Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing projection technologies face challenges in efficiently adjusting the size of the projection area as the screen expands or contracts, leading to difficulties in maintaining optimal image quality and space utilization.
Innovation Solution
A projection apparatus comprising a screen, a reel, and a control assembly that allows the screen to be unfolded or wound, with the control assembly managing the projection display structure to adjust the image projection area accordingly, ensuring optimal image quality and space management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of moving object
If the screen is unfolded to increase display area, then the projection area can be enlarged, but the space utilization and image quality control become more difficult
Solution Approach 1:
The patent implements dynamic adjustment of the projection area that automatically adapts to the screen's unfolded state. The control assembly dynamically modifies projection parameters based on real-time screen position and area, enabling the system to optimize both projection quality and space utilization across different deployment states.
2Area of moving object
If the screen is unfolded to increase display area, then more content can be displayed, but maintaining optimal image quality becomes challenging
Solution Approach 1:
The control assembly incorporates feedback mechanisms that continuously monitor the screen's unfolded area and automatically adjust projection parameters to maintain optimal image quality. This closed-loop control ensures that image quality standards are preserved regardless of the projection area size.
Solution Approach 2:
The system dynamically changes projection parameters such as focal length, aperture, and projection distance based on the screen's unfolded area. By adjusting these parameters in real-time, the system maintains optimal image quality across different display areas.
3Volume of moving object
If the screen is wound to reduce space occupation, then space utilization improves, but the projection area decreases
Solution Approach 1:
The system provides dynamic control over the screening process, allowing the screen to be unfolded to full extent when projection is needed and wound back when not in use. The control assembly manages the transition between these states, optimizing the balance between space occupation and projection area availability.
