Solution Overview

Problem

The assembly of sanitary fittings is complicated by hoses that are difficult to connect due to space constraints and the risk of kinking, especially when the hose end is not accessible from the outside, leading to potential resistance and tilting issues during valve insertion.

Innovation Solution

The hose extends between the outlet piece and the valve outside the housing of the sanitary fitting, allowing for easier connection and visual inspection, with a deflection mechanism using a connecting element to route the hose past the valve, avoiding excessive bending and kinking, and remaining accessible for maintenance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Volume of moving object

If the hose is connected inside the housing of the sanitary fitting, then the assembly is compact, but the hose connection becomes difficult and prone to kinking due to space constraints

Engineering Contradiction:
Improvehousing space utilizationVSAvoidhose connection ease
Core Design Contradiction:
Volume of moving objectVSEase of operation

Solution Approach 1:

The hose connection is extracted from the confined interior space of the housing and positioned on the exterior surface. The hose extends from the outlet piece through the housing wall to connect to the valve externally, allowing sufficient space for connection operations and visual inspection while maintaining compact internal housing design.

Inventive Principle:
Principle #2Taking out (Extraction)

2Stability of the object's composition

If the hose is permanently installed inside the housing, then the assembly is compact, but the hose becomes inaccessible for maintenance and inspection

Engineering Contradiction:
Improveassembly compactnessVSAvoidhose accessibility
Core Design Contradiction:
Stability of the object's compositionVSEase of repair

Solution Approach 1:

The hose connection point is extracted from the interior to the exterior of the housing, making the hose accessible for maintenance and inspection while keeping the housing compact. The hose passes through the housing wall to reach the valve externally positioned components.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The housing wall acts as an intermediary structure that the hose passes through, allowing the hose to be both protected within the housing assembly and accessible from the outside for maintenance purposes.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Productivity

If the valve is inserted with pre-connected hoses, then the assembly is complete, but the valve may jam or the hose may kink due to resistance during insertion

Engineering Contradiction:
Improveassembly completenessVSAvoidvalve insertion reliability
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The assembly process is segmented into separate steps: the valve is first inserted into the housing without hoses attached, ensuring smooth insertion without resistance or kinking risks. After the valve is securely positioned, the hoses are then connected to the valve's external connection points, completing the assembly in a reliable sequence.

Inventive Principle:
Principle #1Segmentation

4Volume of moving object

If the hose connection point is inside the housing, then the assembly is compact, but visual inspection during assembly is difficult

Engineering Contradiction:
Improvehousing compactnessVSAvoidconnection inspection difficulty
Core Design Contradiction:
Volume of moving objectVSDifficulty of detecting and measuring

Solution Approach 1:

The hose connection point is extracted from the interior to the exterior of the housing, enabling visual inspection of the connection during assembly and maintenance. The connection is positioned on the outer surface where it can be easily observed and verified for proper installation.

Inventive Principle:
Principle #2Taking out (Extraction)

AI summary

What is proposed according to the invention is that, in a fluidic arrangement (2) which can be mounted inside a sanitary fitting (1), a hose (5) which connects an outlet piece (3) to a valve (4) is to be designed with such a length that the hose (5) projects from an interior (6) which spatially connects the valve (4) to the outlet piece (3). This projecting portion of the hose (5) is fluidically connected to the valve (4) outside the interior (6).
