Gesture-Based Interior Lighting Aiming to Replace Ceiling Switches
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle lighting systems require drivers or passengers to stretch and operate ceiling-mounted switches to adjust light positions, which is inconvenient and may lead to malfunctions.
Innovation Solution
A vehicle lighting device with a touch panel detector that allows users to control light positions and angles using intuitive finger motions, such as pinching, swiping, or scrolling, eliminating the need for ceiling-mounted switches and reducing the risk of malfunctions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a ceiling-mounted switch is used to control interior light, then the light can be turned on and off, but the driver or passenger must stretch their hand to the ceiling which reduces convenience
Solution Approach 1:
A camera is introduced as an intermediary device to capture images of the vehicle interior. The captured images are processed to identify objects of interest, and this information mediates between the user's intent and the lighting control system, enabling automatic or semi-automatic light positioning without manual ceiling switch operation
Solution Approach 2:
The manual mechanical switch operation on the ceiling is replaced with an automated vision-based system. The camera captures visual information, the processor analyzes the images to determine object positions, and the system automatically adjusts lighting accordingly, substituting the mechanical switching action with an automated optical-electronic control mechanism
2Reliability
If manual switch operation is required to adjust light position, then precise control can be achieved, but the risk of malfunction increases and convenience decreases
Solution Approach 1:
The system performs self-service by automatically detecting objects in the vehicle interior using camera images, identifying their positions and characteristics, and autonomously determining optimal lighting parameters. This eliminates the need for manual intervention, reducing operational complexity and potential for user error while maintaining system reliability through automated decision-making algorithms
3Illumination intensity
If the light irradiates a wide area to ensure coverage, then visibility is improved, but energy consumption increases
Solution Approach 1:
Instead of uniformly illuminating the entire vehicle interior, the system applies local quality by concentrating light precisely on detected objects of interest. The camera identifies specific targets such as passengers or cargo, and the lighting system adjusts to illuminate only those specific areas, providing adequate coverage where needed while reducing energy consumption in unoccupied regions

AI summary
Disclosed is a vehicle lighting device intended to improve convenience and safety. A vehicle lighting device includes a light disposed in a vehicle interior, a controller controlling the light, and a detecting unit detecting position or motion of a detecting object by detecting a detection object at a plurality of positions, and the controller controls the light when the position or motion of the detection object is detected by the detecting unit.
