Solution Overview

Problem

Caregivers in caregiving sites face burdens due to long periods of watching over multiple care recipients, privacy concerns with video cameras, inability to identify individuals using human detecting sensors, and wasteful labor from unnecessary notifications, especially in private spaces like toilets and baths.

Innovation Solution

An information processing system with sensors to detect entry into rooms, determine if the person is a care recipient or caregiver, and specify the individual, outputting relevant notifications to reduce caregiver burden and improve assistance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If a watching camera is installed to monitor care receivers, then the caregiver burden is reduced, but privacy and dignity of care receivers are impaired

Engineering Contradiction:
Improvecaregiver monitoring efficiencyVSAvoidprivacy violation
Core Design Contradiction:
ProductivityVSObject-affected harmful factors

Solution Approach 1:

The patent extracts only the necessary monitoring information (entry/exit detection, silhouette, action estimation) from the complete video feed, discarding detailed visual information that would violate privacy. This allows monitoring functionality to be maintained while removing the harmful privacy-intrusive elements.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent applies different levels of processing to different aspects of monitoring: full video processing for public areas, silhouette processing for semi-private areas, and skeleton estimation for private areas like toilets and baths. This localized approach to information processing maintains privacy while enabling monitoring where appropriate.

Inventive Principle:
Principle #3Local quality

2Productivity

If a human detecting sensor is installed in private rooms to reduce watching burden, then continuous surveillance is reduced, but precise identification of individuals is lost

Engineering Contradiction:
Improvecaregiver monitoring efficiencyVSAvoidindividual identification information
Core Design Contradiction:
ProductivityVSLoss of information

Solution Approach 1:

The patent performs preliminary registration of care receivers' biometric information (faces, fingerprints, iris patterns) before monitoring begins. This preliminary action enables later automatic identification when the sensor detects someone entering a private room, eliminating the need for continuous surveillance while maintaining precise identification.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent replaces the mechanical approach of visual confirmation by caregivers with automated biometric recognition systems. Sensors detect entry and the system automatically identifies the individual through biometric matching, substituting human visual inspection with automated recognition technology.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

3Speed

If notification is provided for every entry detection to ensure timely response, then response time is improved, but wasteful labor occurs when caregivers rush unnecessarily

Engineering Contradiction:
Improveresponse speedVSAvoidwasteful caregiver time
Core Design Contradiction:
SpeedVSLoss of time

Solution Approach 1:

The patent implements feedback through automatic identification: when a sensor detects entry, the system immediately provides feedback by identifying who entered through biometric recognition. This feedback loop enables caregivers to make informed decisions about whether to respond, preventing wasteful rushes while maintaining rapid response when actually needed.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The system performs preliminary identification of the entrant before triggering a notification response. By pre-identifying who entered the room through biometric recognition, the system allows caregivers to prioritize responses based on actual need, avoiding unnecessary rushes while ensuring timely response to genuine cases.

Inventive Principle:
Principle #10Preliminary action

AI summary

An information processing system includes a sensor that detects entry of a person into a room, and determines whether the person who enters the room is a care recipient as a user of the room or a caregiver who provides care for the user. The information processing system specifies a person who enters the room, and stores an entry detection result by the sensor, a determination result, and a specification result. The information processing system outputs first notification information indicating the entry detection result, second notification information indicating the determination result, and third notification information indicating the specification result to a notification destination.
