Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current lighting devices require an accurate clock for resetting, making the process cumbersome and user-unfriendly, especially when errors occur or during initial deployment.
Innovation Solution
A lighting apparatus with a control circuit, reset sensor, and reset circuit that detects status variations, such as temperature, magnetic field, or light pattern changes, to generate a reset signal and automatically reset the system, allowing for manual switch operation and self-testing procedures without relying on an external clock.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an accurate clock is used for resetting the lighting device, then the reset function can be implemented, but the device complexity increases and ease of operation deteriorates
Solution Approach 1:
The patent removes the clock component from the resetting mechanism. Instead of using a time-based reset system that requires an accurate clock, the invention uses a status variation detection system that triggers resets based on environmental changes or user actions, completely extracting the time-dependent element from the reset function
Solution Approach 2:
The lighting device automatically detects status variations through sensors and self-resets without requiring external time synchronization or clock management. The system serves itself by monitoring environmental parameters and autonomously initiating reset operations when predetermined conditions are met
2Reliability
If an accurate clock is required for resetting, then time-based control can be achieved, but ease of operation deteriorates due to the cumbersome process
Solution Approach 1:
The patent replaces the mechanical/time-based reset system with a sensor-based detection system. Instead of relying on clock signals and time-based triggers, the invention uses sensors to detect status variations in the environment or device state, substituting temporal control with physical parameter detection
Solution Approach 2:
The patent introduces sensors as intermediaries between the environment and the control circuit. These sensors detect status variations and translate them into signals that trigger the reset function, serving as a mediator that eliminates the need for direct time-based control while maintaining reliable reset functionality

Data Source
AI summary
A lighting apparatus includes a control circuit, a light source, a reset sensor and a reset circuit. The control circuit operates according to a default setting when the control circuit is started. The light source is controlled by the control circuit. The reset sensor detects a status variation. The status variation is caused by an external device outside the lighting apparatus. The reset circuit is coupled to the reset sensor for generating a reset signal to the control circuit to reset the control circuit when the status variation satisfies a predetermined triggering condition.
