Solution Overview

Problem

Picture display devices like televisions shared by multiple users face usability issues as each user's preference for settings such as picture quality may differ, requiring manual adjustment, which is time-consuming and inefficient.

Innovation Solution

A picture display device equipped with an individual information storage unit, operator identification unit, and control unit to identify users and automatically apply personalized settings based on stored user information.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If manual setting adjustment is performed for each user, then picture quality can be optimized for individual preferences, but time and labor consumption increase significantly

Engineering Contradiction:

Improvesetting adjustment convenienceVSAvoidtime for setting adjustment

Core Design Contradiction:

Ease of operationVSLoss of time

Solution Approach 1:

The system automatically identifies the user and applies their personalized settings without requiring manual intervention. The operator identification unit detects who is using the device, and the control unit automatically loads the corresponding pre-configured settings, making the system serve itself rather than requiring user effort for setting adjustment.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

Settings are pre-configured and stored in association with operator information before the user actually needs to use the device. When a user operates the device, their settings are already prepared and can be immediately applied through automatic identification, eliminating the need for real-time manual adjustment.

Inventive Principle:

Principle #10Preliminary action

2Adaptability or versatility

If settings are manually adjusted for each user, then individual preferences can be accommodated, but operational complexity increases

Engineering Contradiction:

Improveuser preference adaptationVSAvoidsetting adjustment process

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

Operator information serves as an intermediary that links users to their preferred settings. Instead of directly complex manual adjustment processes, the system uses operator identification as a mediator to automatically retrieve and apply the appropriate settings, simplifying the overall operational complexity while maintaining adaptability.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The system creates a copy of operator information and associates it with their preferred settings in a storage unit. When the operator is identified, the system retrieves this pre-created association, allowing multiple users to have their unique preferences stored and automatically applied without complex real-time configuration processes.

Inventive Principle:

Principle #26Copying

3Ease of operation

If automatic user identification and setting application is implemented, then usability for multiple users is improved, but device complexity increases

Engineering Contradiction:

Improveusability for multiple usersVSAvoidsystem structure

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The operator identification unit and control unit work together to provide universal functionality across multiple users. The same identification and setting application mechanism serves all users, making the added complexity worthwhile through multi-user adaptability and personalized service.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The system segments user information and settings into distinct operator information records stored in association with each other. This segmentation allows the control unit to efficiently retrieve and apply the correct settings for the identified operator, managing complexity through organized data structure while enabling multi-user personalization.

Inventive Principle:

Principle #1Segmentation

AI summary

A picture display apparatus able to display content includes a network interface that can communicate with a portable terminal via a first network and acquire the content via a second network, and further includes a controller and a display capable of displaying the content and a content list of the content capable of being acquired via the second network. The content list settings information and operator information are stored in a storage in association with each other. When the controller determines that operator information acquired from the portable terminal is not operator information related to an operator stored in the storage, but instead is operator information regarding a new operator, the controller performs a control that enables processing to newly store operator information about the new operator in the storage without displaying, on the display, a content list based on content list settings information corresponding to operator information.
