Solution Overview

Problem

The existing system requires evaluators to manually check each input data item for correctness, leading to a high operational burden and increased time for data evaluation.

Innovation Solution

A reliability determination system that measures the movement of the operator's center of gravity using sensors and calculates the center-of-gravity sway area to determine data reliability, reducing the need for manual evaluation by associating the reliability with input data in a database.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If manual checking of each input data item is performed, then data correctness can be confirmed, but the operational burden and time required for evaluation increases

Engineering Contradiction:

Improvedata correctnessVSAvoidevaluation time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The system performs preliminary actions by measuring the operator's center of gravity movement during data input and pre-determining reliability indicators before the evaluator receives the data. This allows the evaluator to quickly identify high-reliability data that requires minimal checking, reducing overall evaluation time while maintaining correctness verification for necessary items

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent replaces the mechanical manual checking process with an automated measurement system that uses sensors to detect center of gravity movement. This substitution creates an objective reliability indicator that reduces the need for time-consuming manual verification of each data item

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Reliability

If manual checking of each input data item is performed, then data correctness can be confirmed, but the operational burden on the evaluator increases

Engineering Contradiction:

Improvedata correctnessVSAvoidevaluator burden

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The system replaces the evaluator's manual checking operations with an automated center of gravity measurement system. The measurement unit objectively assesses operator concentration through physical measurements, eliminating the need for evaluators to manually verify each data item's correctness, thus reducing operational burden

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The system enables self-service by allowing the data input process itself to generate reliability information through center of gravity measurement. The evaluator receives pre-processed data with attached reliability indicators, making the evaluation process easier and more efficient

Inventive Principle:

Principle #25Self-service
