Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Mobile warning triangles sent out towards a point of placement and in motion may deviate from a correct path, failing to effectively warn other vehicles of obstructions due to difficulties in maintaining alignment with lane markings.

Innovation Solution

A mobile warning triangle equipped with a color-sensitive sensor, such as the TCS3200, and a control device that includes modules for detecting lane markings, correcting deviations, and controlling movement to ensure accurate placement and alignment along the road.

Engineering Contradictions & Design Principles

1Productivity

If mobile warning triangle moves autonomously towards placement point, then placement efficiency is improved, but path alignment accuracy deteriorates due to deviation from correct path

Engineering Contradiction:

Improveplacement efficiencyVSAvoidpath alignment accuracy

Core Design Contradiction:

ProductivityVSManufacturing precision

Solution Approach 1:

The patent implements a feedback control system where sensors continuously detect lane marking positions and the control unit adjusts the warning triangle's movement in real-time to maintain alignment with the lane marking, resolving the contradiction between autonomous movement efficiency and path alignment accuracy

Inventive Principle:

AI summary

A method for controlling the motion of a mobile warning triangle for suitable placement on a roadway acquires information as to color of the lane markings detected by a sensor. When the mobile warning triangle is first placed on the roadway, the sensor is preset in position to detect the lane marking. White or yellow color information of the lane marking or of the black-colored roadway are detected or are not detected by the sensor, and deviations from a required path are recognized when different colors are received in certain combinations by the sensor. If no deviation is recognized in the colors, the mobile warning triangle continues moving forward. If a deviation in colors is recognized, the mobile warning triangle is controlled to hunt to the left and right through one or more predetermined angles to try to detect or redetect the lane marking.
