Solution Overview

Problem

Existing display apparatuses, such as digital TVs, cannot efficiently receive and connect to video calls when turned off, leading to missed calls and unnecessary power consumption, as they require constant operation to handle incoming video communications.

Innovation Solution

A method and apparatus that include a communication module and controller in the display apparatus, allowing it to be turned on by an external device's control signal when a video call is received, enabling connection to the call and reducing power usage by only activating when necessary.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Use of energy by moving object

If the display apparatus remains turned off to save power, then power consumption is reduced, but video calls cannot be received and connected

Engineering Contradiction:
Improvepower consumptionVSAvoidvideo call connectivity
Core Design Contradiction:
Use of energy by moving objectVSReliability

Solution Approach 1:

The display apparatus performs preliminary registration of identification information (phone number, email, or social network ID) for video calls before actually receiving a call. When a video call is received, the apparatus can quickly connect using pre-configured information without needing to be fully powered on beforehand, thus saving power while maintaining connectivity reliability

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The communication module acts as an intermediary that can receive video call signals even when the main display apparatus is in a low-power state. The module receives the call signal and transmits it to the controller, which then activates the display apparatus to complete the connection, serving as a bridge between the low-power state and full operational state

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If the display apparatus is constantly turned on to receive video calls, then video call connectivity is maintained, but power consumption increases

Engineering Contradiction:
Improvevideo call connectivityVSAvoidpower consumption
Core Design Contradiction:
ReliabilityVSUse of energy by moving object

Solution Approach 1:

Instead of continuous operation, the display apparatus uses periodic action by activating only when needed. The communication module periodically checks for incoming calls while the main system remains in low-power mode. When a call is detected, the apparatus activates to complete the connection, then returns to low-power state after the call, creating a rhythm of activation that reduces overall power consumption while maintaining connectivity

Inventive Principle:
Principle #19Periodic action

Solution Approach 2:

The display apparatus serves itself by automatically activating in response to received video call signals without requiring manual user intervention. The controller monitors incoming signals and autonomously decides when to activate the display apparatus, managing its own power consumption based on actual usage needs rather than continuous operation

Inventive Principle:
Principle #25Self-service

3Ease of operation

If the display apparatus automatically turns on when a video call is received, then connectivity is improved, but power consumption increases compared to staying off

Engineering Contradiction:
Improvevideo call connection easeVSAvoidpower consumption
Core Design Contradiction:
Ease of operationVSUse of energy by moving object

Solution Approach 1:

The display apparatus performs self-service by automatically activating itself when a video call is received, eliminating the need for manual user intervention to turn on the device. The controller autonomously detects the incoming call signal and activates the display apparatus, making the connection process easier while minimizing power consumption by only activating when absolutely necessary

Inventive Principle:
Principle #25Self-service
