Lighting Device Pairing via Repeated Radio Commands
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lighting systems require complex procedures and additional components to pair lighting devices with radio remote controllers, leading to increased costs and unclear device states during pairing.
Innovation Solution
A pairing method that involves transmitting a pairing command repeatedly by the radio remote controller, determining the lighting device's initial state, and storing identification information when received, allowing the device to operate according to a radio command, with optional manual configuration modes using infrared remote controllers for added control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If receiver sensitivity is lowered to prevent false pairing, then pairing reliability is improved, but device complexity and cost increase due to receiver sensitivity adjuster
Solution Approach 1:
The patent changes the parameter of receiver sensitivity from adjustable to fixed at a high level, and instead uses temporal parameter (pairing mode duration) and procedural parameters (command repetition) to achieve reliable pairing without false pairings, eliminating the need for sensitivity adjuster
Solution Approach 2:
The patent extracts the sensitivity adjustment function from the hardware and replaces it with software-based pairing mode control, removing the receiver sensitivity adjuster component and simplifying the device structure
2Reliability
If receiver sensitivity is lowered to prevent false pairing, then pairing reliability is improved, but pairing procedure complexity increases
Solution Approach 1:
The patent implements preliminary action by automatically entering pairing mode when the lighting device is powered on, eliminating the need for manual sensitivity adjustment and preparing the device for automatic pairing without requiring user intervention in complex procedures
Solution Approach 2:
The lighting device performs self-service by automatically detecting its initial state, entering pairing mode, and waiting for pairing commands without requiring external control or complex user procedures, simplifying the pairing process
3Reliability
If lighting device is turned off during pairing, then false pairing from unspecified remote controllers is prevented, but device state clarity is worsened
Solution Approach 1:
The patent applies dynamics by making the lighting device state changeable - the device can be in different states (initial state, pairing mode, paired state) and transitions between them provide clear feedback on device status, eliminating the need to turn off the device during pairing
4Ease of operation
If pairing mode is activated automatically at power on, then ease of operation is improved, but device complexity increases due to initial state determination
Solution Approach 1:
The lighting device performs self-service by automatically detecting its initial state (whether identification information is stored) and entering pairing mode accordingly without requiring external control, simplifying the user interface while the internal state determination logic remains manageable

AI summary
A pairing method for causing lighting devices to store identification information of a radio remote controller serving as a master device is provided. The method includes: transmitting a pairing command including the identification information of the radio remote controller repeatedly on a temporary basis by the radio remote controller; determining, for each of the lighting devices, whether or not the lighting device is in an initial state in which identification information of a master device is not stored in the lighting device, at power on; storing the identification information included in the pairing command, if the paring command is received when it is determined that the lighting device is in the initial state in the determining; and causing the lighting device in which the identification information of the master device is stored to operate according to a radio command including the identification information of the master device.
