Solution Overview

Problem

Existing automotive vehicle light assemblies require complete replacement upon damage or failure of a component, leading to increased repair costs.

Innovation Solution

A modular design with a main housing and a luminous device that allows for separate replacement of the outer lens and main housing or luminous device, maintaining the assembly's seal and functionality.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the light assembly is designed as a hermetically sealed unit, then the reliability and protection against water ingress is improved, but the ease of repair deteriorates because the entire assembly must be replaced upon component failure

Engineering Contradiction:
Improveseal integrityVSAvoidrepair cost
Core Design Contradiction:
ReliabilityVSEase of repair

Solution Approach 1:

The light assembly is divided into separate modular components: a main housing containing electronic components and a removable luminous device with light sources. This segmentation allows the luminous device to be independently replaced without replacing the entire sealed assembly, reducing repair costs while maintaining seal integrity through the reversible fastening mechanism between modules

Inventive Principle:
Principle #1Segmentation

2Reliability

If the light assembly is designed as a hermetically sealed unit, then the reliability and protection against water ingress is improved, but the ease of repair deteriorates because the entire assembly must be replaced upon component failure

Engineering Contradiction:
Improveseal integrityVSAvoidassembly structure
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The light assembly is divided into separate modular components: a main housing containing electronic components and a removable luminous device with light sources. This segmentation allows the luminous device to be independently replaced without replacing the entire sealed assembly, reducing repair costs while maintaining seal integrity through the reversible fastening mechanism between modules

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The fastening mechanism transitions from a permanent irreversible seal to a reversible dynamic connection. The luminous device can be selectively removed and reattached through the reversible fastening system, enabling maintenance and replacement operations while maintaining hermetic sealing when assembled, thus balancing reliability with serviceability

Inventive Principle:
Principle #15Dynamics

3Reliability

If the light assembly uses irreversible fastening for the outer lens, then the seal integrity is improved, but the ease of repair deteriorates because the lens cannot be replaced

AI summary

The invention relates to a light assembly including a main housing with a front opening and a rear opening facing at least a part of the front opening, a luminous device with a secondary housing, and an outer lens sealingly closing the front opening of the main housing. The luminous device can be seated in the rear opening, and the secondary housing is sealingly and reversibly fastened to the main housing. In the event of a failure of a component of a luminous device of a light assembly and/or in the event of impacts damaging a part of the light assembly, the light assembly according to the invention requires just one part to be replaced, for example, only the outer lens and the main housing or only the luminous device need be replaced.
