Rotating Display Mount for Precise Landscape-Portrait Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current digital signage systems, particularly double-sided ones, lack the ability to switch between landscape-screen and portrait-screen modes via rotation, limiting adaptability and content display effectiveness.
Innovation Solution
A display apparatus with a support and rotation mechanism that includes a pivotable rotation part connected to the display module, allowing it to switch between landscape-screen and portrait-screen modes by controlling the included angle between the rotation axis and the frame segments, enabling smooth transitions without deviation and easy maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a double-sided digital signage uses fixed landscape or portrait orientation, then the structure is simple, but the adaptability to different display scenarios is poor
Solution Approach 1:
The support structure incorporates a rotation mechanism that allows the display module to dynamically change orientation between landscape and portrait modes. The rotation part includes a movable sleeve that can rotate relative to the support sleeve, enabling the display to adapt to different display scenarios without requiring multiple fixed installations.
2Manufacturing precision
If the rotation axis is aligned with the frame segment, then the mounting is simple, but the switching between landscape and portrait modes produces deviation
Solution Approach 1:
The rotation axis is deliberately designed to be offset from the frame segment by a specific included angle (45 degrees). This asymmetric arrangement allows the display module to switch precisely between landscape and portrait modes without deviation, as the angled connection points enable exact 90-degree orientation changes while maintaining simple mounting through the standardized rotation interface.
3Adaptability or versatility
If the included angle between rotation axis and frame segment is large, then the mode switching range is sufficient, but the mounting becomes complex
Solution Approach 1:
The included angle between the rotation axis and frame segment is optimized to 45 degrees, which provides the necessary mode switching capability while keeping the connection structure simple. This specific angular parameter enables precise landscape-portrait transitions without requiring complex mounting arrangements, balancing adaptability with structural simplicity.
