Solution Overview

Problem

Existing lighting modules in motor vehicles face accessibility issues during replacement due to space constraints and mounting direction limitations, making it difficult to remove and replace components like light sources efficiently.

Innovation Solution

A lighting module with dual attachment means allowing vertical and longitudinal mounting, enabling easy replacement by alternating between first and second attachment methods, ensuring stability and accessibility.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a single mounting direction is used for the lighting module, then the mounting structure is simple, but the accessibility for replacement is poor due to space constraints

Engineering Contradiction:
ImproveAccessibility for replacementVSAvoidMounting structure complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The lighting module is segmented into two independent attachment means (first attachment means and second attachment means), each capable of mounting in different directions. This segmentation allows the module to be mounted vertically or longitudinally depending on space availability, improving accessibility for replacement without requiring a completely complex mounting system.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The lighting module is designed with multi-functionality by incorporating both first and second attachment means that can alternatively fix the module in different directions (vertical or longitudinal). This universal mounting capability allows the same lighting module to adapt to different installation spaces and maintenance requirements, resolving the contradiction between operational ease and structural complexity.

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

2Adaptability or versatility

If the lighting module is fixed in a fixed orientation, then the mounting is stable, but the adaptability to different mounting directions is limited

Engineering Contradiction:
ImproveMounting direction adaptabilityVSAvoidMounting stability
Core Design Contradiction:
Adaptability or versatilityVSStability of the object's composition

Solution Approach 1:

The lighting module employs a dynamic mounting system where the mounting plate can alternatively connect to either the first attachment means or the second attachment means, changing the orientation from vertical to longitudinal or vice versa. This dynamic adaptability allows the system to adjust to different mounting directions while maintaining stable fixation through the alternative attachment mechanisms.

Inventive Principle:
Principle #15Dynamics
