Removable Auxiliary Screen for Mobile Device Display
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile devices, such as cellular phones and PDAs, face challenges in displaying images due to small screen sizes, especially in bright environments or when multiple users need to view the content.
Innovation Solution
A removable display system for mobile devices that includes a primary screen and an auxiliary screen, which can be attached to the device, providing an enlarged viewable area that is collapsible, foldable, or rollable, allowing for easy transportation and use in various settings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If the display screen of a mobile device is made small for portability, then the device becomes more portable and easier to hold, but the display becomes difficult to view, particularly in certain lighting or in the presence of glare
Solution Approach 1:
The patent introduces a projection dimension by adding a projector that projects images onto an auxiliary screen, transforming the 2D display problem into a 3D spatial solution. This allows the image to be viewed on a larger surface area while maintaining the compact mobile device form factor.
Solution Approach 2:
The auxiliary screen acts as an intermediary between the mobile device's small display and the user's viewing experience. It receives the projected image and provides a larger, more visible display surface that can be viewed in various lighting conditions without the constraints of a small built-in screen.
2Area of stationary object
If a projector is added to a mobile device to project images on a wall, then the display area is enlarged, but the images projected on the wall may be dim and difficult to view, and it may not be feasible to project images on a wall at times
Solution Approach 1:
The auxiliary screen is designed to be flexible and adaptable, capable of being positioned in different locations and orientations. It can be used as a handheld display, placed on surfaces, or positioned to receive projections, providing dynamic viewing options that work in various environments where wall projection may not be feasible.
Solution Approach 2:
The display system is segmented into separate components: the mobile device with projector, and the separate auxiliary screen. This segmentation allows the projection function and the display surface to be independently optimized and positioned, enabling use in situations where projecting onto a wall is not possible.
3Area of stationary object
If an auxiliary screen is made large for group viewing, then group viewing is enabled, but the device becomes less portable and more expensive
Solution Approach 1:
The auxiliary screen utilizes flexible and thin materials that allow it to be easily folded, rolled, or collapsed into a compact form. This enables the screen to provide a large viewing area when needed while maintaining portability by being storable in a compact state that fits with or near the mobile device.
Solution Approach 2:
The auxiliary screen's structure is designed to be dynamically changeable between expanded and collapsed states. It can be deployed to a large size for group viewing and then collapsed back to a compact form for portability, providing adaptability between the two opposing requirements.
