Problem

Existing technologies face challenges in remotely controlling devices that share real-time content streams across different spaces and synchronizing remote control operations in various locations, particularly in family settings where multiple devices are connected through a television-based cloud system.

Innovation Solution

A method and system that allows a mobile terminal to send remote control requests to a television, which responds with signals indicating user presence, enabling time-domain synchronization and permitting remote control of devices providing real-time content, using a network connection, infrared transmission, and user detection through image processing and face identification.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the television shares real-time content streams with multiple devices across different spaces, then the adaptability and accessibility of the system is improved, but the difficulty of detecting and measuring user presence and synchronizing remote control operations increases

Engineering Contradiction:
Improvecontent sharing capabilityVSAvoiduser presence detection
Core Design Contradiction:
Adaptability or versatilityVSDifficulty of detecting and measuring

Solution Approach 1:

The patent introduces an intermediary system comprising the television set with camera and processor that mediates between multiple user devices and the content source. The television detects user presence through its camera and processes this information to determine which device should receive remote control signals, thereby simplifying the complexity that would otherwise exist in directly coordinating all devices with each other.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The system implements feedback by continuously monitoring user presence through the television's camera and using this information to dynamically control which device can send remote control commands. The television provides feedback signals to connected devices based on detected user presence, enabling automatic synchronization without requiring complex peer-to-peer communication between all devices.

Inventive Principle:
Principle #23Feedback

2Ease of operation

If remote control operations are allowed from any device in any space, then the ease of operation is improved, but the reliability of synchronized control decreases

Engineering Contradiction:
Improveremote control accessibilityVSAvoidcontrol synchronization
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The system enables self-service by allowing any connected device to potentially control the content source, but the television automatically manages control rights based on user presence detection. Devices can send control requests freely, and the television autonomously determines whether to permit them based on camera detection, eliminating the need for users to manually negotiate control rights while maintaining reliable synchronization.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The television performs preliminary detection of user presence before allowing remote control operations from distant devices. By detecting whether someone is present in front of the television beforehand, the system can pre-determine which device should have control rights, ensuring synchronized operation before control commands are executed.

Inventive Principle:
Principle #10Preliminary action

3Reliability

If the system monitors user presence continuously to enable accurate remote control authorization, then the reliability of control synchronization is improved, but the use of energy increases

Engineering Contradiction:
Improvecontrol synchronization accuracyVSAvoidenergy consumption
Core Design Contradiction:
ReliabilityVSUse of energy by moving object

Solution Approach 1:

The system implements periodic user presence detection rather than continuous monitoring. The television's camera and processor periodically check for users in front of the device and update control authorization based on these periodic checks. This approach maintains reliable synchronization by detecting user presence at appropriate intervals while significantly reducing energy consumption compared to continuous monitoring.

Inventive Principle:
Principle #19Periodic action
