Wireless Device Control Identifier Acquisition via Positional Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems face difficulties in specifying and controlling devices, such as lights, due to challenges in acquiring a control identifier and determining the transmitter of a WAKE-UP signal, leading to inefficient device control.
Innovation Solution
A wireless device equipped with searching, determining, and transmitting means that searches a database for positional information to acquire control identifiers for nearby devices, determines the controlled device and action, and transmits the control identifier via wireless communication to the receiver, enabling simple specification and control of devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If a WAKE-UP signal is used to transition from sleep mode to active mode, then power consumption is reduced, but it becomes difficult to specify the controlled device and acquire a control identifier
Solution Approach 1:
The patent segments the wireless signal into two distinct parts: a WAKE-UP signal for power saving and a control identifier signal for device specification. The transmitting device sends the WAKE-UP signal first to activate the receiving device, then separately transmits the control identifier that specifies which device should be controlled. This segmentation allows the system to maintain low power consumption while enabling precise device identification and control.
2Use of energy by moving object
If the router keeps only two circuits active in sleep mode, then power consumption is reduced, but the ability to detect and respond to control signals is limited
Solution Approach 1:
The patent applies preliminary action by having the transmitting device send a WAKE-UP signal before the control identifier signal. The WAKE-UP signal activates the receiving device's full wireless circuitry in advance, ensuring that when the control identifier signal arrives, the receiver is fully operational and ready to detect and process it reliably. This preliminary activation resolves the contradiction by ensuring reliable signal detection while maintaining power savings during the actual sleep state.
3Productivity
If positional information is used to acquire control identifiers, then device control becomes more efficient, but the complexity of the system increases
Solution Approach 1:
The patent introduces positional information as an intermediary element that bridges the transmitting device and the controlled device. Instead of requiring direct complex pairing or manual device selection, the system uses the transmitting device's positional data to automatically identify and acquire the appropriate control identifier for nearby devices. This intermediary approach simplifies the user interaction while maintaining system efficiency, as the positional information automatically resolves which device should be controlled without requiring complex system-level coordination.

AI summary
A wireless device (1) searches a database that stores positional information of the wireless device (1), a device (2-4) and control identifiers for controlling the devices (2-4) in an associated manner, acquires a device (2-4) located near the wireless device (1) and a control identifier for controlling the device (2-4) based on the positional information of the wireless device (1), and, based on the device (2-4) and the control identifier for controlling the device (2-4) that have been acquired, determines a controlled device (at least one of the devices (2-4)) and generates a control identifier for the controlled device. The wireless device (1) transmits, by wireless communication, the generated controlled identifier to a receiver mounted on the controlled device to control the controlled device.
