Ice Cube Tray Overflow Notches to Prevent Frozen Bridges
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional ice cube trays require individual filling, often resulting in irregularly shaped ice cubes due to overfilling and interconnecting ice formations, which are difficult to remove without breaking the tray.
Innovation Solution
An ice cube tray design featuring overflow notches with apertures that allow simultaneous filling of multiple trays and prevent ice connections by accommodating water expansion, with a twisting mechanism for easy cube release.
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 ice cube uniformity deteriorates due to interconnected ice formations
Solution Approach 1:
The tray is divided into multiple independent cavities, each with its own overflow notch. This segmentation allows water to be distributed to multiple cavities simultaneously while maintaining independent control over each cavity's fill level, preventing interconnected ice formations while enabling efficient simultaneous filling of multiple trays
Solution Approach 2:
The overflow notches enable the tray to self-regulate its fill level automatically. When water is poured into the tray, excess water naturally flows out through the notches, eliminating the need for complex flooding apparatus or manual filling control, thus achieving simple simultaneous filling of multiple trays
2Quantity of substance
If the tray is filled to maximize ice cube volume, then ice cube size is improved, but overfilling occurs causing interconnected ice formations that are difficult to remove
Solution Approach 1:
The overflow notches are positioned at a height that anticipates and prevents the harmful effect of overfilling. By providing a predetermined overflow path before interconnected ice can form, the design proactively eliminates the problem of difficult-to-remove ice cubes while still maximizing ice cube volume within the cavity constraints
3Speed
If water is poured from a distance above the tray to fill it quickly, then filling speed is improved, but splashing increases causing irregular ice cube shapes
Solution Approach 1:
The overflow notches act as an intermediary element that receives and redirects falling water. By positioning the notches to intercept water flow from above, they serve as a mediator that converts high-speed pouring into controlled overflow, maintaining filling speed while preventing splashing that would cause irregular ice cube shapes

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.
