Counterweighted Display Stand With Wheel Base for Multi-Axis Motion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices lack the ability to freely adjust the angle or position of the display panel, limiting their flexibility and stability, especially when used in various motion configurations such as pivot, tilt, and swivel motions independently.
Innovation Solution
A display device design featuring a head with a display panel, an arm, a pole, and a base that includes a weight and wheel system, allowing for independent pivot, tilt, and elevating motions, while improving standing and driving stability through a structured stand configuration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a display device uses a fixed stand structure, then manufacturing is simple, but the display panel cannot be freely adjusted in angle or position
Solution Approach 1:
The stand structure is divided into multiple independent segments: a base, a pole, an arm, and a head assembly. Each segment can move independently relative to others, enabling multiple degrees of freedom (pivot, tilt, swivel, elevating motions) while keeping each individual component relatively simple in design.
Solution Approach 2:
The stand transitions from a static fixed structure to a dynamic adjustable structure. The head assembly is designed with movable connections that allow it to perform pivot motion (rotation around vertical axis), tilt motion (rotation around horizontal axis), swivel motion, and elevating motion independently, providing adaptability without requiring complete structural redesign.
2Adaptability or versatility
If the display device allows multiple independent motions (pivot, tilt, swivel, elevating), then versatility improves, but structural complexity increases
Solution Approach 1:
Each motion degree of freedom is implemented as a separate functional module within the head assembly. The pivot mechanism, tilt mechanism, swivel mechanism, and elevating mechanism are segmented into distinct components that can operate independently, allowing complex overall functionality while maintaining simplicity at each module level.
Solution Approach 2:
The head assembly employs a nested structure where multiple motion mechanisms are arranged concentrically or hierarchically. The arm is rotatably coupled to the pole, and the head is pivotally coupled to the arm, creating a nested arrangement where each component is contained within or connected to the previous one, reducing overall structural footprint while maintaining multiple degrees of freedom.
3Reliability
If the base includes a wheel system coupled to a weight, then mobility and stability improve, but device complexity increases
Solution Approach 1:
A weight is disposed within the base structure to provide counterbalancing force. This weight serves dual purposes: it acts as a counterweight to stabilize the display device during operation and provides ballast to improve stability during mobility operations. The wheel system is coupled to this weight, allowing the heavy base to be moved when needed while remaining stable during use.
Solution Approach 2:
The base integrates multiple functions into a single structure: it serves as the support foundation, contains the weight for stability, and incorporates the wheel system for mobility. By merging these functions into one integrated base assembly rather than separate components, the overall device complexity is reduced while achieving both standing stability and driving mobility.
