Rotating Display Module Mechanism for Landscape-Portrait Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional display apparatuses are limited in providing various viewing modes, as they typically fix the screen orientation to a landscape mode, failing to accommodate user preferences for different viewing angles.
Innovation Solution
A display apparatus featuring a linearly-movable assembly and rotation guiding mechanism that allows the display module to rotate between landscape and portrait modes, enabled by a driver-powered screw bar and cam structure, facilitating easy switching between viewing modes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the screen orientation is fixed to landscape mode, then the device structure is simple, but the viewing mode versatility is limited
Solution Approach 1:
The display module is transformed from a fixed orientation to a dynamically adjustable orientation system. The display module can rotate between landscape and portrait modes through the rotation guiding mechanism, allowing the viewing orientation to change while maintaining structural integrity. This dynamic capability resolves the contradiction by enabling multiple viewing modes without requiring completely separate device structures.
Solution Approach 2:
The support assembly and rotation guiding mechanism serve multiple functions: they provide structural support, enable rotation between orientations, and allow for different installation modes (standing or wall-mounted). This multi-functionality achieves viewing mode versatility while avoiding the need for multiple separate structures, thus resolving the contradiction between adaptability and device complexity.
2Adaptability or versatility
If a rotation mechanism is added to enable mode switching, then the viewing mode versatility improves, but the device complexity increases
Solution Approach 1:
The rotation guiding mechanism is merged with the support assembly to form an integrated structure. The support assembly not only provides structural support but also incorporates the rotation guiding functionality, reducing the need for separate, complex rotation mechanisms. This merging approach enables mode switching while minimizing the increase in device complexity.
Solution Approach 2:
The linearly-movable assembly serves as an intermediary between the driver and the rotation guiding mechanism. It converts the driver's rotational motion into linear movement, which then actuates the cam structure to achieve display module rotation. This intermediary mechanism simplifies the overall system by providing a clear motion transformation path rather than requiring a complex direct rotation mechanism.
3Ease of operation
If the display module is made rotatable, then the ease of operation improves, but the manufacturing precision requirements increase
Solution Approach 1:
The cam structure in the rotation guiding mechanism provides self-aligning features that guide the display module into precise rotational positions (landscape and portrait modes) without requiring complex external alignment systems. The cam geometry inherently ensures proper alignment, reducing manufacturing precision requirements while maintaining ease of operation.
Solution Approach 2:
The patent replaces complex mechanical alignment systems with a cam-based mechanism that uses geometric constraints to achieve precise positioning. The cam structure converts linear motion from the linearly-movable assembly into controlled rotational movement, providing precise alignment through its geometric design rather than requiring high-precision mechanical components throughout the system.

AI summary
A display apparatus includes a display module displaying an image, a support assembly facing toward the display module, a driver installed on the support assembly for supplying power to rotate the display module, a linearly-movable assembly connected to the driver to receive power therefrom and configured to perform a linear movement in a first direction along the support assembly, and a rotation guiding mechanism that connects the linearly-movable assembly to the display module, and guides rotation of the display module using the movement of the linearly-movable assembly.
