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

VSEngineering 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

Engineering Contradiction:
Improveflexibility in forming headlight emission conesVSAvoidnumber of electrical connections
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

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.

Inventive Principle:
Principle #1Segmentation

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.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

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

Engineering Contradiction:
Improveheadlight function flexibilityVSAvoidelectrical isolation complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

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.

Inventive Principle:
Principle #1Segmentation

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.

Inventive Principle:
Principle #24Intermediary (Mediator)
