Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Display apparatuses risk collision with the floor during pivot rotation due to insufficient spacing, potentially causing damage.
Innovation Solution
A display apparatus with a support device that includes a support arm and stand, featuring a link member and cylinder to automatically move the display upward when rotated at a predetermined angle, preventing collision with the floor.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the display is positioned close to the floor surface, then the device footprint is minimized, but the display collides with the floor during pivot rotation
Solution Approach 1:
The support arm incorporates a cylinder mechanism that dynamically adjusts the vertical position of the display during pivot rotation. When rotation is detected, the cylinder extends to lift the display upward, maintaining clearance from the floor. This dynamic adjustment allows the display to be positioned close to the floor during normal use while preventing collision during rotation operations.
2Reliability
If the display is positioned far from the floor surface, then collision during rotation is prevented, but the device occupies more vertical space
Solution Approach 1:
Rather than maintaining a fixed elevated position, the support arm uses a cylinder mechanism to provide on-demand vertical adjustment. The display remains close to the floor during normal operation, and only elevates when rotation is detected. This dynamic approach prevents collision while minimizing vertical space occupation during stable operational states.
3Reliability
If automatic upward movement mechanism is added, then collision prevention is achieved, but device complexity increases
Solution Approach 1:
The support arm incorporates a cylinder mechanism that automatically detects when pivot rotation begins and autonomously extends to lift the display upward. This self-service mechanism eliminates the need for external control systems or manual intervention, achieving reliable collision prevention through integrated automatic operation.

AI summary
A display apparatus including a display; a support arm coupled to a rear of the display to support the display such that the display is rotatable with respect to the support arm, and including a link member configured to move forward and rearward based on the display being rotated with respect to the support arm; and a support stand configured to support the support arm such that the support arm is movable along a vertical direction, and including a cylinder operable to provide a driving force to move the support arm upward along the vertical direction, wherein, when the display is rotated with respect to the support arm, the link member moves rearward, which thereby causes the cylinder to be operated to provide the driving force to move the support arm upward along the vertical direction, and thereby move the display upward along the vertical direction.
