Mobile Warning Triangle Lane Alignment Control

Solution Overview

Problem

Existing mobile warning triangles may deviate from their intended path while moving towards a point of warning, lacking effective sensors and control systems to maintain alignment with lane markings, which can reduce their effectiveness in alerting other vehicles to road obstructions.

Innovation Solution

A mobile warning triangle equipped with color-sensitive sensors, such as TCS3200 sensors, and a control system comprising modules for lane detection and direction correction, allowing it to adjust its path to stay aligned with lane markings and prevent deviation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If a mobile warning triangle moves autonomously towards a warning point without sensors and control systems, then the device complexity is reduced, but the warning triangle deviates from the correct path and loses reliability

Engineering Contradiction:
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

The control system continuously receives feedback from color-sensitive sensors about the position of lane markings relative to the warning triangle. This feedback loop enables real-time detection of deviations and automatic correction through motor-driven wheel adjustments, ensuring the warning triangle maintains alignment with the intended path throughout its autonomous movement.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The mobile warning triangle is equipped with an autonomous control system that enables it to self-correct its path without human intervention. The system independently detects lane marking positions, calculates deviations, and adjusts wheel angles to maintain proper alignment, allowing the device to service itself during autonomous operation.

Inventive Principle:
Principle #25Self-service

2Reliability

If color-sensitive sensors and control modules are added to the mobile warning triangle, then path alignment reliability is improved, but the device complexity increases

Engineering Contradiction:
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The system replaces manual placement operations with an automated control system that uses color-sensitive sensors to detect lane markings and motor-driven mechanisms to adjust wheel angles. This substitution of mechanical manual intervention with sensor-based automation improves path alignment reliability while managing complexity through integrated electronic control.

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

Solution Approach 2:

The control system integrates multiple functions into a unified platform: lane marking detection, deviation calculation, wheel angle control, and distance measurement all operate through a single microcontroller unit. This multi-functionality approach improves reliability through comprehensive path management while minimizing the increase in device complexity by consolidating control functions.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Measurement precision

If the mobile warning triangle uses lane departure detection systems with multiple sensors, then measurement precision of lane position is improved, but the use of energy increases

Engineering Contradiction:
Core Design Contradiction:
Measurement precisionVSUse of energy by moving object

Solution Approach 1:

The system uses color-sensitive sensors to detect lane markings with high precision, employing slightly more sensing capability than strictly necessary to ensure accurate lane position measurement. This partial excessive action in detection ensures reliable lane tracking while the system only activates correction mechanisms when actual deviations are detected, optimizing energy usage.

Inventive Principle:
Principle #16Partial or excessive action

Solution Approach 2:

The control system operates continuously to maintain lane alignment, with sensors constantly monitoring lane marking positions and the microcontroller continuously adjusting wheel angles as needed. This continuous operation ensures high measurement precision and path accuracy while energy consumption is optimized by only activating motor corrections when deviations are detected rather than operating at full power continuously.

Inventive Principle:
Principle #20Continuity of useful action

AI summary

A method for controlling a mobile warning triangle to move along a lane marking controls the mobile warning triangle to move forward and acquire color information of the lane marking detected by a first sensor and a second sensor of the mobile warning triangle when the mobile warning triangle is placed to allow the first sensor to detect the lane marking of the lane. The color information detected by the first sensor is recognized or not recognized as a color of the lane marking, if yes, controlling the mobile warning triangle to continue moving forward. If not recognized, determining whether the color information detected by the second sensor is the color of the lane marking and if yes, correcting a moving direction of the mobile warning triangle to a first direction by a first predetermined angle or repetitions of the predetermined angle to continue moving forward.
