Piavo
Ultrasonic Sink
The
Challenge.
Revolutionize the preparation of food and cooking experience.
This project was a partnership between two university innovation hubs: Porto Design Factory and Warsaw University of Technology and a Portuguese stainless steel company, Silampos, that produces pots and pans.
The
Outcome.
A fast, efficient, and precise cleaning system that will clean your daily cookware effortlessly in 6 to 12 minutes through an ultrasonic and water jets system that can be attached to any stainless steel sink.

Understanding
the Problem.
Throughout a few months of research, surveys,
interviews, and user experiments. It was noticed one of the biggest pains and demotivators for many people is cleaning after cooking/eating and even for some people it removes the desire to cook since they have to clean afterwards.
The team understood that cooking and preparing food depends on the person on each personality and it is a trial and error experience. Once you know you try and add new flavors and techniques.
Cleaning is the most painful step in the cooking process!
How might we improve the cleaning process for young people who live in small places so it adapts to their modern lifestyle changes?
The Solution.
Piavo is a fast, efficient, and precise cleaning system that will clean your daily cookware effortlessly in
6 to 12 minutes through ultrasonic and water jets system that can be attached to any stainless steel sink.
How does it work?
1. Filling
Before the cleaning begins it is necessary to fill the inox sink/container, with hot water that comes from the direct plumbing, to submerge all the cookware for the ultrasounds to work.
2. Ultrasonic
Cleaning
Ultrasound is an oscillating sound pressure wave with a frequency greater than the limits of the human hearing range. But even though we can't hear it, those sound waves are very powerful and work through vibrations.
​
This is possible through an input and output energy conversion system that turns electrical energy into sound.
Specific frequency ultrasound waves in the water trigger a process called, cavitation, where there are sensors of output, called transducers, that receive a frequency signal, and with this, they vibrate and create oscillation in water and form sound waves on the water that form high-pressure bubbles.
These bubbles collide with the “dirt” of the surface that is inside the water and make it detached and dissipate on the water in a very short amount of time.
3. Final
Rinse
Final rinsing concludes the cleaning to remove difficult dirt/oil of the cookware with clean hot water jets.
4.Next Cycle
After the cycle is over, to not waste water, firstly we would filter the water through inox sand and carbon filters.
The filtered water goes into a deposit that will be re-heated and that same water can be used up to 5 cycles in total.
