Solution Overview

Problem

Conventional communication systems do not prioritize incoming calls and emails effectively while a user is watching a TV program, leading to inconvenience for both the user and the caller, as they do not consider the importance of the caller or the program, and fail to inform the caller of the TV program's end time.

Innovation Solution

A communication terminal equipped with a video reproduction device, a communication device, and a reproduction-end-time acquisition device that informs the caller of the TV program's end time if a call is received during video reproduction, allowing the caller to schedule a follow-up call accordingly, and prioritizes notifications based on set conditions such as caller importance and program significance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If the TV system displays email-arrival-displaying screen after a program scene is replaced by a commercial screen, then the user can see email arrivals, but the user is not immediately informed of important communications during video reproduction

Engineering Contradiction:
Improveinformation delivery timingVSAvoiduser convenience
Core Design Contradiction:
Loss of informationVSEase of operation

Solution Approach 1:

The system performs preliminary action by notifying the communication partner of the video reproduction end time before the reproduction actually ends. This allows the partner to schedule follow-up communications appropriately, ensuring important information is not lost due to timing issues during video playback.

Inventive Principle:
Principle #10Preliminary action

2Duration of action of stationary object

If incoming communications are reported later without considering priorities, then the TV program can be watched continuously, but important phone calls or emails may be delayed

Engineering Contradiction:
Improvevideo reproduction continuityVSAvoidcommunication priority handling
Core Design Contradiction:
Duration of action of stationary objectVSReliability

Solution Approach 1:

The system implements feedback by informing the communication partner about the video reproduction end time and priority-based notification status. This feedback loop allows the partner to understand when to expect responses, maintaining both video continuity and communication reliability through informed scheduling.

Inventive Principle:
Principle #23Feedback

3Device complexity

If the phone-call maker is not informed of the TV program end time, then the system operates simply, but the phone-call maker must make repeated calls to reach the user

Engineering Contradiction:
Improvesystem simplicityVSAvoidtime for repeated call attempts
Core Design Contradiction:
Device complexityVSLoss of time

Solution Approach 1:

The system performs preliminary action by providing the communication partner with the video reproduction end time in advance. This allows the partner to plan follow-up calls efficiently, eliminating the need for repeated call attempts and reducing time loss without significantly increasing system complexity.

Inventive Principle:
Principle #10Preliminary action

AI summary

A communication terminal comprising a video reproduction device configured to carry out a video reproduction, a communication device configured to carry out a communication; and a reproduction-end-time acquisition device configured to acquire an end time of the video reproduction carried out by said video reproduction device. When an incoming communication arrives from a communication partner terminal in the course of the video reproduction carried out by said video reproduction device, the communication partner terminal is informed of the end time of said video reproduction. The communication partner terminal is external to the communication terminal.
