Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle lamps require separate optical systems for forming different beam patterns, leading to increased component count and cost.
Innovation Solution
A vehicle lamp design that shares components of an optical system by using a light source portion with a main and at least one sub-light source, a light path adjustment portion, and an optical portion with incident and emitting lenses, allowing formation of multiple beam patterns.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If separate optical systems are provided to form two or more different beam patterns, then the beam pattern formation capability is improved, but the number of components increases and cost increases
Solution Approach 1:
The patent applies universality by designing a single optical system that can perform multiple functions - forming different beam patterns (main beam, sub-beam, daytime running light patterns) using the same optical components. The optical portion including incident lenses and emitting lenses serves multiple beam pattern formation purposes, eliminating the need for separate optical systems for each function.
Solution Approach 2:
The patent merges multiple beam pattern formation functions into a single integrated optical system. The light source portion with main and sub-light sources, combined with the optical portion containing incident and emitting lenses, creates a unified structure that generates various beam patterns simultaneously or selectively, reducing component count while maintaining versatility.
2Adaptability or versatility
If separate optical systems are provided to form two or more different beam patterns, then the beam pattern formation capability is improved, but the cost increases
Solution Approach 1:
The patent reduces manufacturing cost by creating a universal optical system that handles multiple beam pattern requirements. Instead of producing separate optical assemblies for main beams, sub-beams, and daytime running lights, the invention uses a single optical portion that can be manufactured once and serves all functions, thereby lowering production costs and simplifying manufacturing processes.
Solution Approach 2:
By combining multiple beam pattern formation functions into one optical system, the patent reduces the total number of components that need to be manufactured, assembled, and quality-tested. This merging approach directly lowers manufacturing costs through economies of scale and reduced assembly complexity.

Implementation Method 1
an optical portion configured to transmit at least a portion of light incident from the light path adjustment portion such that at least one beam pattern is formed
Implementation Method 2
an incident lens portion including a plurality of incident lenses and a first light-transmitting portion having the plurality of incident lenses positioned on an incident surface thereof; and an emitting lens portion including a plurality of emission lenses corresponding to the plurality of incident lenses
Implementation Method 3
a reflector configured to reflect at least a portion of light emitted from the at least one sub-light source to proceed toward the optical portion
Implementation Method 4
at least one guide lens configured to guide light emitted from the at least one sub-light source to be incident on the light path adjustment portion. The at least one guide lens may have a diffusion pattern formed on at least one of the incident surface and the emitting surface thereof, for diffusing light
