Motorcycle Headlamp Lens Layout for Compact Beam Packaging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing headlamp units for saddle riding vehicles have large outer lenses due to the integration of both high and low beam lights, which affects the size and aesthetic appearance.
Innovation Solution
The headlamp unit is designed with two low beam outer lenses arranged side by side and a single high beam outer lens positioned between them, disposed below and rearward of the low beam lenses, utilizing separate lenses for each beam type to reduce overall size.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If a single outer lens integrates both high beam and low beam light sources, then the headlamp unit can be compact, but the outer lens size becomes excessively large
Solution Approach 1:
The patent divides the headlamp into separate low beam outer lenses and high beam outer lenses. The low beam outer lenses are arranged side by side, while the high beam outer lens is positioned above or below them, creating distinct optical zones for different beam types and reducing the size of each individual lens.
Solution Approach 2:
The patent transitions from a two-dimensional planar arrangement to a three-dimensional spatial configuration by stacking high beam outer lenses above or below the low beam outer lenses in the vertical direction, while maintaining compact horizontal spacing. This dimensional reorganization reduces the overall footprint and individual lens sizes.
2Device complexity
If a single large outer lens is used for both high and low beams, then lens integration is simplified, but the aesthetic appearance deteriorates due to excessive size
Solution Approach 1:
The patent segments the headlamp optics into distinct low beam outer lenses and high beam outer lenses, allowing each lens to be optimized for its specific function and size, thereby improving aesthetic appearance while maintaining manageable integration complexity through modular design.
Solution Approach 2:
The patent combines multiple smaller outer lenses (low beam outer lenses and high beam outer lens) into a unified headlamp assembly with coordinated arrangement, achieving both aesthetic compactness and functional integration without requiring a single oversized lens.
3Area of stationary object
If separate outer lenses are used for high beam and low beam, then individual lens size is reduced, but the overall headlamp unit configuration becomes more complex
Solution Approach 1:
The patent resolves configuration complexity by stacking high beam outer lenses in the vertical dimension above or below the low beam outer lenses, rather than expanding horizontally. This spatial arrangement maintains compact overall dimensions while accommodating separate lenses for different beam types.
Solution Approach 2:
The patent segments the headlamp into functionally distinct low beam outer lenses and high beam outer lens groups, with clear spatial separation in the vertical direction, making the configuration manageable and maintainable while achieving reduced individual lens sizes.
