Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing light emitting devices do not allow for independent control of light emitting elements disposed in a row, limiting flexibility in light emission patterns and efficiency.
Innovation Solution
A light emitting device is designed with a base, light emitting elements arranged in two rows and multiple columns, and relay members that enable the light emitting elements to be electrically connected in series, allowing for independent control of two or more groups of light emitting elements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If light emitting elements are disposed in a row and electrically connected in series, then the device can be driven independently in units of rows, but the control flexibility and efficiency are limited
Solution Approach 1:
The light emitting elements are divided into multiple groups (first, second, and third groups) with different connection configurations. Some elements are connected in series while others are connected in parallel, creating segmented control zones that can be independently driven. This segmentation allows flexible control patterns while managing wiring complexity through systematic grouping.
Solution Approach 2:
The patent transitions from a single-row linear arrangement to a two-dimensional matrix arrangement of light emitting elements. This dimensional change enables multiple connection paths and control groups, allowing independent control of different regions while maintaining organized wiring structures through the matrix configuration.
2Productivity
If multiple light emitting elements are connected in series to enable independent row control, then productivity is improved, but the device complexity increases
Solution Approach 1:
The wiring structure is designed to serve multiple functions simultaneously. The same wiring network supports both series connections for independent row control and parallel connections for enhanced flexibility. This multi-functional wiring design enables independent control of multiple groups without proportionally increasing complexity, as the wiring serves dual purposes of control and configuration flexibility.
3Adaptability or versatility
If light emitting elements are arranged in a matrix with multiple connection groups, then adaptability is improved, but the device complexity increases
Solution Approach 1:
The wiring configuration incorporates dynamic control capabilities where different groups of light emitting elements can be selectively activated or deactivated. The first, second, and third connection groups allow for dynamic switching between different emission patterns, enabling the device to adapt to various operational requirements while maintaining a structured wiring framework that manages complexity through systematic organization.
