Communicating Device Proxy Notification Feedback Mechanism

Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Users are not notified whether a proxy process has started or terminated in response to their instructions in existing NAN standard-based proxy processing systems, leading to a need for improved notification mechanisms.

Innovation Solution

A communicating device is designed to request a proxy device to start or terminate a notification of service information based on the NAN standard, and to obtain and provide execution information to the user regarding the proxy process, ensuring proper notification of proxy process status.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Use of energy by moving object

If a proxy process is requested to start or terminate notification of service information, then the device can operate in DOZE state for longer periods reducing power consumption, but the user is not notified whether the proxy process has started or terminated

Engineering Contradiction:

Improvepower consumptionVSAvoidnotification information

Core Design Contradiction:

Use of energy by moving objectVSLoss of information

Solution Approach 1:

The patent implements a feedback mechanism where the communicating device receives execution information from the proxy device indicating whether the proxy process has started or terminated, and then notifies the user based on this feedback. This resolves the contradiction by providing necessary notification information while still allowing the device to operate in low-power DOZE state for extended periods.

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The communicating device itself performs the notification function using the execution information received from the proxy device, rather than requiring the proxy device to directly notify the user. This self-service approach allows the communicating device to maintain control over notification while operating in power-saving mode.

Inventive Principle:

Principle #25Self-service

2Loss of information

If the device continuously monitors proxy process status, then the user receives timely notifications, but the device cannot maintain DOZE state for longer periods

Engineering Contradiction:

Improvenotification informationVSAvoidpower consumption

Core Design Contradiction:

Loss of informationVSUse of energy by moving object

Solution Approach 1:

Instead of continuous monitoring, the device uses periodic action by setting up a proxy process request that automatically returns execution information when the proxy process starts or terminates. This allows the device to remain in DOZE state and only wake up when necessary to receive or send notification, resolving the contradiction between timely notification and power consumption.

Inventive Principle:

Principle #19Periodic action

3Loss of information

If the proxy device directly notifies the user, then notification is provided, but the communicating device cannot control the notification process

Engineering Contradiction:

Improvenotification informationVSAvoiddevice control

Core Design Contradiction:

Loss of informationVSEase of operation

Solution Approach 1:

The patent uses the execution information as an intermediary between the proxy device and the user notification process. The communicating device receives this intermediate data and then controls the actual notification to the user, maintaining ease of operation and device control while still providing necessary notification information.

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

In a case where a communicating device requests a proxy device to execute a notification of service information provided by the communicating device or requests the proxy device to start or termination a search of service information provided by another communicating device, the communicating device performs a notification based on a response to the request to a user.
