Final Entia packaging: foam cradle holding the Liberty analyser inside the box

Overview

I redesigned the shipping packaging for Entia's Liberty analyser, a medical device for at-home blood monitoring. I owned the whole project, from first sketches to a prototype ready to manufacture. The final design went into production and now ships to Entia's customers.

Brief

The Liberty analyser is a medical device sent to people's homes for at-home blood monitoring, and many of its users are elderly. The brief was to make the packaging smaller, protect the device better in transit, and make it easier to handle and unpack.

Process

The original packaging: a large taped cardboard box — Original packaging

The original packaging was far too large and took up too much space. Because it couldn't be reused, it cost Entia £100 every time they used it, and both material and shipping costs were high.

I sketched initial designs to explore different ways to arrange the box.

I worked out the layout of the contents before building the prototype.

Prototype accessories layer — Accessories layer

Prototype foam layer with cut-out — Foam layer

Prototype with the analyser seated — Analyser seated

I built the first prototype from cardboard and foam, the same materials the real box would use. I presented it to the CEO and engineers, the CEO chose to go ahead with the design, and the final box was built.

Outcome

The final design takes up 60% less space than the old packaging. Based on stakeholder feedback, it improved the user experience about three times. Entia chose it for production, and it has packaged devices shipped to customers since June 2026.
