Solution Overview

Problem

Existing motor vehicle light modules require additional dimensions for positioning and fixing optical devices, which increases the module's size beyond what is necessary for its optical function, posing a challenge in fitting these modules into limited spaces such as headlight or tail light housings.

Innovation Solution

The motor vehicle light module incorporates a wall on the support that separates the light rays from different sources, allowing the optical device to be positioned and fixed directly to this wall. This configuration reduces the need for additional positioning and fixing points, thereby minimizing the module's dimensions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If reinforcements are provided at lateral ends for positioning and fixing optical device, then positioning and fixing reliability is improved, but module dimensions increase beyond optical function needs

Engineering Contradiction:

Improvepositioning and fixing reliabilityVSAvoidmodule dimensions

Core Design Contradiction:

ReliabilityVSLength of stationary object

Solution Approach 1:

The patent merges the positioning/fixing function with the light-separating wall by integrating mounting lugs directly onto the wall structure. This eliminates the need for separate reinforcements at lateral ends, allowing the optical device to be positioned and fixed on the wall itself without increasing module dimensions beyond optical requirements.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The wall serves multiple functions: it separates light from different sources and simultaneously provides positioning and fixing for the optical device through integrated mounting lugs. This multi-functionality eliminates the need for dedicated positioning structures that would increase module size.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Manufacturing precision

If protuberances are added for positioning optical device, then positioning precision is improved, but device complexity increases

Engineering Contradiction:

Improvepositioning precisionVSAvoidstructure complexity

Core Design Contradiction:

Manufacturing precisionVSDevice complexity

Solution Approach 1:

The positioning function is merged into the light-separating wall through integrated mounting lugs. This eliminates the need for separate protuberances, reducing structural complexity while maintaining positioning precision through the wall's inherent geometric definition.

Inventive Principle:

Principle #5Merging (Combining)

AI summary

A motor vehicle light module has at least one first light source intended to emit first light rays and at least one second light source intended to emit second light rays. At least one optical device is configured to deflect at least a part of the first light rays and second light rays, and a support directly or indirectly supports the first light source and the second light source. At least one wall disposed on the support and configured to separate the first light rays from the second light rays, the optical device being positioned on and/or fixed to the wall.
