Rotating Display Stand Structure for Rattle-Free Orientation Change
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display stands for large devices, such as interactive whiteboards and electronic blackboards, are unstable when rotated, leading to rattling issues, especially when users apply load through writing or other forces.
Innovation Solution
A rotatable stand system with a rotating unit that includes a fixed part and a moving part, utilizing a large spacer and small spacers to maintain contact and stability across multiple holes, preventing rattling by ensuring continuous surface contact and support during orientation changes from landscape to portrait and vice versa.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If an optional rotating unit is added to allow manual rotation of the display device, then the display device can be changed between portrait and landscape orientations, but the display device becomes unstable and rattling occurs when load is applied
Solution Approach 1:
The rotating unit is divided into a fixed part and a moving part, with the moving part further segmented into multiple supporting posts that can independently contact the sliding plate at different positions. This segmentation allows the structure to adapt to orientation changes while maintaining stability through distributed contact points.
Solution Approach 2:
The rotating unit employs a dynamic structure where the moving part can rotate relative to the fixed part, and the supporting posts can dynamically adjust their positions to maintain contact with the sliding plate during rotation. This dynamic adaptability ensures stability throughout the orientation change process.
2Ease of operation
If a rotating unit is provided as a separate option, then users can manually change display orientation, but rattling occurs when users write on the display device
Solution Approach 1:
The rotating unit is integrated into the stand mechanism rather than being a completely separate component. The moving part of the rotating unit merges with the stand's supporting structure, creating a unified system where the supporting posts work together with the stand mechanism to eliminate rattling while preserving manual rotation capability.
3Adaptability or versatility
If the display device is rotated between portrait and landscape orientations, then orientation versatility is improved, but stability deteriorates due to the optional rotating unit configuration
Solution Approach 1:
The moving part of the rotating unit acts as an intermediary between the fixed stand mechanism and the rotatable display device. This intermediary component with its multiple supporting posts provides a stable transition mechanism that maintains overall system stability while enabling orientation changes.
