Side-Contact Organic Light-Emitting Element Housing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional light-emitting elements have complex manufacturing processes due to the need for electrical contacts and fixing mechanisms on the upper and lower sides, which increases their size and complicates the back end process.
Innovation Solution
The light-emitting element is designed with the housing surrounding and clamping the side surfaces of the flat light-emitting means, allowing for direct electrical contact and fixing through the side surfaces, eliminating the need for contacts on the upper and lower sides and reducing the overall dimensions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the light-emitting means is fixed in the housing using the upper and/or lower side, then the light-emitting means is securely held, but the emission area is reduced since part of the upper and/or lower side is covered by the fixing
Solution Approach 1:
The patent transitions from fixing the light-emitting means on its upper/lower surfaces (2D plane) to fixing it on its side surfaces (different dimension/orientation). This allows the emission surfaces to remain fully exposed while achieving secure fixation through the housing's clamping action on the side surfaces.
2Reliability
If electrical contacts are formed independently of the housing over the upper and/or lower side, then electrical connection is achieved, but additional cables and female connectors are required which increase installation space
Solution Approach 1:
The patent merges the electrical contact function with the housing structure itself. The housing's inner surface that clamps the side surface also provides the mating contact element, eliminating the need for separate cables and female connectors. This integration reduces installation space while maintaining reliable electrical connection.
Solution Approach 2:
The housing serves multiple functions simultaneously: it provides structural support, secures the light-emitting means through side surface clamping, and establishes electrical contact through the mating contact element on its inner surface. This multi-functionality eliminates the need for separate components.
3Reliability
If fixing and electrical contact are formed independently over the upper and/or lower side, then both functions are achieved, but the back end manufacturing process becomes complicated
Solution Approach 1:
The patent combines the fixing mechanism and electrical contact formation into a single integrated process. The housing's clamping structure and mating contact element are positioned to simultaneously secure the light-emitting means and establish electrical connection during one assembly operation, greatly simplifying the back end manufacturing process.

AI summary
A light-emitting element includes at least one flat light emitter having a first electrical contact portion formed on a side surface, and a housing partially surrounding the side surface of the flat light emitter, the housing including a second electrical contact portion formed on an inner surface of the housing and configured to mate with the first electrical contact portion.
