Solution Overview

Problem

Existing vehicle courtesy lighting systems, particularly those in side mirrors and doors, fail to uniformly illuminate the area around the vehicle regardless of door position, leading to potential obstacles being overlooked, and are prone to damage and soiling, which reduces their effectiveness.

Innovation Solution

A trim component with a wall, through-openings, and an adjustable lighting device that can be moved between open and closed positions to control light emission, with light guides and decoupling sections that are protected from external influences, allowing for uniform illumination when the vehicle is stationary and minimizing contamination when in use.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Area of stationary object

If LEDs are mounted on the side sill to illuminate the area around the vehicle, then the illuminated area is enlarged and uniform illumination is achieved, but the LEDs are exposed to damage from stone chips and other impacts

Engineering Contradiction:
Improveilluminated areaVSAvoidLED protection from damage
Core Design Contradiction:
Area of stationary objectVSReliability

Solution Approach 1:

The lighting device is nested within the fairing component's interior space, with LEDs positioned inside the wall structure. The wall with through-openings provides protective enclosure while allowing light to pass through when needed, effectively nesting the vulnerable LED components within a protective structure.

Inventive Principle:
Principle #7Nested doll (Nesting)

Solution Approach 2:

The wall with through-openings acts as an intermediary structure between the internal LED light source and the external environment. This intermediary element allows light transmission while providing mechanical protection, mediating between the need for illumination and the need for component protection.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Area of stationary object

If LEDs protrude from the side panels to provide illumination, then the illuminated area is increased, but the LEDs become dirty quickly during vehicle operation

Engineering Contradiction:
Improveilluminated areaVSAvoidsoiling of LEDs
Core Design Contradiction:
Area of stationary objectVSObject-affected harmful factors

Solution Approach 1:

The lighting device is nested within the fairing component's interior space, with LEDs positioned inside the wall structure. This nesting arrangement protects the LEDs from direct exposure to dust and moisture while still enabling light transmission through the through-openings when required.

Inventive Principle:
Principle #7Nested doll (Nesting)

Solution Approach 2:

The wall with through-openings serves as an intermediary barrier that filters environmental contaminants while allowing light passage. This intermediary structure protects the LEDs from direct contact with dirt and moisture during vehicle operation.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Illumination intensity

If the lighting device is positioned to illuminate the area around the vehicle, then effective illumination is achieved, but the lighting device is exposed to damage and soiling

Engineering Contradiction:
Improveillumination effectivenessVSAvoidlighting device protection
Core Design Contradiction:
Illumination intensityVSReliability

Solution Approach 1:

The lighting device is nested within the fairing component's interior space, positioned inside the wall structure with access to through-openings. This nesting provides protective enclosure while maintaining illumination effectiveness through strategic positioning of the light source relative to the openings.

Inventive Principle:
Principle #7Nested doll (Nesting)

Solution Approach 2:

The wall structure with through-openings acts as an intermediary protective barrier, allowing the lighting device to maintain effective illumination while being shielded from environmental hazards during vehicle operation.

Inventive Principle:
Principle #24Intermediary (Mediator)

4Area of stationary object

If approach lighting is mounted in side mirrors and door handles, then the immediate area around the vehicle is illuminated, but the illuminated area depends on door position

Engineering Contradiction:
Improveilluminated areaVSAvoidillumination consistency
Core Design Contradiction:
Area of stationary objectVSAdaptability or versatility

Solution Approach 1:

The fairing component integrates multiple functions: it provides structural cladding, contains protective enclosure for the lighting device, and enables consistent illumination through its through-openings. This multi-functional design ensures uniform illumination regardless of door position, as the lighting device remains in a fixed position relative to the vehicle body.

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