The Cranfield/Electrolux Smart Sink – photo from Trespassers by Ed van Hinte and Conny Bakker.
Ten years ago, teams from Cranfield University and Electrolux Industrial Design collaborated on an ‘eco-kitchen’, a family of related concepts for a kitchen of the future. Part of the intention was to demonstrate that eco-design could be a positive spur to innovation, rather than merely an ‘environmental cost-cutting’ exercise. The project is explained in this article from The Journal of Sustainable Product Innovation [PDF] (starting on page 51).
What’s especially interesting from the architectures of control / design for behaviour change perspective is the Smart Sink (above), which, very simply, uses a membrane for the bowl, expanding (treefrog-vocal-sac-like,) as it’s filled, thus making it much more easy to control the amount of water being used – along with some other neat features in the same vein:
The ‘Smart Sink’ is the centre of household water management. A membrane sink expands to minimise water use and a smart tap switches from jet to spray to mist to suit customer needs. A consumption meter and a water-level indicator in the main basin gives feedback on rates and level of water usage. Household grey water is managed visibly by an osmosis purifier and a cyclone filter located in the pedestal, and linked to the household grey water storage.
We’ve looked before at taps (faucets) with built-in water meters, in various forms, but the Smart Sink concept goes beyond this in terms of assisting the user control his or her own water use. Gentle persuasion or guidance rather than external control, but guidance that gives the user helpful feedback. Ten years later: are membrane sinks available? Why not? What else could be done in this line of thinking?
