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 - specifically, one optical system that can form both main beam patterns and sub-beam patterns. The light path adjustment portion and optical portion are configured to handle light from both main light sources and sub-light sources, enabling the same optical components to serve multiple beam pattern formation purposes, thereby reducing the need for separate optical systems.
Solution Approach 2:
The patent merges previously separate optical systems into a unified structure. The light path adjustment portion and optical portion are shared between main and sub-light sources, combining multiple functions into a single integrated system. This merging reduces component count while maintaining the capability to form different beam patterns through coordinated operation of the combined components.
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:
By designing the optical system with universal components that can handle both main and sub-light sources, the patent reduces manufacturing costs. The same light path adjustment portion and optical portion are used for multiple beam patterns, eliminating the need to manufacture separate optical systems for each beam type, thereby reducing overall production costs while maintaining versatility.
3Adaptability or versatility
If multiple light sources and optical components are used to form different beam patterns, then the beam pattern variety is improved, but the device complexity increases
Solution Approach 1:
The patent applies segmentation by dividing the light sources into main light sources and sub-light sources, with corresponding segmented optical paths. The light path adjustment portion is configured with distinct regions for handling main and sub-light, and the optical portion includes corresponding segments. This segmentation allows different beam patterns to be formed through coordinated operation of segmented components rather than requiring completely separate systems.
Solution Approach 2:
The optical components are designed with multi-functionality to handle both main and sub-light paths. The light path adjustment portion and optical portion can process light from either source type, reducing structural complexity by using the same physical components for multiple purposes rather than requiring dedicated components for each beam pattern type.

Implementation Method 1
an optical portion that transmits at least a portion of the light incident from the light path adjustment portion to allow at least one beam pattern to be formed
Implementation Method 2
an incident lens portion, which includes a first light-transmitting portion and a plurality of incident lenses disposed on an incident surface of the first light-transmitting portion; and an emitting lens portion, which includes a second light-transmitting portion having an incident surface thereof facing an emitting surface of the first light-transmitting portion and a plurality of emission lenses disposed on an emitting surface of the second light-transmitting portion
Implementation Method 3
a reflector that reflects at least a portion of the light emitted from the at least one sub-light source to cause it to proceed toward the optical portion
Implementation Method 4
at least one guide lens that guides the 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 include a diffusion pattern formed on at least one of an incident surface or an emitting surface thereof for diffusing light
