New Mechanical Platform For Dome Cameras

Sammanfattning: This master thesis report describes a product development process with the aim to create a construction which ensures an easier installation by replacing screws with other alternative assembly methods. The project has been performed at Axis Communications AB, which is the market leading company in network cameras. A previous project called Rocky provided the idea of an excenter lock compressing and holding the camera together, which worked as starting point for one of the sub problems for this thesis. A background study was made to get better understanding of how the installation process works and which different assembly methods occurs in products on the market today. The study showed that screwless assembly methods occurs everywhere and in many different forms, but the most common ones seemed to be snap fits and bayonet solutions. The final concept consists of three main parts, a mounting bracket where excentre locks are pre-assembled, the chassis and the dome which are assembled together without the use of screws. The chassis is mounted on the bracket by a rotating bayonet which provides feedback to know when it is placed correctly. The locks are first closed partially to hold the dome, enabling rotation of it. The locks are then completely closed and keeps the camera compact. The result of this thesis shows that a screwless installation of a dome camera is possible.
