Collapsible Screen Display With Adjustable Arms
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing portable display devices with collapsible screens face challenges in achieving a centered and fully displayed image due to mechanical tolerances, leading to potential image shifting, rotation, or cutoff.
Innovation Solution
The Splay device incorporates a portable display device with a built-in projector, a collapsible and removable screen, and improved screen and shroud materials. It features a deployment mechanism with sliding members and adjustable arms that allow for image centering and correction, ensuring a fully displayed image.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If a collapsible screen is attached to a portable display device, then the device can be stored in a compact form, but the screen may become misaligned, shifted, or rotated during deployment
Solution Approach 1:
The patent implements adjustable arm members with telescopic sections that can dynamically change length during deployment. The arms extend from a retracted state during storage to an extended state during display, automatically maintaining proper screen alignment and tension regardless of manufacturing tolerances. This dynamic adjustment resolves the contradiction between compact storage and precise image alignment.
2Device complexity
If fixed-length arms are used to support the screen, then the structure is simpler, but the image cannot be properly centered or corrected for alignment issues
Solution Approach 1:
The arm members incorporate telescopic sections with extendable and retractable elements, allowing the arm length to be dynamically adjusted. This enables the screen to be properly centered and aligned during deployment while maintaining a relatively simple overall structure. The adjustment mechanism is integrated into the arm design itself, avoiding the need for separate complex alignment systems.
3Stability of the object's composition
If the screen is made rigid and fixed, then the image display is stable, but the device cannot be stored in a compact portable form
Solution Approach 1:
The screen is attached to adjustable arm members that can dynamically change from a retracted configuration during storage to an extended configuration during display. This dynamic structure provides stability and proper tension when deployed for image display, while allowing the entire assembly to be collapsed into a compact form for portable storage, resolving the contradiction between stability and portability.
