Solution Overview

Problem

Existing optical modules suffer from uncontrollable light mixing, leading to the formation of single-color light rendering due to the absence of light-blocking portions in the light guide member.

Innovation Solution

Incorporating a light guide structure with light-blocking portions between adjacent light guide strips to prevent light mixing, allowing separate emission of light from multiple sub-light sources to different areas of the light-transmitting unit, and utilizing a light scatterer to enhance rendering effects.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If a light guide member is used without light-blocking portions, then the structure is simple, but light mixing occurs causing uncontrollable transmitted light and single-color rendering

Engineering Contradiction:
Improvestructure simplicityVSAvoidlight control precision
Core Design Contradiction:
Device complexityVSManufacturing precision

Solution Approach 1:

The light guide member is segmented into multiple light guide strips with light-blocking portions between them. This segmentation prevents light from adjacent strips from mixing, allowing each sub-light source to control its corresponding light guide strip independently, thereby achieving precise light control while maintaining relatively simple structure.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Light-blocking portions are introduced as intermediary elements between adjacent light guide strips. These portions act as barriers that prevent light from one strip from interfering with adjacent strips, enabling independent control of each light guide strip while maintaining the overall simplicity of the light guide member structure.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Manufacturing precision

If light-blocking portions are added between light guide strips, then light mixing is prevented and multi-color rendering is achieved, but the structure becomes more complex

Engineering Contradiction:
Improvelight control precisionVSAvoidstructure complexity
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The light guide member is divided into multiple independent light guide strips separated by light-blocking portions. This segmentation enables precise control of each strip's light output while the modular design keeps the overall structure manageable and not excessively complex.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Light-blocking portions are strategically placed only where needed - between adjacent light guide strips - rather than throughout the entire structure. This localized approach provides the necessary light control precision exactly where light mixing occurs, without adding unnecessary complexity to other areas of the structure.

Inventive Principle:
Principle #3Local quality

3Device complexity

If multiple sub-light sources emit light simultaneously without separation, then the light source configuration is simple, but light mixing occurs preventing controlled multi-color emission

Engineering Contradiction:
Improvelight source configuration simplicityVSAvoidlight color rendering capability
Core Design Contradiction:
Device complexityVSAdaptability or versatility

Solution Approach 1:

The light guide member is segmented into multiple light guide strips, each corresponding to a sub-light source. This segmentation allows each sub-light source to emit its specific color light through its dedicated strip without interference, enabling independent control of multiple colors while maintaining a simple configuration of sub-light sources.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Light-blocking portions serve as intermediaries that isolate light from different sub-light sources. This isolation enables each sub-light source to contribute its specific color to the overall light output without mixing with adjacent colors, providing versatile multi-color rendering capability while keeping the light source configuration simple.

Inventive Principle:
Principle #24Intermediary (Mediator)
