Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional light-emitting devices with electronic components attached to installation surfaces experience instability due to unevenness, leading to potential gaps between the device and the surface.
Innovation Solution
A light-emitting device design featuring a surface-light-emitting unit with a light-emitting and non-light-emitting surface, a base member with flush surfaces for electronic components, and flexible sheets for stable installation, ensuring the device can be securely attached to various surfaces without creating gaps.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If electronic components are mounted on the light-emitting device, then the device functionality is improved, but installation stability deteriorates due to unevenness
Solution Approach 1:
The patent applies flexible sheets (first sheet and second sheet) to cover the electronic components and create a flush installation surface. The first sheet covers the electronic component on the base member, and the second sheet covers both the surface-light-emitting unit and electronic component, enabling the device to be installed stably on the installation surface without gaps while maintaining electronic component functionality
2Adaptability or versatility
If electronic components are mounted on the base member, then device functionality is improved, but gaps are formed between device and installation surface
Solution Approach 1:
The patent uses flexible sheets to create a smooth outer surface that conforms to the installation surface. The first sheet is disposed on the electronic component, and the second sheet covers both the surface-light-emitting unit and electronic component, eliminating gaps and creating an even installation surface while preserving device functionality
Solution Approach 2:
The patent transitions from a two-dimensional electronic component layout to a three-dimensional encapsulated structure by covering components with flexible sheets. This dimensional change allows the components to be mounted on the base member while maintaining a flush, gap-free installation surface through the added protective layer
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 allows for stable installation of the light-emitting device on surfaces, preventing gaps and ensuring evenness, while maintaining flexibility for curved or flat installations.
Implementation Method 1
The surface-light-emitting unit (21) has a light-emitting surface (21a) and a non-light-emitting surface (21b) which is disposed on a back side of the light-emitting surface, and emits light from the light-emitting surface

AI summary
A light-emitting device includes a surface-light-emitting unit, a substrate, a holding sheet, and a sealing sheet. The surface-light-emitting unit has a light-emitting surface and a non-light-emitting surface, and emits light from the light-emitting surface. The substrate has a mounting surface and a non-mounting surface provided to be flush with the light-emitting surface, and has a power source mounted on the mounting surface. The holding sheet is provided to face the non-mounting surface and the light-emitting surface provided to be flush with the non-mounting surface. The sealing sheet is disposed on the side opposite to the holding sheet with respect to the surface-light-emitting unit and the substrate, and provided to cover the surface-light-emitting unit and the power source. The light-emitting device is disposed so that the holding sheet comes to the installation surface side. With such a structure, the light-emitting device that can be stably disposed on the installation surface is provided.
