In this article, we want to answer the questions: what is a prototype? And how is a prototype designed? Introduce different types of prototypes and examine prototype design methods and models.

All the tools and devices that affect our lives today were originally a mental idea to meet our various needs. But how does a mental idea turn into a cell phone or a language learning software? The answer to this question is short: using prototypes.

What is a prototype?

A Prototype is an English word that consists of two parts, Pro meaning first and initial, and Type meaning type and species. Generally, a prototype is a prototype, model, or replica of a product used to test a basic idea or evaluate the potential performance of a product.

Using the Prototype is one of the most basic steps in the process of designing and building a product. Different types of prototypes are in all areas of design; From architecture and engineering to robotics, making mobile phones and various computer software.

The purpose of designing different prototypes is to create a basic and tangible example of the original idea or to explore and find solutions to the problems found in the basic product by users. In fact, by building a prototype, you can use a simpler but closer to reality example, instead of having to start all over the process of designing and building your product.

A prototype can also be for testing a specific feature of a product. This is more useful in designing various software. Developers of software, websites, or applications use Prototype at various stages of their project to identify potential problems before it is too late and to quickly find the solutions they need. Of course, the more complete and advanced type of prototypes in the field of website design and applications is also called MVP or the minimum acceptable product.

Advantages of prototyping

• Creating a more tangible model for the initial mental idea
• Save time designing, producing, improving the desired product
• Spend less money building a Prototype than a complete product
• Find potential problems and get proper feedback from users at various stages of the project
• Ability to share different ideas and apply them to improve the performance of the final product

Prototype types

Now that we have a general understanding of the concept of prototype, we want to discuss prototype types. In general, there are many types of prototypes. These prototypes are usually classified based on the accuracy of construction, the type of material used, whether physical or digital, and the model used when designing the prototype, so on.

Low fidelity prototypes

Low-precision prototypes are commonly used in the early stages of a project, allowing the designer to implement a variety of ideas in a short amount of time and at a low cost. These types of prototypes do not necessarily have to do with the final product and only provide an overview of what is to be built.

It is worth noting that low-precision prototypes are sometimes called paper prototypes; Because simple paper etudes are usually used when preparing these types of prototypes.

One of the advantages of low-precision prototypes is that they allow you to get constructive feedback on the various ideas you have in mind. Using this information and feedback makes it much easier to decide whether an idea is appropriate or how to improve a product.

Medium fidelity prototypes

Medium-precision prototypes are usually more similar to the final product. These types of prototypes are usually created to solve possible problems in the product and are mostly used to improve the product.

They are generally limited in terms of visual features and design accuracy and focus more on the process of improving product performance and evaluating its overall structure.

Medium-precision prototypes have many applications and a wide variety. For example, when designing Android software, a kind of medium is created by developers, also called a wireframe. In this type of it, the skeleton and general structure of the program are determined with moderate accuracy, but its function has not been determined yet.

Storyboards in the film industry are another example of medium-precision prototypes that allow filmmakers to navigate the story more easily.

High fidelity prototypes

High-precision prototypes, as their name implies, are much more similar to the final product and can sometimes be confused with the final product!

They have more visual details (such as color, texture, material, etc.) and users can use them and share their opinions about them with designers.

These types of prototypes naturally require more time and money to build and are generally used in the final stages of product development and for final evaluations. For example, 3D models made of various hotels and towers are good examples of high-precision prototypes.

6 steps of prototype design

So far we have learned what the benefits of a prototype are and how important it is to build a suitable one at different stages of the project. But the question remains, how do we design a prototype?

1- Estimate the equipment, cost, time you need.

Before you start building your prototype, you need to figure out what you need to build it. From the equipment, cost, time required to the performance you expect from your prototype.

2- Draw your idea

Drawing on your prototype design idea will help you quickly identify potential flaws and issues that you want to incorporate into your model before building a complete prototype.

You can use digital drawing software. But drawing your idea with a pencil and paper not only meets your needs but can also increase your creativity when drawing your ideas.

3- Design a virtual prototype

Once you have drawn your ideas in two dimensions, you can use a computer model design software such as AutoCAD. This software provides you with the ability to design in two dimensions as well as three dimensions.

With a 3D model, you can bring your drawing idea a little closer to reality. You can rotate your 3D model and view it from different angles. Of course, you should know that when designing a 3D model of your Prototype. You need to consider much more detail than your original design. Because this is the model based on which you are going to design your prototype.

4- Prepare a simple and handmade prototype.

Your prototype can be in your home with materials that are easily available to you. Your original prototype does not have to be very similar to the final product.

In fact, by making this simple handmade prototype, you want to see if the idea you have is feasible. Today, with 3D printers, making prototypes can be done in just a few hours without much hassle.

If you are working on an e-project, you can leave the coding and software part of the project to third-party libraries and save your time.

5- Fix problems and shortcomings

Once you have your initial prototype ready, you need to identify any issues with your design. This sometimes means that you have to prepare several different prototypes of your prototype.

6- Finalizing the design and construction of a final prototype

In the last step, after several experiments and making several experimental prototypes. You have to reach a final design and build your final prototype. This prototype should be ready for field research and feedback from target users and are for potential investors. In addition, your final prototype should be part of the performance of the final product.

Key points in prototype design

Finally, here are some general and key points when designing a prototype. We hope that you will be able to put your mental idea into action as easily as possible using the material that has been for you in this article. We also hope to bring you one step closer to the product or software you are looking for.

• Can the type of prototype you have chosen solve the problem you are dealing with?
• Pay attention to your target users and design your prototype to meet their needs.
• Perhaps the most important thing is not to spend too much time deciding on your type. Just specify your initial idea and start implementing it on it.
• Facing problems in implementing your plan and idea will not become apparent without starting work.
