Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobile warning triangles face challenges in maintaining a correct path while moving towards a point of placement, which can be time-consuming and pose safety hazards due to potential deviations from lane markings.
Innovation Solution
A mobile warning triangle equipped with three color-sensitive sensors and a control device that adjusts its direction based on real-time color information from these sensors to ensure alignment with lane markings, using predetermined angles and speeds for correction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the mobile warning triangle moves automatically towards the placement point, then the placement efficiency is improved, but the alignment accuracy with lane markings deteriorates due to potential path deviations
Solution Approach 1:
The patent employs sensors to detect lane marking positions in real-time and feeds this information back to the control device, which then adjusts the moving direction and speed to maintain accurate alignment with the lane markings throughout the movement process
Solution Approach 2:
The patent replaces manual mechanical placement with an automated control system that uses sensors and control algorithms to guide the mobile warning triangle's movement, substituting human operation with an intelligent control mechanism that maintains both efficiency and precision
2Manufacturing precision
If manual placement is used, then the alignment with lane markings is accurate, but the placement process is time-consuming and laborious
Solution Approach 1:
The mobile warning triangle performs self-alignment and self-placement through its integrated sensors and control system, automatically detecting lane markings and adjusting its own movement without requiring manual intervention, thus reducing both time and labor while maintaining accuracy
3Productivity
If the mobile warning triangle moves at higher speed, then the placement efficiency is improved, but the safety hazards increase due to potential deviations from correct path
Solution Approach 1:
The control system continuously monitors the mobile warning triangle's position relative to lane markings through sensors and provides real-time feedback to adjust movement parameters, enabling safe high-speed operation by actively correcting any path deviations that could lead to safety hazards
4Object-affected harmful factors
If the mobile warning triangle moves slowly, then the safety is improved, but the placement efficiency deteriorates due to extended placement time
Solution Approach 1:
The patent implements dynamic speed adjustment where the mobile warning triangle operates at higher speeds when alignment is confirmed and reduces speed when approaching placement points or encountering complex lane conditions, optimizing both safety and efficiency throughout the movement process

AI summary
A method for controlling the motion of a mobile warning triangle for placement behind a stationary vehicle on a roadway acquires color information of the lane markings detected by a first sensor, a second sensor, and a third sensor of the mobile warning triangle. When the mobile warning triangle is placed on the roadway, the first to third sensors are preset in position to detect the lane markings and their colors. The white or yellow color information of the lane markings or of the black-colored roadway are detected or not detected on an individual basis by the sensors and deviations from a required path are recognized when different colors are received in certain combinations by the sensors. If no deviation is recognized in the colors, the mobile warning triangle is controlled to continue moving forward.
