Pivoting Display Stand Layout for Stable Portrait and Landscape Use
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices face challenges in maintaining stability at various installation angles, especially when transitioning between landscape and portrait orientations, leading to instability and difficulty in use.
Innovation Solution
A display device with a housing featuring a pivotable stand on its rear face, allowing for adjustable installation angles and enhanced stability in both orientations, utilizing a rotatable stand with a rectangular frame shape and elastic members for improved gripping, and a recessed design to manage cables and connectors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a built-in kickstand is provided to enable landscape and portrait orientations, then the degree of freedom of installation is increased, but stability at optimal viewing angles is difficult to achieve
Solution Approach 1:
The stand is designed to be rotatable about a rotation axis, allowing it to dynamically adjust between different orientations (landscape and portrait modes). This dynamic capability enables the display to adapt to different installation scenarios while maintaining stability through controlled rotational movement rather than fixed positioning.
Solution Approach 2:
The stand has an asymmetric width design where the width in the long-side direction is smaller than the width of the housing in the long-side direction. This asymmetric configuration optimizes the center of gravity distribution and contact area with the support surface, enhancing stability at optimal viewing angles while accommodating both landscape and portrait orientations.
2Area of stationary object
If the stand width in long-side direction equals housing width, then maximum support surface area is achieved, but the stand becomes too wide for portable use
Solution Approach 1:
The stand width is optimized locally rather than uniformly matching the housing width. By making the stand width in the long-side direction smaller than the housing width, the design creates an optimal balance between providing sufficient support surface area for stability and maintaining a compact profile for portability. This local optimization allows the stand to be wide enough for stability while remaining narrow enough for easy carrying.

AI summary
A display device (100; 100-2) includes a housing (110) having a rectangular shape in plan view, a display (121) having a screen surface exposed from a front face of the housing (110), and a stand (136; 136-2) disposed on a rear face of the housing (110) and pivotable on a rotation axis at a center in a short-side direction of the housing (110), to open and close relative to the housing (110). The stand (136; 136-2) has a width (W2) in a long-side direction of the housing (110) smaller than a width (W1) of the housing (110) in the long-side direction.
