Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing three-dimensional light-emitting devices lack the ability to provide a stereoscopic feeling, which is essential for creating depth and visual interest in designs such as automobile tail lamps and display devices.
Innovation Solution
A light-emitting device comprising a first and second light-emitting member, each with a first and second surface, and regions that are strategically positioned to create a stereoscopic effect, utilizing an OLED panel with high design flexibility, where the first region of one member is located on the second surface of the other, and the second region is on the first surface, allowing for conspicuous depth and aesthetic appeal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If conventional three-dimensional light-emitting device structures are used, then device complexity is reduced, but the ability to provide a stereoscopic feeling is insufficient
Solution Approach 1:
The patent applies nesting by positioning the first light-emitting member inside the second light-emitting member, with the first member located on the second surface side of the second member. This nested configuration creates a stereoscopic effect with depth perception while maintaining a compact structure, avoiding the need for complex external arrangements.
Solution Approach 2:
The patent utilizes the third dimension (depth) by positioning light-emitting regions at different depths within the device structure. The first light-emitting member is placed on the second surface side while the second member's light-emitting region is on the first surface side, creating layered depth perception that provides a stereoscopic feeling without increasing lateral complexity.
2Shape
If light-emitting members are positioned close together to create depth, then stereoscopic feeling is improved, but friction and damage between members increases
Solution Approach 1:
The nested configuration allows light-emitting members to be positioned at different depths with natural spatial separation. The first member is nested within the volume of the second member but positioned on the second surface side, creating depth perception while maintaining sufficient spacing to prevent friction and mechanical damage between the members.
3Adaptability or versatility
If OLED panels are used to provide design flexibility, then shape freedom is improved, but manufacturing complexity increases
Solution Approach 1:
The patent merges multiple light-emitting members into a single integrated device structure with unified housing. The first and second light-emitting members are positioned within the same housing structure, allowing the OLED panels to provide shape flexibility while the integrated housing simplifies manufacturing by treating the assembly as a single unit rather than separate components.
