Vehicle Decorative Illumination Component Design Unity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicle decorative components with illumination functions lack design unity with surrounding elements, have inefficient light transmission, and suffer from assembly issues such as backlash and increased component costs due to separate noise suppression methods, and require complex installation processes.
Innovation Solution
A vehicle decorative component with a light emitting region that includes an irradiation body, a transmissive body, and a decorative layer, where the decorative layer's design matches the non-light emitting region, allowing for efficient light transmission and assembly without additional noise suppression members, and a simplified installation method that aligns the components for proper alignment and fixation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a conventional courtesy lamp with a milky white lens is used for illumination, then the illumination function is achieved, but the design unity with peripheral members is poor
Solution Approach 1:
The patent applies color changes by making the lens transparent or translucent instead of opaque milky white, allowing the peripheral members' color and design to show through. This enables the illumination component to blend with the surrounding interior members while still providing the required lighting function.
Solution Approach 2:
The patent applies local quality by making only the light-transmitting portions transparent or translucent, while other portions of the peripheral members can maintain their original decorative properties. This allows different regions to have different optical properties suited to their specific functions.
2Reliability
If separate noise suppression members are added to fill gaps between light guiding body and holder, then backlash is suppressed, but device complexity and cost increase
Solution Approach 1:
The patent merges the noise suppression function into the holder structure itself by providing a fitting portion that directly contacts the light guiding body. This integration eliminates the need for separate noise suppression members while achieving the same backlash suppression effect.
Solution Approach 2:
The holder structure serves dual purposes: it provides mechanical support and simultaneously suppresses backlash through its fitting portion design. The structure self-regulates the gap between components without requiring additional dedicated noise suppression elements.
3Volume of moving object
If the light source and light guiding body are assembled at adjacent positions, then the structure is compact, but light incidence efficiency is reduced
Solution Approach 1:
The patent positions the light source and light guiding body such that light enters from the side rather than from the end, utilizing a different spatial dimension for light incidence. This side-entry configuration allows compact arrangement while maintaining efficient light coupling through proper angular alignment.

AI summary
Provided is a vehicle decorative component capable of functioning as a decorating illumination while harmonizing with peripheral members at the time of lights-out from a view of improving a design property. In a light emitting ornament 1 having a light emitting region 1a that emits light and a non-light emitting region 1b adjacent to the light emitting region 1a, the light emitting region 1a includes an irradiation body including a lamp 31 and a light guiding body 32, an ornament base material 11 through which the light emitted from the irradiation body is transmitted at a front position of the irradiation body, and a decorative film 12 formed at a front position of the ornament base material 11 and exposed on the vehicle interior side, the decorative film through which the light transmitted through the ornament base material 11 is capable of being transmitted, and a decoration style of a surface of the decorative film 12 exposed on the vehicle interior side is the same as a decoration style of a surface of the non-light emitting region 1b.
