Solution Overview

Problem

Existing soap dispensers are cumbersome to maintain due to the need to replace the soap hose, which requires routing it through the pump unit and sanitary fitting, making it difficult to swap out the soap reservoir without significant effort.

Innovation Solution

A soap dispenser design featuring a detachable pump unit with a flexible guide line that allows for easy alignment and attachment, enabling the soap hose to be inserted and routed to the sanitary fitting without tools, and a fastening device that allows the pump unit to be removed and reattached without tools, simplifying the replacement process.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the soap hose is routed through the pump unit and sanitary fitting body, then the soap can be conveyed from the storage container to the outlet, but the replacement of the soap reservoir becomes cumbersome and time-consuming

Engineering Contradiction:
Improvesoap conveyance reliabilityVSAvoidtime for replacing soap reservoir
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The pump unit is segmented from the sanitary fitting body, allowing the pump unit to be detached and repositioned independently. This segmentation enables the soap hose to be routed more easily during replacement while maintaining the connection between the pump unit and sanitary fitting through the flexible guide line.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

A flexible guide line is introduced as an intermediary element between the pump unit and the sanitary fitting body. This flexible guide line allows the soap hose to be guided through the pump unit and out to the sanitary fitting during replacement, facilitating easier maintenance while maintaining reliable soap conveyance.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Stability of the object's composition

If the pump unit is permanently installed underneath the washbasin, then the structure is stable, but the soap reservoir replacement becomes difficult due to limited accessibility

Engineering Contradiction:
Improvestructural stabilityVSAvoidease of soap reservoir replacement
Core Design Contradiction:
Stability of the object's compositionVSEase of operation

Solution Approach 1:

The pump unit transitions from a permanently fixed installation to a dynamically repositionable configuration. The fastening device allows the pump unit to be attached and detached easily, enabling it to be moved to positions with better accessibility for soap reservoir replacement while maintaining stable installation when attached.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The fastening device is separated from the sanitary fitting body, allowing the pump unit to be independently attached and detached. This segmentation provides stable installation when the pump unit is attached while enabling easy removal and repositioning for maintenance operations.

Inventive Principle:
Principle #1Segmentation

3Reliability

If the soap hose must be inserted through the pump unit during replacement, then the connection is secure, but the replacement process requires significant effort and complexity

Engineering Contradiction:
Improvehose connection reliabilityVSAvoidcomplexity of replacement process
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The flexible guide line acts as an intermediary that simplifies the hose insertion process. It guides the soap hose from the storage container through the pump unit and to the sanitary fitting in a controlled manner, reducing the complexity of the replacement process while ensuring reliable connections.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The pump unit can be pre-positioned and the flexible guide line can be pre-routed before the actual soap reservoir replacement. This preliminary arrangement of components simplifies the insertion of the new soap hose through the pump unit, reducing the overall complexity of the replacement process.

Inventive Principle:
Principle #10Preliminary action
