Persistent Luminescent Vehicle Accessory Illumination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vehicle lighting systems lack efficient energy management and adaptive illumination capabilities to enhance user experience and safety by selectively illuminating vehicle accessories based on detected conditions or scheduled tasks, while minimizing power consumption.
Innovation Solution
A lighting apparatus with a persistent luminescent portion that charges in response to an excitation emission from a light source, controlled by a detection sensor and controller to activate the light source only when needed, ensuring energy-efficient illumination of vehicle accessories, such as charging ports or communication interfaces, and adjusting intensity based on user interaction or ambient light levels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If the light source is continuously activated to provide illumination for vehicle accessories, then the illumination intensity and user experience are improved, but the power consumption increases
Solution Approach 1:
The light source operates periodically rather than continuously - it is activated only when a mobile device is detected near the vehicle and deactivated when the device moves away. This periodic operation provides illumination only when needed, resolving the contradiction between maintaining illumination intensity and reducing power consumption during idle states
Solution Approach 2:
The system uses the mobile device's own presence (detected via radio transceiver) to trigger the lighting operation, making the lighting service automatic and context-aware. The lighting activates itself when a user approaches and deactivates when the user leaves, eliminating the need for manual control while optimizing energy usage
2Use of energy by moving object
If the light source is activated only when a mobile device is detected, then the power consumption is reduced, but the response time and user experience may be delayed
Solution Approach 1:
The radio transceiver continuously monitors for the presence of mobile devices in advance, so when a user approaches the vehicle, the system is already aware and can immediately activate the light source without delay. This preliminary detection eliminates response time lag while maintaining energy efficiency by only activating when actually needed
3Reliability
If traditional lighting systems are used without selective activation, then the illumination is always available, but the energy management efficiency is poor
Solution Approach 1:
The system uses feedback from the radio transceiver that detects mobile device presence to control the lighting operation. This feedback mechanism ensures illumination is available reliably when users need it (when devices are detected) while automatically reducing power consumption during idle periods, thereby improving energy management efficiency without sacrificing illumination reliability
