Ice Maker Downspout with Fluted Cavity for Laminar Water Flow
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional ice-making assemblies in refrigerated appliances often experience turbulent water flow, leading to chaotic water surfaces in ice trays, splashing, and poor ice quality, which can cause mechanical issues and ice buildup on the ice maker's motor and bail arm.
Innovation Solution
A downspout design featuring a cavity defined by flutes and lobes that creates a substantially laminar flow of water from the inlet port to the ice tray, minimizing splash and ensuring smooth water distribution into ice cavities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional water delivery is used, then water is delivered to the ice tray, but turbulent flow causes chaotic water surfaces and splashing
Solution Approach 1:
The downspout changes the flow parameters of water by creating a laminar flow regime through its specific geometry (elongated cavity with flutes and lobes). This transforms the turbulent flow from conventional delivery into a controlled laminar flow, eliminating splashing and chaotic surfaces while maintaining reliable water delivery to the ice tray
Solution Approach 2:
The downspout acts as an intermediary component between the water source and the ice tray. It mediates the water flow by providing a controlled pathway with specific internal geometry that transforms the flow characteristics, preventing direct turbulent discharge into the ice tray while ensuring smooth water distribution
2Productivity
If turbulent water flow occurs, then water is delivered to the ice tray, but mechanical issues and ice buildup occur on the motor and bail arm
Solution Approach 1:
The downspout modifies the flow parameters by establishing laminar flow conditions, which prevents the chaotic splashing that causes ice buildup on surrounding components. The elongated cavity design with flutes and lobes ensures water flows smoothly and predictably, maintaining productivity while eliminating harmful ice accumulation on the motor and bail arm
