Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Electronic devices receive unnecessary broadcasted messages for external device registration, leading to user inconvenience and increased message transmission.

Innovation Solution

Provide a message for external device registration only when both a broadcasted request signal and a nonaudible frequency signal are received, allowing the electronic device to determine and selectively respond to the request.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the electronic device automatically outputs a setup message for registering an external device upon receiving a BLE signal, then the external device registration function is provided, but unnecessary messages are transmitted to users causing inconvenience

Engineering Contradiction:

Improveexternal device registration functionVSAvoiduser convenience

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The electronic device performs preliminary actions by transmitting a non-audible frequency signal before automatically outputting the setup message. This preliminary signal serves as a trigger to activate the automatic message output only under specific conditions, preventing unnecessary messages from being transmitted while maintaining the automated registration function.

Inventive Principle:

Principle #10Preliminary action

2Productivity

If the electronic device transmits setup messages for all received BLE signals, then all external devices can be registered, but the number of unnecessary message transmissions increases

Engineering Contradiction:

Improvedevice registration capabilityVSAvoidmessage transmission overhead

Core Design Contradiction:

ProductivityVSLoss of energy

Solution Approach 1:

The system changes the parameter of signal detection by introducing a non-audible frequency signal as an additional condition. Instead of responding to all BLE signals, the electronic device now requires both the BLE signal and the non-audible frequency signal to be detected, thereby filtering out unnecessary registration messages and reducing transmission overhead.

Inventive Principle:

Principle #35Parameter changes

3Extent of automation

If the electronic device outputs setup messages automatically, then the registration process is simplified, but unwanted notifications are generated

Engineering Contradiction:

Improveautomatic registration processVSAvoidunwanted notifications

Core Design Contradiction:

Extent of automationVSObject-generated harmful factors

Solution Approach 1:

The non-audible frequency signal acts as an intermediary trigger between the BLE signal reception and the automatic setup message output. This intermediary condition ensures that the automated registration process is activated only when appropriate, preventing unwanted notifications while maintaining the simplified automatic process.

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

A method for controlling a signal related to an external device and an electronic device therefor are provided. The electronic device includes a transceiver, a memory, and at least one processor. The at least one processor is configured to control to receive a broadcasted request signal for registering an external device, from the external device via the transceiver, identify whether a nonaudible frequency signal is received from the external device, and provide a message for registering the external device based on the nonaudible frequency signal being received.
