Understanding Prototype Development Phases

A shared understanding of the functional value for each phase of prototyping is critical to meeting the expectations of everyone involved in a project, from designers to CEOs and investors.

Prototyping at each stage of development has benefits that need to be understood to justify the cost and time invested in its development. For many medical device startups, the founders have not experienced product developers and do not understand this process.

Device prototyping phases should be aligned with project control documentation requirements.

Appearance model

Appearance models can include drawings provided by industrial designers, or physical models made of foam or 3D printing. It may look like the final product. Used to demonstrate drive size, color, control, size/position, and other visual characteristics.

In some cases, an appearance model may be a series of images examining a series of product configurations. It should be completed in weeks, not months, and can be used to gauge investor interest and gather feedback from end-users.

Proof of concept

Prototypes (PoC) Prototypes are physical desktop mockups and mockups. They are used to evaluate the performance of technical subsystems or components for feasibility. For example, pipe clamp designs may be rated for pressure resistance or flow control capability, or DC-DC converters may be rated for load and noise heating and line/load control.

PoC prototypes are used to evaluate user interface usabilities, such as B. functionality of an active graphical user interface (GUI) layout or the ease of loading a set of tubes into a pump panel layout.
