Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current 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 dynamic environments where pivot, tilt, and elevating motions are required 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 structured base and wheel assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed base structure is used for the display device, then manufacturing simplicity is maintained, but adaptability and freedom of angle/position adjustment are limited
Solution Approach 1:
The base is divided into an upper base and a lower base that can rotate relative to each other around a rotation axis. This segmentation allows the display panel to achieve multiple angles and positions by rotating the upper base independently, providing adaptability without requiring a completely complex reconfigurable structure.
Solution Approach 2:
The base structure transitions from a fixed static design to a dynamic one where the upper base can rotate relative to the lower base. This dynamic capability enables the display device to adjust to different viewing angles and positions while maintaining a relatively simple overall structure through controlled rotational movement.
2Stability of the object's composition
If a simple base structure is used, then device complexity is reduced, but standing stability is insufficient
Solution Approach 1:
A weight is disposed within the lower base to serve as a counterweight that enhances standing stability. The weight's position and mass are designed to lower the center of gravity and provide stability against the rotational movement of the upper base, ensuring the display device remains stable during angle adjustments.
Solution Approach 2:
The stability solution extends into a different dimension by adding vertical weight distribution within the lower base rather than simply increasing the horizontal footprint. The weight is positioned to create a stable center of gravity that resists tipping during rotation, providing stability through three-dimensional mass distribution.
3Ease of operation
If the display panel is fixed in position, then structural simplicity is maintained, but ease of operation for different viewing angles is reduced
Solution Approach 1:
The support structure is segmented into an arm and a two-part base system. The arm connects the display panel to the upper base, which can rotate relative to the lower base. This segmentation allows independent adjustment of the display angle through rotation of the upper base while keeping the arm structure relatively simple.
Solution Approach 2:
The base transitions from a fixed structure to a dynamic one where the upper base can rotate relative to the lower base. This dynamic rotation capability enables easy adjustment of the display panel's viewing angle without requiring complex mechanical arms or multiple adjustment mechanisms.
4Reliability
If driving stability on moving bases is not considered, then device complexity is reduced, but reliability in mobile applications deteriorates
Solution Approach 1:
A weight is disposed within the lower base to enhance driving stability when the display device is placed on a moving base such as a wheelchair or cart. The weight's strategic positioning lowers the center of gravity and provides stability during movement, preventing tipping and ensuring reliable operation in mobile applications.
Solution Approach 2:
The stability solution addresses mobile application requirements by adding vertical weight distribution within the lower base rather than simply increasing the horizontal footprint. This three-dimensional mass distribution creates a stable center of gravity that resists tipping during acceleration, deceleration, and turning on moving bases.
