Light Emitting Device Frame Body Stacking for Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional light emitting devices face challenges in miniaturization due to the weakness of frame bodies when their width is reduced, leading to potential instability and falling.
Innovation Solution
The method involves forming a frame body by arranging a first frame body and a second frame body on a substrate, where the second frame body has a larger diameter but the same thickness as the first, to increase the frame body's height while minimizing contact with the substrate, thereby enhancing stability and allowing for a smaller device size.

Engineering Contradiction Analysis
1Volume of moving object
If the frame body width is made narrow to reduce device size, then the device can be made smaller, but the frame body becomes weak and may fall over
Solution Approach 1:
The patent transitions the frame body from a single-layer planar structure to a multi-layer stacked structure. By adding the vertical dimension with multiple frame bodies (first frame body and second frame body) stacked on the substrate, the structure gains enhanced mechanical strength and stability without increasing the horizontal footprint, thus resolving the contradiction between device miniaturization and frame body strength.
Solution Approach 2:
The frame body is divided into multiple independent frame body units (first frame body and second frame body) that are stacked and fixed together. Each frame body can be manufactured separately and then assembled, allowing the structure to achieve greater overall strength through the stacked configuration while maintaining a compact horizontal profile.
2Area of stationary object
If the frame body width is made narrow, then the device size is reduced, but the contact area with substrate decreases leading to instability
Solution Approach 1:
The patent compensates for reduced horizontal contact area by utilizing the vertical dimension. Multiple frame bodies stacked on the substrate create a distributed contact structure where the cumulative contact area of multiple smaller frame bodies provides sufficient stability, even when each individual frame body has a narrow width.

AI summary
A method for manufacturing a light emitting device includes: providing a substrate including a placement region for placing a light emitting element on a top surface; mounting the light emitting element in the placement region; and forming a frame body surrounding the placement region on the substrate. The step of forming the frame body is performed by arranging a first frame body and second frame body on the substrate to surround the placement region. The second frame body have a larger diameter than the first frame body, and have the same thickness as the first frame body.
