This is a two part article that's written with the novice or beginner designer/inventor in mind.
The intent of this first article is to hopefully guide you through some of the various minefields that you'll encounter, and to also look at the major challenges that any design has to face – from conceptualization to the realistic possibility of your idea being put into production.

While it is easy to find rich, interesting analyses on the way finance companies, law offices and software labs’ inner processes are conducted, little is known about the insides of factories, industrial companies or R&D departments in the mechanical engineering sector. At MDF, we are eager to initiate the public and future mechanical engineers into our domain and give a clearer image of what goes on within our offices.

We spoke previously about the importance of making a CAD model more FEA friendly. A mechanical design engineer should get used to running multiple iterations of a FE analysis, making small modifications to the CAD model for each iteration. To make this iterative process much easier and faster, it is a good idea for the engineer to be aware which of the critical dimensions must be fixed, and which can be modified.

We’ve previously spoken about the concepts of accuracy and precision and how they play a key role in determining the error range in mechanical engineering calculations. The main recommendations were to use the most specific input data possible and to note the accuracy, significant figures and precision used in the input data.
When dealing with functions and equations, such operations can prove exhausting and pricey to perform; for a

For most people, Nicholas Tesla is known for his work in electromagnetism and the unit given his name. For a smaller portion of the public, he is known for his benevolent, full, and rich life. Father of electricity and of several other important inventions, he was a man of many skills who famously contributed to many innovative technologies without care for fame or riches. Many have benefited from Tesla’s work thanks to his open, indiscriminate

There are many options out there when it comes to 3D printers, from the hobbyist level all the way to entry-level professional models. A variety of printers offer options ranging from heated build beds to proprietary super deluxe software. It can be hard to filter through the jargon and figure out what you actually need for your application. Because of this, it can be very easy to get carried away and spend a lot more than you should on

We deal with numbers in every aspect of life. In mechanics, understanding the more obscure concepts and definitions can be critical to our designs. Most people understand that there are two kinds of numbers:
1) Exact numbers: You could safely state there is 1 balloon or 6 eggs in the fridge.
2) Inexact numbers: This could refer to rounded decimals.
Physics has proven however that all quantities are inexact, no quantity

Design optimization – probably one of the phrases burned into any mechanical designers psyche... But what does it actually mean? The mainstream view, in my opinion, is to create a design that achieves more, for less money, and with faster production times. You can also throw into that mix things such as decreased tool wear, less waste material, savings in packaging through components that tessellate and countless others.

The bioprinting sector has taken a very large leap forward. The Drexel Biofabrication lab, led by Wei Sun, PhD,, has just printed its first living cancer cells. Keep in mind though this is not the first time someone has printed living cells.
Organovo, a bio printing company, has already been printing liver tissues and made the first commercially available bioprinter, NovoGen MMX. This printer works by filling one syringe with thousands

A technology that is often overlooked as a design option is the heat pipe. Although it is widely used by many industries it is sometimes considered by the uninitiated to be a device that is difficult to design into a system. This is incorrect. Many devices, including most of today's computers, use heat pipes successfully to cool processors or other components that need high conductivity path from the chip to a remote heat sink and fan.

Human innovations are often inspired by, and at times copied from, the existing designs of nature. Human flight is one example where man adapted one of nature’s existing methods and used it in his own technology. While the aircraft and aerospace industries have improved the performance and perfected the designs of their flying machines, they have never strayed far from the original bird-like design.
