Ice Cube Tray Overflow Notch Design to Prevent Frozen Interconnections
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional ice cube trays require individual filling, often resulting in irregularly shaped and interconnected ice cubes due to water expansion during freezing, making it difficult to remove cubes without breaking connections.
Innovation Solution
An ice cube tray design featuring overflow notches with apertures in the top edge of each cavity, allowing for simultaneous filling of multiple trays and preventing frozen connections between cubes by accommodating water expansion, while also facilitating easy ejection of ice cubes through a twisting motion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple trays are filled simultaneously using a flooding apparatus, then filling efficiency is improved, but the device complexity increases and interconnected ice cubes still form
Solution Approach 1:
The tray is segmented into multiple independent cavities, each with its own overflow notch system. This segmentation allows water to be distributed to multiple cavities simultaneously while maintaining independent control over each cavity's water level, preventing interconnections while enabling efficient simultaneous filling.
Solution Approach 2:
The overflow notches provide a self-regulating mechanism where excess water automatically drains from each cavity when the ice expands during freezing. This self-service feature eliminates the need for complex external control systems, allowing simultaneous filling of multiple trays without increasing device complexity.
2Manufacturing precision
If the tray is filled to accommodate water expansion, then uniform ice cubes are formed, but interconnected ice cubes form between cavities
Solution Approach 1:
The harmful effect of water expansion is extracted and managed by providing dedicated overflow notches in each cavity. These notches allow the expanded ice to displace excess water without forming connections with adjacent cavities, thereby maintaining manufacturing precision while eliminating the harmful interconnection effect.
Solution Approach 2:
Each cavity is equipped with its own overflow notch positioned at a specific depth, creating local quality control for water level management. This localized approach ensures that each cavity independently manages its water level to accommodate expansion without affecting neighboring cavities, preventing interconnections while maintaining uniform ice cube formation.
3Manufacturing precision
If the tray is tilted to redistribute water during filling, then water distribution is improved, but the operation complexity and time increase
Solution Approach 1:
The overflow notches provide automatic water level regulation without requiring manual tilting or redistribution operations. When water is poured into the tray, it naturally flows to fill cavities, and the overflow notches self-regulate the water level, maintaining uniform distribution while keeping the operation simple and straightforward.
4Object-generated harmful factors
If overflow notches are added to each cavity, then interconnected ice is prevented, but the device complexity increases
Solution Approach 1:
The overflow notches are integrated into the thin partition walls between cavities, utilizing the existing tray structure. This integration approach adds minimal structural complexity while effectively preventing interconnected ice formation, as the notches are simply openings in the partition walls rather than separate components.

AI summary
A tray for forming frozen solids such as ice cubes is described. The tray includes a plurality of cavities, each cavity having a base, sidewalls, and a top edge. An overflow notch including an aperture is located in the top edge of each cavity. The overflow notch is of a sufficient depth such that when the tray is filled with liquid up to the level of the overflow notch, and then placed in a freezer to form cubes of frozen solids, connections of frozen solid are not formed between the cubes, even if the liquid expands when it freezes.
