Wireless Control Pairing by Relative Movement and Signal Strength
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing high-efficiency lamps with wireless receivers face challenges in associating with remote control devices due to limited space for button actuation and installation locations that are not easily accessible to users.
Innovation Solution
A load control system enables wireless control devices to associate and disassociate based on movements relative to each other, using received signal strength to determine the association or disassociation, allowing for button-free association and disassociation procedures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If button actuation is used for association, then reliable device pairing is achieved, but ease of operation deteriorates due to limited space and inaccessibility
Solution Approach 1:
The patent replaces the mechanical button-pressing system with a wireless signal-based system. The control device transmits wireless signals that are detected by the lamp, eliminating the need for physical button actuation. This substitution resolves the contradiction by maintaining reliable association (through signal detection and unique identifier verification) while dramatically improving ease of operation (no physical access needed to the lamp).
Solution Approach 2:
The patent introduces wireless signals as an intermediary between the user and the lamp's association function. Instead of direct mechanical interaction, the user operates a remote control device that sends wireless commands, and the lamp's control circuit receives and processes these signals. This intermediary mechanism allows association to occur without physical contact, resolving the accessibility problem while maintaining system reliability through proper signal authentication.
2Adaptability or versatility
If wireless receivers are integrated into lamps, then control functionality is improved, but device complexity increases due to additional components
Solution Approach 1:
The patent merges the wireless receiver functionality directly into the lamp's existing control circuitry. The control circuit is designed to integrate both the wireless signal reception capabilities and the load control functions in a unified structure. This merging approach adds wireless adaptability to the lamp while minimizing the increase in device complexity by sharing common components and integration architecture.
Solution Approach 2:
The control circuit in the lamp is designed with multi-functionality, serving both traditional wired control purposes and wireless control purposes. The same control circuit processes signals from both types of control mechanisms, eliminating the need for separate dedicated wireless control hardware. This universality approach enhances adaptability while controlling device complexity through component sharing.

AI summary
A first wireless control device may be associated with a second wireless control device in response to the movement of the first wireless control device in relation to the second wireless control device. The second control device may determine whether the signal strength of the wireless signals received from the first wireless control device has changed, and may associate the first wireless control device with the second wireless control device if the signal strength of the received wireless signals has changed. The second control device may be disassociated with the first control device by moving the first wireless control device in relation to the second wireless control device. The second control device may disassociate the first control device when the signal strength of subsequent wireless signals received from the first wireless control device has changed.
