Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing rear vehicle lamps require separate functional and design components, leading to a complex structure and increased manufacturing costs.
Innovation Solution
An integrated inner lens for vehicle lamps that combines functional and design components, using a light transmission part, a light distribution formation part, and an image formation part to create a light distribution pattern and an image pattern simultaneously.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If separate functional components and design components are provided, then the required functions and designs can be implemented, but the lamp structure becomes complicated and manufacturing cost increases
Solution Approach 1:
The patent merges the light guide portion and the reflector into a single integrated inner lens component. The inner lens includes a light guide portion that guides light from the light source and a reflector that reflects light, both functions combined in one piece. This integration reduces the number of separate components while maintaining the required light distribution and design functions, thereby simplifying the overall lamp structure and reducing manufacturing complexity
Solution Approach 2:
The inner lens is designed as a multi-functional component that simultaneously performs light guiding, light reflection, and aesthetic design functions. The light guide portion guides light from the light source along its outer surface, while the reflector reflects light to enhance illumination. The integrated structure also serves as a design element that enhances the aesthetic appearance of the rear lamp, making one component perform multiple functions that previously required separate parts
2Adaptability or versatility
If separate functional components and design components are provided, then the required functions and designs can be implemented, but manufacturing cost increases
Solution Approach 1:
The patent combines multiple functional components (light guide and reflector) into a single molded inner lens, reducing the number of manufacturing steps, assembly operations, and inventory items. This integration simplifies the manufacturing process and reduces overall production cost while maintaining all required functions
Solution Approach 2:
The inner lens is designed as a multi-functional component that simultaneously performs light guiding, light reflection, and aesthetic design functions. By making one component perform multiple functions that previously required separate parts, the patent reduces the total number of parts to be manufactured, assembled, and managed, thereby reducing manufacturing cost

AI summary
Disclosed is an inner lens provided in a lamp, the inner lens including a light transmission part through which at least a portion of a light beam output from a light source passes and is then output, a light distribution formation part that outputs, to an outside of the lamp, a light beam, which forms a light distribution pattern, within a transmission light beam that is the light beam output from the light transmission part, and an image formation part that outputs, to the outside, a light beam, which forms an image pattern, among the transmission light beam.
