The availability and affordability of advanced computer technology has paved the way for increasing utilisation of digital prototypes created in computer-based scenarios, i.e. they are virtual as opposed to being physical.
Prototyping and evaluation measures are inseparable from the design process in the manufacture of a product. Many physical prototypes require very expensive and time consuming efforts, so the technology of Virtual Reality Tech is required to achieve quick and precise decisions. VR is required for simulations that require a lot of interaction such as prototype assembly methods.
Modern physical prototyping and virtual prototyping techniques continue to advance and become more powerful. The question is which options are most appropriate? Several criteria, including physical, operational and application considerations, need to be satisfied by the chosen prototyping methods. These requirements include but are not limited to time, cost, material properties, modeling accuracy and reliability, size, quality, level of detail, etc.
Existing prototype methods may or may not satisfy such requirements depending on the design requirements. Therefore, the merits of each option need to be assessed against the individual requirements of each enterprise and its specific products. Ultimately, the ideal prototyping solution, whichever form it may take, is the one that can quickly, and accurately, generate a design that will have high quality and low production cost in the shortest time.
Successful virtual prototyping requires comprehensive integration of and communication between various analysis tools so that new products are designed with inputs from all concerned. This in turn requires easy data conversion and compatibility.
The implementation of virtual prototyping is more successful and less difficult to achieve at component level than at system level because the latter necessitates comprehensive modeling of complex interactions between constituent subassemblies and components. virtual prototyping at the system level may only be achieved with full integration of product and process data, although it can be expensive in the short term. However, integration can give long-term dividends through more effective virtual prototype solutions.
Repeated, efficient, and extensive use of prototypes is a vital activity that can make the difference between successful and unsuccessful entry of new products into the competitive world market. In this respect, physical prototyping can prove to be very lengthy and expensive, especially if modifications resulting from design reviews involve tool redesign. The availability and affordability of advanced computer technology has paved the way for increasing utilisation of prototypes that are digital and created in computer-based environments, i.e. they are virtual as opposed to being physical.
The rapid increase in both computing power of computational methods and models of physical phenomena and the growing ability to transport results between various models are improving the scope of applications, robustness, accuracy, realism and cost effectiveness of virtual prototyping technology at an incredibly fast pace Virtual prototyping. consists of many capabilities, the best known of which is the creation and viewing of 3D solid models with various colours and surface textures
The purposes for which prototypes are used are universal, irrespective of whether the prototype is a physical or virtual one. In general, prototypes are required for three main purposes: communication, design development, and design testing and verification
The system, subsystem or product at a given level of the design process and their functions must be defined, and the scope of the tests must be determined e.g. short-term normal or extreme long-term conditions. Using computer simulation, all or parts of the possible scenarios can be simulated in order to study the behaviour of the selected functions, system or subsystems involved.
Selecting the right type of prototype for your project depends on your stage in the process and your learning goals. If you need to test a complex or involved interaction, you will run into the limits of some tools, and need to move to a real front-end implementation. But you probably don’t need a real back-end implementation unless you truly need persistence across sessions for your prototype.
Basic digital tools can serve most mid-stage needs, saving significant time by avoiding having to create a real back-end. What matters is that you have an experience that looks and feels like the real thing—but it doesn’t have to work like one.
The right tools will allow you to quickly build prototypes without needing lots of time or expertise. All these tools have some advantages and disadvantages. But before getting into selecting the tools, you must define the selection criteria to make an informed decision.
Are there tools your organisation is already using that are appropriate for different prototypes? Is there a possibility to re-use some of them? It helps to create a gradual change in organisation instead of a radical change and helps in adoption of the learn-build-test-repeat model. What types of prototypes does your organisation not have tools for? Discover your gaps, and find new tools to fill them.
Requirements lead to security questions: Who should have access to your prototype? Will users need to create an account? Who will be able to make changes to the prototype? Are there security provisions that must be in place for new information you collect? Is there an established way to access actual customer information in an unfinished product, while maintaining your standards?
Most of the time, prototypes are testing beds, and whatever gets built as part of the testing prototypes is discarded. But that need not be the case, if you want to use elements of the prototype design in your actual product. Especially in later stages, choose tools that will help in the transfer.
Based on your stage of the process and prototype needs, consider criteria tradeoffs involved in these decisions, so it’s always valuable to have all necessary information before you make any decisions.
Building prototypes and fostering team innovation is different from everyday work. It’s all about building a different model, developing learning goals, and adapting your standard processes. So to be successful, it’s crucial that your innovations are separated from daily organisational operations and constructed carefully. Remember to be patient, smart, and strategic at every step of the process.
Using a template makes it much easier to get a good result. Then start with digital prototyping. What’s amazing with this kind of zero-cost prototyping is that you can upload designs for instant quotes—with no commitment to buying. When determining how to make products, this step is very important because you can upload numerous variations of your product designs to easily and immediately see what design choices will decrease costs.
Once the digital prototype looks good, print it out on paper. This is the first way to get a sense of what your product will look like at 100% scale. It’s easy—and it’s free. You’d be surprised how easy it is to misjudge scale on screen.
When you get these initial samples in hand, take a really good look at the design. Is it what you envisioned? Do any slotted parts fit together perfectly? If not, now is the time to adjust so they better align with what you had intended. The result of this revised design will naturally be a new prototype, followed by another round of assessment.
Continue revising the design until you’re confident in the quality of your product. Next, make a small batch in the final material of choice. Here, you can evaluate if the material you chose will work as expected and be strong enough for its intended use. Once again, you’ll want to get some sample product in hand so users can test it out and provide feedback before you commit to a large order.
Finally, once you’ve gotten to a point where users are giving good reviews of the product, you can make a larger order in accordance with market demand.
1. What do I want to learn from my next prototype test?
You’ll want prototypes that clarify and emphasize initial plans to users, rather than focusing on the unrelated assumptions of user experience flows and other areas. Later in the process, this may change.
2. What are my constraints?
Consider the amount of time and resources it makes sense to invest at the current stage of testing. Is there enough promise and momentum that it’s worthwhile to involve designers and engineers in the development of a prototype?
3. What are my requirements?
Factor into the design process whether or not the value propositions with which you are experimenting require a mobile app prototype. Or maybe you’ll need a website that simulates advanced interactions.
4. Why Prototype?
People working in Design, and Engineering fields are very familiar with the benefits of prototyping, but let’s look at it from the client’s perspective. What are the main reasons that a client should want to prototype digital products and experiences before committing to a full on build?
There are a couple of main reasons: First, when you prototype, you get a first glance into what features your audience will actually use. Testing prototypes to ensure that what you’re building connects with and will be used by your audience is always recommended. Second, it saves money. Plain and simple. If you prototype, test, and iterate on a product early on – you will save a ton of cash before hardcore and expensive engineering even begins.
5. When should you prototype?
Prototyping is particularly useful when used alongside the Design process of product creation. It is the mechanism through which innovation and creativity can be unleashed. The stages of Design Stages include Motivation, and Implementation. Prototyping is useful in each stage.
During the motivation phase, we conduct field research to gather insight from the world around us. This includes doing a comparative analysis of competitive products and observing elements within our environments that contribute to our vision for a product. Creating low fidelity prototypes at this stage often adds fire to our inspiration.
We keep prototyping and testing through Implementation. In our experience, almost every significant project ‘pivots’ at least a little when you receive feedback on a prototype. Your first idea is rarely the best, and prototyping gives you that information. The prototypes used during Implementation get successively higher fidelity until you end up testing something that is nearly identical to the final product. That typically takes some iterations, but each iteration is well worth the time.
6. How do you prototype?
Prototypes aren’t a one-size-fits-all solution. Every project is different, and each stage during a project needs various levels of prototyping. Before jumping into higher fidelity models, it’s important to reiterate how important the lowest fidelity prototypes are to product design. Low-fidelity sketches, whiteboard sessions and lightly documented ideation are all more efficient than jumping into or even doing high-fidelity wireframes and information architectures. Those high-fidelity documents usually incur a lot of time to produce and become out of date almost immediately after creating them.
There is also value in high-fidelity prototyping. Once we’ve begun testing, we can start establishing an understanding of what our audience likes about the product we’re building. We can confidently start engineering some features that have the potential of making it into the final product.. By continuing to test these hi-fidelity prototypes, we get closer and closer to eventually landing on things that we’re pretty sure we’re going to build. But it doesn’t stop there.
We continue to “prototype” products as we jump into final engineering. At this point, it’s not technically a prototype anymore. It is real, working product that will eventually deploy. However, as the build progresses, we continue testing with users so that we can watch them break what we’re building, fix what’s broken, and do it all over again until the final product is ready. It’s important to note that ‘final’ does not mean ‘perfect’. If you wait for perfect, you run the risk of getting beat to market by a slightly less than perfect competitor, and you will lose your edge.
7. Digital prototyping
Using a Digital Prototyping workflow enables design to take place in swift parallel across all technical specialties involved. A digitally prototyped design keeps all specialists updated on exactly what is happening in every other specialty as the product or part moves through the design process and towards final production. For example, product-management sub-programs allow for on-the-fly updating of a bill of materials. So when a product's surface is bent or shrunk, the amount of on-order sheet metal changes immediately.
8. Creating designs
Digital Prototyping can bring particular benefits to users who are looking to create useful designs. Tools for Digital Prototyping, providing a comprehensive, integrated set of design tools for producing and documenting complete digital prototypes that allow designers to simulate how a design will work under real-world conditions before being built.
9. Saving time
Speed to market is an important benefit for most manufacturers, but so too are savings on physical prototypes.. By moving to digital prototyping, companies reduced time to market, cut development, labour and material costs; boost customer satisfaction by allowing customers to collaborate on design; and nearly eliminate waste because design changes were made before steel was cut or plastic shaped. In addition, the company can ‘ship’ models to customers in real time.
10. A valuable solution
The value of design tools is being recognised and embraced by a new generation of engineers and designers accustomed to living in a world that integrates virtual and physical realities into a single, unified reality. This generation of ‘virtual natives,’ with its drive to combine the physical and virtual worlds into one, is transforming existing industries and promising to create new ones.
In manufacturing, virtual design tools and digital prototyping workflows tear down previous barriers, creating a team-like system in which designers, engineers, marketers and end customers collaborate continuously from concept to production. The result is a better designed product that costs less to make, gets to market faster, increases margins, frees internal resources for innovation, and – most importantly of all meets customer requirements.
