Lighting Controller High Sensitivity Mode Sensor Testing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users of networked lighting systems face challenges in verifying the correct configuration and operation of added sensors, as existing systems lack intuitive feedback, leaving users uncertain about the setup and functionality of new sensors.
Innovation Solution
A lighting system controller that temporarily switches to a high sensitivity mode when a new sensor is added, increasing communication frequency and sensitivity to assist users in testing the sensor's functionality, allowing easier triggering and confirmation of sensor responses, and providing feedback through lighting changes or user interface notifications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the system operates in normal operational mode with standard communication frequency, then energy consumption is reduced and system stability is maintained, but users cannot easily test sensor functionality and receive feedback
Solution Approach 1:
The system dynamically adjusts communication frequency based on operational context. During sensor addition, the controller switches to high sensitivity mode with increased polling frequency. After sensor addition completes, the system returns to normal operational mode with standard communication frequency, thus balancing testing capability with energy efficiency.
Solution Approach 2:
The controller proactively enters high sensitivity mode automatically upon detecting sensor addition, preparing the system for immediate sensor testing before the user even attempts to test the sensor. This preliminary action ensures the system is ready for interaction without requiring manual configuration changes.
2Loss of information
If the system increases communication frequency to high sensitivity mode, then sensor testing capability is improved and user feedback is enhanced, but energy consumption increases
Solution Approach 1:
The system implements periodic switching between normal operational mode and high sensitivity mode based on operational context. High sensitivity mode with increased communication frequency is activated only during sensor addition and testing phases, then deactivated when returning to normal operation, providing feedback only when necessary.
Solution Approach 2:
The increased communication frequency during high sensitivity mode enables the controller to receive sensor data more frequently, providing timely feedback to users about sensor functionality through lighting changes or notifications. This enhanced feedback loop is temporary and only active when sensor verification is needed.
3Ease of operation
If the system uses standard polling frequency, then system stability is maintained, but sensor functionality cannot be easily verified by users
Solution Approach 1:
The polling frequency is made dynamic rather than static. The controller automatically adjusts polling frequency based on system state: high frequency during sensor addition for easy verification, and standard frequency during normal operation for stability. This dynamic adaptation resolves the contradiction between verification ease and system stability.
4Measurement precision
If the system switches to high sensitivity mode with increased polling frequency, then sensor response detection is improved, but system complexity increases
Solution Approach 1:
The controller automatically detects when a sensor has been added and autonomously switches to high sensitivity mode without requiring user intervention or complex external control logic. The system self-manages the transition between operational modes, simplifying the overall control architecture despite the dynamic behavior.

AI summary
A lighting system controller for a lighting system having lighting units and sensors which together form a communications network. A new sensor may be added to the network as a new network node. In response to this, a high sensitivity mode is implemented, for assisting the user in testing the new sensor function.
