Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If multiple lamp modules are disposed in vehicle width direction to achieve slim design, then the form factor is reduced, but the number of parts increases and configuration becomes complex
Solution Approach 1:
The patent merges multiple lamp modules into a single integrated lamp module structure. Specifically, multiple lenses are arranged in the vehicle width direction within one module, and a single light guide unit with multiple emission surfaces serves all lenses, eliminating the need for separate light guide units for each lens and reducing overall configuration complexity
Solution Approach 2:
The light guide unit is designed with multi-functionality to serve multiple lenses simultaneously. A single light guide unit incorporates multiple emission surfaces that respectively correspond to multiple lenses, allowing one component to perform the function of what would traditionally require multiple separate components, thus simplifying the overall configuration
2Length of moving object
If multiple lamp modules are disposed in vehicle width direction to achieve slim design, then the form factor is reduced, but the number of parts increases
Solution Approach 1:
The patent combines multiple lamp modules into one integrated module by merging the light guide units. Instead of having separate light guide units for each lens, a single light guide unit with multiple emission surfaces is used, directly reducing the number of parts while maintaining the slim form factor achieved by arranging multiple lenses in the vehicle width direction
3Reliability
If traditional lamp configuration is used, then beam pattern formation is effective, but the form factor is large and slim design cannot be achieved
Solution Approach 1:
The patent transitions from a traditional vertical stacking arrangement to a horizontal arrangement in the vehicle width direction. By disposing multiple lenses side-by-side in the width direction rather than stacking them vertically, the design achieves a slim form factor while maintaining effective beam pattern formation through the coordinated arrangement of multiple emission surfaces and lenses

Function Achieved in This Case
This configuration enables a slimmer form factor for vehicle lamps while reducing the number of parts and simplifying the configuration, allowing for efficient beam pattern formation and cost reduction.
Implementation Method 1
a light guide unit that guides the light incident on an incidence portion from the light source unit to be emitted to an emission portion
Implementation Method 2
a reflection portion including at least one reflection surface configured to reflect the light incident on the incidence portion to the transmission portion
Implementation Method 3
an optical unit that transmits the light emitted from the light guide unit to allow a predetermined beam pattern to be formed. In particular, the optical unit may include a plurality of lenses disposed in a vehicle width direction
