Cordless Kitchen
12 weeks, 2012, Lund School of industrial design

Cordless kitchen is a stove and a series of kitchen products that propose a new way of heating food and water in the kitchen. With help of heating sensors, it increases safety and convenience, as well as offer the possibility to use less technically complex kitchen appliances in new ways.

Before the 1950’s, almost all food preparation that required heat was done on the stove. Today most kitchens are full of electric appliances with their own individual heating elements, cables and sensors. They offer convenience and safety, but are often not very durable and difficult to repair once broken. In our research we looked into the so called Sliding Mode Observer technology, which enables sensors to measure the temperature of the fluid inside a pot through the surface of the vessel.

Concept
The stove utilises these sensors to give the user more control of the cooking process, such as maintaining a pot of water at boiling temperature or to shut the heat off when the desired temperature is reached. The interface combines gestures that are known from other technical devices today with heat levels and iconography that is familiar from the existing paradigm.

Maintain overview
The aim of the interface is to provide more distinct visual feedback. The abstract indication of the heat levels makes it possible with a quick glance to get reassurance that everything is as it should be.

New possibilities to old beloved objects
The heat sensors also provide new functionality to existing products – such as a traditional kettle. The kettle function turns off the heat when the desired temperature is reached.

Back to basics
To complement the vision of a simple and more sustainable kitchen, we designed 3 robust products; a vacuum coffee maker, a waffle iron and a kettle. Made out of stainless steel and interchangeable wooden handles, they are designed to last.
