Adjustable Projection Ring with Telescopic Projector
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing projection rings that incorporate a projector into a ring face difficulties in adjusting the projection location, making them inconvenient to operate effectively.
Innovation Solution
A projection ring with a telescopic portion allows adjustable projection location and angle by extending or retracting the projector, which is rotatably connected to an annular body, enabling comfortable wear and enhanced display options without needing to reposition the ring on the finger.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the projector is fixed in the ring, then the structure is simple, but the projection location cannot be adjusted
Solution Approach 1:
The patent applies the dynamics principle by transforming the fixed projector structure into a movable one through a telescopic mechanism. The projector can be extended or retracted along the central axis of the ring, allowing dynamic adjustment of projection distance and angle while maintaining a relatively simple overall structure. This resolves the contradiction by enabling adaptability without significantly increasing structural complexity.
2Area of stationary object
If the projector is extended to increase projection size, then the display area increases, but the ring size increases
Solution Approach 1:
The patent applies segmentation by dividing the ring into a fixed annular body and a movable telescopic portion. The projector is mounted on the telescopic portion, which can be extended only when needed for projection, while the main ring body remains compact for comfortable wearing. This allows the projection area to be increased without permanently increasing the ring size.
3Ease of operation
If the projector is made adjustable, then the projection angle can be optimized, but the operation complexity increases
Solution Approach 1:
The patent uses a telescopic mechanism that provides simple linear movement for adjusting the projector's position and angle. The telescopic portion can be extended or retracted along the central axis of the ring, allowing easy adjustment of projection parameters without complex mechanisms. This maintains ease of operation while providing the necessary adjustability.

AI summary
Disclosed is a projection ring, including an annular body (1); a telescopic portion (2) disposed on the annular body (1); and a projector (3) disposed on the telescopic portion (2). The location of the projector on the projection ring is easily adjustable, thus it's convenient to adjust the size of the picture as projected or the projection angle.
