Vehicle Light Module Compact Planar Reflector Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing light-emitting modules for vehicles require high positioning accuracy and have a large height due to the structural size of concave reflectors, making them less compact.
Innovation Solution
A light-emitting module with a compact design, where the first and second light sources and their corresponding reflectors are arranged on the same mounting surface of a carrier, and a lens projects light to form distributions associated with the reflectors' surfaces, reducing overall height and improving manufacturing tolerance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If two concave reflectors are arranged on top of each other, then different light functions can be achieved, but the overall height increases due to structural size requirements
Solution Approach 1:
The patent transitions from a vertical stacking arrangement (height direction) to a planar arrangement on the same mounting surface (lateral direction). Multiple reflectors and light sources are distributed on a two-dimensional mounting surface rather than stacked in three dimensions, effectively reducing the height dimension while maintaining functional versatility.
Solution Approach 2:
The patent combines multiple light sources and reflectors on a single mounting surface of one carrier, integrating what would traditionally require separate mounting structures. This merging approach consolidates the optical components into a compact configuration that achieves multiple light functions without increasing overall height.
2Manufacturing precision
If concave reflectors with specific focal points are used, then light distribution can be controlled, but high positioning accuracy is required between components
Solution Approach 1:
The patent divides the optical system into modular units where each light source has its dedicated reflector and positioning structure on the mounting surface. This segmentation allows for independent positioning and adjustment of each component, reducing the cumulative positioning errors that would occur in integrated systems and lowering the overall positioning accuracy requirements.
Solution Approach 2:
The mounting surface acts as an intermediary structure that provides standardized positioning features and mounting interfaces. This intermediary element decouples the positioning requirements between light sources and reflectors, allowing each to be positioned independently with reference to the mounting surface rather than requiring precise relative positioning between each other.
3Length of stationary object
If a compact design is implemented, then overall height is reduced, but positioning tolerance requirements become more stringent
Solution Approach 1:
The mounting surface is designed as a universal platform that accommodates multiple light sources and reflectors with standardized mounting interfaces. This universal design allows for flexible arrangement of components within the compact form factor while maintaining consistent positioning tolerances through standardized features, reducing the impact of compact design on positioning tolerance requirements.
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 module achieves a compact size by reducing the overall height, allowing for multiple light functions to be performed in a smaller vertical space, while being insensitive to positioning tolerance of light sources relative to reflectors.
Implementation Method 1
a first reflector, assigned to the first light source, for receiving and reflecting light emitted from the first light source along the main light exit direction
Implementation Method 2
a lens, which projects light emitted from the first light source and the second light source, wherein the lens is configured to correspondingly form light distributions associated with reflecting surfaces of the first reflector and the second reflector
