Projector Ceiling Hanger With Multi-Axis Fine Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ceiling hangers for projectors lack fine adjustment capabilities in multiple axes, expose components leading to poor appearance and dust accumulation, and struggle with cable management, making them unsuitable for home or office use.
Innovation Solution
A ceiling hanger system comprising four interlocking plates that allow for precise adjustments in horizontal, left-right, and up-down directions, with a cover member to conceal components and improve aesthetics, and a cable management system that minimizes external exposure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If a ceiling hanger is designed to attach the projector as close to the ceiling surface as possible, then the external appearance is improved, but fine adjustment of the projector position becomes difficult
Solution Approach 1:
The ceiling hanger is divided into multiple independent adjustment mechanisms: a first adjustment mechanism for horizontal direction, a second adjustment mechanism for left-right direction, and a third adjustment mechanism for up-down direction. Each mechanism can be operated independently to achieve fine position adjustments while maintaining a compact overall structure that attaches close to the ceiling surface.
2Ease of operation
If components are exposed to the outside for accessibility, then ease of operation is improved, but external appearance deteriorates and dust accumulation increases
Solution Approach 1:
The adjustment mechanisms and operational components are nested within the ceiling hanger structure, with the first, second, and third adjustment mechanisms integrated into the body of the hanger. This nested arrangement allows components to be accessible for operation while being concealed from external view, maintaining aesthetic appearance and preventing dust accumulation on operational parts.
3Measurement precision
If multiple adjustment axes are added for fine position control, then positioning precision is improved, but device complexity increases
Solution Approach 1:
The ceiling hanger employs three dynamic adjustment mechanisms that allow the projector to be positioned precisely in horizontal, left-right, and up-down directions. Each mechanism provides rotational or translational movement along a specific axis, enabling fine positioning control while maintaining a relatively simple overall structure through modular design.

AI summary
A ceiling hanger includes: a first plate fixed to a ceiling surface; a second plate forming a first rotation axis in the up-down direction after fitted to the first plate, and allowing control in the horizontal direction; a third plate forming a second rotation axis in the front-rear direction after fitted to the second plate, and allowing control in the left-right direction; and a fourth plate fixing a projector, forming a third rotation axis in the left-right direction after fitted to the third plate, and allowing control in the up-down direction.
