Solution Overview
Problem
Current mobile warning triangles cannot adjust their speed according to the slope of a road, which may lead to stalling on uphill roads or losing direction on downhill roads, compromising their effectiveness in warning other vehicles.
Innovation Solution
A mobile warning triangle equipped with a control system that includes a detector (e.g., accelerometer) and a processor to determine the road slope, adjusting its movement speed via a motor controller to maintain a predetermined speed, ensuring stable operation on varying terrain.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a mobile warning triangle moves at a constant speed without adjustment, then the device structure remains simple, but the triangle will stall on uphill roads or lose direction on downhill roads
Solution Approach 1:
The mobile warning triangle employs a dynamic speed control mechanism that automatically adjusts movement speed based on real-time detection of road slope conditions. The control system receives slope information from sensors and dynamically modifies motor output to maintain constant velocity, transforming a static constant-speed design into an adaptive dynamic system that responds to environmental variations.
Solution Approach 2:
The system implements a closed-loop feedback control mechanism where sensors continuously detect road slope conditions and feed this information to the control unit. The control unit processes the slope data and adjusts the motor speed accordingly, creating a feedback loop that ensures the warning triangle maintains its predetermined speed regardless of uphill or downhill terrain variations.
2Manufacturing precision
If the mobile warning triangle uses a detector and processor to determine road slope, then speed adjustment accuracy improves, but the device complexity increases
Solution Approach 1:
The system replaces manual speed adjustment mechanisms with an automated electronic control system. Instead of mechanical levers or switches for speed control, the invention uses electronic sensors to detect slope and an electronic control unit to automatically regulate motor speed, achieving precise speed maintenance without manual intervention.
Solution Approach 2:
The control system dynamically changes the operational parameter of motor speed based on detected road slope conditions. By monitoring slope angle variations and相应ly adjusting the motor's rotational speed parameter, the system maintains constant forward velocity of the warning triangle despite changes in terrain gradient.

AI summary
A control system for maintaining a traffic warning triangle at a constant speed when deployed, notwithstanding rises and falls in the road surface, includes a driver, a driving controller, a detector, and a processor. The driving controller controls the driver to drive the mobile warning triangle to move on a road at a predetermined speed. The detector obtains information as to the road. The processor outputs control signals to the driving controller to control the mobile warning triangle to move at the constant predetermined speed when moving. A control method of the mobile warning triangle is also provided.
