Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing light-emitting devices and display devices face challenges in achieving both high portability and browsability, particularly in mobile devices with large display regions, as they often compromise between these two factors.
Innovation Solution
A light-emitting device with a flexible panel supported by multiple housings that are spaced apart and fixed together using magnetic forces, allowing for folding and unfolding without mechanical jigs, thereby enhancing portability and browsability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a large-sized display region is provided to improve browsability, then display area increases, but portability deteriorates due to increased size and weight
Solution Approach 1:
The light-emitting panel is divided into multiple sections that can be folded relative to each other, with housings spaced apart to define fold regions. This segmentation allows the large display area to be collapsed into a compact form for portability while maintaining the full display region when unfolded for browsability.
Solution Approach 2:
The device transitions from a static large flat panel to a dynamic folded structure that can change its configuration between unfolded (for display) and folded (for portability) states. The flexible light-emitting panel enables this dynamic transformation without compromising display quality or portability.
2Stability of the object's composition
If mechanical jigs are used to fix housings during folding, then structural stability improves, but device complexity and component count increase
Solution Approach 1:
The patent replaces mechanical fixing jigs with magnetic fields to hold the housings in the folded state. Magnets embedded in the housings provide automatic attraction and positioning, eliminating the need for complex mechanical fastening mechanisms while maintaining structural stability during folding and transport.
Solution Approach 2:
The magnetic housing structure enables self-fixing during folding - the housings automatically attract and position themselves relative to each other through magnetic force without requiring external mechanical jigs or complex assembly mechanisms, simplifying both the device structure and user operation.
3Weight of moving object
If the light-emitting panel is folded without support structures, then portability improves, but the panel may be damaged during folding and unfolding
Solution Approach 1:
The patent employs a flexible light-emitting panel that can bend and fold without rigid support structures, enabling lightweight portable design. The flexibility of the panel allows it to withstand repeated folding and unfolding cycles while maintaining reliability, eliminating the need for heavy protective support structures that would compromise portability.
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 device provides high portability and browsability by preventing damage during folding and unfolding, reducing power consumption, and allowing seamless large display regions, while simplifying design and reducing component count.
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 and that the ferromagnet be provided in each of the plurality of housings so that magnetic poles of an upper surface and a lower surface of the housing are opposite to each other

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.
