Projector Adjustment Mechanism for Post-Installation Orientation Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing projector installations in ceilings or floors face challenges in adjusting the position or orientation of the projector after installation, making it difficult to achieve the desired projection state.
Innovation Solution
A projector design that includes an adjustment mechanism allowing for rotation and inclination adjustments of the projection section relative to the installation surface, coupled with an operation element and a control system, enabling post-installation adjustments of the projection state without compromising aesthetic appearance or functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the projector is fixed with volts in a ceiling space, then the device position is fixed during installation, but the position or posture cannot be adjusted after installation
Solution Approach 1:
The patent applies the dynamics principle by providing an adjustment mechanism that enables the projection section to be rotated and inclined after installation. The mechanism includes a rotation mechanism for rotating the projection section around an axis perpendicular to the installation surface, and an inclination adjustment mechanism for adjusting the inclination angle of the projection section, transforming the static fixed installation into a dynamically adjustable system.
2Ease of operation
If adjustment mechanisms are provided for post-installation adjustment, then the projection state can be adjusted, but the aesthetic appearance may be compromised
Solution Approach 1:
The patent applies the extraction principle by providing a cover that hides the adjustment mechanisms from view. The cover is configured to cover the rotation mechanism and inclination adjustment mechanism when the projector is installed in the ceiling, extracting the aesthetic function from the mechanical adjustment components while preserving their functionality.
3Adaptability or versatility
If the projection section is made adjustable with multiple mechanisms, then the projection state can be precisely adjusted, but the device complexity increases
Solution Approach 1:
The patent applies the merging principle by integrating the rotation mechanism and inclination adjustment mechanism into a unified adjustment system. Both mechanisms share a common drive shaft and control structure, allowing the projection section to be adjusted in both rotation and inclination through coordinated operation of the adjustment member, thereby reducing overall system complexity.

AI summary
A projector is configured to project an image to one side with respect to an installation surface. The projector includes: a housing that is configured to be fixed to the installation surface, a projection section that is built in the housing and configured to project image light from one end of the housing, an adjustment mechanism that is configured to adjust a posture of the projection section with respect to the installation surface, a drive section that is configured to drive the adjustment mechanism, and an operation detecting section configured to detect an input operation corresponding to the adjustment mechanism.
