Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle lighting devices, such as taillights and rear-view devices, face challenges in providing both aesthetic appeal and meeting technical specifications, often requiring multiple components and being complex to adapt to vehicle styling.
Innovation Solution
A lighting device for rear-view devices featuring at least two light sources of different colors, integrated with lightguides and a reflective element, which creates direct and indirect light effects, along with a pattern generating element to enhance aesthetic appeal and styling, allowing for better packaging and hidden light source placement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple components are used to provide both aesthetic appeal and technical specifications, then the lighting functionality is improved, but the device complexity increases
Solution Approach 1:
The patent combines multiple light sources (first and second light sources with different colors) and lightguides (first and second lightguides) into a single integrated lighting device housing. The supporting element integrates mounting functions for both light sources and lightguides, consolidating what would traditionally require separate components into one unified structure that provides both aesthetic lighting patterns and functional turn signal capabilities.
Solution Approach 2:
The lighting device is designed to perform multiple functions simultaneously: it provides turn light signals through colored light sources, creates aesthetic light patterns through the transparent lens and reflective elements, and allows for flexible packaging arrangements. The housing supports both direct and indirect light emission modes, making the device universally applicable for various lighting requirements in a single integrated unit.
2Shape
If light sources are hidden for aesthetic purposes, then the styling appeal is improved, but the ease of installation and maintenance deteriorates
Solution Approach 1:
The lighting device is divided into detachable modules: the housing can be separated from the supporting element, and light sources can be independently accessed. This segmentation allows the light sources to remain hidden within the housing structure for aesthetic purposes while enabling easy access for installation and maintenance by detaching the housing or removing the supporting element.
Solution Approach 2:
The transparent lens acts as an intermediary element that allows light to pass through while hiding the light sources from direct view. The lens maintains the aesthetic appearance by concealing the light sources, yet the modular design of the housing and supporting element provides access pathways for installation and maintenance operations.
3Volume of moving object
If integrated lighting system is used, then the packaging efficiency is improved, but the adaptability to different vehicle styles deteriorates
Solution Approach 1:
The lighting device incorporates adjustable and configurable elements: the light sources can be switched between different colors (e.g., amber and white LEDs), the transparent lens can be configured with different patterns, and the housing design allows for flexible mounting orientations. This dynamic configurability enables the same integrated package to adapt to different vehicle styles and lighting requirements without requiring multiple separate devices.
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 enhances the aesthetic appeal and styling of vehicles by providing a multi-functional lighting system with direct and indirect light emissions, improving the packaging and adaptability of rear-view devices while maintaining functional lighting capabilities.
Implementation Method 1
at least one reflective element, wherein the at least one reflective element is arranged to reflect at least a part of the light beams from one of the at least two light sources
Implementation Method 2
at least two lightguides, wherein the at least two lightguides comprises a first lightguide and a second lightguide; light emitted from the light source is received by the light receiving surface of the lightguide and directed towards the light emitting surface of the lightguide
