Solution Overview

Problem

Existing vehicle lighting systems lack flexibility and safety, as they are often fixed in configuration and characteristics, failing to adapt to varying environmental conditions and regulatory requirements, which can impact visibility and compliance.

Innovation Solution

A method using an electronic display unit at the vehicle's end, controlled by a device that collects data on surroundings to adapt vehicle lights in terms of intensity, size, position, and color, enabling dynamic adjustment of light characteristics to enhance visibility and safety, and comply with different regulations.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If fixed configuration lamps are used, then the lighting system is simple and reliable, but it lacks flexibility to adapt to varying environmental conditions and regulatory requirements

Engineering Contradiction:
Improveadaptability to environmental conditionsVSAvoidlighting system complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent applies dynamics by making the lighting system adjustable and adaptable rather than fixed. The control device dynamically modifies light characteristics (intensity, color temperature, distribution) based on real-time environmental conditions, vehicle speed, and regulatory requirements, resolving the contradiction between adaptability and complexity.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The invention changes physical parameters of the light sources (intensity, color temperature, spatial distribution) to adapt to different conditions. By varying these parameters rather than changing the physical structure, the system achieves high adaptability while maintaining relatively simple hardware architecture.

Inventive Principle:
Principle #35Parameter changes

2Illumination intensity

If fixed characteristics lights are used, then the lighting system is easy to control, but it fails to adapt to varying environmental conditions which impacts visibility

Engineering Contradiction:
ImprovevisibilityVSAvoidcontrol simplicity
Core Design Contradiction:
Illumination intensityVSEase of operation

Solution Approach 1:

The control device receives feedback from sensors about environmental conditions (weather, traffic, illumination levels) and automatically adjusts light characteristics accordingly. This closed-loop feedback system maintains optimal visibility without requiring manual intervention, resolving the contradiction between visibility and control simplicity.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The lighting system performs self-adjustment based on environmental feedback, automatically optimizing its own performance without external control. The system serves itself by autonomously modifying light parameters to maintain visibility, eliminating the need for complex manual control while ensuring adaptability.

Inventive Principle:
Principle #25Self-service

3Adaptability or versatility

If fixed configuration vehicle lights are used, then the system meets basic regulatory requirements, but it cannot comply with different regulatory regimes in different jurisdictions

Engineering Contradiction:
Improvecompliance with regulatory requirementsVSAvoidnumber of light components
Core Design Contradiction:
Adaptability or versatilityVSQuantity of substance

Solution Approach 1:

The patent implements universality by designing a lighting system that can perform multiple functions and comply with different regulatory regimes through software control rather than hardware variation. The same physical light components can be configured to meet different jurisdictional requirements, reducing the need for multiple specialized light assemblies.

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