Solution Overview

Problem

Existing endoscope cleaning/disinfecting apparatuses face challenges in efficiently controlling and checking the concentration of medicinal solutions, often requiring separate conduits and complex procedures for concentration verification.

Innovation Solution

An endoscope cleaning/disinfecting apparatus with a medicinal solution storage portion positioned below a cleaning/disinfecting tank, connected by a conduit with a check valve and a medicinal solution receiving member that allows gravity-fed flow, enabling easy concentration checking without the need for additional collection conduits or complex setups.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Use of energy by stationary object

If the medicinal solution storage portion is positioned below the cleaning/disinfecting tank to enable gravity-fed flow, then energy consumption is reduced and system simplicity is improved, but control over solution flow and concentration becomes more difficult

Engineering Contradiction:
Improveenergy consumptionVSAvoidflow control
Core Design Contradiction:
Use of energy by stationary objectVSEase of operation

Solution Approach 1:

The system uses gravity as the driving force for medicinal solution flow, eliminating the need for external pumps or power sources. The check valve automatically controls the flow direction without requiring active control mechanisms, achieving self-regulated gravity-fed flow from the storage portion to the cleaning tank.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

A check valve is introduced as an intermediary component in the flow path to control the directional flow of medicinal solution. The check valve allows solution to flow from the storage portion to the cleaning tank while preventing backflow, providing passive flow control without requiring active mechanical or electrical systems.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of operation

If a check valve is added to control gravity-fed flow, then flow control capability is improved, but device complexity increases

Engineering Contradiction:
Improveflow controlVSAvoidsystem complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The flow control function is extracted and isolated into a single check valve component within the conduit system. This separates the control function from the overall system, allowing simple passive flow management without requiring complex active control mechanisms, motors, or electronic systems.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The check valve provides automatic, passive flow control based on the direction of fluid flow itself, without requiring external power, control systems, or complex mechanisms. The valve self-regulates flow direction purely through the physical properties of the flowing medicinal solution.

Inventive Principle:
Principle #25Self-service

3Measurement precision

If concentration checking requires separate collection conduits or complex setups, then measurement precision is improved, but device complexity and cost increase

Engineering Contradiction:
Improveconcentration measurementVSAvoidmeasurement system complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The concentration measurement function is merged with the existing medicinal solution supply conduit system. The check valve and conduit structure that already exist for solution delivery are utilized for both flow control and concentration sampling purposes, eliminating the need for separate collection conduits or additional measurement infrastructure.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The medicinal solution supply conduit and check valve assembly serve multiple functions: they control the flow of medicinal solution to the cleaning tank and simultaneously provide access for concentration checking. This multi-functionality eliminates redundant components and simplifies the overall system while maintaining measurement capability.

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