Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

In medical facilities, the need for medical professionals to physically interact with patients to measure and register biological information increases the risk of infection and workload, especially when dealing with infectious diseases, due to the limitations of existing NFC-based systems that require professionals to be present for data registration.

Innovation Solution

A biological information input system that allows patients to measure their own vital signs using a measurement instrument with a communication function, such as NFC, and transfers data to a bedside terminal, which is then approved by a medical professional via a separate terminal, reducing the need for direct contact and enabling remote approval.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a medical professional operates the terminal device to register biological information using NFC, then data accuracy and security are ensured, but the medical professional's workload increases and infection risk rises

Engineering Contradiction:

Improvedata accuracyVSAvoidmedical professional workload

Core Design Contradiction:

ReliabilityVSProductivity

Solution Approach 1:

The system divides the data registration process into two independent parts: (1) the measurement instrument automatically captures and transmits biological information via NFC to the terminal device, and (2) the medical professional only performs approval of pre-displayed data. This segmentation eliminates manual data entry while maintaining data accuracy through the professional's verification role.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The measurement instrument performs preliminary data capture and transmission to the terminal device before the medical professional arrives or before the approval step. The data is already prepared and displayed on the screen, so the professional only needs to verify and confirm, significantly reducing their workload while ensuring data reliability.

Inventive Principle:

Principle #10Preliminary action

2Reliability

If a medical professional visits the patient's location to register biological information, then data security is maintained, but the risk of infection transmission increases

Engineering Contradiction:

Improvedata securityVSAvoidinfection risk

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The terminal device acts as an intermediary between the measurement instrument and the electronic medical record system. Biological information is automatically transferred via NFC to the terminal device, which then transmits it to the server. The medical professional interacts only with the terminal device to approve data, eliminating the need to physically contact the patient while maintaining security through controlled access.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The measurement instrument performs self-service by automatically capturing biological information and transmitting it via NFC to the terminal device without requiring medical professional intervention at the patient's bedside. This automation reduces physical contact while the system maintains security through the professional's approval step.

Inventive Principle:

Principle #25Self-service

3Device complexity

If manual data entry is used to input biological information, then system complexity is reduced, but time consumption and potential for errors increase

Engineering Contradiction:

Improvesystem simplicityVSAvoiddata registration time

Core Design Contradiction:

Device complexityVSLoss of time

Solution Approach 1:

The system replaces the mechanical process of manual data entry with automated NFC (Near Field Communication) technology. The measurement instrument wirelessly transmits biological information to the terminal device, eliminating the need for manual typing while keeping the overall system relatively simple through the use of standard NFC protocols and a straightforward approval interface.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

AI summary

A biological information input system includes: a measurement instrument having a communication function and configured to measure biological information of a person under measurement; and a first terminal device having a communication function capable of communicating with the communication function of the measurement instrument, and configured to receive, via the communication function, the biological information associated with the person under measurement and measured by the measurement instrument. The biological information input system displays a screen with which a person having authority to approve the biological information approves first data including the biological information and information related to the person under measurement.
