Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current manufacturing methods for automobile head lamps are inefficient in terms of cost and time due to the separate production of high and low beams, resulting in increased size and complexity.
Innovation Solution
A single module design for automobile head lamps incorporating a first and second light source, light guide units, and a lens unit that allows for the integration of high and low beam functions, reducing size and manufacturing costs, with independent control of second light sources for glare prevention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If high beam and low beam are configured as separate modules, then each beam can be independently optimized, but manufacturing costs and time increase and overall size increases
Solution Approach 1:
The patent combines high beam and low beam modules into a single integrated headlamp assembly. The housing contains both light sources (first light source for high beam, second light source for low beam) within one structure, with a single lens unit that has different refractive index regions for controlling each beam type. This merging eliminates separate manufacturing processes and reduces overall assembly complexity.
Solution Approach 2:
The lens unit is designed with multi-functionality to handle both high beam and low beam light paths. It includes a first lens portion with a first refractive index for high beam light and a second lens portion with a second refractive index for low beam light, allowing a single component to perform multiple optical functions that would traditionally require separate modules.
2Manufacturing precision
If high beam and low beam are configured as separate modules, then each beam can be independently optimized, but the overall size of the head lamp increases
Solution Approach 1:
The patent implements a nested arrangement where the first light source and second light source are positioned within the same housing space. The light guide units and lens portions are arranged concentrically and adjacently, with the first light guide unit for high beam and the second light guide unit for low beam sharing the same optical axis and housing volume, effectively nesting multiple functional elements within a compact structure.
Solution Approach 2:
The patent utilizes vertical dimensionality arrangement by positioning the first light source above the second light source along the vertical axis. The lens unit is divided into upper and lower regions corresponding to each light source, with the upper region handling high beam and the lower region handling low beam. This vertical stacking in the Z-dimension allows compact integration without increasing horizontal footprint.
3Productivity
If a single module is used for high and low beam, then manufacturing costs and time are reduced, but light interference and glare control become more complex
Solution Approach 1:
The lens unit is designed with spatially varying optical properties, where different regions have different refractive indices tailored to their specific functions. The first lens portion has a first refractive index optimized for high beam light control, while the second lens portion has a second refractive index optimized for low beam light control. This local quality differentiation allows each region to independently control its respective beam without interfering with the other, simplifying the overall optical design within the integrated module.
Solution Approach 2:
The patent segments the lens unit into distinct functional regions: a first lens portion for high beam control and a second lens portion for low beam control. The housing is also segmented with separate light guide units for each beam type. This segmentation allows independent optimization of each beam path while maintaining physical integration, reducing optical interference and simplifying control mechanisms.
4Volume of moving object
If first light guide unit and second light guide unit are positioned closely, then lamp size is reduced, but light from one source may interfere with the other beam
Solution Approach 1:
The patent introduces a shield unit positioned between the first light guide unit and the second light guide unit. This shield acts as an optical intermediary that blocks stray light from the high beam source from entering the low beam optical path and prevents low beam light from interfering with the high beam path. The shield is integrated into the housing structure and strategically positioned to eliminate cross-contamination between the two beam systems while maintaining compact overall dimensions.
