Solution Overview
Problem
There is a need for a load control system that can be easily configured to operate appropriately in response to both wireless occupancy sensors and daylight sensors, which is not effectively addressed by existing technologies.
Innovation Solution
A load control device with a wireless communication circuit and controller that receives messages from occupancy sensors, daylight sensors, and remote controls, allowing it to automatically adjust its operation based on the presence or absence of these sensors, thereby controlling the lighting load effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a load control device is designed to work with multiple types of wireless sensors (occupancy sensors and daylight sensors), then the adaptability and versatility of the device is improved, but the device complexity increases due to the need for different configuration modes and sensor type detection mechanisms
Solution Approach 1:
The load control device automatically detects the type of wireless sensor present (occupancy sensor or daylight sensor) and self-configures the appropriate operational mode without requiring manual intervention. The device monitors incoming wireless messages and autonomously determines whether to operate in occupancy-responsive mode or daylight-responsive mode based on the sensor type detected, thereby simplifying the user experience while maintaining multi-sensor compatibility
Solution Approach 2:
The operational mode of the load control device is made dynamic and adaptable rather than fixed. The device can transition between different operational modes (occupancy-based control, daylight-based control, or combination mode) depending on which sensors are detected and configured. This dynamic adaptability allows the same hardware to serve multiple functions without requiring complex manual reconfiguration
2Ease of operation
If the load control device automatically detects and configures for different sensor types, then the ease of operation is improved, but the reliability may be affected by potential errors in automatic sensor type detection and mode selection
Solution Approach 1:
The load control device implements a feedback mechanism where it monitors the characteristics of incoming wireless messages from sensors and uses this information to verify and adjust its operational mode. The device continuously receives feedback from the sensors about their presence and status, allowing it to confirm correct mode selection and make adjustments if detection errors occur, thereby maintaining both ease of operation and system reliability
Solution Approach 2:
The device performs preliminary detection and analysis of wireless sensor messages during the configuration phase to pre-determine the appropriate operational mode before full operation begins. By conducting this detection action in advance, the device can establish the correct mode proactively, reducing the risk of operational errors while maintaining automatic configuration benefits

AI summary
A load control system for controlling an electrical load may include a sensor, a remote control, and a load control device. The remote control may comprise a button and may be configured to wirelessly transmit a digital message in response to an actuation of the button. The load control device may be configured to control the electrical load, be responsive to the sensor, and/or be configured to be associated with the remote control. The load control device may be responsive to the digital message transmitted by the remote control if the remote control is associated with the load control device. The load control device may be configured to automatically operate in a first mode of operation if the remote control is not associated with the load control device, and automatically operate in a second mode of operation if the remote control is associated with the load control device.
