One of the issues inventors face is that they can typically see their invention in their mind just as they believe it will be when finished. Unfortunately, almost everyone else only sees what you can show them.  They don’t envision all the future changes the inventor sees.  The result is that models and prototypes are important to entice investors to invests and companies to form partnerships. 

INVENTION ILLUSTRATIONS BEFORE PROTOTYPES

If you are trying to get financial help in producing prototypes, it is often worthwhile to do an invention illustration so people can understand your idea,

We are visual people with a better understanding of what we see rather than what we read or hear about. If you have a brilliant invention idea, you may need to convey its usefulness before the prototype is developed. That means you’ll need some kind of imagery of what it may look like and what it does. Product illustration is the visualization of your idea, a conceptual representation. It is used to show and tell before you have the actual product to demonstrate. Eventually product photography will take its place, but for now illustration will do a great job simplifying the subject, making it easily understood.

The best time for product illustration is right away when you need a visual. You couldn’t send a product developer a flyer full of only letters and words. That would do no justice to the idea. An illustration will generate almost as much interest as a photo, so put it on a brochure to send out if you want to create some buzz early on or if you want to test the waters to see what kind of attention your idea generates. It could even be the drawing that you show to an engineer to help him or her decide on how to produce the prototype. They have to base their calculations off of something.

Different Options for Illustrations

There are multiple ways to illustrate a product: either with a computer or traditionally by hand. Either way works fine.

Computer Illustration

Computer illustration is the most common and can sometimes be quicker with a more realistic look. There are a few different illustration software programs that are the standard in use. Some work strictly in 3 dimensions while others act as more precise drawing tools. They can provide all sorts of textures and effects to make the product look alive.

Rendering By Hand

Rendering by hand can be done with pencils, paints, pen and ink or any art materials. The choice really depends on the product, like a soft and fuzzy stuffed animal, which could get that look through colored chalks. Charcoal will give an aged, hard look while watercolors would create more delicate artwork. Before anything, you’ll need to decide on your product’s branding, or its personality, that you want to convey to your audience. That will help determine the illustration style.

Multiple Viewing Angles

Most likely you’ll need at least a couple views of the product to show its dynamics. The basics are front, back, side, top and bottom. There should also be an angled view to show the product more 3 dimensionally, which could also look up or down at the product. The views used just need to make sense with the most important details of the subject at the forefront.

A few more variations to reveal more detail are the cutaway view and the exploded view. If used, a couple basic views should also accompany them.

The cutaway view takes away external areas of the product or makes them transparent in order to see the inner parts. This allows someone to understand the internal workings of the invention in relation to its outward appearance.

The exploded view is literal in the sense that the parts of an object have exploded in an orderly manner. They are floating and separated slightly to show their relationship and how they fit together. This type of drawing shouldn’t ever be the main image to represent the product. It may do a good job explaining how the product works or how it’s constructed, but it doesn’t do an adequate job showing what exactly the subject is.

Technical Illustration

Going beyond product illustration, there is a style that is more complex and technically accurate, hence its name: technical illustration. The two styles are similar and can cross over categories, but they are used differently. Technical illustration includes all of the details, workings and parts drawn in perfect proportion and perspective for precise interpretation. Think more like careful drafting. If needed, it would usually be developed more toward or after engineering. If your brochure is introducing the product, you may not need an overly detailed image, so something more straightforward would do. However, if your brochure is intended to include assembly instructions or all of the product’s working parts, etc., then technical illustration (or an exploded view) could be the way to go. And when the product starts manufacturing and selling, technical illustration may be needed for its instruction manual.

Product Animation

Another step further is animating the product in use. It is an expensive process, but 3D animation does wonders for a demonstration. A good animator can program physics into the moving image creating an accurate representation of how your product would work and move.

Producing your invention’s illustration shouldn’t be difficult. You’ve spent time thinking about what this product looks like and how it works, so you’ll have a strong mental image and probably plenty of rough sketches to work from. You may not be a great artist or you may have no idea what software to work with, but there are professionals to help. They have the listening skills needed to translate your ideas into pictures and ultimately this drawing will translate the product’s ingenuity to your audience with smooth efficiency.

3D PRINTING

Many inventors make 3D models and prototype for their initial models or prototypes.  The good news for inventors today is that many libraries have added 3 D printers which you can use. There Are about 800 3D printers in libraries Worldwide and there could be a lot more)

 According to this Google Map (see below), there are now over 800 3D printers in libraries across the world. This number could actually be significantly higher as the libraries present in Google Maps are mostly from the US or English-speaking countries such as the UK and Australia, while it is very likely that Chinese libraries alone could have three to five times as many.

Other geographic areas such as South America are also very likely to be offering 3D printing through libraries and European countries – which only recorded a few dozen in this map, are likely to have several hundreds – and even thousands – already.

The good news is that a similar map published on Google in 2013 reported only 58 3D printers in libraries worldwide, which indicates over 1000% expansion over the past four years. In 2015, according to, according to OITP Perspectives, a publication by the American Library Association (ALA) there were 250 3D printers in libraries in the US that offered 3D printing services to patrons. That number has now more than doubled to 584 according to the latest map.   https://www.google.com/maps/d/viewer?mid=1plLHXcVgwR2Ide4U1Ipl4dknZVU&hl=en_US&ll=5.943829103237726%2C-129.61664584999994&z=1

Libraries are adding new 3D printers everyday, offering services that include professional FDM, low cost FFF and stereolithography with desktop systems.
