Hidden Vehicle Lighting Lens With Rotating Multi-Function Light Source
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicle headlights are fixed and visible, requiring additional lighting means for communication signals and welcome/goodbye motions, which is inefficient and unsightly.
Innovation Solution
A lighting device with a hidden light source unit embedded in a lens unit, featuring a first lens unit for light transmission and a second lens unit for concealment, along with a light rotation mechanism and detection units for environmental awareness, providing customizable lighting and auditory signals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the light source is fixed and visible, then the lighting function is simple and reliable, but additional lighting means must be added for communication signals and welcome/goodbye motions
Solution Approach 1:
The patent combines the communication lighting signal function and welcome/goodbye motion lighting function with the basic illumination function into a single integrated lighting device. The light source unit can perform multiple functions by changing its position and illumination direction, eliminating the need for separate lighting means.
Solution Approach 2:
The light source unit is designed to be movable rather than fixed, allowing it to change its position and illumination direction dynamically. This enables the same hardware to serve multiple purposes: basic illumination when facing forward, communication signals when positioned laterally, and welcome/goodbye motions through sequential activation patterns.
2Shape
If the light source is fixed and visible, then the structure is simple, but the aesthetic appearance is compromised due to visible internal components
Solution Approach 1:
The patent implements a nested lens structure where a second lens unit is disposed inside the first lens unit. The second lens unit can cover the first lens unit to hide the light source unit and internal components, providing an aesthetically pleasing appearance. When needed, the second lens unit can be retracted to allow light transmission.
Solution Approach 2:
The lens unit employs different optical properties in different regions: the first lens unit is designed for light transmission with specific optical characteristics, while the second lens unit is designed for concealment with opaque or diffusing properties. This local differentiation allows the same component to serve both aesthetic and functional purposes.
3Adaptability or versatility
If the light source unit rotates to change illumination direction, then multiple lighting functions are achieved, but the mechanism complexity increases
Solution Approach 1:
The lighting device is segmented into functionally independent light source units that can be independently controlled and positioned. Each light source unit can rotate or be positioned independently to achieve different illumination directions, allowing for simplified control mechanisms compared to a single complex movable assembly.

Function Achieved in This Case
Enhances vehicle visibility and communication through hidden lighting, ensuring aesthetic integration and adaptive functionality for various driving scenarios.
Implementation Method 1
a light source unit embedded in the lens unit and hidden in the lens unit or configured to radiate light to the lens unit
Implementation Method 2
a first lens unit exposed to the outside and configured to transmit the light that is radiated by the light source unit
Implementation Method 3
a second lens unit disposed inside the first lens unit and configured to cover the first lens unit so that the inside of the first lens unit is invisible to the naked eye
