Resettable Lighting System With Non-Volatile Memory
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional reset mechanisms for connected lighting systems, especially those installed in difficult-to-reach locations like ceiling fixtures, require continuous power to detect reset triggers, making it impossible to reset the system when disconnected from power, thus necessitating a powerless reset solution.
Innovation Solution
A connected system with a physical reset switch and non-volatile reset memory that records and remembers the switch state even when the system is unpowered, allowing for a master reset upon power restoration and enabling reboot or configuration changes based on detected power patterns.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If continuous power is supplied to detect reset triggers, then reset detection reliability is improved, but energy consumption increases and the system cannot be reset when disconnected from power
Solution Approach 1:
The patent applies preliminary action by capturing and storing the reset switch state in non-volatile memory before power is lost. The system detects the reset trigger event while powered, records the state, and preserves it across power cycles. This allows the system to reliably detect reset triggers without requiring continuous power during the reset operation, resolving the contradiction between reset detection reliability and energy consumption.
2Ease of operation
If the reset switch state is stored in non-volatile memory, then the system can be reset when unpowered, but device complexity increases
Solution Approach 1:
The patent applies segmentation by separating the reset detection and state storage functions into distinct components: a reset switch for trigger detection, non-volatile memory for state preservation, and a controller for coordinating their operation. This modular segmentation enables the system to achieve reset capability when unpowered while managing device complexity through functional decomposition and clear separation of concerns.

AI summary
A lighting system, including: light emitting elements; a reset switch operable in a first and second state; non-volatile reset memory configured to record the state of the reset switch when power is provided to the system; a wireless communication system; non-volatile communication memory configured to store default settings and configuration settings; a control system operable, in response to initial power provision to the control system, between: a configured mode when an instantaneous reset switch state matches the recorded state, the configured mode including: connecting the wireless communication system to a remote device based on the configuration settings, receiving instructions from the remote device, and controlling light emitting element operation based on the instructions; and a reset mode when the instantaneous reset switch state differs from the recorded state, the reset mode including: erasing the configuration settings from the communication memory and operating the system based on the default settings.
