Inventors have enough to face with just coming up with an idea that has not only been developed but creating one that has an appeal to its customers from what it does. Once an Inventor reaches this point it's time for him or her to move onto the patent process which is a whole ordeal itself. First they must research their invention to see if anyone else has something similar in nature and functionality. This is called a "Patent Search" and several invention companies provide these services to the Inventor. If they get the heads up the next step in the patent process is to provide patent drawings. This can be done by a professional drafting service and many can be found online. Before a prototype can be made first the Inventor must have a CAD file created. As before these CAD Designers can be found online and produce a computer file which can be read by plastic injection, and CNC machines. These are the two most common way of manufacturing today.
Patent drawings are the drawings that must be submitted along with all the information describing an invention and its functionality. These patent drawings are very important due to the fact they help the patent office understand the inventions look, functionality, and overall appearance. Without these patent drawings it would be hard for the specialist at the patent office to fully understand the Inventors Invention in full. These drawings can be considered a type of blueprint more or less and can be created at most invention assistant services. It's always a good idea to try and use your Invention Designer as the one who performs your patent drawings so that way you will be able to save time and money throughout your invention venture.
CAD designers are the new drafting specialist of today's world. These designers use special CAD software which enables them to produce 2D and 3D CAD models which incorporate all the necessary information to have prototypes and more made. CAD or Computer Aided Design is just an overall term which can be used with many different specialties. Don't think just any CAD designer will be able to perform the designs necessary for an invention design. Most CAD services only specialize in Architecture, Mechanical, Civil, Electrical, or other fields of design. To find a invention design service who can provide invention and prototype design your best bet is to search online.
Once the Inventor has a CAD file of their invention they can move on to having a prototype made. This process is usually pretty quick and can be done within a day or two of time. Once the Inventor has made their prototype they will have a physical model which they can hold in their hand, present to investors, or use alongside with the information in their patent. The prototype can be made before the patent is done and helps secure the rightful Inventor to Invention. There are companies which can be found online which assist Inventors with all the processes named above, and in most cases will provide a discounted price if you get all the work done there.
