Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mobile devices with large screens face challenges in reducing size for portability while maintaining usability, as techniques to minimize size are limited by the constraints of flexible LCDs and bezel reduction.
Innovation Solution
A reconfigurable mobile device design featuring a multistage supporter with movable bodies and a projector system that allows the screen to extend for maximum size and fold for minimum size, using a projector system and screen lamination for image projection and reflection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of moving object
If the display size is increased to improve usability for stream content and social network services, then the screen area is improved, but the device size and portability deteriorate
Solution Approach 1:
The patent applies a telescopic structure that allows the display to dynamically change size between extended and retracted states. The display can be extended to a large size during use for optimal viewing experience, then retracted to a compact form for portability, resolving the contradiction between having a large screen and maintaining small device dimensions.
Solution Approach 2:
The display is divided into multiple segments that can be independently controlled. The telescopic structure segments the display into extendable sections, allowing selective extension of the display area while keeping the overall device structure compact when not in use.
2Length of moving object
If flexible LCD is folded to reduce device size for portability, then the device thickness is reduced, but the folded portion requires large radius which prevents sufficient size reduction
Solution Approach 1:
Instead of using a static folded structure, the patent employs a dynamic telescopic mechanism where the display can be extended or retracted along a linear path. This dynamic structure allows the display to achieve compact retraction without requiring large radius folds, enabling thinner device profiles while maintaining structural simplicity.
3Area of moving object
If the display is extended to maximum size for use, then the screen area is maximized, but the device cannot be compacted for transportation
Solution Approach 1:
The telescopic structure enables the display to adapt between two extreme states: fully extended for maximum screen area during use, and fully retracted for compact transportation. This dynamic size adjustment provides versatility, allowing the device to serve both large-screen viewing needs and portable carrying requirements.
Solution Approach 2:
The telescopic mechanism nests the display segments within each other when retracted, similar to nested dolls. The display can be compacted into a small form factor for transportation, then extended to full size for use, providing size adaptability between compact and large configurations.
