Churn.

Home Ice Cream Maker

Churn is a single serving home ice cream maker that allows an individual to create their own personalized flavored pint of ice cream.

The Problem:

How can the ice cream making process become a more effortless and enjoyable ritual for those who want to make smaller serving sizes?

Research

Market Research:

Existing models of ice cream machines were evaluated to determine the strengths and weaknesses that lie in the current market. The top selling home ice cream makers were of quality build but only made larger family sized amounts. The only “pint-sized” models available appeared flimsy and struggled to effectively churn the ice cream.

User Research:

User needs were gathered through a survey sent to an ice cream maker's Facebook group and interviews with casual users. There were 32 total responses.

Findings:

Major patterns of the user's wants and needs.

Experiment with flavors & customize ingredients
Make easier to clean, smooth texture
Create small ice crystals
Reduce cold feeling in hands

Exploring Functions of Existing Models:

An existing ice cream machine was deconstructed to observe the internal mechanisms.

Ideation

Form exploration was completed through sketches and ¼ scale 3D printed models.

The Design Solution

Churn Form.

A shallower bowl allows for easier scooping and cleaning. Relocating the motor to the base allows for more stability and easier lid handling.

Silicone Handle + Clear Lid

The clear lid provides visibility of the process. A silicone handle grip not only creates a soft touch, but also prevents the hands from touching ice cold temperatures.

Lid Holder and Rotating Bowl

The notch inside of the transparent shell holds the lid and mixing paddle. The bowl interlocks with the base so it can rotate and churn.

How to Use:

Lock frozen bowl with ingredients to the CHURN machine.

Place lid and set timer.

When the timer is done and the ice cream appears thickened, enjoy the frozen treat.
