Organic EL Panel Mounting with Raised Circuit Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The thickness of organic EL panels increases due to the mounting of circuit boards, compromising their thinness, and existing mounting systems for these panels are cumbersome and costly to manufacture, especially when adapting to different wall environments.
Innovation Solution
An illumination device with an organic EL panel and a mounting member that includes a raised part to protect the circuit board and engage with the panel, allowing for easy attachment and detachment without screws, and a dual-surface attachment mechanism to accommodate various wall types, reducing manufacturing costs and complexity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a circuit board is mounted on the rear face side of the organic EL panel, then the panel can provide color tuning control and dimming control functions, but the thickness of the panel increases, compromising the advantage of thinness
Solution Approach 1:
The patent moves the circuit board from the rear face side to the front face side of the organic EL panel, utilizing the front face space instead. This dimensional relocation allows the panel to maintain its thinness while still providing color tuning and dimming control functions through the circuit board mounted on the emission surface side.
2Reliability
If a conventional mounting structure with bolts and screws is used to attach the organic EL panel, then the panel can be securely fixed, but the replacement process becomes troublesome and time-consuming
Solution Approach 1:
The patent divides the attachment system into separate engagement parts: a first engagement part on the mounting member and a second engagement part on the organic EL panel. These segmented components can be easily engaged and disengaged without tools, allowing secure attachment while enabling simple replacement by merely separating the two engagement parts.
Solution Approach 2:
The patent replaces the traditional mechanical fastening system (bolts, screws, and screwdrivers) with a simplified engagement system that uses complementary geometric shapes or interlocking features. This substitution eliminates the need for tools and complex mechanical fasteners, making the attachment secure yet the replacement trivial.
3Adaptability or versatility
If a mounting structure designed for specific wall types is used, then the attachment can be optimized for that wall type, but the manufacturing cost increases when multiple mounting structures are needed for different wall environments
Solution Approach 1:
The patent designs the mounting member with a universal first engagement part that can adapt to various wall types (such as concrete, brick, or drywall) through different mounting methods (screws, adhesives, or mechanical anchors). This single universal design eliminates the need to manufacture separate mounting structures for each wall type, reducing manufacturing costs while maintaining optimization for different applications.

AI summary
The present invention provides an illumination device in which an organic EL panel is detachable from a mounting member; the panel has a panel body and a fixing member. The panel body has an emission surface on its front and a circuit board on its rear. The fixing member has a main body and a raised part that is disposed on a rear of the panel and raised with respect to the main body to circumvent the circuit board and to protect the circuit board. The raised part includes a raised-side engagement part protruding in a direction crossing a raised direction. The mounting member has an attachment side main body and an attachment side engagement part. The attachment side engagement part extends from the attachment side main body to form a step. The engagement parts engage together when the panel is attached to the mounting member.
