Production of cover drain
Hollein, Radek ; Císařová, Michaela (referee) ; Podaný, Kamil (advisor)
Diploma thesis deals with the design of producing the cover drain. The cover serves to catch impurities while draining liquids. The part is made of 1.4301 stainless steel, using 1-mm thick sheet metal. The size of the annual production series is 30,000 units. As an optimal method of production, progressive cutting and shallow drawing were selected in a combined and a one-purpose tool. Technological and design calculations were performed according to which tools were designed. The LENP 100 press was selected considering the total required pressing force. The cost of one piece production was calculated at 18.91 CZK and the production becomes profitable with annual production higher than 19,478 units per year.

The wrist joint for upper limb prosthesis
Hollein, Radek ; Komenda, Lukáš (referee) ; Paloušek, David (advisor)
This bachelor thesis deals with the structural design of the wrist prosthesis allowing positionability and lock and subsequent implementation of a functional prototype. The structural design is made to be innovative. With respect to the research, the range of movement and the number of positions of the locking mechanism are selected to ensure the functionality of the prosthetic wrist. The size of wrist prosthesis is designed for an adult male hand. For the structural design Autodesk Inventor Proffesional 2012 was used. Drawings were prepared using AutoCAD Mechanical 2012. Individual components of the prototype are made of ABS plastic, using rapid prototyping technology, or steel machining blanks.
