Ice Well Diverter Wedge for Crushing Irregular Ice Cubes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional ice crushing assemblies in refrigerators struggle to crush smaller or irregularly shaped ice cubes due to gaps between rotating blades and the ice container perimeter, allowing these cubes to pass uncrushed.
Innovation Solution
Incorporating a diverter wedge near the fixed crusher blades to redirect ice cubes toward the rotating crusher blades, ensuring all sizes and shapes are crushed, regardless of geometry.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional fixed crushing blades and rotating crushing blades are used, then the crushing assembly works for standard crescent-shaped ice cubes, but smaller or irregularly shaped ice cubes can pass through the gaps between the rotating blades and container perimeter uncrushed
Solution Approach 1:
A diverter wedge is introduced as an intermediary component between the ice cubes and the crushing blades. This wedge redirects ice cubes that would otherwise escape through gaps into the crushing zone, ensuring all ice cubes are crushed regardless of size or shape variations.
Solution Approach 2:
The crushing assembly is segmented into multiple functional zones: a diverter wedge for redirecting ice, fixed crushing blades for initial contact, and rotating crushing blades for final crushing. This segmentation allows each component to address specific aspects of the crushing problem, improving overall reliability.
2Reliability
If the rotating crushing blades are positioned to cover the entire perimeter, then all ice cubes would be crushed, but the device complexity and manufacturing difficulty increase
Solution Approach 1:
Rather than extending rotating blades to the full perimeter (which would increase complexity), a simpler diverter wedge is introduced as a mediator. This wedge passively redirects ice into the existing blade coverage area, achieving reliable crushing without requiring more complex blade arrangements.
Solution Approach 2:
The diverter wedge provides a simple, partial solution by redirecting only the ice cubes that would escape, rather than redesigning the entire blade system to cover all possible ice cube trajectories. This maintains simplicity while improving reliability.
3Reliability
If the rotating crushing blades extend to the outer perimeter of the ice container, then no ice cubes can escape, but the manufacturing precision requirements and device complexity increase
Solution Approach 1:
The diverter wedge serves as a tolerance-compensating intermediary that passively redirects ice cubes without requiring precise positioning relative to the container perimeter. This eliminates the need for high manufacturing precision in blade-to-container alignment while maintaining reliable crushing.
Solution Approach 2:
The diverter wedge automatically redirects ice cubes based on their natural trajectory without requiring active control or precise positioning systems. The component self-adjusts to different ice cube sizes and shapes, reducing manufacturing precision requirements.

AI summary
A refrigerator is provided including an ice making assembly. The ice making assembly includes a storage container that has a discharge zone including a crushing assembly for selectively crushing formed ice before dispensing the ice through the dispenser of the refrigerator. The crushing assembly includes both rotating and fixed crushing blades, and including crushing teeth for crushing the formed ice cubes therebetween. A diverter wedge may be positioned at or formed integrally with the fixed crushing blades such that the diverter wedge closes any gap between the rotating blades and the wall of the discharge zone. The diverter wedge can include a sloped portion to move any smaller or differently-shaped cubes from the outer edge of the discharge zone to between the crushing blades such that it is ensured that the cubes are crushed before being dispensed.
