Solution Overview

Problem

In healthcare environments, connecting water guiding tubes to sanitary fittings mounted in basins with rear-accessible hollow cavities poses a challenge due to limited space and the need for bending tubes, complicating the mounting process.

Innovation Solution

An adapter with a main body featuring inlet and outlet openings arranged laterally and upperly, respectively, with a connection mechanism allowing mechanical fastening to the sanitary fitting, enabling 90-degree water stream diversion without bending tubes, and utilizing antibacterial copper-based alloy surfaces and nipple elements for secure attachment.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If water guiding tubes are directly connected to sanitary fitting in the hollow cavity, then connection is achieved, but the tubes need to be bent which complicates the mounting process

Engineering Contradiction:
Improvemounting processVSAvoidtube bending requirement
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The adapter acts as an intermediary component between the water guiding tubes and the sanitary fitting. It provides threaded connection openings that accept the tubes without requiring bending, while its outlet connects to the sanitary fitting tail. This mediator eliminates the need for tube bending operations during mounting.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The connection system is segmented into distinct functional components: the adapter body with inlet openings for tubes, water guiding channels for flow diversion, and outlet openings for sanitary fitting connection. This segmentation allows each component to be optimized independently and simplifies the overall mounting process.

Inventive Principle:
Principle #1Segmentation

2Area of stationary object

If the hollow cavity is accessed from the rear of the basin, then connection can be made, but the space available is limited

Engineering Contradiction:
Improveconnection spaceVSAvoidmounting accessibility
Core Design Contradiction:
Area of stationary objectVSEase of operation

Solution Approach 1:

The adapter utilizes the vertical dimension within the limited hollow cavity space by positioning its inlet openings on the lateral side and outlet openings on the upper side. This three-dimensional arrangement allows water flow diversion within the confined space without requiring extensive horizontal clearance, making rear-accessible installation feasible.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

3Adaptability or versatility

If water streams are diverted by 90 degrees, then connection flexibility is improved, but the space required for diversion increases

Engineering Contradiction:
Improveconnection flexibilityVSAvoiddiversion space
Core Design Contradiction:
Adaptability or versatilityVSVolume of stationary object

Solution Approach 1:

The water guiding channels within the adapter body provide curved pathways that divert water streams by approximately 90 degrees. The curved channel design achieves the necessary flow direction change within a compact volume, avoiding the need for large-radius bends that would consume excessive space in the hollow cavity.

Inventive Principle:
Principle #14Spheroidality (Curvature)
