Integrated Vehicle Lamp Lens Layout for Slim Multi-Function Beams
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vehicle lamps struggle to achieve a slim and integrated appearance while maintaining distinct functional capabilities, leading to a sense of separation between multiple lamps.
Innovation Solution
The integration of lens units from multiple lamps, along with the arrangement of lamp modules in a left-right direction, forms an optimal beam pattern and a slim form factor, eliminating the perception of separation between lamps.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple separate lamps are used to satisfy functional requirements, then the functional capabilities are sufficient, but a sense of separation between lamps occurs and the form factor becomes bulky
Solution Approach 1:
The patent combines multiple separate lamps (headlamp and fog lamp, or daytime running lamp and position lamp) into a single integrated lamp assembly. The lamp housing and lens are unified structures that accommodate multiple light sources and optical units, eliminating the visual separation between lamps while maintaining distinct functional zones through internal arrangement and optical design.
Solution Approach 2:
The integrated lamp assembly performs multiple functions simultaneously - illumination (headlamp), fog lighting, daytime running, and position lighting - all within a single structural unit. The lamp housing serves as both the structural framework and the aesthetic exterior element, while the lens performs both protection and light distribution functions.
2Ease of manufacture
If lens units are separately formed for each lamp, then manufacturing is simpler, but an integrated appearance cannot be achieved
Solution Approach 1:
The patent forms a single integrated lens structure that covers multiple optical units within one piece. This unified lens maintains the aesthetic continuity and integrated appearance from the exterior, while internally providing distinct optical zones for different lamp functions through varied refraction patterns and surface geometries.
3Shape
If lamp modules are arranged in left-right direction, then an integrated appearance is achieved, but beam pattern optimization becomes more complex
Solution Approach 1:
The patent applies different optical characteristics to different regions of the integrated lens and optical units. Each optical unit has customized refractive surfaces, reflector geometries, and light source positions tailored to its specific function (illumination, signaling, fog lighting), allowing optimal beam patterns for each function while maintaining overall integration.

Implementation Method 1
a lens unit disposed in front of the first optical unit and the second optical unit to allow the light irradiated from at least one of the first optical unit or the second optical unit to pass through the lens unit
Implementation Method 2
a lens unit disposed in front of the first optical unit and the second optical unit to allow the light irradiated from at least one of the first optical unit or the second optical unit to pass through the lens unit to form at least one of the first beam pattern or the second beam pattern
