Rotating Imaging Module for Tool-Free Projection Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current projection devices require complex tool-based adjustments for changing the projection direction, leading to increased volume and cost due to the need for indirect adjusting elements and additional components like electric motors or control circuits.
Innovation Solution
A projection device with a rotating module integrally formed on a mounting surface, allowing manual rotation to adjust the projection direction without tools, thereby simplifying adjustments and reducing the need for additional components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If indirect adjusting elements are used to adjust the projection direction, then the projection direction can be adjusted, but the device complexity and volume increase
Solution Approach 1:
The patent removes indirect adjusting elements such as electric motors and control circuits from the projection device. The projection direction is adjusted directly by manually rotating the lens barrel itself, which extracts the complex adjustment mechanism while retaining the adjustment function.
Solution Approach 2:
Instead of using indirect adjusting elements to change the projection direction, the patent enables direct manual rotation of the lens barrel. This inverts the conventional approach by making the lens barrel itself rotatable without requiring additional adjustment mechanisms.
2Ease of operation
If indirect adjusting elements are contained in the lens barrel, then the projection direction can be adjusted, but the projector volume increases
Solution Approach 1:
The patent extracts indirect adjusting elements from the lens barrel, allowing the lens barrel to be rotated directly for projection direction adjustment. This removal of unnecessary components reduces the overall projector volume while maintaining the adjustment capability.
3Extent of automation
If electric motor or control circuit is added for automatic adjustment, then the projection direction can be automatically adjusted, but the projector cost increases
Solution Approach 1:
The patent removes electric motors and control circuits from the projection device, eliminating the need for automatic adjustment mechanisms. The projection direction is adjusted manually by rotating the lens barrel, which significantly reduces the cost of manufacturing while maintaining the adjustment function.
Solution Approach 2:
The lens barrel is designed to be directly rotatable by hand, allowing the user to adjust the projection direction without requiring external power sources or control systems. This self-service approach eliminates the need for expensive automatic adjustment components.

AI summary
The invention provides a projection device which includes a rotating module and an imaging module. The rotating module is assembled on a mounting surface and includes a rotating part and an assembling part which are integrally formed. The rotating part is parallel to the mounting surface, and the assembling part is perpendicular to the mounting surface. The imaging module is assembled on the assembling part of the rotating module. When the rotating module rotates by taking an axis perpendicular to the mounting surface as an axial center, the rotating module drives the imaging module to rotate so as to change a projection direction of the imaging module. The projection device of the invention adjusts the projection direction without using a tool.
