Solution Overview
Problem
Existing screen units are bulky, difficult to handle, and lack flexibility in adjusting the projected area, with poor portability and installation complexity.
Innovation Solution
A screen unit comprising detachable panels with integrated first and second screen sheets and blocking films, attached to a foldable frame via magnets or hooks, allowing easy assembly and disassembly, and an intermediate member to ensure seamless image projection across panels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a rolled sheet screen is used to prevent wrinkles, then surface quality is improved, but weight increases and portability deteriorates
Solution Approach 1:
The screen is divided into multiple detachable panels that can be assembled and disassembled. Each panel is a separate unit that can be handled independently, reducing the overall weight burden and improving portability while maintaining surface quality through proper panel selection and assembly.
Solution Approach 2:
The screen transitions from a static rolled structure to a dynamic modular assembly. The panels can be easily assembled and disassembled, allowing the screen to adapt between different states (stored and deployed) while maintaining surface quality through controlled assembly procedures.
2Area of stationary object
If a large screen sheet is stretched over a holder, then projected area is maximized, but ease of handling and installation deteriorates
Solution Approach 1:
The large screen is segmented into multiple smaller panels that can be handled individually during installation and storage. This segmentation makes the screen easier to handle and install while maintaining the ability to achieve large projected areas when all panels are assembled together.
Solution Approach 2:
The screen assembly allows for flexible configuration in three-dimensional space. Panels can be arranged in various configurations and easily assembled or disassembled, providing ease of handling while maintaining the capability to achieve large projected areas through strategic panel arrangement.
3Device complexity
If a fixed screen configuration is used, then structural simplicity is maintained, but adaptability for different projected areas deteriorates
Solution Approach 1:
The screen is divided into modular panels that can be selectively assembled to create different projected areas and configurations. This segmentation provides adaptability for different applications while maintaining relatively simple individual panel structures that are easy to manufacture and assemble.
Solution Approach 2:
The modular panel design allows the same basic screen unit to serve multiple functions and configurations. The panels can be assembled in various arrangements to achieve different projected areas, making the screen adaptable to different applications while maintaining structural simplicity through the use of standardized components.

AI summary
A screen unit includes: a frame; a plurality of panels configured to display an image projected by a projector and configured to be detachably attachable to the frame; and an intermediate member configured to display the image projected by the projector and being provided across the plurality of panels in a state where the plurality of panels are detachably attached to the frame. Each of the plurality of panels includes a first screen sheet, a first blocking film configured to block light, and a base material. The intermediate member includes a second screen sheet and a second blocking film. The first screen sheet and the second screen sheet have the same optical characteristics as each other, and the first blocking film and the second blocking film have the same optical characteristics as each other.
