What Is Prototype Development?
To explain what prototype development means, let’s first look at what it consists of. A prototype is a copy or replica of a part that is used to show how a product works and all its possibilities before investing in making a complete part. Prototypes can range from detailed drawings made with pen and paper to actual working products. Thus, prototype development is simply a series of processes by which a manufacturer makes a prototype. Many people also refer to prototype development as “prototyping.”
For example, a company might start with detailed sketches to visualize a new product. Then, they could create a 3D-printed model to test its functionality and design. This step-by-step process is a fundamental aspect of prototype development.
Different Types of Prototype Development
Prototypes can be categorized into four types based on how the product is designed and how the manufacturer wants the final product to work. They are:
| Type | Characteristics | Uses |
|---|
| Working Prototypes | Contains as many features and functions of the final product as possible; the most common type of prototyping | Used for testing product functionality and gathering user feedback |
| Functional Prototypes | Created with steps similar to working prototypes, but generally at different scales and techniques | Validates specific functions and tests various design concepts |
| Visual Prototypes | Shows the shape, size, and layout of the product; does not need to demonstrate functional features | Used for early design review and visual feedback |
| User Experience Prototypes | Provides sufficient information for future research and can be used in the manufacturing process | Researches user interaction, gathers user experience feedback |
How to Create a Prototype in 7 Steps
If you want to learn how to create a prototype, consider following these steps:
Conduct Research
When you have an idea for a product, the first step is to research similar products. This will help you determine whether your idea is innovative. Searching for and analyzing similar products will also help you understand what these products are made up of. In addition, you can see how they work together to form a functional product. This will give you an idea of how the product can be manufactured and how it will function once it is made.
Drawing Up a Design Plan
Before you can make a prototype, it is important to design the product. Sketches can help you to roughly determine the appearance and function of the finished product. These sketches only represent the initial product idea. It is therefore crucial to find a design you like, as it may need to be revised several times. The subsequent steps can take more time and money than this stage. It is therefore often helpful to develop several designs and focus on the one you think is best.
Developing a Virtual Model
The next step in creating a working prototype is to generate a virtual model of the product. With the help of 3D imaging software, you can create a realistic model of the proposed design. When creating a virtual model, it is helpful to consider the materials that would be most suitable for the final product and how different shapes affect the product’s functionality. This can help you create a model that accurately represents how the product will look and function when built.
Deciding Whether You Need Help
After you have created a model of your product, you can decide whether you can make a prototype on your own. If your prototype requires a specific machine to make, consider getting help from someone trained to use that machine. For example, engineers and prototypes can help you make a prototype. Getting help from any expert you choose will enable you to make a prototype safely and efficiently. They can also use their expertise to suggest improvements to your design.
Generate a Proof of Concept
A proof-of-concept prototype shows how your product will work. It may not look exactly like your final product. However, it is important that your proof of concept includes the moving or mechanical parts of your design. This will help you understand how each part works together. As a result, it will help ensure that the product you build will work as intended.
Create a Prototype
Once you have determined that a functional product can be created, you can create a version that is more in line with the model and design. For this prototype, you can combine the visual ideas in the design with the functionality of the proof of concept. With this information, you can also determine which parts of the design work and which need to be adjusted.
Repeat Any Steps as Needed
Once you have tested the prototype or had it used by your target audience, you may find areas for improvement. Consider going back to the sketch, 3D model, or proof of concept and make any necessary changes. In addition, you can repeat these steps as needed to find the best combination of function and design for your prototype. You can then show potential investors the prototype you have mastered or start producing your product.
Why Is Prototyping Important?
Every company that manufactures components needs to go through the prototyping phase because it is crucial. Here are some reasons why companies cannot skip the prototyping phase:
Prototyping for Marketing the Product
Creating parts or products that customers or stakeholders won’t support is a waste of time. Selling a product with a prototype is more convincing to clients or customers than selling one without it. For example, when presenting a new gadget, having a prototype allows potential investors to touch, feel, and interact with it. Their feedback is essential for making significant changes to the final product design.
Prototyping to Put Ideas into Practice
Drawing up a design for a part doesn’t guarantee it will work in real life. Prototyping allows you to see how the part functions in a real-world environment. For instance, a prototype of a new engine component can be tested under actual working conditions to identify necessary modifications or eliminations.
Prototyping to Minimize Production Costs
Some might argue that building prototypes costs money that could be spent on production. However, the amount spent on prototyping is minimal compared to the money wasted using the “trial and error” method. Prototyping helps identify changes needed for the final product, providing a more accurate estimate of production costs. For example, a prototype of a new phone can show pricey design flaws. It does so before mass production starts, saving lots of money.
The Difference Between a Prototype and a Final Product
Prototypes and final products serve different purposes. They often differ greatly in materials and how they are made. Here are the key distinctions:
Materials Used
- Prototype: Typically made with inexpensive materials to save costs during the testing phase. For example, a prototype smartphone case might be made from a cheaper plastic.
- Final Product: Uses high-quality, durable materials intended for long-term use. The final smartphone case, for instance, would be made from premium materials like hardened polycarbonate or aluminum.
Manufacturing Methods
- Prototype: Utilizes rapid and flexible methods such as prototyping 3D printing or CNC machining. These methods are quick and cost-effective but may not be suitable for mass production.
- Final Product: Employs mass production techniques like injection molding or die casting. These processes are more complex and expensive but necessary for large-scale manufacturing.
Quantity Produced
- Prototype: Produced in small quantities, often just a few units, to test and refine the design. For example, a company might create a few prototype units of a new toy to test functionality and safety.
- Final Product: Manufactured in large quantities to meet market demand. Once the toy design is finalized and approved, thousands or even millions of units will be produced.
Appearance and Finish
- Prototype: This may have a rougher appearance and finish due to the use of less refined materials and processes. For instance, a prototype car part might show visible tool marks.
- Final Product: Has a polished and refined appearance, with smooth surfaces and professional finishes. The final car part will be polished and coated for aesthetics and durability.
Purpose and Testing
- Prototype: Used for testing design concepts, functionality, and user feedback. It allows manufacturers to make necessary adjustments before mass production.
- Final Product: Ready for the market, designed for consumer use, and meets all quality and safety standards.
Stages of Prototype Development
As mentioned earlier, the process of making a product prototype development is divided into three main stages. They are respectively the following phases:
Alpha Stage
In this step of making a prototype, the prototype can answer two questions:
- How does the manufactured part look and feel?
- Does it work properly?
In most states, a separate prototype is made for each question. However, some manufacturers may make the same prototype for both needs. It all depends on the circumstances. The model that a manufacturer makes to answer questions about how a product will look and to show if an idea works is called a prototype.
A proof-of-concept prototype checks to see if the parts work. This prototype is not concerned with how it looks. Its main purpose is to test how the program currently works. Thus, the manufacturer can check if the plan works before starting. Cardboard, motors, switches, and other cheap and easily available parts will be used in it.
Once the manufacturer is satisfied with the proof-of-concept prototype, an exterior prototype is created. This prototype is mostly about how it looks and may not even have any functionality. More expensive materials and machining methods are also used in making the prototype. At this stage, they are usually made using 3D printing.
Manufacturers can also use it to market to possible buyers and other stakeholders. This allows customers and other important people to see the results. Also, the manufacturer can get good feedback for the next stage of prototyping. If this step goes well, the machinist will start preparing more complex machining methods, such as CNC machining, for the next prototype.
Testing Phase
In this phase, feedback from customers and partners in the alpha phase is used to create better prototypes. During this phase, the product looks and works closer and closer to the finished product. At this point, the prototype has been tested extensively during this phase. The engineering prototype and the production prototype are the two prototypes made in this phase.
The engineering prototype is better than the proof-of-concept prototype made in the alpha process. Its goal is to produce a replica of the final product that will look, be manufacturable, and be operable. Based on previous feedback, this version has become more advanced. At this stage, the machinist uses more complex methods to build things, such as injection molding and sheet metal fabrication. This is done to make it look as much like the end result as possible. The machinist will use quality materials to make the prototype.
The manufacturer will test the prototype again in implementation conditions to see if the new product will live up to expectations. Once the manufacturer is satisfied with the engineering prototype, they will create a production prototype. This is the last prototype that needs to be made before the design is accepted for tooling and mass production. This prototype should look the most like the final product because it is close to mass production. However, it may not use the expensive materials used to make the finished product.
Some machinists may make prototypes that are both research and production models at the same time. However, much depends on the product’s risk assessment. Finally, the machinist uses the production prototype to make final selections. This includes everything from comfort to final acceptance of the design. Once the test and production costs have been agreed, the final product can be mass-produced.
Pilot Phase
In this phase, the machinist produces the final or test prototype. This is the first batch of the product because all the other parts look the same as long as there are no other problems. The only reason the machinist calls it a prototype is that it needs to be approved first. Some changes are still possible here. For example, the way some of the metal and plastic parts are manufactured could be changed, such as using injection molding and CNC machining.
Once no other changes are made, the machinists send the test prototype to different review groups for approval. Once these approvals are granted, they can finally start manufacturing the product on a commercial stage.
Some machinists may use different terms such as proof of concept (POC) and minimum viable product (MVP). But for prototyping, these three terms are almost universal.
Common Mistakes in Making Prototype Development
Making mistakes in the prototype phase can cause big problems in the final product. Here are some common mistakes and tips on how to avoid them:
Not Seeking Expert Opinions
Failing to consult with experts can lead to critical errors in the prototyping process. Experts can provide valuable insights and guidance at each stage of development.
Tip: Always seek advice from experienced professionals to ensure each stage of prototype development is handled correctly.
Poor Cost Estimation
Underestimating the costs involved in prototyping can derail the entire project. Accurate cost estimation is crucial for budgeting and resource allocation.
Tip: Perform a thorough cost analysis before starting the prototype development to ensure you have a realistic budget.
Insufficient User Feedback
Not gathering enough feedback from users can result in a product that does not meet customer needs or expectations. User feedback is essential for making necessary adjustments and improvements.
Tip: Engage users early in the prototyping phase and regularly collect their feedback to refine the product.
Rushing the Prototyping Process
Trying to complete the prototyping process within a fixed timeframe can lead to incomplete or faulty prototypes. Depending on the complexity of the part, the process may take longer than anticipated.
Tip: Allow adequate time for each stage of prototype development to ensure thorough testing and refinement.
