Embedded Automatic soap dosing with 3+ tanks in washing Machine

The Project involved working closely with engineers from Rold srl, developing the concept of Embedded Automatic Soap Dosing for washing Machine. We as a team of four used the tools and Knowledge ( Functional modelling, Triz theory, Su-field model, Contradiction model, Patent search techniques to name a few) to come up with concept with following features, Used single actuator for pumping and dosing the liquid detergents for 3+tanks, No mixing of detergent liquids in the system, Compliance with dimensions provided, Accurate Dosing, Possibility of extending the system to more tanks with increasing dimension. 

Affordable Magnetic door lock system for home appliances

The entrusted issue consisted in replacing the hook equipping the current closing systems of washing machines, which use 220V solenoids, with an alternative device able to operate at low voltage. A complex demand, since there is the need of both supplying a suitable closing force and of permitting a simple shift from the closure state to the locking one of the door itself. To attain this target, the design turned to the use of permanent magnets and in the specific case of a particular typology of magnets, called Polymagnets. These magnets, instead of presenting a single pole per surface, show a multitude of points, each with a distinct north/south orientation. A specific design of magnets allows achieving a specific behavior between the two elements. In our concept we have used a subsection of polymagnets, called align polymagnets. These have the shape of metal disks that, once aligned, feature a different attraction force depending on their mutual relative rotation (0 closure-low force, 20 locking-high force). An electric 12-volt motor sets in rotation a worm screw/gear system that, hinged to the magnet, allows the passage from the closure state to the door-locking one and vice versa.
