Some people believe that behind every great idea there must be a product. Mechanical engineering design is crucial when developing a product, but what use is an amazing and creative idea if you can't make anything out of it? The process of designing and building a mechanical prototype can be very complex.
You need to find the right materials for your project, create parts that fit together in the right way, make everything work together seamlessly - which can be difficult if you are trying something new or working to a tight schedule.
And it doesn't stop there: once you've established what will actually work as designed, along comes the production phase, where all these individual elements are transformed into a single functional unit ready for sale!
