Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current load control systems require time-consuming and inconvenient association methods for control-source and control-target devices, which involve physically actuating buttons and identifying device locations, making it difficult to configure devices effectively.
Innovation Solution
A load control system that includes a system controller for monitoring operations and transmitting digital messages, allowing for area-by-area association of control-source devices with control-target devices using a network device with a visual display, and employing flashing profiles to identify devices during configuration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional button-actuating association methods are used, then control devices can be associated, but the process is time-consuming and inconvenient
Solution Approach 1:
The patent replaces mechanical button-actuating association methods with acoustic signal-based identification. Control devices emit and respond to audible sound waves (e.g., through speakers or LEDs that can be perceived), allowing users to identify and associate devices by listening to their acoustic signatures rather than physically interacting with buttons or manually locating devices. This substitution of mechanical interaction with acoustic field interaction streamlines the association process.
Solution Approach 2:
The control devices automatically emit identification signals and respond to association commands without requiring manual button pressing or complex user intervention. The devices self-identify through acoustic signals, and the association process occurs automatically once the user selects the desired device based on its acoustic signature, eliminating the need for time-consuming manual configuration steps.
2Adaptability or versatility
If device locations must be identified manually, then association can be established, but the process becomes complex and difficult
Solution Approach 1:
The patent replaces manual location identification with acoustic signal propagation. Control devices emit sound waves that travel through the physical space, allowing users to locate devices by the direction and intensity of the acoustic signals rather than manually searching for or visually identifying device positions. This acoustic field-based approach simplifies the configuration process while maintaining spatial adaptability.
Solution Approach 2:
Acoustic signals serve as an intermediary between the control devices and the user during the association process. Instead of directly interacting with devices or their physical locations, users interact with the acoustic representations of the devices, which mediate the identification and association process. This intermediary layer simplifies user-device interaction while preserving the ability to configure devices in various locations.

AI summary
Control-source devices may be associated with control-target devices of a load control system during a configuration procedure, such that the control-target devices are responsive to the associated control-source devices during normal operation. The configuration procedure may be executed using a network device having a visual display for associating the control-source devices and control-target devices. The control-source devices may be associated with the control-target devices on an area-by-area basis using an area configuration procedure. The control-target devices may be configured to flash a controlled lighting load according to a flashing profile during the configuration procedure. The flashing profile may be characterized by at least one abrupt transition between off and on, and at least one gradual transition between off and on, where the abrupt and gradual transitions are repeated on a periodic basis.
