Solution Overview
Problem
Conventional pivotable display apparatuses often collide with obstacles during pivoting, causing user disorientation and potential damage due to unknown obstruction sources.
Innovation Solution
A display apparatus equipped with sensors and a processor that identifies obstructions, displays a user interface guiding safe pivoting directions, and controls the pivoting speed to prevent damage, including manual and automatic modes for user intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the display apparatus is equipped with remote pivoting control capability, then the user can adjust the screen angle conveniently, but the display apparatus may collide with obstacles during pivoting causing damage and user disorientation
Solution Approach 1:
The system performs preliminary detection of obstacles on the pivoting path before the pivoting action is executed. The sensor detects obstacles in advance, and the processor receives this detection result before controlling the pivoting driver to move the display panel, allowing the system to prepare appropriate responses (such as warning the user or adjusting pivoting parameters) to prevent collisions.
Solution Approach 2:
The system implements a feedback mechanism where sensors continuously monitor the pivoting environment and provide real-time information to the processor. When an obstacle is detected during pivoting, the sensor sends a signal to the processor, which then adjusts the pivoting control accordingly (such as stopping or reversing the pivoting motion), creating a closed-loop control system that prevents collisions.
2Ease of operation
If the display apparatus pivots automatically without user guidance, then the pivoting operation is simplified, but the user cannot understand the cause of obstruction or take appropriate action
Solution Approach 1:
The system provides feedback to the user about the pivoting status and any obstacles detected. The processor controls the display to show a user interface that includes information about the obstruction, such as the position and nature of the obstacle, allowing the user to understand what is preventing smooth pivoting and take appropriate action.
Solution Approach 2:
The system introduces an intermediary information layer between the automatic pivoting control and the user. The processor acts as an intermediary that not only controls the pivoting driver but also processes sensor data and presents it to the user through the display interface, bridging the gap between automatic operation and user awareness.
3Speed
If the pivoting speed is increased to improve responsiveness, then the pivoting operation is faster, but the risk of collision and damage increases
Solution Approach 1:
The system dynamically adjusts the pivoting speed based on real-time obstacle detection results. The processor controls the pivoting driver to operate at different speeds depending on the situation: faster speed when the path is clear, and slower or stopped speed when obstacles are detected. This dynamic speed adjustment maintains responsiveness while preventing collisions.
Solution Approach 2:
The system changes the operational parameters of the pivoting driver based on sensor feedback. When an obstacle is detected, the processor modifies parameters such as pivoting speed and acceleration, controlling the pivoting driver to slow down or stop, thereby preventing collision damage while maintaining efficient operation under normal conditions.
