Dishwasher Spray Assembly Valve for Selective Wash Fluid Routing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dishwasher appliances inefficiently distribute wash fluid between spray assemblies, as the fixed ratio of fluid flow can be wasteful when one spray assembly is not needed.
Innovation Solution
A dishwasher appliance with a manually actuated valve that selectively directs wash fluid to a secondary spray assembly, allowing for adjustable fluid flow distribution based on user needs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If wash fluid is distributed to multiple spray assemblies at a fixed ratio, then both spray assemblies can operate simultaneously, but wash fluid is wasted when one spray assembly is not needed
Solution Approach 1:
The supply conduit is segmented into multiple separate conduits, each leading to a different spray assembly. This allows independent control of wash fluid flow to each spray assembly through individual valves, enabling selective operation based on actual cleaning needs and preventing waste when certain spray assemblies are not required.
2Productivity
If a manually actuated valve is added to selectively direct wash fluid, then fluid flow efficiency is improved, but device complexity increases
Solution Approach 1:
The valve system is designed to be dynamically adjustable by the user, allowing real-time modification of wash fluid distribution based on the specific cleaning task. The manual actuation mechanism provides simple, intuitive control that adapts the system configuration during operation without requiring complex automated control systems.
