Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional display device turning bases for thin-screen display devices, such as liquid crystal displays, face instability due to an unfixed gravity center, leading to variable rotation speed and inability to stably turn the device backward and forward.
Innovation Solution
The solution involves a base with arc guide rails positioned to maintain the gravity center of the display device fixed, supported by rollers and an electric drive mechanism that turns these rails to stabilize and smoothly rotate the device, ensuring consistent rotation speed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional turning base configuration is used with a support portion protruding forward, then the display device can be turned by hand, but the gravity center position is not fixed causing instability during electric turning
Solution Approach 1:
The patent uses arc-shaped guide rails with a specific curvature radius instead of straight guide rails. The arc guide rails are positioned such that their center point lies on a horizontal line passing through the gravity center of the display device, creating a spherical motion path that keeps the gravity center fixed during rotation. This curved geometry enables stable electric turning while maintaining manual operability.
Solution Approach 2:
The patent positions the arc guide rails such that the center point of the arc lies on the horizontal line passing through the gravity center of the display device. This creates an equipotential configuration where the gravity center remains at a constant height and position relative to the rotation axis during turning, eliminating gravitational instability and enabling smooth electric rotation.
2Adaptability or versatility
If the gravity center position is not fixed, then manual turning is possible, but rotation moment changes causing variable rotation speed and unstable turning
Solution Approach 1:
The patent positions the arc guide rails such that the center point of the arc lies on the horizontal line passing through the gravity center of the display device. This creates an equipotential configuration where the gravity center remains at a constant height and position relative to the rotation axis during turning, eliminating gravitational instability and enabling smooth electric rotation.
