Solution Overview

Problem

Existing evaluation systems for cognitive function do not efficiently differentiate between normal and deteriorated cognitive states, leading to unnecessary burden on guardians and lack of convenience.

Innovation Solution

An evaluation system that includes an information acquiring unit to gather pay information, an evaluating unit to assess cognitive function, and a determining unit to trigger evaluations based on pay information, thereby reducing unnecessary notifications and improving convenience.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the system transmits purchase notification to the guardian for every purchase made by the target person, then the guardian can always know about the purchase state, but the burden on the guardian increases due to receiving unnecessary notifications

Engineering Contradiction:

Improvenotification reliabilityVSAvoidguardian burden

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The system changes the parameter of notification transmission from unconditional (every purchase) to conditional (only when cognitive function deterioration is suspected). The determining unit evaluates multiple parameters including purchase timing, item category, and amount to decide whether to transmit notifications, thereby reducing unnecessary notifications while maintaining reliability for significant events.

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The system introduces an intermediary evaluation mechanism between the purchase detection and notification transmission. The determining unit acts as a mediator that filters purchase notifications based on cognitive function assessment, preventing direct transmission of all notifications to the guardian and reducing their burden.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Measurement precision

If the system performs cognitive function evaluation for every purchase, then the cognitive state can be continuously monitored, but the system complexity and processing burden increase

Engineering Contradiction:

Improvecognitive function monitoring precisionVSAvoidsystem complexity

Core Design Contradiction:

Measurement precisionVSDevice complexity

Solution Approach 1:

The system performs cognitive function evaluation partially rather than for every purchase. The determining unit selectively triggers evaluation only when specific conditions are met (unusual purchase timing, inappropriate item category, excessive amount), reducing system complexity while maintaining sufficient monitoring precision for detecting cognitive deterioration.

Inventive Principle:

Principle #16Partial or excessive action

Solution Approach 2:

The system applies different evaluation strictness to different purchase scenarios. High-risk purchases (late-night, inappropriate items, large amounts) trigger cognitive evaluation, while normal purchases do not. This local differentiation reduces overall system complexity while maintaining high monitoring precision where needed.

Inventive Principle:

Principle #3Local quality

AI summary

An evaluation system includes an information acquiring unit, an evaluating unit, and a determining unit. The information acquiring unit is configured to acquire pay information relating to a consideration which a target person should pay for reception of service. The evaluating unit is configured to evaluate a cognitive function of the target person. The determining unit is configured to determine, by using acquiring of the pay information as a trigger, whether or not an evaluation for the cognitive function of the target person by the evaluating unit is required.
