Rotating Display Collision Detection With Motor Feedback Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Rotatable display apparatuses face challenges in safely rotating without colliding with persons or objects, risking injury and damage due to the lack of effective collision detection and response mechanisms.
Innovation Solution
A display apparatus equipped with a motor, sensor, and processor that outputs driving signals to control rotation based on collision detection, stopping rotation and returning to a previous state when a collision is identified, using pulse signals and torque control to manage rotation speed and direction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the display apparatus rotates from horizontal to vertical state, then the display functionality is improved, but the risk of collision with persons or objects increases
Solution Approach 1:
The system performs preliminary collision detection before completing the rotation operation. The processor monitors the rotation process in advance and identifies potential collisions with persons or objects, allowing the system to take preventive action before the harmful effect occurs.
Solution Approach 2:
The processor continuously monitors rotation status and collision conditions during the rotation process, using feedback from the rotation state to determine whether to continue or stop the rotation operation, thereby preventing collisions while maintaining display functionality.
2Productivity
If the display apparatus continues rotation upon detecting an object, then the rotation operation is completed, but injury or damage may occur
Solution Approach 1:
The processor monitors rotation status and collision conditions in real-time, using feedback to determine whether to continue or stop rotation, ensuring both operational completion and safety.
Solution Approach 2:
The system applies preliminary anti-action by stopping the rotation operation when a collision is detected, preventing the harmful effect of injury or damage while maintaining the reliability of the rotation function.
3Reliability
If the display apparatus stops rotation when collision is detected, then safety is improved, but the rotation operation is interrupted
Solution Approach 1:
The system stops rotation when collision is detected to prevent injury or damage, applying preliminary anti-action to eliminate the harmful effect while preserving the safety of the rotation operation.
Solution Approach 2:
The processor uses feedback from collision detection to control the rotation operation, stopping when necessary to ensure safety while maintaining the overall functionality of the rotation feature.

AI summary
A display apparatus (100) includes: a display; a motor configured to rotate the display; a sensor (130) configured to sense rotation of the display; and a processor (180) configured to output a driving signal for rotating the display in a first direction to the motor (120) when an event for rotating the display from a first posture to a second posture occurs and output a driving signal for rotating the display in a second direction to the motor when it is identified that the display collides with an object on the basis of the driving signal output to the motor and a signal received from the sensor while the display rotates.
