Solution Overview

Problem

Conventional vehicle lamps occupy excessive space and fail to satisfy design requirements due to differing light emitting surfaces when multiple functions are activated, leading to inadequate design differentiation and inefficient use of space.

Innovation Solution

A lamp module with multiple light sources forming distinct light distribution patterns, utilizing a light guide with recessed areas and an optic part to direct light output from both sources, allowing for shared light emitting surfaces and improved design differentiation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple separate lamps are mounted on the vehicle to provide different lighting functions, then each lamp can have its dedicated light emitting surface, but the total space occupied by the lamps becomes excessively large

Engineering Contradiction:

Improvelighting function versatilityVSAvoidspace occupied by lamps

Core Design Contradiction:

Adaptability or versatilityVSArea of stationary object

Solution Approach 1:

The patent combines multiple separate lamps into a single integrated lamp module that houses multiple light sources (first and second light sources) within one structure. This merging approach allows the module to occupy less space while still providing multiple lighting functions through different light distribution patterns generated by the respective light sources

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The lamp module is designed as a universal structure that can perform multiple lighting functions simultaneously. The light guide is configured to distribute light from different light sources to create distinct light distribution patterns, enabling one lamp module to replace multiple dedicated lamps while maintaining functional versatility

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If multiple separate lamps are mounted on the vehicle to provide different lighting functions, then each lamp can operate independently, but the design differentiation is insufficient when lamps are switched on

Engineering Contradiction:

Improvelighting function differentiationVSAvoidlight emitting surface uniformity

Core Design Contradiction:

Adaptability or versatilityVSShape

Solution Approach 1:

The light guide incorporates different optical structures at different locations to generate distinct light distribution patterns. The first light source and second light source are positioned and configured differently within the module, with the light guide directing their light outputs to create differentiated illumination patterns, thus achieving design differentiation while maintaining uniform light emitting surface appearance

Inventive Principle:

Principle #3Local quality

3Area of stationary object

If a single lamp module with multiple light sources is used to share one light emitting surface, then space usage is optimized, but the light distribution control becomes more complex

Engineering Contradiction:

Improvespace occupied by lampsVSAvoidlight distribution control structure

Core Design Contradiction:

Area of stationary objectVSDevice complexity

Solution Approach 1:

The light guide serves as an intermediary component that simplifies light distribution control. It receives light from multiple light sources and uses integrated optical structures (including the first recessed area and optic part) to automatically direct and shape the light into different distribution patterns, reducing the complexity of control mechanisms while achieving differentiated light output

Inventive Principle:

Principle #24Intermediary (Mediator)
