Third Year Studio


12 weeks



This product must provide a safe and effective method for heating and sterilizing a baby bottle on the go.

Key Issues

Through an analysis of existing products,  the common problems were identified

User Testing

Different handle designs were tested to determine the best interaction with the product

The major interaction with the product, removing and replacing the lid on the base of the warmer, was tested by ten design students.

To simulate a real life scenario, participants were asked to hold a weighted baby doll. Participants were then instructed to remove the lid, insert the baby bottle into the base, and place the lid back on top. They repeated this for all three lids both standing and sitting because the product is intended to be used while on the go.
