are easy to assemble and disassemble allow to perform this.
Block-modular design provides for the creation of products based on modules and blocks.

A module is an integral part of a product, consisting mainly of unified or standard elements
for various functional purposes.
A method of designing machines, instruments and other
products from unified and standard parts and assemblies
(from modules) was designed on the basis of unification.

Aggregation is a structurally variable synthesis of
machines, in which the solution of a new problem is provided by
a change in the structure of the machine, namely: the spatial
position of individual modules, their number and nomenclature,
as well as connection methods.
The modular method of designing equipment, i.e. design and layout of various machine

The analysis of the conducted research allows us to draw the following conclusions: to this to the fullest extent.

manufactured independently of each other, are interchangeable in all operational parameters and
connection dimensions. Therefore, they must have an optimal design, optimal quality indicators,
consist of the smallest possible number of parts, and be easily and reliably assembled using
various kinds of connections.
Aggregation allows to assemble a new machine from assembly units that have already
