This project aims to redesign the classical moulinex grinder. The product is thought to grind both: coffee and spices. The principal feature implemented are the adjustable bowl, in fact, according to the quantity of beans needed is possible to regulate the space of the container.

This feature with a better extractable blade, help the user to obtain a better, homogeneous, powder.

The product is thought to charge e-scooters used for sharing services like mimoto and ecooltra.

It is composed of two main volumes (the head and the body): The Battery and the Charging Pad. The head mainly contain a linear actuator connected to a square pad which will charge the mimoto. The recharger will get in contact with the scooter and will richarge it thanks some pins located close to the mimoto plate .

How it works

My thesis investigates a new innovative way of cleaning teeth and providing mouth hygiene with ultrasonic technology.

Thanks to an extensive research on conventional brushing, flossing tools, techniques, technologies, materials, users habits, etc., we conclude that ultrasound has a great potential application in the odontoiatric field, specifically in cleaning teeth and biofilm crumble from the most remote areas of our teeth apparatus. After deciding the cleaning technique, a product has been developed with specific boundary conditions: being independent from the dexterity of the user and being adaptable to different archs apparatus. Consequently, a new experience of taking care of the oral health has been settle and, at the end, strongly remark the appeal of the product. To conclude, material investigation and shape optimization of some functional components which have an active behave in the user experience performance has been part of the engineering process.

This report strives to analyze the forces present on a new spring baseplate of a skateboard, which will give lightness and dumping performance. Finite Element analysis will be conducted on this piece using a number of forces and constraint representative of a skateboard ridden normally (500N), on one set of wheels, as well as an impact of 2000 N. We will define which is the safe thickness spring plate to use for normal and impact static load, which parts are mostly stressed during the carving, and which shape will perform better in real specific case.

To model shell structures, the quadratic triangular element STRI65 were used.

The STRI65 elements is a 6 node triangular thin shell with thickness equals to 1,5 mm for the sides, and 0,5 mm where holes or geometry distortions are presents.

Each node is described by 5 degrees :three translations and two in-plane rotations (i.e., no rotations about the shell normal)(2° order shape deformation)

D. Prototype

05.

This project aims to reproduce with a CNC machine an old sufboard Stewart thanks to the Reverse Engineering technics. There are different steps that need to be respect.

For instance, the 3D scanning phase needs to be done in specific conditions acccording to the environment and the item surface. The software tool used to archieve the final result are Geomegic and Solidworks. To Conclude, the final result has been discussed and overlapped to the initial model.

Data Acquisition Point clouds are created using 3D scanning equipment that collects a large number of points from the objects surface and records their location in space (X,Y,Z). This file has been cleaned from some error points due to reflective parts.

Mesh Mesh files are most commonly used in manufacturing methods such as 3D printing, rapid prototyping and computer aided manufacture.They can also be used for inspection, measurement and reverse engineering.

A Mesh file can be generated from a point cloud file, created by 3D scanning eqtuipment. This process does requires some post processing of the scan data to optimize it for use with an .stl. Additional post processing actions can be performed on mesh files too, such as smoothing, de-featuring, filling holes etc. Mesh files can also be created by converting CAD models.

This allows for the creation of hybrid models, where some features have been created from scan data and some by more conventional CAD.

Paramatric File

A parametric CAD model is what most people have ecperienced using CAD sofware. This model type is constructed manually , as you would typically expect using sketches, plasnes, extrudes, cuts, lofts and al other funcitons in a cad package.

This file has been exported in 2 main type format file i.e. .IGES and .STEP.

Matching Process Result

The matching process is usefull to verify how much the difference there is between the scanned model and the rebuilted model. As we can see, the green part has a deviation of 0,001 and -0,001 millimeter. The green part has an error range of -1 to 1 micron in the 92 % of the surfboard. The tail of the surfboard was ruined so, more difficoult to reshape. This because the 3D scanner had some reflaction trubles. The blue part doesn’t match the surfboard because is present the padon the real model. The rebuilt model has been accepted in the serial process.
