JungDesign
Food safety product system / From 2000, developed over several years

The Egg Splitter System (TESS)

A system developed to reduce salmonella risk by allowing eggs to move through restaurant handling and processing without staff touching the shell.

Proof point

The project sits between object design and operational design: a tool, a process and a risk-control idea.

01

What had to be solved

In high-volume food service, egg-shell contamination risk is amplified by repetition. McDonald’s Australia alone handled tens of millions of eggs per year.

02

What JungDesign did

David developed a system enabling eggs to be delivered to and processed through a restaurant without direct shell contact by staff.

03

Why it mattered

A product-system response to operational food-safety risk, developed with major commercial users over a multi-year period.

Connection to the paintings

This kind of work explains the structure in David’s paintings: the clear edge, the controlled crop, the object treated seriously, and the confidence that comes from decades of making ideas survive contact with real-world constraints.
