Solution Overview

Problem

Conventional side turn signal lamps mounted on rearview mirrors create multiple styling parting lines and are susceptible to wind noise.

Innovation Solution

A side turn signal lamp mounting assembly that integrates a mounting cover plate with light-transmitting regions and a turn signal lamp component, positioning the lamp component inside the cover plate to reduce exposure and wind noise, while ensuring light emission through aligned light-transmitting regions for enhanced visibility.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If the turn signal lamp component is mounted on the rearview mirror, then the turn signal function is achieved, but multiple styling parting lines are created and wind noise is generated

Engineering Contradiction:
Improveturn signal lamp installationVSAvoidwind noise and styling parting lines
Core Design Contradiction:
Ease of manufactureVSObject-generated harmful factors

Solution Approach 1:

The turn signal lamp component is extracted from the rearview mirror and relocated to the door body, eliminating the source of wind noise and excessive parting lines on the rearview mirror while maintaining the turn signal function

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The turn signal lamp component is integrated into the door body structure through the mounting cover plate, combining the lighting function with the existing door styling lines to reduce overall parting lines

Inventive Principle:
Principle #5Merging (Combining)

2Illumination intensity

If the turn signal lamp component is exposed on the vehicle body surface, then the turn signal is visible, but the component is susceptible to wind noise and reduced service life

Engineering Contradiction:
Improveturn signal visibilityVSAvoidservice life and wind resistance
Core Design Contradiction:
Illumination intensityVSReliability

Solution Approach 1:

The turn signal lamp component is nested within the mounting cover plate, which provides protective coverage while maintaining light transmission functionality through the light-transmitting region

Inventive Principle:
Principle #7Nested doll (Nesting)

Solution Approach 2:

The mounting cover plate with light-transmitting region acts as a protective shell that shields the turn signal lamp component from wind noise and environmental damage while allowing light to pass through for visibility

Inventive Principle:
Principle #30Flexible shells and thin films

3Reliability

If the mounting cover plate covers the turn signal lamp component, then wind noise is reduced and service life is extended, but light emission may be obstructed

Engineering Contradiction:
Improveservice life and wind protectionVSAvoidlight emission capability
Core Design Contradiction:
ReliabilityVSIllumination intensity

Solution Approach 1:

The mounting cover plate is designed with a light-transmitting region that provides localized transparency where light emission is needed, while other portions of the cover plate provide protective coverage, creating different functional zones in different locations of the same component

Inventive Principle:
Principle #3Local quality
