Display Mount Assembly With Auto-Swivel Viewing Position
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing retractable wall mounts for displays, such as TVs, require manual adjustment of the azimuth angle after extension, which is inconvenient, especially when the retraction/extension function is automated and remote-controlled.
Innovation Solution
A mounting device with a mechanism that automatically adjusts the azimuth of a display to a pre-set position when lowered, using a set screw and biasing spring, and includes a motorized actuator for vertical movement, allowing the display to swivel horizontally and move up or down relative to the wall.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a swiveling mechanism is included to allow convenient watching from angles, then viewing convenience is improved, but the device complexity increases and manual adjustment is required
Solution Approach 1:
The biasing spring mechanism automatically adjusts the azimuth angle of the display when it is lowered to a viewing position, eliminating the need for manual user adjustment. The spring is configured to engage with the swiveling mechanism and automatically rotate the display to a predetermined optimal viewing angle, making the system self-adjusting rather than requiring user intervention.
Solution Approach 2:
The biasing spring is pre-configured to exert a specific torque that automatically positions the display at the desired azimuth angle before the user even looks at it. This preliminary automatic adjustment happens as part of the lowering action itself, so the display is already optimally positioned when it reaches the viewing height, eliminating the need for subsequent manual adjustments.
2Ease of operation
If the retraction/extension function is automated and remote-controlled, then ease of operation is improved, but the loss of time for adjustment increases due to manual azimuth adjustment
Solution Approach 1:
The automatic azimuth adjustment mechanism using the biasing spring operates simultaneously with the motorized retraction/extension, so while the display is being lowered or extended, the spring automatically positions it at the correct angle. This eliminates the additional time that would otherwise be required for manual azimuth adjustment after the display reaches its position.
Solution Approach 2:
The biasing spring mechanism ensures that the azimuth adjustment is a continuous action that occurs throughout the lowering or extending process, rather than a separate discrete adjustment step. The spring continuously exerts torque to rotate the display as it moves, so the adjustment is integrated into the main movement, eliminating idle adjustment time.
3Adaptability or versatility
If the display is allowed to swivel horizontally for viewing convenience, then viewing flexibility is improved, but the risk of the display crashing into the wall increases
Solution Approach 1:
The biasing spring is pre-configured to automatically position the display at a specific azimuth angle that optimizes viewing flexibility while maintaining a safe distance from the wall. This predetermined angle is calculated to provide adequate viewing angles without allowing the display to swivel far enough to collide with the wall, thus preventing harmful collisions before they can occur.
Solution Approach 2:
The biasing spring mechanism provides mechanical feedback that limits the maximum azimuth angle the display can reach. As the display approaches the predetermined safe angle, the spring's torque naturally decreases, preventing further rotation that would bring the display too close to the wall, thus providing passive feedback-based collision prevention.

AI summary
A device for wall mounting a display including a mount assembly and a swivel mechanism assembly. The mount assembly includes a television mounting portion and an extending/contracting portion and the swivel mechanism assembly moveable between a first and a second configuration and including a biasing component. The extending/contracting portion includes a lower arm, an upper arm, a front bracket, a wall mounting bracket, one or more gas springs, and a linear actuator. The one or more gas springs and the linear actuator may lower and raise the television mounting portion. The biasing component is configured to bias the television mounting portion to swivel in a first or a second direction when the swivel mechanism assembly is in the first configuration when the display mounting portion is lowered. The mount assembly may include a set screw to set a swivel stop for the first and the second swivel directions.
