External Hose Routing for Sanitary Valve Assembly Access
Find Innovative SolutionsGenerate Solutions
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
Engineering 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
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.
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
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.
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.
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
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.
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
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.

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).
