Adaptive Vehicle Cabin Light with Dynamic Illumination Tracking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle cabin lights with fixed light sources fail to provide optimal reading conditions as the vehicle seat is adjusted, leading to suboptimal illumination when the seat is not in its predetermined position.
Innovation Solution
An adaptive vehicle cabin light system that includes adjustable light sources or optics controlled by a unit responsive to the seat's position, ensuring optimal illumination for any seating configuration by aligning light sources with corresponding reading areas as the seat moves.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed light source is used to illuminate a defined reading area, then the structure is simple and cost-effective, but reading conditions deteriorate as the vehicle seat moves away from the predetermined position
Solution Approach 1:
The patent applies the dynamics principle by making the light source adjustable rather than fixed. The light source can change its position or orientation to track the movement of the vehicle seat, ensuring that the reading area remains properly illuminated regardless of seat position. This dynamic adjustment capability resolves the contradiction between maintaining good reading conditions and avoiding complex device structure.
Solution Approach 2:
The patent implements feedback by using a sensor to detect the position of the vehicle seat and automatically adjusting the light source position based on this information. The control unit processes the sensor data and actuates the light source to maintain optimal illumination on the reading area. This closed-loop feedback system ensures adaptability without requiring constant manual intervention.
2Adaptability or versatility
If multiple light sources are used to cover different seat positions, then reading conditions remain optimal across all positions, but device complexity and power consumption increase
Solution Approach 1:
Instead of having multiple light sources simultaneously active, the patent uses a single adjustable light source that dynamically repositions itself to illuminate different reading areas. This dynamic approach allows one light source to serve multiple positions sequentially, reducing power consumption compared to having multiple light sources operating at the same time while maintaining full illumination coverage.
Solution Approach 2:
The adjustable light source is designed to perform multiple functions by illuminating different reading areas corresponding to various seat positions. A single light source unit can serve the function of multiple fixed light sources would provide, making the system more energy-efficient while maintaining versatility across all seating positions.
3Adaptability or versatility
If the light source is adjusted to follow the seat position, then optimal reading conditions are maintained, but device complexity increases due to additional control mechanisms
Solution Approach 1:
The patent uses a feedback-based control system where a sensor detects seat position and automatically triggers light source adjustment. This automated feedback loop eliminates the need for complex manual adjustment mechanisms while maintaining optimal illumination tracking. The control unit processes sensor information and actuates the light source accordingly, providing adaptability with relatively simple control logic.
Solution Approach 2:
The system implements self-service by automatically detecting seat position changes and adjusting the light source without requiring user intervention. The sensor and control unit work together to autonomously maintain optimal reading conditions, reducing the complexity of manual adjustment mechanisms while achieving the desired adaptation.

AI summary
Embodiments of the present invention are directed to an adaptable vehicle cabin light, with which in all seating positions of a vehicle seat, reading conditions are optimal. The vehicle seat is adjustable. Each position of the vehicle seat has a corresponding reading area. The vehicle cabin light includes one or more light sources that align with the different reading areas. As the vehicle seat moves, the illumination moves with it. In some embodiments, the one or more light sources are controlled by a control unit which selectively turns on a group of the one or more light sources to illuminate the corresponding reading area of the position of the vehicle seat. In some embodiments, the one or more light sources are enclosed in an adjustable optics, wherein movements of the adjustable optics are controlled by the control unit.
