Vehicle Emblem Device Indirect Illumination Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vehicle emblems mounted on air bag covers often weaken the surrounding structure and fail to provide effective indirect illumination due to their design and material usage.
Innovation Solution
An emblem device comprising an air bag cover, a substrate with a light source, a light guide plate, and an emblem with protrusions that securely mount to the cover, allowing indirect illumination through a space between the cover and the emblem, enhancing structural strength and illumination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the emblem is assembled inside the air bag cover, then the emblem can be mounted, but surrounding parts may be damaged due to interference with the emblem and the air bag cover may be weakened in strength
Solution Approach 1:
The emblem mounting structure transitions from a two-dimensional planar assembly to a three-dimensional configuration by creating a space between the emblem and the air bag cover. The emblem is positioned on the outer surface of the air bag cover rather than being embedded inside, and mounting protrusions extend through the cover to secure the emblem while maintaining structural integrity
Solution Approach 2:
The mounting protrusions are nested within the air bag cover structure, extending through the cover to secure the emblem. This nested configuration allows the emblem to be firmly attached while the protrusions remain integrated within the cover's structural framework, preventing strength degradation
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution enables indirect illumination of the emblem's surroundings while improving the structural integrity of the air bag cover with a simple and secure mounting system, preventing separation of components.
Implementation Method 1
a light guide plate mounted outside the air bag cover and configured to diffuse the light emitted from the light source
Data Source
AI summary
An emblem device includes an air bag cover, a substrate mounted inside the air bag cover, a light source mounted on the substrate and configured to emit light, a light guide plate mounted outside the air bag cover and configured to diffuse the light emitted from the light source, and an emblem located in front of the light guide plate and configured to cover a part of the light guide plate. The light emitted from the light guide plate is emitted in front of the emblem through a space formed between the air bag cover and the emblem.
