This thesis presents the design process for an electric shutter system. The electric shutter is a vital safety precaution for the measuring device, which the partner company manufactures. The measuring device uses a concentrated light source to measure the number of studied subjects going by the device. Most common application for this measuring device is in industrial exhaust stacks, where the temperatures can rise higher than electronic components can handle. Successful measuring requires a see-through hole into the measuring medium to get reliable results. The shutter unit protects the device by closing the hole, when needed.
Before starting the design process, the desired requirements set for the system and requirements set by the designed operational environment, were stated. The most notable environmental factor affecting the device is temperature. Electrical components have maximum temperature limits for reliable operation. The operation of the electrical shutter on an electrical actuator, which will generate a certain amount of the electricity need. The system also requires an indicator for the unit to enable autonomous operation.
The design process started by studying the target location inside the measuring device in a 3d modelled version. The parts were then modelled using the Autodesk Inventor software. After the models reached a certain point, prototype versions were 3d printed using a 3d printer. Plastic 3d printed parts were used to test the overall functionality of the unit and the design choices.
The goal for the thesis was to design an electrically operated version of the shutter unit, and this goal was achieved after 3 different prototype versions. The chosen prototype version is ready to be tested more thoroughly with correct materials and environment, to reach the commercial version of the unit.
