Drawings are very important and are used to document, record, and detail your invention. Everything from the first sketch to the final manufacturing process should be recorded. The type of documents you need will depend on where you are in the Product Development Cycle (PDC.) I would highly recommend that your product be documented using 3D CAD (Computer Aided Design) software. The infinite uses and views generated by this type of design make it preferable.
Your Product Engineer or design group should be able to create detailed part and assembly drawings for production, tooling, or whatever you need by utilizing one of many CAD systems. This allows concept, patent, or illustration documents for catalogs and manuals to be generated as needed.
The documents produced should be parametric, or associated, to the actual part or assembly. Once the document is created, it automatically updates itself as the 3D file is modified. When used properly, this saves time and money in the Development Process.
Many people still use 2D (two dimensional) CAD systems, like AutoCAD. This may be acceptable in the early stages of a project, but not preferable. The disadvantage is that when you are ready for Rapid Protoyping or Tooling, you will have to pay again for 3D (three dimensional) CAD files, which by default offer the features of the 2D CAD file.
What is a Concept Drawing?
A concept drawing is a great first step and cost saver for inventors.
What is a Detailed Drawing?
A Detailed Part Drawing is needed in many cases to get quotes and manufacturing information for your invention.
What is an Assembly Drawing?
An assembly drawing is used to show fit and function, and verify how a product is put together.
Create or mimic a furniture piece. You must draw, label & dimension each piece.
You must Provide the following Drawings:
An Orthographic view of each piece (Dimensioned)
An exploded isometric drawing
A Compounded Isometric drawing
Part & Material List
Be sure to specify the scale printed at as well as a title block.
