Solution Overview

Problem

Conventional vehicle light devices produce monotonous circular light spots for low and high beam illumination patterns, lacking the ability to project complex patterns such as letters or geometric shapes.

Innovation Solution

The light device incorporates first and second lens modules with integrally formed lens bodies arranged to form predetermined shapes, such as letters or geometric patterns, which project light through specific lens portions to generate unique beam illumination patterns.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Shape

If conventional bulb-shaped light emitting units are used, then the structure is simple and easy to manufacture, but the light spot pattern is monotonous and limited to circular shapes

Engineering Contradiction:
Improvelight spot patternVSAvoidlens module structure
Core Design Contradiction:
ShapeVSDevice complexity

Solution Approach 1:

The light emitting unit is divided into multiple independent lens bodies (first lens body, second lens body, third lens body) arranged in specific patterns. Each lens body can be independently designed with different shapes and optical properties, allowing the system to generate complex light spot patterns while maintaining modular manufacturing simplicity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Different regions of the lens module are assigned different optical functions and shapes. The first lens body creates a first light spot pattern, the second lens body creates a second light spot pattern, and the third lens body creates a third light spot pattern. Each local region has specialized optical properties tailored to its specific function, enabling diverse patterns from a unified structure.

Inventive Principle:
Principle #3Local quality

2Adaptability or versatility

If multiple separate light emitting units are used to create different patterns, then the illumination patterns become diverse, but the device structure becomes complex

Engineering Contradiction:
Improveillumination pattern varietyVSAvoidnumber of light emitting units
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

Multiple lens bodies (first lens body, second lens body, third lens body) are integrated into a single light emitting unit structure. These lens bodies work together to generate multiple distinct light spot patterns (first, second, and third patterns) from one unified device, eliminating the need for separate light emitting units while maintaining pattern diversity.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The light emitting unit is designed as a multi-functional device capable of generating at least three different light spot patterns through its multiple lens bodies. The same structural unit can adapt to different illumination requirements by activating different lens bodies or combinations, providing versatility without requiring multiple specialized units.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Shape

If lens bodies are arranged to form complex predetermined shapes, then the visual interest and functionality are enhanced, but the manufacturing precision requirements increase

Engineering Contradiction:
Improvepredetermined shape patternVSAvoidlens body arrangement precision
Core Design Contradiction:
ShapeVSManufacturing precision

Solution Approach 1:

The complex predetermined shape is segmented into multiple independent lens bodies that can be manufactured separately with standard precision tolerances. Each lens body maintains its specific shape and optical properties independently, reducing the cumulative precision requirements compared to manufacturing a single complex shape as one piece.

Inventive Principle:
Principle #1Segmentation
