Collapsible Portable Display with Sliding-Arm Deployment Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing portable display devices lack a compact and efficient solution for quickly deploying a large screen in various settings, often requiring complex assembly and not incorporating built-in projectors for self-contained presentations.
Innovation Solution
A collapsible, portable display device with a Spontaneous Pop-Up Display (SPUD) mechanism that stores in a compact form and expands to provide a large screen using collapsible arms and a shroud, optionally including a built-in projector, allowing for easy setup and use in multiple configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If a portable display device uses a compact storage form, then portability and ease of carrying are improved, but the deployment speed and ease of setup are worsened
Solution Approach 1:
The display device is divided into multiple collapsible arms that can be independently folded and stored. Each arm contains support structures that segment the overall deployment mechanism, allowing the device to be broken down into compact segments for portability while maintaining the capability to reconstruct the full display structure when deployed.
Solution Approach 2:
The collapsible arms are pre-configured with support structures and connection mechanisms that enable automatic or semi-automatic deployment. The arms are designed with predetermined folding patterns and support element positions that guide the user through rapid setup without requiring complex assembly instructions or tools.
2Volume of moving object
If a portable display device uses a compact storage form, then portability is improved, but the screen size and display area are worsened
Solution Approach 1:
The display device employs dynamically adjustable collapsible arms that can transition between compact folded positions and extended display positions. The support structures within each arm are designed to maintain structural integrity during deployment while allowing the overall screen area to expand significantly from the compact storage form, achieving a high ratio between deployed and stored dimensions.
3Ease of manufacture
If a portable display device uses simple structure, then ease of manufacture and cost are improved, but image contrast and dust resistance are worsened
Solution Approach 1:
The device incorporates a shroud that acts as a flexible enclosure around the projection area and internal components. This shroud serves dual purposes: it is simple enough to manufacture as a single or few-piece flexible component, yet it effectively prevents dust from entering the projection path and contaminating optical elements, thereby maintaining image contrast without complex sealing mechanisms.

AI summary
The present invention provides an improved collapsible portable, display device. The improved collapsible, portable display device, has a housing having a sliding member aligned on the exterior of the housing and sliding along the exterior of said housing between two operating positions, a collapsible screen capable of displaying an image when in an expanded operating position, and multiple collapsible members connected to said screen and connected to said sliding member and said housing, and the collapsible members move said screen between the collapsed and expanded operating positions as said sliding member moves between a first collapsed operating position and a second popped-up position.
