What is mechanical design?

Often referred to as engineering design or machine design, mechanical design is the process of designing components, parts, products, and systems that are inherently mechanical in nature. Any type of machinery or any product that has complex parts requires some form of mechanical design. Mechanical design techniques are used to produce objects such as gears, clutches, shafts, and fasteners. 

Engineers who focus on mechanical design are concerned with how various mechanical parts react with each other and their environment. The main aim of the mechanical design process is to produce the most efficient, reliable, and cost-effective method of creating a mechanical system. Mechanical design can be used to create an entirely new product or machine, or it can be used to enhance the features of an existing product or machine.
