Solution Overview

Problem

Current medical treatment systems face challenges in ensuring patient safety due to the time-consuming and error-prone process of entering treatment data, which can lead to incorrect parameter settings and potential harm to patients.

Innovation Solution

A medical treatment system comprising a medical treatment device and a therapy frame device, where the medical treatment device generates a patient and treatment-related requirement code that includes patient identity data, and the therapy frame device produces an approval code using a computer or microprocessor, which is then used to unlock the medical treatment device for the selected treatment.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If treatment data is manually entered, then the treatment process can be initiated, but the process is time-consuming and error-prone leading to incorrect parameter settings

Engineering Contradiction:
Improvepatient safetyVSAvoidtime for data entry
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The patent uses graphical codes (barcodes, QR codes, flicker codes) as copies of treatment data that can be scanned and automatically transferred to the medical device. This eliminates manual data entry while ensuring accuracy, as the code contains encoded patient and treatment parameters that are directly read by the system.

Inventive Principle:
Principle #26Copying

Solution Approach 2:

The patent replaces the mechanical process of manual data entry with an optical scanning system. The graphical code is read optically by a scanner, automatically decoded, and transferred to the treatment device, substituting the manual typing process with an automated optical recognition system.

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

2Reliability

If treatment data is manually entered, then the treatment can be set up, but incorrect parameter entry can lead to inappropriate patient settings and potential harm

Engineering Contradiction:
Improvetreatment accuracyVSAvoidrisk of patient injury
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The graphical code serves as an accurate copy of the treatment prescription, containing encoded patient identity and treatment parameters. Scanning this code ensures that the exact prescribed parameters are transferred without manual entry errors, eliminating the risk of incorrect settings.

Inventive Principle:
Principle #26Copying

Solution Approach 2:

The system provides feedback by displaying the decoded parameters from the graphical code on the device screen before final confirmation. This allows verification of the transferred data and prevents erroneous treatment parameters from being applied to the patient.

Inventive Principle:
Principle #23Feedback

3Reliability

If authorization procedures are implemented, then patient safety is improved, but the treatment process becomes more complex

Engineering Contradiction:
Improvepatient safetyVSAvoidsystem complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The graphical code acts as an intermediary carrier that contains and transmits treatment authorization information. Instead of complex direct verification procedures, the system uses the coded information as a mediator that automatically conveys patient identity and treatment parameters to the authorization system.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The authorization data is copied into the graphical code format, which can be easily scanned and verified. This simplifies the authorization process by converting complex verification requirements into a scannable code format that the system can automatically process.

Inventive Principle:
Principle #26Copying

4Ease of operation

If data entry is required, then treatment parameters can be input, but the process is prone to errors and shock to patients

Engineering Contradiction:
Improvedata input processVSAvoidparameter accuracy
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

Treatment parameters are copied into graphical code format and automatically transferred via scanning. This eliminates manual data input entirely, removing the source of human error while maintaining ease of operation through simple scan-and-treat workflow.

Inventive Principle:
Principle #26Copying

Solution Approach 2:

The manual mechanical process of typing and entering parameters is replaced with automated optical scanning and digital decoding. This substitution eliminates keyboard input errors and ensures accurate parameter transfer from the prescription to the treatment device.

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