Projecting Device Rotating Mechanism for Image Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional LED projectors face challenges in projecting images effectively due to limitations in adjusting the projection position and angle, often resulting in blocked images and an inconvenient user experience, especially when the projection direction is horizontal or perpendicular to the wall.
Innovation Solution
A projecting device with a rotating and adjusting mechanism that allows the light emitting portion to adjust its angle by rotating through a gear structure, enabling the projection image to be positioned optimally on a target object such as a wall or ceiling, and includes a detector and controller to automatically adjust the image proportion based on detected position information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the projection direction is fixed horizontally or perpendicularly to the wall, then the projector structure is simple, but the projection position is limited and images are often blocked by the display
Solution Approach 1:
The patent applies the dynamics principle by implementing a rotating portion that enables the light emitting portion to change its projection angle dynamically. The rotating portion allows the projector to adjust between horizontal projection (toward the wall) and perpendicular projection (toward the ceiling), transforming a static structure into a dynamic one that can adapt to different projection scenarios and avoid being blocked by the display.
2Adaptability or versatility
If the projection angle is fixed, then the device structure is simple, but it is difficult to adjust the image to fit the projecting object
Solution Approach 1:
The adjusting portion works in conjunction with the rotating portion to dynamically adjust the projection angle. This allows the image to be fitted to different projecting objects (wall or ceiling) by changing the angle of the light emitting portion, thereby improving adaptability without requiring multiple fixed-angle projectors.
3Ease of operation
If the projection image position cannot be adjusted, then the projector is simple, but the image is blocked by the display monitor
Solution Approach 1:
By enabling dynamic angle adjustment through the rotating portion, the system can switch between projecting toward the wall and projecting toward the ceiling. This dynamic capability allows users to position the projection image in locations not blocked by the display monitor, improving ease of operation and eliminating the blocking issue.
4Ease of operation
If automatic image adjustment is not implemented, then the device is simpler, but manual adjustment is inconvenient for users
Solution Approach 1:
The patent implements a detector that detects the position information of the projection image and provides feedback to a controller. The controller then automatically adjusts the image proportion based on this feedback, eliminating the need for manual adjustment and significantly improving ease of operation. The feedback mechanism ensures the image is always properly fitted to the projecting surface regardless of the projection angle.

Function Achieved in This Case
Enables flexible and optimal positioning of the projection image, ensuring that the image is not blocked by the display monitor, providing a better game atmosphere by adjusting the angle and proportion to meet user requirements, enhancing both visual and audio effects.
Implementation Method 1
The light emitting portion is disposed in the main body and transmits a light through the first opening. The rotating portion is disposed in the main body and connected with the light emitting portion. The light emitting portion drives the rotating portion to rotate to adjust the angle of the light.
Implementation Method 2
The detector detects a position information of the projecting image with respect to the main body.
Implementation Method 3
The controller adjusts an image information of the graphic element according to the position information. In an embodiment, the image information is proportion of the graphic element.
