Auto-Expandable Display Stand Base for Tilt Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Commercially available display stands with ergonomic features like adjustable height and tilt often become unstable due to increased screen sizes and weights, limiting the benefits of ergonomic adjustments for viewers.
Innovation Solution
An auto-expandable base structure with a swivel member, linking member, and extensible member that adjusts to maintain stability by changing the center of gravity and increasing the virtual base boundary, allowing for safe ergonomic adjustments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If adjustable height and tilt features are added to the stand, then ergonomic viewing angles are improved, but stability deteriorates due to increased screen sizes and weights
Solution Approach 1:
The base is designed to dynamically expand from a compact state during shipping to an expanded stable state during use. The extensible member automatically extends when the display panel is tilted, increasing the base area to maintain stability during ergonomic adjustments.
Solution Approach 2:
The stability solution extends into a third dimension by allowing the base to expand outward horizontally when needed. The extensible member projects beyond the original base boundary, creating a larger support footprint that prevents tipping during tilt adjustments.
2Stability of the object's composition
If the base is made larger to improve stability, then stand stability is improved, but shipping cost increases due to larger package size
Solution Approach 1:
The base transitions from a small compact configuration during shipping to a large expanded configuration during use. The extensible member is stored within or adjacent to the main base during shipping, then automatically extends when the display panel is tilted, providing stability only when needed.
Solution Approach 2:
The extensible member is designed to nest within or alongside the main base structure during shipping. This allows the base to occupy minimal space during transport while still providing the capability to expand to a larger stable configuration during actual use.
3Stability of the object's composition
If the extensible member is always extended to maintain stability, then stand stability is improved, but device complexity increases
Solution Approach 1:
The extensible member automatically extends and retracts based on the tilt angle of the display panel without requiring user intervention. The mechanism self-activates when the panel is tilted beyond a certain angle, extending the base to maintain stability, and self-retracts when the panel returns to its normal position.
Solution Approach 2:
The system uses the tilt angle of the display panel as feedback to control the extension state of the extensible member. When the panel is tilted, the mechanism detects this change and automatically extends the base; when the panel returns to normal position, the base automatically retracts, creating a closed-loop stability control system.
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 auto-expandable base provides improved stability and safety during ergonomic adjustments, maintaining the center of gravity within a stable boundary even with increased screen sizes and weights, while being compactable for shipping cost reduction.
Implementation Method 1
The linking member is frictionally coupled to the swivel member. The linking member is rotatably movable in response to a rotational motion of the swivel member. The rotational motion of the swivel member is transferred by the linking member to cause a linear motion of the extensible member.

AI summary
For stabilizing a stand to mount a display, the stand includes a base support member having a center portion with a circular recess formed about an axis perpendicular to the base support member. A swivel member removably coupled to the center portion is rotatably movable about the axis and within the circular recess. A linking member removably coupled to the center portion, is frictionally coupled to the swivel member. The linking member is rotatably movable in response to a rotational motion of the swivel member. An extensible member extensible member removably coupled to the center portion is frictionally coupled to the linking member. The rotational motion of the swivel member is transferred by the linking member to cause a linear motion of the extensible member. The linear motion of the extensible member increases a virtual base boundary formed by the extensible member and the base support member thereby improving the stability of the stand.
