Seat Switch Lighting Control for Folded Armrest Glare
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lighting control systems for vehicle seat switches do not effectively manage glare and visual aesthetics, particularly when the armrest is folded, and lack sophisticated control over lighting intensity and fade functions.
Innovation Solution
A lighting control system that uses a position recognizer, such as a G-sensor, to detect the armrest's position and control the lighting intensity through a controller, implementing fade-in and fade-out functions to adjust brightness based on the armrest's position, preventing glare when folded and enhancing visual aesthetics by gradually increasing or decreasing light intensity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If the seat switch lighting is always on to improve visibility and appearance, then visibility and aesthetics are improved, but glare occurs when the armrest is folded
Solution Approach 1:
The lighting control system dynamically adjusts the lighting state based on armrest position. When the armrest is detected to be folded, the system automatically turns off or dims the seat switch lighting to prevent glare. When the armrest is in normal position, the lighting is activated for visibility and aesthetics. This dynamic adaptation resolves the contradiction between maintaining visibility and preventing glare.
Solution Approach 2:
The system uses a position recognizer (such as a sensor) to detect the armrest position and provides feedback to the lighting control unit. Based on this feedback, the lighting control unit adjusts the lighting state accordingly. This closed-loop feedback mechanism ensures that lighting is only active when appropriate, preventing glare while maintaining visibility when needed.
2Device complexity
If simple on/off lighting control is used to reduce system complexity, then device complexity is reduced, but visual aesthetics and user experience are compromised
Solution Approach 1:
The lighting control system provides dynamic intensity adjustment through fade-in and fade-out functions. Instead of simple on/off control, the system gradually increases or decreases lighting intensity based on armrest position changes. This adds sophistication to lighting control while maintaining reasonable system complexity through the use of standard control algorithms.
3Adaptability or versatility
If lighting is activated whenever armrest moves to improve functionality, then functionality is improved, but energy consumption increases
Solution Approach 1:
The system uses fade-in and fade-out functions to gradually transition lighting states rather than abrupt on/off switching. This preliminary action of gradual transition improves the user experience by reducing visual shock while actually reducing energy consumption compared to frequent abrupt activations. The fade functions are triggered only by significant armrest position changes, not minor movements.

AI summary
Disclosed is a lighting control system of a vehicle seat switch (10). The lighting control system includes a movable object (4) mounted to be rotatable with respect to a stationary object (2), a switch (10) mounted on the movable object and configured to emit light, a position recognizer (20) installed in the switch to sense position information of the movable object (4), and a controller (30) configured to receive the position information and to adjust an intensity of light emitted by the switch based on the position information.
