Multi-Projector Position Adjustment via Conjoined Rotary Tables
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing multi-stacking projection apparatus requires separate adjustment of tilt and left-right mechanisms for each projector, making the projection position adjustment of image light from multiple projectors complex and cumbersome.
Innovation Solution
A position adjustment apparatus with two rotary tables, one for each projector, that rotate in opposite directions in conjunction with each other, allowing simultaneous adjustment of the projection direction and size of images projected by multiple projectors, eliminating the need for individual adjustment of each projector's tilt and left-right mechanisms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If separate tilt and left-right adjustment mechanisms are used for each projector, then the projection direction of each projector can be adjusted, but the operation becomes complicated and time-consuming
Solution Approach 1:
The patent combines multiple adjustment functions (tilt and left-right adjustments for multiple projectors) into a single integrated rotary table mechanism. By mounting multiple projectors on one rotary table and rotating the entire table, all projectors are adjusted simultaneously with one operation, eliminating the need for separate adjustment mechanisms for each projector and significantly simplifying the operation.
Solution Approach 2:
The rotary table serves multiple functions: it acts as a mounting platform for multiple projectors, provides simultaneous tilt adjustment for all projectors, enables left-right positioning adjustments, and allows rotation to change projection angles. This multi-functional design replaces what would otherwise require multiple separate adjustment mechanisms.
2Productivity
If multiple adjustment mechanisms are provided for each projector, then the projection position can be adjusted, but the adjustment time increases
Solution Approach 1:
The patent merges the adjustment operations of multiple projectors into a single rotational action. When the rotary table rotates, all projectors mounted on it are adjusted simultaneously, reducing the adjustment time from multiple sequential operations to one concurrent operation, thereby significantly improving productivity and reducing time loss.
Solution Approach 2:
The projectors are pre-mounted on the rotary table in specific positions and orientations. This preliminary arrangement allows them to be adjusted simultaneously through table rotation, eliminating the need for individual adjustment operations during the actual projection setup and thus reducing adjustment time.
3Ease of operation
If individual adjustment mechanisms are used for each projector, then precise control is possible, but the device structure becomes complex
Solution Approach 1:
The patent merges multiple individual adjustment mechanisms into a single rotary table structure. Instead of having separate tilt and left-right mechanisms for each projector, all adjustments are achieved through the rotation of one integrated table, significantly simplifying the overall device structure while maintaining adjustment capability.
Solution Approach 2:
The rotary table is divided into multiple segments or mounting positions, each capable of holding a projector. This segmentation allows multiple projectors to be independently positioned on the table while still being adjusted collectively through table rotation, maintaining operational simplicity without sacrificing positioning flexibility.

AI summary
A position adjustment apparatus includes a housing including a first space in which a first projector is disposed and a second space in which a second projector is disposed, a first rotary table on which the first projector is placed and which is rotatably supported by the housing about a first rotation axis, and a second rotary table on which the second projector is placed and which is rotatably supported by the housing about a second rotation axis. The housing includes a first opening through which first image light from the first projector passes and a second opening through which second image light from the second projector passes. A rotation direction of the first rotary table and a rotation direction of the second rotary table are opposite to each other. Rotation of the first rotary table and rotation of the second rotary table are in conjunction with each other.
