VSEngineering Contradiction Analysis

1Reliability

If conventional signal light modules with multiple LEDs, reflectors, and light wave conductors are used, then the signal light can be made visible to road users, but the configuration becomes complex and expensive

Engineering Contradiction:
Improvevisibility of signal lightVSAvoidconfiguration of signal light module
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent merges multiple components (LED, reflector, light wave conductor, lens) into a single integrated molded lighting element. The LED is positioned within a molded body that incorporates the reflector geometry and light distribution features directly into the plastic structure, eliminating the need for separate assemblies and reducing overall complexity while maintaining visibility requirements

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The molded lighting element serves multiple functions simultaneously: the LED provides illumination, the molded body acts as a reflector, the integrated geometry controls light distribution, and the overall structure serves as both the light source housing and optical element. This multi-functionality reduces the number of separate components needed

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

2Reliability

If additional LEDs are integrated at the outermost edge of the exterior mirror, then the signal light becomes recognizable to road users beside or behind the vehicle, but the configuration becomes more complex

Engineering Contradiction:
Improverecognizability of signal lightVSAvoidsignal light module configuration
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent combines the LED light source with the exterior mirror housing into a single integrated unit. The LED is positioned at the outermost edge of the mirror and is molded directly into the housing structure, eliminating the need for separate signal light modules and their associated mounting, wiring, and adjustment mechanisms

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The molded lighting element is designed to be self-contained, with the LED, reflector, and light distribution features all integrated into a single piece. This self-service design eliminates the need for complex assembly, adjustment, and maintenance of separate components

Inventive Principle:
Principle #25Self-service
