Rotating Display Panel Obstacle Sensing for Collision Avoidance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Display apparatuses that rotate their panels to change orientation may collide with nearby objects due to lack of environmental obstacle detection, leading to potential damage and unsafe operation.
Innovation Solution
A display apparatus equipped with sensors to detect obstacles along its rotational path, a processor to control the rotation based on detected obstacles, and a driver to adjust the rotation angle and direction, ensuring the panel rotates safely by stopping or reversing when obstacles are detected within a predetermined distance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the display panel rotates automatically according to rotation events, then the display apparatus provides appropriate display environments for different situations, but collision with nearby objects may occur
Solution Approach 1:
The sensor detects obstacles in advance before the display panel begins rotation. The processor receives obstacle detection results and determines whether to allow rotation based on this preliminary information, preventing collision before it occurs
Solution Approach 2:
The sensor continuously monitors the rotating direction of the display panel and provides real-time feedback to the processor. Based on this feedback, the processor dynamically adjusts rotation control, stopping rotation when obstacles are detected and resuming when the path is clear
2Adaptability or versatility
If the display panel rotates to change orientation, then the usefulness of the display apparatus is improved, but safety is compromised due to lack of obstacle detection
Solution Approach 1:
The sensor performs preliminary obstacle detection along the rotation path before the display panel rotates. The processor uses this advance information to determine whether rotation is safe, ensuring both orientation flexibility and operational safety
Solution Approach 2:
The sensor acts as an intermediary between the display panel and obstacles, detecting obstacles and transmitting this information to the processor, which then mediates the rotation control to prevent collision
