Rotating Display Support Arm With Portrait Travel Limiting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Display modules in portrait orientation may collide with the floor surface due to a downward movement, as they have the same vertical movement range as in landscape orientation, potentially causing damage.
Innovation Solution
A display apparatus with a support device that limits the vertical movement range of the display module in portrait orientation, allowing different movement ranges based on the orientation, thereby preventing collisions with the floor.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the display module is allowed to move vertically within the same range in both landscape and portrait orientations, then the device structure is simple and easy to manufacture, but the display module may collide with the floor surface in portrait orientation causing damage
Solution Approach 1:
The support device dynamically adjusts the vertical movement range based on the display module's orientation. When rotated to portrait orientation, the limiting link engages with the limiting groove to reduce the vertical movement range, preventing floor collision. In landscape orientation, the full movement range is restored. This dynamic adaptation resolves the contradiction by making the structure context-dependent rather than fixed.
Solution Approach 2:
The limiting link is nested within the support arm structure, and the limiting groove is integrated into the support stand. The limiting protrusion on the limiting link fits into the limiting groove when needed, creating a compact nested arrangement that provides collision prevention without adding significant external complexity to the overall device structure.
2Reliability
If the vertical movement range is limited in portrait orientation, then the display module is protected from collision, but the device structure becomes more complex with additional limiting components
Solution Approach 1:
The limiting link serves multiple functions: it acts as a structural support element, a positioning mechanism, and a collision prevention device. The same component that supports the display module also contains the limiting protrusion that engages with the limiting groove. This multi-functionality reduces the need for separate protective components, simplifying manufacturing while ensuring protection.
Solution Approach 2:
The support device automatically adjusts its own configuration based on the display module's orientation without requiring external control systems. The limiting link self-engages or self-disengages from the limiting groove depending on the rotation position, making the system self-regulating and reducing the need for complex control mechanisms that would complicate manufacturing.
3Reliability
If the limiting link is positioned to engage the limiting groove in portrait orientation, then downward movement is restricted preventing floor collision, but the link must be movable laterally which increases mechanism complexity
Solution Approach 1:
The limiting link's lateral movement capability is merged with its vertical limiting function. The same lateral movability that allows the limiting protrusion to engage the limiting groove also enables the link to return to its original position. This combining of movement capabilities in a single component reduces the need for separate actuation mechanisms, simplifying the overall limiting mechanism while maintaining reliable movement restriction.

AI summary
A display apparatus is provided. The display apparatus includes: a display panel; a support bracket coupled to the display panel; a support arm coupled to the support bracket and supporting the display panel, wherein the support arm is configured to rotate between a first and second orientations; and a support stand supporting the support arm and defining a limiting groove, the support stand being configured to allow the support arm to move along a vertical direction. The support arm includes a limiting link configured to be in a first position that is offset from the limiting groove when the display panel is in the first orientation and a second position extending into the limiting groove when the display panel is in the second orientation.
