Solution Overview

Problem

Current sanitization methods for air conditioning systems are inefficient, time-consuming, and pose health risks to operators due to the need for manual disassembly and the use of high-pressure steam jets, which can cause condensation and increase energy consumption.

Innovation Solution

A device with a compact delivering head and suction opening, allowing for precise and safe delivery of sanitizing fluid jets and simultaneous suction of condensation, enabling sanitization of air conditioning units without protective housings and reducing labor costs by allowing non-skilled personnel to operate it efficiently.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If manual cleaning with microfiber cloths and germicidal products is used, then sanitization effectiveness is improved, but labor cost and time consumption increase significantly

Engineering Contradiction:
Improvesanitization effectivenessVSAvoidsanitization speed
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The patent replaces manual mechanical cleaning operations with an automated sanitizing device that uses high-pressure steam jets and suction mechanisms. The device automatically delivers sanitizing fluid through nozzles and simultaneously removes condensation and contaminants via suction openings, eliminating the need for manual disassembly and cleaning with cloths.

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

Solution Approach 2:

The device enables self-service sanitization by automatically performing both the delivery of sanitizing fluid and the removal of condensation without requiring skilled operators. The integrated system allows non-skilled personnel to operate the device, which autonomously completes the sanitization process including fluid delivery, condensation removal, and contaminant extraction.

Inventive Principle:
Principle #25Self-service

2Productivity

If high-pressure steam jets are used for sanitization, then sanitization speed is improved, but condensation forms that can dirty walls, floor, or furniture

Engineering Contradiction:
Improvesanitization speedVSAvoidcondensation pollution
Core Design Contradiction:
ProductivityVSObject-generated harmful factors

Solution Approach 1:

The patent introduces suction openings as an intermediary mechanism between the steam jet delivery and the surrounding environment. These suction openings actively capture and remove condensation as it forms, preventing it from reaching and dirtying walls, floors, or furniture. The suction system acts as a mediator that intercepts the harmful condensation byproduct.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent converts the harmful condensation byproduct into a beneficial controlled process. Instead of allowing condensation to pollute the environment, the system uses suction to capture it and redirect it to a collection container. The harmful condensation is transformed from a pollution source into a contained byproduct that can be properly disposed of.

Inventive Principle:
Principle #22Blessing in disguise (Convert harm into benefit)

3Object-affected harmful factors

If protective housings are used to contain steam, then operator safety is improved, but device complexity and execution time increase

Engineering Contradiction:
Improveoperator safetyVSAvoidhousing structure
Core Design Contradiction:
Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The patent extracts the essential safety function from the complex protective housing structure. Instead of using a large enclosing housing to protect operators, the invention extracts the protective function into targeted suction openings and localized shielding elements that are positioned only where condensation and steam pose risks. This eliminates the need for comprehensive housing structures.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent segments the protective function into discrete localized elements rather than using a single comprehensive housing. The suction openings are positioned at specific locations where steam and condensation are generated, providing targeted protection only where needed. This segmented approach reduces overall device complexity while maintaining safety.

Inventive Principle:
Principle #1Segmentation

4Reliability

If the suction opening is sized to engage the entire unit, then complete containment is achieved, but the device cannot be moved to sanitize different portions

Engineering Contradiction:
Improvecontainment completenessVSAvoidpositioning flexibility
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent makes the suction opening configuration dynamic by allowing it to be positioned at multiple locations on the air conditioner unit. The suction opening can be moved from one portion of the unit to another, enabling the device to adapt to different sanitization needs while maintaining effective containment and removal of condensation and contaminants at each position.

Inventive Principle:
Principle #15Dynamics
