Solution Overview

Problem

Existing vehicle lamps lack precise control over light output, limiting visibility and the ability to convey complex information effectively to drivers and other road users.

Innovation Solution

A vehicle lamp system that includes a lamp module, an interface unit to receive driving situation information, and a processor to control the resolution of output light based on this information, allowing for adjustable light distribution to enhance visibility and information transmission.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If uniform light output is used across the light distribution area, then the lamp structure is simple and easy to manufacture, but precise control of light output and resolution cannot be achieved

Engineering Contradiction:
Improvelight control precisionVSAvoidlamp structure complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The light distribution area is divided into multiple control regions, with different resolution levels assigned to different regions. The processor controls the lamp module to output light at different resolutions in different regions, enabling precise light control where needed while maintaining simplicity in other areas.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Different resolution levels are applied to different regions of the light distribution area based on local requirements. High resolution is applied to regions requiring precise light control (such as areas with objects detected by the interface unit), while lower resolution is used in regions where precise control is not necessary, optimizing both control precision and system complexity.

Inventive Principle:
Principle #3Local quality

2Illumination intensity

If high resolution light output is used throughout the entire light distribution area, then visibility and information transmission are maximized, but energy consumption increases

Engineering Contradiction:
Improvevisibility qualityVSAvoidenergy consumption
Core Design Contradiction:
Illumination intensityVSUse of energy by moving object

Solution Approach 1:

High resolution light output is applied only to partial regions where objects are detected or where precise light control is needed, rather than uniformly across the entire light distribution area. The processor receives object information from the interface unit and dynamically adjusts the resolution level in different regions, reducing energy consumption while maintaining visibility quality where necessary.

Inventive Principle:
Principle #16Partial or excessive action

3Adaptability or versatility

If fixed resolution light output is used, then the lamp system is simple to operate, but adaptability to different driving situations is limited

Engineering Contradiction:
Improvedriving situation adaptabilityVSAvoidsystem operation simplicity
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The lamp system dynamically adjusts the resolution of light output in different regions based on driving situation information received by the interface unit. The processor automatically modifies the light distribution pattern in real-time according to detected objects and environmental conditions, providing adaptability without requiring manual operation complexity.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The interface unit receives information about objects and driving situations, providing feedback to the processor. The processor uses this feedback to automatically adjust the light output resolution and distribution pattern, enabling the system to adapt to different driving situations while maintaining ease of operation through automatic control.

Inventive Principle:
Principle #23Feedback
