Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing screen units are bulky, difficult to handle, and lack flexibility in projected area adjustment, with poor portability and installation ease.
Innovation Solution
A screen unit comprising detachable panels with interchangeable intermediate members, each equipped with screen sheets and blocking films of matching optical characteristics, allowing easy assembly and disassembly, and enabling flexible area adjustment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a rolled sheet screen is used to prevent wrinkles, then the screen surface quality is improved, but the portability deteriorates due to thick and heavy construction
Solution Approach 1:
The screen is divided into multiple separate panels (first screen panel, second screen panel, etc.) that can be individually handled and assembled. Each panel contains its own screen sheet mounted on a support structure, allowing the overall screen to be segmented into manageable units that are lighter and more portable while maintaining wrinkle-free surfaces on each panel.
2Stability of the object's composition
If one large screen sheet is stretched over the holder, then the screen continuity is improved, but the ease of operation deteriorates due to difficulty in handling
Solution Approach 1:
The screen is divided into multiple separate panels (first screen panel, second screen panel, etc.) that can be individually handled and assembled. Each panel contains its own screen sheet mounted on a support structure, allowing the overall screen to be segmented into manageable units that are lighter and more portable while maintaining wrinkle-free surfaces on each panel.
Solution Approach 2:
Multiple screen panels are designed to be assembleable into a unified screen structure, with panels that can be nested or connected together. The support structures and frames are designed to interlock or join, allowing individual panels to be assembled into a complete screen system while maintaining the ability to disassemble for easy handling and storage.
3Ease of manufacture
If a fixed screen configuration is used, then the manufacturing simplicity is improved, but the adaptability deteriorates due to inability to change projected area
Solution Approach 1:
The screen system is designed with movable and adjustable components, including panels that can be repositioned, removed, or reconfigured. The support structures include movable parts that allow the screen area to be dynamically adjusted, enabling the same basic structure to provide different projected areas for various application needs.
Solution Approach 2:
The screen panels and support structures are designed with universal features that allow them to serve multiple functions and configurations. The same panel components can be used in different arrangements to create screens of various sizes and shapes, and the system can adapt to different mounting locations and projection requirements.

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.
