Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current light-emitting devices with large display regions face challenges in achieving both high portability and browsability, as they tend to be bulky and difficult to fold without damaging the display panel.
Innovation Solution
A light-emitting device design featuring a flexible panel supported by spaced housings that are magnetically fixed, allowing the panel to be bent and folded without mechanical jigs, using ferromagnets and soft magnetic substances to ensure secure attachment and prevent unintentional damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a large-sized display region is provided to improve browsability, then the display area increases, but the device becomes bulky and portability deteriorates
Solution Approach 1:
The light-emitting panel is divided into multiple segments that can be folded together. The panel includes first and second light-emitting panels that can be folded along a fold line, allowing the large display area to be compacted into a smaller portable form when not in use
Solution Approach 2:
The device transitions from a static large display to a dynamic folded structure. The light-emitting panel can be folded along a fold line to change between an unfolded state (large display area) and a folded state (compact portable size), adapting to different usage scenarios
2Length of moving object
If a flexible light-emitting panel is used to improve portability, then the device can be folded, but the panel may be damaged during folding and unfolding
Solution Approach 1:
Magnetic fixing members are pre-installed on the housing to automatically guide and secure the folded panel in its proper position. This preliminary magnetic positioning prevents misfolding or excessive bending that could damage the panel
Solution Approach 2:
Traditional mechanical latches or clips are replaced with magnetic fixing members. The magnetic force automatically holds the folded panel in place without requiring mechanical fastening components that could pinch or damage the flexible panel during folding operations
3Stability of the object's composition
If housings are provided to support the flexible panel, then structural stability improves, but the device complexity increases
Solution Approach 1:
The magnetic fixing members on the housing automatically perform the function of securing the folded panel without requiring additional mechanical components or complex assembly mechanisms. The magnetic force self-regulates to hold the panel firmly yet allow easy opening
Solution Approach 2:
The housing is designed with a simple structure that accommodates the flexible panel, using minimal rigid components necessary for support. The magnetic fixing members are integrated into the housing in a way that adds functional stability without significant structural complexity
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The design enhances portability and browsability by allowing seamless large display regions, reducing the risk of damage during folding and unfolding, and optimizing power consumption by hiding non-light-emitting regions when folded.
Implementation Method 1
two of the plurality of housings which face each other when the light-emitting panel is folded are fixed to each other by magnetism
Implementation Method 2
each of the plurality of housings include a ferromagnet
Implementation Method 3
a light-emitting device using an electroluminescence (EL) phenomenon

AI summary
A light-emitting device can be folded in such a manner that a flexible light-emitting panel is supported by a plurality of housings which are provided spaced from each other and the light-emitting panel is bent so that surfaces of adjacent housings are in contact with each other. Furthermore, in the light-emitting device, in which part or the whole of the housings have magnetism, the two adjacent housings can be fixed to each other by a magnetic force when the light-emitting device is used in a folded state.
