Projector Mount Adjustment Mechanism for Independent Multi-Axis Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing projector and electronic whiteboard adjusting mechanisms lack the ability to independently adjust angles in all directions efficiently, leading to difficulty and time consumption in precise angle adjustments.
Innovation Solution
An adjusting mechanism comprising a fixing base, a rotary plate, and multiple screws that are ball-jointed to allow independent rotation of the projection unit along various axes without causing angle deviations in other directions, utilizing a combination of first, second, and third screws to facilitate adjustments along X, Y, and Z axes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a traditional mounting mechanism with angle-adjusting function is used, then the projector can be mounted to ceiling or wall, but the adjustment of angles in all directions cannot be performed independently and efficiently
Solution Approach 1:
The adjusting mechanism is segmented into multiple independent adjustment components: a rotary plate for azimuth adjustment and a pitch adjustment mechanism with a pitch rod and pitch wheel. This segmentation allows independent adjustment of different angles (azimuth and pitch) without affecting each other, enabling efficient multi-directional angle adjustment while reducing adjustment time
2Adaptability or versatility
If multiple adjustment functions are integrated into one mechanism, then angle adjustment capability is improved, but the mechanism complexity increases
Solution Approach 1:
The mechanism is divided into distinct functional modules: a rotary plate component for azimuth adjustment and a separate pitch adjustment component with pitch rod and pitch wheel. Each module handles a specific adjustment function independently, maintaining structural clarity and ease of manufacture while achieving versatile multi-directional adjustment capability
Solution Approach 2:
The rotary plate serves as an intermediary component that connects the fixing base to the projection unit while providing a bearing surface. This intermediary structure enables both azimuth rotation and pitch adjustment functions to be implemented through simple, standardized mechanical interfaces rather than a complex integrated mechanism

Function Achieved in This Case
Enables precise and independent angle adjustments of the projection unit in all directions, reducing adjustment difficulty and saving time by allowing controlled rotation along specific axes without affecting other angles, thus improving the ease and speed of alignment.
Implementation Method 1
The rotary plate is pivotally connected to the fixing base, and is adapted to be ball jointed to the projection unit
Implementation Method 2
The first screw drives the projection unit to rotate relatively to the rotary plate along a first axis when the first screw is rotated
