loop eliminates the need for manual steering while maintaining high route accuracy.

Inventive Principle:
Principle #23Feedback

2Measurement precision

If manual steering is used to navigate lane turns, then route accuracy is improved, but ease of operation deteriorates

Engineering Contradiction:
Improveroute accuracyVSAvoidease of operation
Core Design Contradiction:
Measurement precisionVSEase of operation

Solution Approach 1:

The inspection device autonomously handles lane turn navigation by independently identifying lane line geometry, calculating deviation from the preset route, and executing self-steering corrections. The system processes environment images to detect lane line orientations and automatically adjusts its trajectory to follow lane turns without requiring manual intervention, thereby improving ease of operation while maintaining route accuracy.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent replaces manual mechanical steering operations with an automated image processing and control system. Instead of human operators manually controlling the device through lane turns, the system uses computer vision algorithms to identify lane lines, process their geometric features, and automatically generate steering commands, substituting mechanical manual control with an automated electronic control system.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

3Device complexity

If camera view is limited to current position, then device complexity is reduced, but measurement precision deteriorates

Engineering Contradiction:
Improvedevice complexityVSAvoiddetection accuracy
Core Design Contradiction:
Device complexityVSMeasurement precision

Solution Approach 1:

The image processing system performs preliminary identification and characterization of lane lines before the inspection device reaches the corresponding physical location. By capturing environment images ahead of time and processing them to identify lane line positions, orientations, and curvature, the system prepares navigation data in advance, enabling accurate route following without requiring complex real-time sensing at every moment.

Inventive Principle:
Principle #10Preliminary action
