A prototype engineer designs and develops a prototype product, starting with brainstorming and design, creating a non-working model, and finally a working prototype. They may need to create multiple models and go through multiple iterations before completing the work.
A prototype engineer is typically responsible for overseeing the design and development process of a prototype product. This usually starts with a brainstorming and design stage, where an engineer comes up with a concept or uses someone else’s ideas and design to start developing a realistic approach. A model is typically created from the prototype, either in physical form or as a computer-generated object that can be tested in a virtual space. The actual prototype is usually created by an engineer for use in demonstrations or as the first step in future development.
One of the first responsibilities a prototype engineer often has is to create a concept or blueprint that can be used to develop a prototype. Exactly how an engineer does this can vary widely, although it often starts with brainstorming and countless iterations on ways to develop the product. The engineer may also need to work from someone else’s concept and find a way to actually make it work. This could be a rough concept described in general detail, or it could be a fully conceived product that needs to be developed by the engineer to make it practical.
Once the basic design is established, a prototype engineer often creates some kind of non-working model or version of a product. This is usually done to get started with seeing how parts need to be sourced or manufactured, and to test out the overall look and initial usability of a product. Physical models can be created by an engineer, often used to ensure an item can fit part of a larger object of which it may just be a component. Computer-aided design (CAD) programs are often used to create a digital model of an item that can be tested and analyzed in a virtual environment.
When these development steps are complete, a prototype engineer typically creates a working prototype of an item. This can be one of the most difficult and complex stages of the process, as different faults need to be found and multiple tests are performed on the prototype. A functional item is important, however, as it is often used in demonstrations and to show practical applications to others within a company. The first version of an item is rarely used; therefore, a prototype engineer may need to create multiple models and go through multiple iterations of a product before completing the work.
