Display Support Arm Mechanism for Stable Mobile Cart Positioning
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 the support structure tipping over.
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 limiting the range of movement to prevent accidental displacement and tipping.
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 moved or repositioned
Solution Approach 1:
The apparatus transitions from a static fixed mounting to a dynamic mobile cart configuration with adjustable arms. The cart can be moved to different locations, and the arms can be adjusted to different positions and angles, providing both mobility and secure display holding through mechanical constraints and friction.
2Adaptability or versatility
If the display support apparatus allows free movement on a mobile cart, then the apparatus is versatile and mobile, but the display may accidentally move or cause the cart to tip over
Solution Approach 1:
The apparatus applies preliminary counteracting forces through friction between the cart wheels and ground, and through mechanical constraints in the arm joints. These pre-applied stabilizing forces prevent accidental movement and tipping before they can occur during cart maneuvering.
Solution Approach 2:
The apparatus changes the stability parameters by adjusting the arm positions and angles, which alters the center of mass location and the distribution of forces on the cart. This allows the system to maintain stability across different display positions while preserving mobility.
3Stability of the object's composition
If the base is fixedly attached to the support structure, then the apparatus is stable, but the base cannot be repositioned or removed
Solution Approach 1:
The base attachment system transitions from a permanently fixed configuration to a dynamically adjustable one. The base can be securely attached to the cart for stable operation, but can also be quickly detached and repositioned when needed, providing both stability during use and ease of reconfiguration.
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 displays in place on mobile carts, reducing the risk of damage or injury and preventing the cart from tipping by maintaining the display's center of mass within a stable footprint, ensuring safe and controlled 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.
