Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional ball-and-socket joint type supporting devices used in meeting or audiovisual rooms lack the capability for micro-adjustment of rotational and tilt angles, limiting precise alignment of projectors with projection screens.
Innovation Solution
A micro-adjustable supporting device comprising a mounting seat, a movable unit with a rotating assembly, and an adjusting unit that includes tilt-adjusting elements and an angle-adjusting element, allowing for precise adjustments of the projector's rotational and tilt angles by connecting through a ball-and-socket joint mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a conventional ball-and-socket joint type supporting device is used, then the projector can be mounted to the ceiling with basic rotational and tilt angle adjustment, but micro-adjustment capability is lost
Solution Approach 1:
The supporting device is divided into distinct functional modules: a mounting seat for ceiling attachment, a movable unit containing the rotating assembly and bottom seat assembly, and an adjusting unit with separate tilt-adjusting elements and angle-adjusting element. This segmentation allows each component to perform its specific function while enabling micro-adjustment capabilities without requiring complete structural redesign.
Solution Approach 2:
The device incorporates movable components including the rotating assembly that can rotate about a central axis, the bottom seat assembly that can tilt relative to the axis, and adjusting elements that can move relative to each other. These dynamic elements enable continuous micro-adjustment of rotational and tilt angles, transforming the static ball-and-socket joint into a dynamically adjustable system.
2Ease of operation
If the supporting device structure is simplified to a ball-and-socket joint, then device complexity is reduced, but the capability for precise rotational and tilt angle adjustment is compromised
Solution Approach 1:
The adjusting unit acts as an intermediary mechanism between the operator and the movable unit. The tilt-adjusting elements and angle-adjusting element serve as mediators that translate operator input into precise micro-adjustments of the bottom seat assembly's tilt angle and rotational angle, respectively, enabling accurate positioning without complex direct manipulation.
Solution Approach 2:
The device enables independent adjustment of multiple angular parameters: the tilt angle of the bottom seat assembly relative to the central axis (controlled by tilt-adjusting elements) and the rotational angle of the rotating assembly about the axis (controlled by the angle-adjusting element). This multi-parameter adjustment capability allows precise control of projector orientation while maintaining operational simplicity.

AI summary
A micro-adjustable supporting device includes a mounting seat, a movable unit, and an adjusting unit. The movable unit includes a rotating assembly disposed rotatably in the mounting seat and rotatable about an axis, and a bottom seat assembly disposed under the mounting seat and rotatable about the axis. The adjusting unit includes a pair of spaced-apart first and second tilt-adjusting elements, and an angle-adjusting element. Each of the first and second tilt-adjusting elements extends through the rotating assembly to connect with the bottom seat assembly, and is movable relative to the rotating assembly in a direction parallel to the axis to adjust a tilt angle of the bottom seat assembly relative to the axis. The angle-adjusting element is operable to move relative to the mounting seat to thereby rotate the rotating assembly and the bottom seat assembly about the axis.
