Solution Overview

Problem

Existing cleaning and disinfection devices for medical hollow body instruments require separate steps for internal and external cleaning, disinfection, and care, leading to cumbersome handling and unreliable process reliability due to manual intervention or lack of reproducibility.

Innovation Solution

A cleaning and disinfection device with a media interface that integrates supply lines for cleaning agents, compressed air, and care products, allowing simultaneous internal and external processing of hollow body instruments, including automated care through compressed air distribution.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If separate steps are used for internal and external cleaning, disinfection, and care, then each step can be performed with dedicated equipment, but the handling becomes cumbersome and process reliability decreases

Engineering Contradiction:
Improveprocess reliabilityVSAvoidhandling
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The patent combines multiple separate processing steps (external cleaning, internal cleaning, disinfection, and care) into a single integrated treatment chamber where all operations can be performed simultaneously or sequentially on the hollow body instrument without manual intervention between steps, thereby improving both reliability and ease of operation

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The treatment chamber is designed to perform multiple functions: external spray cleaning, internal feeding cleaning, thermal disinfection through heating elements, and care product application. This multi-functional design eliminates the need for separate equipment for each step, improving process reliability while simplifying handling

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Reliability

If manual intervention is used for care steps, then flexibility is maintained, but reproducibility and reliability of the process decrease

Engineering Contradiction:
ImprovereproducibilityVSAvoidautomation system
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The system automatically performs all processing steps including care product application without requiring manual intervention. The control unit manages the sequence of operations, media supply, and parameter control, ensuring reproducible results while the automation complexity is contained within the device itself rather than requiring complex external systems

Inventive Principle:
Principle #25Self-service

3Productivity

If multiple separate processing steps are used, then each step can be optimized independently, but the overall process time and complexity increase

Engineering Contradiction:
Improveprocess timeVSAvoidsystem integration
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

Multiple processing steps are merged into a single treatment chamber that can perform external cleaning, internal cleaning, disinfection, and care application in one continuous process, significantly reducing total process time while the integration complexity is managed through a unified design rather than multiple separate systems

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The system enables continuous processing where the instrument moves through different treatment zones or stages without interruption. The spray device, feeding device, and heating elements operate in a coordinated continuous sequence, maximizing productivity while the control system manages the complexity of coordinating multiple simultaneous actions

Inventive Principle:
Principle #20Continuity of useful action
