Solution Overview

Problem

Current DRL light modules have preset optical axis angles, making it difficult to attach them to existing cars with varying front shapes, as they require specific designs to align the light sources parallel to the car axis.

Innovation Solution

An optically adjustable light module with rotatable bodies and a direction adjuster allows for adjustment of the optical axis to be parallel with the car axis, using a housing with fasteners and a sealed interior to secure the position, enabling flexible mounting on different car front shapes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If DRL modules use preset optical axis angles, then the manufacturing and assembly process is simplified, but the adaptability to different car front shapes is reduced

Engineering Contradiction:
Improveassembly processVSAvoidadaptability to different car front shapes
Core Design Contradiction:
Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The patent applies the dynamics principle by making the optical axis angle adjustable rather than fixed. The light module incorporates a rotation mechanism that allows the optical axis to be dynamically adjusted to different angles during installation, enabling adaptation to various car front shapes while maintaining a standardized module design for easy manufacturing.

Inventive Principle:
Principle #15Dynamics

2Adaptability or versatility

If different DRL module designs are created for different car front shapes, then the adaptability is improved, but the device complexity and number of variants increases

Engineering Contradiction:
Improveadaptability to different car front shapesVSAvoidnumber of module designs
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent applies the universality principle by designing a single standardized DRL module that can serve multiple functions and adapt to different installation scenarios. The module includes an adjustable optical axis mechanism that allows one universal design to fit various car front shapes, eliminating the need for multiple specialized designs.

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

AI summary

An optically adjustable light module (10), such as a daytime running lamp of a motor vehicle, includes a housing (12). At least one light source (14) is rotatable about a rotational axis and has an optical axis (16), the light source (14) being disposed in an interior of the housing (12). A direction adjuster (30) is disposed at an exterior of the housing (12). The housing (12) is sealed against moisture. Movement of the direction adjuster (30) rotates the light source (14) about the rotational axis and adjusts a position of the optical axis (16).
