Solution Overview

Problem

Current vehicle light systems lack the ability to efficiently illuminate light in multiple directions simultaneously and prevent light bleeding through textured regions, which can cause unwanted flash during manufacturing and affect the appearance of the light system.

Innovation Solution

A bi-directional light system with a light blade that directs light in two perpendicular directions, utilizing a controller to manage individual light sources and prevent light from passing through textured regions, ensuring each portion of the light system remains visibly separate and preventing light from bleeding.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If a single lens is used to provide light in multiple directions, then the device complexity is reduced, but light bleeding through textured regions occurs causing manufacturing defects

Engineering Contradiction:

Improvelight system structureVSAvoidlight emission control

Core Design Contradiction:

Device complexityVSManufacturing precision

Solution Approach 1:

The patent divides the single lens into multiple separate light emitting regions, each with its own textured surface. This segmentation allows independent control of light emission from each region, preventing light bleeding between regions while maintaining a relatively simple overall structure.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Each light emitting region has its own textured surface with specific local properties. The texture in each region is optimized for that particular light source, allowing precise control over light emission patterns and preventing unwanted light propagation to adjacent regions.

Inventive Principle:

Principle #3Local quality

2Illumination intensity

If light is directed in multiple directions simultaneously, then the illumination coverage is improved, but light from one region illuminates adjacent regions causing visual interference

Engineering Contradiction:

Improvelight coverageVSAvoidlight interference

Core Design Contradiction:

Illumination intensityVSObject-affected harmful factors

Solution Approach 1:

The lens is segmented into multiple independent light emitting regions, each directing light in specific directions. This segmentation ensures that light from one region does not interfere with adjacent regions, eliminating visual interference while maintaining comprehensive illumination coverage.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The textured surface acts as an intermediary between the light source and the external environment. It controls and directs light propagation, allowing light to be emitted in multiple directions from each region while preventing light from one region from reaching adjacent regions.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Adaptability or versatility

If a bi-directional light system is implemented, then the versatility of the light system is improved, but the device complexity increases

Engineering Contradiction:

Improvelight direction controlVSAvoidlight system structure

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

Each light emitting region in the lens serves multiple functions: it can emit light in different directions, be independently controlled, and prevent light interference with adjacent regions. This multi-functionality increases versatility without requiring separate systems for each function.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

Multiple light emitting regions and their associated textured surfaces are merged into a single integrated lens structure. This combination provides bi-directional and multi-directional light control capabilities while maintaining a simple unified structure rather than requiring separate components.

Inventive Principle:

Principle #5Merging (Combining)
