Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing home lighting control systems are complex and require expert installation, and smart light bulbs are limited by the associated light switch and fixture, leading to inconsistent dimming and difficulty in identifying bulb types and burnout detection.
Innovation Solution
A lighting control system that determines bulb type by comparing electrical energy and response correlations, allowing for synchronized dimming and burnout detection, and includes a controller to select dimming profiles and identify bulb manufacturer, wattage, and number based on measured electrical parameters.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If automated home lighting control systems with central hubs are installed, then lighting control functionality is improved, but system complexity and installation difficulty increase
Solution Approach 1:
The patent extracts the intelligence from centralized control hubs and places it directly into individual light bulb devices. Each smart bulb contains its own processor, memory, and communication capabilities, eliminating the need for complex external control systems while maintaining full lighting control functionality.
Solution Approach 2:
The smart bulbs perform self-identification, self-characterization, and self-configuration automatically. The bulbs detect their own type, measure their electrical characteristics, and register themselves with the control system without requiring manual setup or expert installation, thereby simplifying the overall system deployment.
2Extent of automation
If smart light bulbs are used with existing light switches, then lighting automation is improved, but bulb operability is limited by switch position
Solution Approach 1:
The patent implements dynamic state tracking where the system continuously monitors light switch positions and automatically adjusts bulb operation accordingly. The bulbs can be remotely controlled to override local switch limitations, and the system adapts its behavior based on the interaction between centralized commands and local switch states, ensuring reliable operation in all scenarios.
3Adaptability or versatility
If different bulb types are used in a lighting system, then lighting versatility is improved, but dimming coordination and scene synchronization become difficult
Solution Approach 1:
The patent implements a feedback mechanism where each bulb reports its type, characteristics, and operational state to the control system. The system uses this feedback information to calculate and distribute customized dimming profiles tailored to each bulb's specific characteristics, ensuring that all bulbs dim and brighten in a coordinated fashion across mixed bulb types while maintaining scene synchronization.
4Device complexity
If bulb type identification is not implemented, then system simplicity is maintained, but burnout detection and replacement efficiency are reduced
Solution Approach 1:
The patent performs preliminary bulb identification and characterization during the initial bulb registration phase. The system measures electrical parameters such as inrush current, steady-state current, and power consumption to determine bulb type, wattage, and manufacturer before the bulb is even used. This preliminary information is stored and used for future burnout detection and automated replacement ordering, eliminating the need for manual bulb identification later.
