The development of the device design involves the development of the external and internal geometry of the device case, on the basis of which the body parts are built, fasteners and latches are designed, and a theoretical calculation of loads, etc. is made. The result of design development is design documentation, which can be design and working. The development of project documentation is needed for the manufacture of a prototype and production, and working documentation for the launch of mass production.

At this stage, the main requirements and restrictions for the development of the device design are determined. Such constraints and requirements can be such things as materials of manufacture of structural elements, production methods, quality parameters and methods for implementing mechanical components of a structure, etc.
Initially, the design engineer builds 3D models of all the components that will be used in the device. Next, the engineer converts the developed design of the device into body parts and designs all mechanical components (latches, fasteners, etc.). For mechanical devices of the structure, load calculations are performed.
Registration of design documentation is the creation of a set of drawings that are necessary for the production of a device design. The design documentation of the device is prepared in accordance with GOST or ISO standards. Depending on the stage of development, design documentation can be drawn up in two forms: project design documentation or working design documentation.
