Third-Party Server Mediator for Low Power Device Wake

Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing media content delivery systems face challenges in communicating with devices in low power mode, as they often lose the ability to interact with presentation devices that have entered a low power state, especially when these devices are third-party devices, leading to user friction and inefficient power management.

Innovation Solution

The system transmits a request to a third-party server associated with the presentation device to wake it up from the low power mode, allowing the device to remain in a low power state for longer periods while enabling reestablished communication through the third-party server, which then sends a message back to the media providing service once communication is restored.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Use of energy by moving object

If the presentation device enters low power mode to conserve energy, then power consumption is reduced, but the ability to communicate with the device is lost

Engineering Contradiction:

Improvepower consumptionVSAvoidcommunication capability

Core Design Contradiction:

Use of energy by moving objectVSReliability

Solution Approach 1:

The patent introduces a third-party server as an intermediary that maintains communication capability with the presentation device even when it is in low power mode. The media providing service communicates with the third-party server, which then wakes the presentation device when needed, allowing the device to remain in low power state while preserving communication reliability through the intermediary server.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If the media providing service maintains continuous communication with the presentation device, then communication reliability is preserved, but the device cannot enter low power mode for prolonged periods

Engineering Contradiction:

Improvecommunication capabilityVSAvoidpower consumption

Core Design Contradiction:

ReliabilityVSUse of energy by stationary object

Solution Approach 1:

The third-party server acts as a mediator that enables the media providing service to maintain communication reliability without requiring continuous direct communication with the presentation device. The server handles communication during low power states, allowing the device to conserve energy while preserving the ability to communicate when needed.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The system performs preliminary actions by having the third-party server pre-configured to wake the presentation device when communication is needed. This advance preparation allows the device to remain in low power mode longer without compromising communication reliability, as the wake mechanism is already in place when needed.

Inventive Principle:

Principle #10Preliminary action

3Reliability

If the user directly interacts with the presentation device to wake it from low power mode, then communication is reestablished, but user friction and operational complexity increase

Engineering Contradiction:

Improvecommunication reestablishmentVSAvoiduser interaction requirement

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The third-party server serves as an intermediary that automates the wake process. Instead of requiring the user to directly interact with the presentation device to wake it, the media providing service can send commands through the third-party server, which handles the wake operation automatically, thereby reducing user friction and simplifying operation.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The presentation device performs self-service by automatically waking itself when commanded by the third-party server. This eliminates the need for manual user intervention to wake the device, as the system autonomously handles the wake process through the intermediary server, improving ease of operation while maintaining communication reliability.

Inventive Principle:

Principle #25Self-service

AI summary

A first server system is configured to communicate with a first client device through a first application executing on the first client device. The first server system determines that communication with the first client device through the first application has been lost due to the first client device entering an idle mode. The first server system receives a request from a second client device that triggers reestablishing communication with the first client device through the first application. In response, the first server system transmits a request to a second server system to wake the first client device from the idle mode. The first server system receives, from the first application on the first client device, an indication that communication has been reestablished between the first server system and the first application. The first server system transmits a control command to control the first client device.
