Display Stand Extraction Hinge Mechanism for Natural Viewing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display stands for flat type displays, such as liquid crystal displays, often result in unnatural viewing postures and stability issues when the display is set in a horizontal state, leading to difficulties in input operations and safety concerns due to the increased height and protrusion of the stand components.
Innovation Solution
A display stand design featuring a base member with side surface sections, front and back end sections, and arm sections with specific hinge connections that allow the display to be adjusted to various angles without the arm sections being interposed between the display and the base, enabling the display to be positioned closer to the user while maintaining stability, even when the lower end protrudes beyond the desk surface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If link members or arm sections are interposed between the display and base to enable inclination adjustment, then the display can be adjusted to various angles, but the height from desk surface to display screen becomes large, causing unnatural viewing posture
Solution Approach 1:
The patent removes the arm sections from between the display and base when the display is in horizontal state. The arm sections are extracted from the support path, allowing the display to be positioned closer to the user while maintaining stability through direct contact between the display lower end and base member.
2Adaptability or versatility
If the display is laid flat in horizontal state to enable detailed viewing, then the viewer can peer into the display from above, but the arm sections and hinge sections increase the height, making the viewing operation unnatural
Solution Approach 1:
The arm sections are removed from the support structure when the display is in horizontal state, extracting the height-increasing components. This allows the display to be positioned at a lower, more natural height for overhead viewing while maintaining stability.
3Ease of operation
If the lower end section of display screen protrudes from desk surface to bring display closer to user, then input operations become easier, but the stand stability is compromised
Solution Approach 1:
The patent positions the center of gravity of the entire stand system (including display and base) at a location that ensures stability. By carefully designing the mass distribution and geometric parameters, the system achieves equipotential stability even when the display lower end protrudes from the desk surface, preventing the stand from tipping over.
4Adaptability or versatility
If hinge sections and link members are used to support the display, then the display can be adjusted to various positions, but the device complexity increases
Solution Approach 1:
The patent removes the arm sections and reduces the number of hinge sections needed. By eliminating the intermediate arm sections, the structure is simplified while still maintaining the capability to adjust the display to various positions and angles, particularly in both upright and horizontal states.
