The next important step of the system design cycle or machine design cycle is making the preliminary design and the development of the product. This is not the final design of the product.
After doing the preliminary design and development of the machine the next important step is making the detailed design of the machine or product. This stage of the machine design cycle should not be confused or mixed with the previous stage of making the preliminary design.
Once it has been decided that the project is feasible technically as well as economically, comes the next important step of the system design which is creative design synthesis. The creative design synthesis is the first step of actual machine design and the most challenging and interesting part.
Recognition of a need is the first and the most important step of the machine design or system design, without this first step no further steps of the machine design can be taken. It is the need that gives birth to various other steps of the design.
Stating the specifications and the requirements is the next important step of the system design cycle or machine design cycle. In this step all the requirements and the specifications of the need are studied in full details.
The next important step of the system design or machine design cycle is feasibility study. The main purpose of the feasibility study is to check the possibility of the success or failure of the proposed project both from technical as well as economic point of view.
Whenever the new product or the machine is to be design there is a cycle of the steps that are followed. The sequence of the events in the machine design or system design have been codified Asimow, who is considered to be the father of system design. This sequence is called as system design cycle.
There are some unusual mechanisms which can meet common needs of mechanical engineering problems. These tools help with a range of purposes like generating straight lines, transferring torque between non-coaxial shafts, self centering steering and mechanical punched card readers.
Have you ever wondered what mechanical engineering is all about? I cannot make you a certified mechanical engineer but certainly you can learn a lot about mechanical engineering by reading this Learn from Home series on mechanical engineering.
Four bar linkages are the most basic and most widely used mechanisms for machine design. They provide simple solutions to the complex motion generation problems. These mechanisms are reliable and at the same time easy to manufacture.
