Display Support Apparatus with Pivot Arms for Mobile Cart Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display supporting apparatuses for flat screen monitors are typically fixed to stationary structures, lacking the ability to be securely positioned and adjusted on mobile support structures, which can lead to accidental damage or injury during movement and increased risk of equipment tipping.
Innovation Solution
A display supporting apparatus with a base, first and second arms, and a display attachment bracket, featuring pivot mechanisms, a telescoping gas strut for counterbalancing, and a two-axis pivot joint, allowing for user-selected positioning and secure attachment to mobile carts, while preventing accidental movement and stabilizing the display during cart maneuvering.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the display supporting apparatus is fixed to a stationary structure, then the display is securely held in place, but the apparatus cannot be easily relocated or adjusted to different positions
Solution Approach 1:
The apparatus is divided into separable components: a base that can be detached from the support structure, arms that can be folded, and a display attachment bracket that can be removed from the display. This segmentation allows the apparatus to transition between a stable configured state for secure holding and a disassembled state for easy relocation, resolving the contradiction between security and relocatability.
2Stability of the object's composition
If the base is fixedly attached to the support structure, then the display is stable during use, but the position of the base cannot be adjusted relative to the support structure
Solution Approach 1:
The base incorporates a mounting mechanism with movable components that allow the base to be dynamically adjusted to different positions on the support structure. Once positioned, the base can be securely fixed. This dynamic capability enables both stable operation during use and easy repositioning when needed, resolving the contradiction between stability and adjustability.
3Adaptability or versatility
If the arms are made fully movable to allow position adjustment, then the display can be positioned anywhere, but the apparatus becomes unstable during movement
Solution Approach 1:
The apparatus includes damping mechanisms and friction elements that apply preliminary counteracting forces to prevent unintended movements of the arms. These mechanisms stabilize the arms during transport by counteracting gravitational and inertial forces, while still allowing deliberate position adjustments when needed. This resolves the contradiction between positioning flexibility and stability during movement.
4Reliability
If the display attachment bracket is permanently fixed to the display, then the connection is very secure, but the bracket cannot be removed or transferred to another display
Solution Approach 1:
The display attachment bracket incorporates a quick-release mechanism with pre-positioned locking elements and release levers. This preliminary arrangement of components allows the bracket to be rapidly and securely attached to and detached from displays without tools. The bracket maintains strong connection strength during use while enabling easy transfer between displays, resolving the contradiction between connection strength and transferability.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The apparatus securely holds the display in place on mobile carts, reduces the risk of damage or injury, and minimizes the likelihood of cart tipping by maintaining the display's center of mass within the cart's footprint, ensuring stable operation during movement.
Implementation Method 1
The second arm also includes a telescoping gas strut to counter balance the weight of the display so as to maintain the vertical position of the monitor as selected by the user. In addition, the gas strut dampens the up-and-down movement of the monitor to give the user better control when moving the display vertically.

AI summary
The display supporting apparatus includes a base, a first arm, a second arm, and a display attachment bracket designed to be fixedly securable or attachable to a display. The display support apparatus further includes a mechanism for providing a constant orientation in relation to the base for the plane bisecting the range of rotation of the second arm about the pivot axis between the first arm and the second arm even as the first arm moves pivotally relative to the base.
