Solution Overview

Problem

Endoscopes can become contaminated and develop biofilm when not promptly reprocessed, leading to difficulty in cleaning and increased contamination risk due to drying of adherent materials.

Innovation Solution

A liner for an endoscope storage tray with a flexibly deformable, impermeable material and an absorbent layer to maintain a moist environment, combined with a detergent system to keep the endoscope moist and a timing mechanism to monitor storage time.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If the endoscope is stored in a dry environment after use, then the storage is simple and convenient, but the adherent material and biofilm dry and become difficult to remove

Engineering Contradiction:
Improveease of storageVSAvoidease of cleaning
Core Design Contradiction:
Ease of manufactureVSEase of repair

Solution Approach 1:

An absorbent liner is introduced as an intermediary between the endoscope and the storage environment. The liner maintains a moist microenvironment around the endoscope without requiring complex external systems, thus keeping storage simple while preventing drying of the endoscope surface and channels.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The local humidity parameter around the endoscope is changed by using an absorbent liner that can maintain moisture. This creates a moist storage environment that prevents biofilm drying and adhesion, making subsequent cleaning easier while keeping the overall storage system simple.

Inventive Principle:
Principle #35Parameter changes

2Reliability

If detergent is applied to the endoscope immediately after use, then biofilm formation is prevented, but the reprocessing time and complexity increase

Engineering Contradiction:
Improvecontamination preventionVSAvoidreprocessing time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The absorbent liner is prepared in advance with detergent solution before the endoscope is placed in storage. This preliminary action ensures that the endoscope is already exposed to detergent, preventing biofilm formation during storage without requiring additional reprocessing steps later.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The liner automatically maintains contact with the endoscope surface and channels during storage, providing continuous detergent exposure without requiring active intervention. The system serves itself by maintaining the protective moist detergent environment passively throughout the storage period.

Inventive Principle:
Principle #25Self-service

3Adaptability or versatility

If the endoscope is stored for extended periods before reprocessing, then scheduling flexibility is improved, but the risk of biofilm formation and drying increases

Engineering Contradiction:
Improvescheduling flexibilityVSAvoidcontamination risk
Core Design Contradiction:
Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

The absorbent liner acts as a protective intermediary that maintains a controlled moist environment around the endoscope during extended storage. This mediator prevents harmful drying and biofilm formation, enabling flexible scheduling without increasing contamination risk.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The liner continuously maintains the moist protective environment throughout the entire storage period, ensuring uninterrupted prevention of biofilm formation and drying. This continuous action allows extended storage times while maintaining endoscope cleanliness and safety.

Inventive Principle:
Principle #20Continuity of useful action
