Weighted Wheeled Display Stand for Stable Multi-Axis Adjustment
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 modes 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 enhancing standing and driving stability through a weighted and wheeled base structure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed base structure is used, then manufacturing simplicity is maintained, but adaptability and motion adjustment capability are limited
Solution Approach 1:
The base is divided into an upper body and a lower body as separate components. The lower body contains the wheel assembly while the upper body receives the pole, allowing independent design optimization of each segment for both simplicity and adaptability
Solution Approach 2:
The base incorporates a wheel assembly that enables the base to move dynamically across surfaces. This dynamic capability allows the display device to adapt to different positions and orientations without requiring a completely complex reconfigurable structure
2Ease of operation
If a lightweight base is used, then ease of movement is improved, but standing stability deteriorates
Solution Approach 1:
The base structure separates the functions of movement (lower body with wheel) and stability (upper body receiving pole). This segmentation allows the lower body to be optimized for ease of movement while the upper body provides structural stability when the device is in use
Solution Approach 2:
The design changes the operational parameters of the base by introducing a movable wheel mechanism. The base transitions between a mobile state (when wheel is engaged) and a stable support state (when pole is mounted), optimizing both ease of movement and standing stability at different operational phases
3Adaptability or versatility
If multiple motion capabilities are added, then adaptability improves, but device complexity increases
Solution Approach 1:
Multiple motion capabilities (pivot motion at the joint, tilt motion through arm adjustment, and swivel motion through base rotation) are merged into a unified structure. The arm assembly integrates pivot and tilt functions, while the base integrates swivel capability, reducing overall system complexity compared to separate mechanisms for each motion type
Solution Approach 2:
The arm assembly serves multiple functions: it provides pivot motion connection between head and base, enables tilt adjustment capability, and acts as a structural support element. This multi-functionality reduces the need for separate components for each motion type, thereby reducing overall device complexity
