Solution Overview

Problem

Existing systems fail to accurately determine the appropriate approach to a subject based on their state and task execution situation, particularly when tasks are performed continuously or intermittently.

Innovation Solution

An information processing device that acquires task evaluation information, estimates the subject's state, and determines an appropriate mode of intervention using a combination of task evaluation indices and state indices, such as concentration, arousal, and tension levels, to optimize task execution.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If the system provides approaches to the subject at each task completion timing, then task performance efficiency is improved, but the accuracy of determining the appropriate approach mode deteriorates because the system lacks sufficient information about the subject's state and task execution situation

Engineering Contradiction:

Improvetask performance efficiencyVSAvoidaccuracy of approach mode determination

Core Design Contradiction:

ProductivityVSMeasurement precision

Solution Approach 1:

The system performs preliminary actions by acquiring task evaluation information before determining the approach mode. The acquisition unit collects information about the task execution situation in advance, which then serves as the basis for the determination unit to accurately select the appropriate approach mode, resolving the contradiction between providing frequent approaches and determining them accurately

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system implements feedback by using task evaluation information to adjust and refine the approach mode determination. The determination unit receives feedback from the acquired task evaluation information and adjusts its decision-making process, enabling accurate determination of approach modes while maintaining efficient task performance

Inventive Principle:

Principle #23Feedback

2Speed

If the system determines approach modes based on limited information, then the determination speed is improved, but the accuracy of the determined approach mode deteriorates

Engineering Contradiction:

Improvedetermination speedVSAvoidaccuracy of approach mode determination

Core Design Contradiction:

SpeedVSMeasurement precision

Solution Approach 1:

The acquisition unit performs preliminary information gathering before the determination process. By acquiring task evaluation information in advance, the determination unit has sufficient data ready for rapid and accurate decision-making, eliminating the need to choose between speed and accuracy

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The determination unit is designed to handle multiple aspects of approach mode determination using the acquired task evaluation information. This multi-functional approach allows the system to maintain both speed and accuracy by processing various types of information simultaneously rather than sequentially

Inventive Principle:

Principle #6Universality (Multi-functionality)
