82. How to Make a Prototype of an Invention

A prototype of an invention is a merely a detailed plan for the construction of the invention. Depending on the nature of your idea, you may also want to develop a working model of your prototype product design to show potential investors. There are a few standard steps to making a prototype of an invention.

Instructions
Step 1
Make a detailed drawing of your invention. This should be a picture of the final project as you imagine it. Include a summation of the purpose of the invention, the name of the invention, your name and address, and the date in a box in the lower right-hand corner of the drawing.

Step 2
Draw an "exploded" version of your invention in which you present your invention with all the parts separated from the end product. Use a CAD computer program if you have one. A good example to look at to understand how to make this drawing is the instructions that come with unassembled furniture. Each part is shown separately with path arrows showing where each piece goes. Include on this drawing a detailed description of the specification and purpose of each part of the prototype.

Step 3
Review your design and look for ways to eliminate cost, such as replacing materials with others that would be less expensive. For example, casting metal parts in plastic will save you money when creating your prototype. Consider the end mass production tooling costs as well.
