Projector Shade Structure With Tilt Adjustment for Compact Aesthetics
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional illumination devices with projectors often compromise on aesthetics due to the projector's visibility and require larger sizes when adjusting projection directions, limiting installation flexibility and convenience.
Innovation Solution
An illumination device with a projector that incorporates a projector holding section, a stand part, and a shade with a projection opening, featuring an angle adjustment mechanism to tilt the projector, allowing for variable projection directions without the need for internal mirrors, thus maintaining a compact size and concealing the projector's presence.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a mirror is disposed inside the shade to change the projection direction, then the projection direction can be adjusted, but the illumination device grows in size
Solution Approach 1:
The patent extracts the mirror component from the system and replaces it with a projector mounting structure that allows direct angle adjustment. The projector is mounted on a support post with an angle adjustment mechanism that enables tilt angle change without requiring internal mirrors, thereby reducing the device volume while maintaining projection direction adjustability.
Solution Approach 2:
The patent implements a dynamic mounting structure where the projector can be tilted at various angles relative to the shade. The angle adjustment mechanism allows the projector to be positioned at different orientations, enabling flexible projection direction control without the need for fixed mirrors, thus reducing the overall device size.
2Shape
If the projector is mounted inside the shade to conceal it, then the appearance is improved, but the projection direction adjustment becomes limited
Solution Approach 1:
The patent employs a dynamic mounting structure that allows the projector to be tilted at various angles while remaining mounted inside the shade. The angle adjustment mechanism enables the projector to be positioned at different orientations, maintaining aesthetic concealment while providing flexible projection direction control to adapt to different installation spaces and purposes.
3Ease of repair
If the projector is made visible to allow easy access, then maintenance becomes easier, but the aesthetic appearance deteriorates
Solution Approach 1:
The patent divides the illumination device into separable components: the shade and the projector mounting section. The projector is mounted on a support post that can be detached from the shade, allowing easy access for maintenance while maintaining aesthetic appearance during normal use. This segmentation enables independent access to the projector without compromising the overall aesthetic integration.

AI summary
An illumination device with projector includes a projector having a projection optical system, a projector holding section configured to hold the projector, a stand part to be coupled to the projector holding section, and a shade which is configured to cover a periphery of the projector holding section, and is provided with a projection opening through which projection light emitted from the projector is transmitted. The projector holding section is provided with an angle adjustment mechanism for changing a tilt angle of the projector centering on an end portion at an exit side of the projector.
