What is a prototype? What is an annotated sketch?

Question

please help!!

Answer 1

A prototype is in the beginning stages of production. For example, if you are inventing a new tv, you would first come up with the concept, then drawings etc, then you would build a prototype or what you want your new tv to look like. It is usually a working model of what you want the final product to look like. It is so you can fix any of the little problems that you may have. You would then build a tool (like a template) and make any changes. You are finally ready for production. I think an annotated sketch is your sketch or idea on paper of what you want you product or idea to look like that is in the beginning stages of product development. Good luck!

Answer 2

A prototype is the first working model of a final product. It is made so the engineers may make small changes and corrections in its function and design before the final design goes into production. Electronic prototypes don't necessarily have to "look" like the final product, they just have to perform like the final product in most respects. Mechanical prototypes usually have to have the same form and fit of the final product, but not necessarily have the same weight, density, etc, as the final product.

An annotated sketch is a drawing (it may be produced by CAD equipment, or hand-drawn), that has been marked with corrections (by hand, in RED ink usually) by the design engineer, test engineer, or authorized person making the change, when changes are made.

Prototypes are sometimes made from sketches, and when the changes are physically made to the prototype, the sketch is marked up, or annotated.

Answer 3

im pretty sure a prototype is the design of an invention before it is made, like what it is going to look like
