RELATED: Designing Prototypes: 3D Design Services for Inventors and Companies<\/a><\/strong><\/p> RELATED: What Are The Main Prototypes Used By Companies in Industrial Design Prototyping?<\/a><\/strong><\/p> The main point of an ideation process is to determine \u201cwhy a product should exist in the market\u201d and \u201cwhat values it can offer\u201d to potential buyers. It\u2019s your design team\u2019s responsibility to make sure that the entire development process is actually based on a real market opportunity.<\/p> You\u2019ll be hard-pressed to find any modern product design firms that build the first prototypes without any kind of CAD tools. Gone are the days when designers and engineers solely depended on hand-drawn diagrams and physical mockups to validate ideas. Design software has reached a point of photorealism where any design team can put the entire technical foundation of a product on a screen for advanced analysis and simulation. Don\u2019t get this the wrong way. CAD modeling services<\/a> exist not to make physical prototyping obsolete; it exists to make the process much more time-efficient. Think of virtual prototyping as a preview of how the product will look and function, and what materials to use. Major areas to explore with digital models are listed below.<\/p> RELATED: Complete Guide to Prototyping Methods Used in Product Development Services for Companies and Firms<\/a><\/strong><\/p> RELATED: 10 Tips on How To Find the Best Prototype Engineering Firm Services<\/a><\/strong><\/p> A lot of the digital modeling phase is about experimenting with various design iterations. Everything is done in a virtual environment to save cost and time. Only when the 3D models and analysis results are found to meet the design requirements, the design engineering team<\/a> proceeds to build physical prototypes.<\/p> It\u2019s an early form of a physical prototype whose sole purpose is to demonstrate nothing but the fundamental feasibility of a product. PoC is never meant to be functional, let alone resemble a finished product. At this phase, your team’s goal is to validate whether your product concept and their process are feasible and manufacturable. Sometimes, a PoC prototype often involves creating a low-fidelity physical model to prove the feasibility of your idea. That’s why it’s important for you to get the best team that you can get. You can follow this workflow.<\/p> RELATED: How to Make a Prototype for Your New Product Design<\/a><\/strong><\/p> During this stage, public tests that will involve other random participants are prohibited to avoid launching it in public and IP concerns. The feedback from all the involved persons in the team is used to benchmark revisions and design refinement.<\/p> A PoC prototype is best described as a process to minimize development risk. All the initial concept validations, the scrapping of unnecessary features, and perhaps the additions of must-have functionality happen here at this phase. It\u2019s an important step to answer all the fundamental questions about the product concept and remove all the doubts about its viability. At the end of this phase, the team should be able to come up with definitive design requirements, core product functionalities, an estimated development timeline, a projected development cost, and success criteria.<\/p> All the refinements from the previous phases are mostly applied to the digital model, so that the next prototype (usually a 3D printed one) already shows some improvements over the original PoC. This is why a final PoC prototype is optional; instead of wasting resources on another PoC, the team can go directly for a mock model. Rapid prototyping services<\/a> using a 3D printer is pretty affordable these days, allowing the team to evaluate the dimensions, ergonomics, and general form factor without having to invest in injection molding or any other expensive fabrication method. For electronic products, a mock prototype serves as an early sample of the enclosure size and shape. This phase mainly concerns the following points.<\/p> RELATED: Key Differences between Prototyping and Prototype Engineering for Companies & Firms<\/a><\/strong><\/p> Mock prototypes are simplistic, but much more refined than the utterly crude PoC. In most cases, the design team deliberately avoids giving the prototype a detailed treatment to allow for quick iterations. A mock prototype created by a professional prototype manufacturing designer<\/a> is the first real gateway to an early discovery of mistakes, identifying potential issues, finding new opportunities for design improvements, and basically learning unexpected lessons. <\/p> RELATED: Prototype Design Engineering: How Well Should Your Company\u2019s Prototype Function?<\/a><\/strong><\/p> There can be multiple rounds of mock prototyping. Each iteration is based on the feedback gathered from the previous model. The team goes back and forth between the CAD software and 3D printer to make big and small adjustments to the model until the iterative process delivers the desired result. Adjustments aren\u2019t always about major design changes. They can be anything from a tiny reduction in material thickness for better ergonomics to cosmetic changes.<\/p> Additive manufacturing is the technology of choice, mostly thanks to its speed and affordability. If the additive manufacturing designer<\/a> expects to make more than several iterations within a relatively short period of time, a 3D printer is the best tool for the job. CNC machining (which is a subtractive manufacturing technique) is the next best thing if you want to build a physical model using metal materials. But both are relatively low-cost fabrication methods, ideal for creating non-functional prototypes. At the end of the day, discovering design mistakes in this phase is certainly cheaper than fixing them later in the next stage of product development.<\/p> At this point, your team has already produced a prototype that can be tested in real-life conditions. This allows you to check for flaws, features to be improved, and additional features you might want to add. All of your chosen visual design and functionalities are presented here to mimic a real product. Also, your engineers use your real materials instead of the 3D printers, but depending on your decision, you can use other fabrication methods such as CNC programming services<\/a>, laser cutting, and vacuum casting. These are the things you should check during this testing.<\/p> RELATED: Benefits of Outsourcing CNC Machining Services for Your Company\u2019s Prototype Design<\/a><\/strong><\/p> RELATED: DFM For New Product Design Excellence: Complete Guide for Company Success <\/a><\/strong><\/p> A functional prototype should be built to the same quality standard as the desired final product\u2019s specifications in every single aspect. That said, the team cannot just assume that the prototype at this point is perfect in every way. No product development process is completed without user testing, which almost definitely leads to the discovery of shortcomings. This is only the nature of users\u2019 feedback; a perfect product doesn\u2019t exist. Some of that feedback, whether constructive criticisms or otherwise, is valuable insight into the market. It tells the 3D CAD drafting designers<\/a> what features most buyers like and dislike.<\/p> Bear in mind that not every feedback can be implemented in a practical fashion without a major design overhaul. For example, some buyers might find the carbon fiber handle to be an unnecessary feature of a claw hammer. It adds too much of a premium when the more affordable materials like wood or fiberglass will do. At the same time, the material of choice is important because you want to differentiate the product from an ocean of alternatives in the market. It is the design team\u2019s responsibility to respond to (or act on) the feedback. If the overwhelming majority of the feedback expresses the same concern, a design modification can be necessary. But because this can also lead to a major overhaul, which increases the development cost even more, there should be a middle-ground solution as the team sees fit. <\/p> Based on the results of real-world user testing and adjustments made according to the feedback, the product development team<\/a> once again refines the functional prototype into an almost production-ready model. Most companies will not make a final prototype until they make sure that there will be no more major changes to the design. They\u2019ve invested so much time and money into the development effort that another modification can cause months, if not years, of setback. Also, a lot of hardware startups use final prototypes for pre-sales, attracting interest from distributors and retailers, or pitching investors. They just can\u2019t afford to make another revision, not without risking a blowback. You can say that the final prototype is the culmination of iterative refinements throughout the previous phases. A final prototype focuses on the following points.<\/p> RELATED: Why Prototype DFM Services Are Useful for Product Design at Companies and Firms<\/a><\/strong><\/p> The idea behind a final prototype is to prepare for the transition from development environment to mass production. Creating a final prototype isn\u2019t just about fabricating a physical model, as it also involves proper documentation and quality control, allowing for a smooth handover to the production team.<\/p> RELATED: 8 Tips Companies Use to Simplify Design Manufacturing or Design for Manufacturing<\/a><\/strong><\/p> Note for electronic products:<\/em> all the prototyping phases mentioned above apply to just about any physical product development, except for electronic design services<\/a>. If the product requires PCB and embedded firmware of any kind, the prototyping phase focuses first on the circuit design, along with the features and user interface (especially if the product comes with a screen\/display), before it moves forward to the physical enclosure design. That being said, the general principle remains the same that prototyping is an iterative process from ideation all the way to a production sample. <\/p> In every product development, planning and implementation are the crucial steps that can affect the very outcome of your product. From choosing your team, to rough sketches, iteration, creating functional prototypes, until the final production, is beneficial to the success of the product. This is the cycle of any project, and each cycle allows any team to learn from the previous mistake and improve the model, leading to a successful project and product.
