Solution Overview
Problem
Existing headlights with luminescence diode emitters lack flexibility in implementing various headlight functions, particularly in forming headlight emission cones of different sizes and shapes, due to complex electrical connections and limited control over individual emitters.
Innovation Solution
A headlight design featuring luminescence diode emitters arranged in a matrix with distinct electrical connections, allowing for independent control of each emitter group, reducing the number of electrical connections and enabling flexible realization of different headlight functions by interconnecting emitters in a matrix configuration, allowing for close emitter placement and varied operation modes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If individual luminescence diode emitters are electrically connected and controlled independently, then flexibility in forming headlight emission cones is improved, but the number of electrical connections and device complexity increases
Solution Approach 1:
The luminescence diode emitters are divided into multiple groups (first group, second group, etc.), where emitters within each group are connected in a matrix configuration. This segmentation allows independent control of each group while reducing the total number of electrical connections compared to fully individual control, thereby resolving the contradiction between flexibility and complexity.
Solution Approach 2:
The patent employs a matrix connection structure for electrical connections, transitioning from one-dimensional linear connections to two-dimensional matrix arrangements. This dimensional change enables more efficient routing and reduction of connection lines while maintaining the capability to independently control multiple emitter groups, thus addressing the complexity-f flexibility trade-off.
2Adaptability or versatility
If luminescence diode emitters are arranged closely together, then headlight function flexibility is improved, but electrical isolation between different row and column connections becomes more difficult
Solution Approach 1:
The patent segments the electrical connection system into distinct row connections and column connections that are electrically isolated from each other. This segmentation allows closely spaced emitters to be controlled through orthogonal connection paths, maintaining electrical isolation while enabling close physical arrangement for enhanced flexibility.
Solution Approach 2:
The patent introduces an intermediary control structure where row connections and column connections intersect at emitter locations but remain electrically isolated. This intermediary arrangement acts as a mediator that enables close emitter spacing while maintaining the necessary electrical isolation through the matrix connection architecture.
