Safety Equipment for Motorcyclists
Všianský, Michal ; Svítil, Petr (referee) ; Zdařil, Zdeněk (advisor)
In my thesis I looked for a solution to simplify the transfer and storage of motorcycle helmet. This is the helmet for smaller motorcycles for city traffic, where isn ´t often the sufficient space for helmet storage after the motorcycle is left. I choose this topic because the motorcycles are one of my main hobbies and I know how unpleasant is to move in the city, school or work always with the helmet in your hand because you cannot put it into your backpack or to the standard personal cabinets at school cloakrooms or in the factories. The helmet which I made will reduce its volume by folding approximately about 40% and it makes easier the transfer and enables putting into the storage space, cabinet or hand luggage /backpack, bag/ - as I know acc. to my experience the bikers carry with them. The skeleton and the helmet cushioning is divided into four parts /upper, two side and back/ which enable the folding. The cushioning of the side parts will fill the inside space of the upper part by simple folding, then the side skeleton will be inserted to the upper two-case part and in the last – back part, fixed to the rest of the helmet by the hinges, will fold into the helmet – it covers the above mentioned cushioning of the sides and so it protects its damage. The whole will be fixed by the tightening bend which is also used for helmet fixing on the head. In the dismanted status is everything saved by the locks which connect the back and side parts. The helmet skeleton was made of kevlar which compensates the added weight and also keeps the sufficient solidness. Because of double case enabling the saving of the side parts, the solidity and also the safeness are bitter then by using of normal helmet. The helmet shape is created in easy concept and aerodynamic shape. All details, blending and surface extrudation have the reason. In the bottom is the material enlarged because of locks , in the middle part the enlargement is used for breaking of hanging sides and the cleats on the outside enable the cooling and head airing. For the thesis presentation I make the model 1:1 which cannot be fold up. The skeleton is made with the help of 3D printing and after that colour treated. The cushioning milled on CNC machine of extrude polystyren will be refilled by soft foam and covered by the cloth. The shield protecting eyes will be vacuumed of colourless plastic.

Dining Outdoors
Trčková, Jitka ; Buganská, Tamara (referee) ; Zdařil, Zdeněk (advisor)
Feasting which contains plates, cups, cutlery, quilt and canvas bags as a cover. Bags are made for cyclists, pedestrians and easily used for more demanding users with car. Set is designed for 4 people. QUILT, shape is proceed from square, place for feasting is moved from center of quilt to the longest side on edge. Users are closer together and still can see each other in conversation. Place for feasting is highlighted with colored rubber segments which also help balance surface. PLATES are made from two parts - dinner plate and soup plate. Inside the soup plate is space for cutlery storage. CUTLERY is consisted of desert spoon, fokr and knife. All these three parts have a groove which is enabling fix cutlery together. CUPS, shape is proceed from accidence of hole project. There is a small point on the outside which helps to use the cup out of the quilt without capsizing of drink. This point is designed for sticking in the ground. BAGS have classic oblong cut, they are designed for easy use for cyclists (2 pieces). It is consisted also strap for pedestrian. There are two smaller pockets for set of plates and set of cups inside one of the bag.

The Shape Study of a Tractor
Foret, Martin ; Dubjak, Petr (referee) ; Zdařil, Zdeněk (advisor)
Topic: futuristic tractor In my work I focused on the design of heavy tractor plow in the future between 15-20 years. The main aim was to provide a solution that would undertake the issue of adaptation to different working conditions in which the tractor is moving. Adaptivnost was therefore my main goal. Specifically, I focused on balancing the tractor with respect to the driver (cab should ideally be in the middle between the wheels and as low as possible to reduce fluctuations cab drivers are very annoying and negatively affects driving performance on the tractor) . This position is ideal for traveling, but not to work in small spaces and manipulate the front or rear aggregate when the requirements for the best visibility from the cab. Already in my sketches the main idea is evident when the tractor acts as a "compact housing", which change their length and position of the cab as required. For longer rides, such as dragging the machine back on the field, to extend the chassis cab and go down to the lowest position, thus creating an imaginary triangle (between the cabin and wheels), the lower base of the triangle is the longest and therefore the focus is what the lowest. Conversely for handling in a small space tractor chassis to "withdraw" - the smallest turning radius, while the cab driver to go and see better under the wheels, even on the front unit. As for power, and under current trends, it is considered that in the future will be the most efficient diesel-electric propulsion. Compared to existing engines will be smaller Diesel engine running at speed and deliver the ideal energy for the alternator, which converts it into electricity. energy for electric motors that are in each round. It has the advantage as an independent power to each wheel, improving acceleration, etc. As in the past, present and future, and my suggestion is having to deal with the fact that there always will be the engine, its chilling, and various other elements having a size and you can not change too much. With this fact I have worked from the beginning and to seek solutions that would be consistent with my intent. Finally, I chose the principle that the cabin extends hydraulically angle about 45 'forward and change the length distribution of wheel movement is going through the rear chassis rails. Visually, that is very closely linked to functional aspects, it is a clean and easily readable morphology. The whole tractor is distinct lines, which meanders from the front grille, obtahuje cab to her pulled out of the alternator. The aim was to achieve a compact and dynamic shape of the bonnet. The front lights are designed so that their size and location of the suit while riding on public roads, but also to the need for oversizing greater exposure while working in the field. This helps to light in the cab roof and wings, which enable even the correct estimate of the size and contour of the tractor for oncoming cars. For the same reason, get out of shape fenders and turn signals, which can thus be seen from all angles. The tanks are fitted on the sides of the cab chassis with a total 280 l frame cabin has a triangular profile that corresponds with the previously mentioned strong lines on the hood and headlights on the wings. It is designed to be not only comfortable but also getting a driver and still underrated sufficient space for the driver's legs stretch during long rides.
