Display Mount With Shifting Rotation Center for Balanced Reorientation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional display support systems make it cumbersome, hazardous, or require multiple adjustments to rotate large format displays between portrait and landscape orientations, disrupting user experience and limiting functionality due to the need to counterbalance gravitational torque during rotation.
Innovation Solution
A connection mechanism that enables rotation and translation of the display by shifting the center of rotation, using springs to counterbalance gravitational torque, and adjusting the position of tracks and rollers to minimize interference with pass-through cables and achieve a balanced feel throughout the rotation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the display is rotated between portrait and landscape orientations using a conventional fixed center of rotation, then the display can change orientation, but the gravitational torque varies significantly during rotation requiring multiple adjustments and creating hazardous conditions
Solution Approach 1:
The patent implements a dynamic center of rotation that shifts position during rotation from portrait to landscape orientation. The connection mechanism allows the center of rotation to move along an arc, enabling the display to rotate smoothly while maintaining a relatively constant gravitational torque profile, eliminating the need for multiple manual adjustments and reducing operational hazards
Solution Approach 2:
The patent employs spring elements configured to counterbalance the gravitational torque acting on the display during rotation. The springs are positioned and tensioned to provide opposing torque that compensates for the changing gravitational moment, creating a balanced rotation system that is safe and easy to operate
2Ease of operation
If springs are added to counterbalance gravitational torque, then the rotation becomes easier and safer, but the device complexity increases
Solution Approach 1:
The patent integrates the spring counterbalance mechanism directly into the connection structure that attaches the display to the mount. The connection mechanism combines both the rotational joint and the spring torque elements in a single integrated assembly, avoiding the need for separate counterbalance components and reducing overall device complexity
Solution Approach 2:
The patent resolves the torque balance problem by allowing the center of rotation to move along an arc (adding a positional dimension) rather than requiring complex multi-component mechanisms. This dimensional approach to the rotation path simplifies the overall structure while achieving smooth, balanced rotation

AI summary
A device for supporting an electronic display includes a support surface, a display mount configured to be coupled to a display, and a connection mechanism to connect the display mount to the support surface. The connection mechanism is configured to enable a rotation of the display mount between a first position and a second position. The device also includes a set of springs to provide a spring torque that counterbalances a gravitational torque exerted by the display. The connection mechanism causes a translation of the center point of the display relative to the support surface in concert with the rotation. The connection mechanism also causes the center of rotation of the display to shift during the rotation.
