Dishwasher Inlet Valve Mounting for Kink-Free Hose Routing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional domestic dishwashers face issues with transport and installation problems due to horizontal inlet hose alignment, which also makes it difficult to protect against leaked water effectively.
Innovation Solution
A dishwasher design featuring a hose guide that aligns the inlet hose obliquely downward, with a support part that includes an externally open locking holder and a collection surface to secure the inlet valve and collect any leaked water efficiently, reducing the risk of kinking and leakage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the inlet hose is aligned horizontally in the region of the inlet valve, then the hose can be installed at low height, but it is prone to kinking and progressive damage
Solution Approach 1:
The inlet hose alignment is changed from horizontal (2D plane) to oblique downward (3D spatial arrangement), directing the hose at an angle greater than 0 degrees relative to the horizontal plane. This dimensional change eliminates kinking while maintaining low installation height, as the hose now has a vertical component to its routing.
2Reliability
If the inlet hose is aligned upward in the region of the inlet valve, then the hose can discharge continuously toward the valve, but it increases transport and installation complexity
Solution Approach 1:
Instead of aligning the inlet hose upward toward the valve as in conventional designs, the hose is aligned obliquely downward away from the valve. This inverted approach achieves continuous discharge functionality while simplifying the hose routing and reducing transport and installation complexity.
3Ease of manufacture
If the inlet valve is secured in a conventional manner, then assembly is simple, but leaked water cannot be effectively collected and protected against
Solution Approach 1:
The support part combines multiple functions into a single integrated component: it secures the inlet valve through the locking holder while simultaneously providing a collection surface for leaked water. This merging of securing and collection functions maintains assembly simplicity while adding effective leak protection capability.
4Volume of moving object
If the support part depth is reduced, then the overall device size is minimized, but the stability and strength of the locking structure may be compromised
Solution Approach 1:
The support part is formed as an integrated composite structure combining the locking holder and collection surface into a single molded component. This composite design achieves high structural strength and stability despite reduced depth, as the integrated geometry provides inherent structural reinforcement that separate components would require.

AI summary
A dishwasher includes a wash container for items to be washed and configured to conduct at least water during operation, and a fluid line system having an inlet valve defined by a center line and configured for direct or indirect connection of a water inlet line from a water supply network. Disposed below the wash container is a base support having an outer wall provided with a cutout. The inlet valve is secured by a support part which is lockable in the cutout and has at least one externally open locking holder, into which the inlet valve is lockable and secured therein non-movably in an axial direction. The externally open locking holder is aligned in such a manner that the center line of an inlet of the inlet valve runs at an angle between >0° and <90° in relation to a lower face of the base support.
