The Problem
Panasonic devised a 1 week design challenge to conceptualise a product that ”reduces waste”.

The Solution
Onepan reduces wasted time, food and water in the kitchen by empowering users to cook precisely the right amount of food based on their needs.
Ethnographic Research
I conducted several observation sessions to gain an through understanding of the problem. Although food preparation methods varied widely, inaccurate portion control featured as a recurring issue amongst participants.
Developing the UI
Keeping the user experience simple was critical. I combined physical and digital user testing to validate and refine the interface.
The Technology
Onepan uses a heat resistant HT201 force sensitive resistor to measure the mass of food within the pan. This reading is then relayed to users via the intuitive LED/LCD interface. This allows users to quickly gauge how much food is in the pan, relative to their desired portion size.
Rapid Prototyping
The interface needed to be compact yet accommodate the needs of a wide range of percentiles.
Effortless Portion Control
Onepan effortlessly enables users to precisely control their portion sizes by seamlessly integrating mass measurement.
Modularity
In addition to reducing food waste, the removable handle allows users to save space in the dishwasher. To remove the handle, the user simply pinches the buttons on either side and twists. In turn, this releases the pan. The thermally conductive non-stick container can also be replaced if damaged.
