Solution Overview

Problem

Current diffuser systems for disinfecting spaces and surfaces lack assurance of correct sanitization treatment, as they rely on single devices that cannot guarantee the accuracy or certification of disinfection processes, leading to potential incomplete or ineffective disinfection.

Innovation Solution

A diffuser method and device equipped with a tank, nebulizing means, and a control unit that uses sensors and a separate fragrance solution to ensure accurate dispensing of disinfectant, allowing immediate sensory verification of treatment completion and automatic quantity control based on room identification data.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If a single diffuser device is used for disinfection, then the device complexity is reduced, but the reliability of disinfection certification is insufficient

Engineering Contradiction:

Improvedevice complexityVSAvoiddisinfection certification reliability

Core Design Contradiction:

Device complexityVSReliability

Solution Approach 1:

The system is divided into multiple functional modules: diffuser device, control device, and identification device. Each module performs a specific function (disinfection, control, and verification), allowing the system to achieve reliable disinfection certification without requiring a single overly complex device. The segmentation enables independent verification of disinfection parameters.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The control device acts as an intermediary between the diffuser device and the identification device. It receives identification data, controls the diffuser operation, and transmits disinfection parameter data to the identification device for certification. This intermediary role ensures proper coordination and reliable certification without increasing the complexity of individual components.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Ease of operation

If manual operation and verification are used, then the ease of operation is improved, but the productivity and accuracy of disinfection are reduced

Engineering Contradiction:

Improveease of operationVSAvoiddisinfection efficiency

Core Design Contradiction:

Ease of operationVSProductivity

Solution Approach 1:

The system performs automatic identification, control, and verification functions without requiring manual intervention. The identification device automatically reads room identification data, the control device automatically controls the diffuser based on the data, and the system automatically transmits and stores disinfection parameter data. This self-service capability significantly improves disinfection efficiency and accuracy.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The system implements automatic feedback loops where the identification device provides room identification data to the control device, which then adjusts diffuser operation parameters accordingly. The disinfection parameter data is automatically transmitted back for verification and storage, ensuring accurate and efficient disinfection without manual intervention.

Inventive Principle:

Principle #23Feedback

3Measurement precision

If operator verification is required, then the measurement precision of disinfection parameters is improved, but the loss of time increases

Engineering Contradiction:

Improvedisinfection parameter accuracyVSAvoidverification time

Core Design Contradiction:

Measurement precisionVSLoss of time

Solution Approach 1:

The system replaces manual operator verification with automated electronic identification and data transmission. The identification device automatically reads and verifies room identification data, and the control device automatically transmits disinfection parameter data for verification. This substitution of mechanical/manual verification with automated electronic systems maintains measurement precision while eliminating time loss.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)
