How long does it take to design a product?
No project is the same, the complexity of your design and safety requirements will dictate the length of the project. We collaborate closely with you to ensure that the product meets all the requirements to be successful and maintains your vision. We outline project time estimates in your own bespoke quotation.
Do Duku work with entrepreneurs?
I have an innovative idea, but I don't have a final design yet can you help?
Yes, absolutely. We commonly work with clients who only have an idea and need our help to turn that into a product. We will guide you through the initial stages of ideation, conducting research and concept development, to visualise your idea. Which can be made into 3D CAD designs and Prototypes.
How involved can I be in the product development process?
We believe in close collaboration; your dedicated designer will be available to liaise and discuss the project with you at all times through the product development process, we hold regular reviews over phone/video call and our UK clients are always welcome to visit our Cheltenham product design studio.
How do I protect my invention idea from being copied?
We operate under strict confidentiality and ISO 9001 standards. When working with us and any of our suppliers, we operate under a legal non-disclosure agreement. We would never share you project with anyone without your permission. When the product is well developed our Patent Attorneys, Albright IP, can help patent your invention.
Do you own my invention idea?
No. You own any ideas and intellectual property developed during the project.
Do Duku work with businesses?
Can you work with existing product lines for redesign or improvement?
Yes, we can enhance functionality, update aesthetics and incorporate new features to breathe new life into your current products or develop new product lines. Our wide range design services mean we can handle the whole project in-house. A great example of this is our work with Tug-e-nuff dog toys.
I can you work with my current manufacturer or do I have to use your manufacturing partners?
Yes, we can work with your manufacturers. We will work with you both to determine the best point to fully integrate with them for successful design for manufacture. Alternatively, we can guide you through production quotation, design for manufacture and mass production with our own trusted supplier network.
How do you handle unforeseen challenges during the design process?
Design projects often come with unexpected challenges. Our team is adept at problem-solving and we approach challenges with creativity and flexibility. Open communication with clients allows us to address issues promptly and find effective solutions. Your project will have a dedicated project manager to see changes are acted on quickly.
How do you stay within regulatory compliance when designing products?
We stay informed about industry regulations and standards relevant to your product. Our designs are developed with compliance in mind and we work closely with testing and certification bodies to ensure that your product meets all necessary requirements while still meeting your product specifications.
What is concept development?
Why do I need concept development, I just want to build a prototype?
Carrying out thorough research and working through design concepts allows us to build the foundations for a successful product. During the concept phase, we explore key functional and styling features that inform and guide the design process before moving into prototyping.
How do you approach the initial concept development of product design?
Our concept development process typically begins with a thorough understanding of your vision, target audience and market. We conduct market research, ideation sessions and collaborate closely with you to define the project scope. Our team will generate ideas and concepts to help broaden the potential IP and ensure the design taken forward is strategically and thoughtfully developed from the outset.
How do you approach product design user experience (UX)?
User experience is integral to our design philosophy. We consider how consumers will interact with a product, ensuring that it not only looks appealing but also functions seamlessly and intuitively. Our goal is to create designs that are accessible and user-friendly, making them usable by many, not just a few. A prime example of this approach is our award-winning accessible EV charger.
I want to design a sustainable product. Can you help?
Sustainability is a core consideration in our design process. We explore eco-friendly materials, energy-efficient technologies, and design strategies that reduce environmental impact—without compromising on quality or performance. Where appropriate, we use Life Cycle Assessment (LCA) to evaluate the environmental impact of a product across its full lifespan, helping us make informed design decisions from concept through to end-of-life.
What is 3D computer aided design (CAD)?
What is CAD Engineering?
CAD stands for Computer-Aided Design. CAD engineering uses computer software to create digital 3D models of products. These models can be used for a variety of purposes, including design visualisation, prototyping, engineering analysis and manufacturing.
Why Is CAD Engineering Important?
CAD engineering is important because it allows our expert product designers to design and develop products more efficiently and effectively for our clients. CAD software allows us to visualise your product, develop mechanical features and product styling so that designers and clients can analyse, understand and develop the design before building prototypes.
Do I need a CAD model, I just want a prototype?
CAD allows us to explore features in 3D, ensuring that parts are big enough, strong enough and will fit correctly. It is almost impossible to create a prototype without 3D CAD, as almost every manufacturer will use CAD in some way to create a prototype.
I already have a CAD model can you use that?
We’re committed to ensuring your product is as refined and production-ready as possible. To meet manufacturing requirements and tolerance standards, we may need to rework or completely rebuild CAD models. This ensures the design is not only high-quality but also optimised for efficient and accurate production by our manufacturing partners.
What is a prototype?
What is prototyping?
Prototyping is a vital step in developing and validating product concepts, functionality, and design. At Duku, we offer a range of prototyping design services to bring ideas to life—enabling us to test, evaluate, and refine models to ensure the highest standards of innovation and usability. Our iterative process helps identify potential issues early, optimise designs, and streamline the path to manufacturing.
What is 3D printing?
3D printing is a process of creating three-dimensional objects by layering materials. 3D printing is an additive process whereby layers of material are built up to create a 3D part. 3D printing can be a quick and cost-effective way to produce prototypes or low volumes of products.
Why is prototype development important?
Prototype development is a crucial phase in your product design project at Duku because it allows us to transform concepts into tangible, testable models. By creating product prototypes, we can identify potential design flaws early, ensure the product meets user needs, and test functionality. This iterative process of designing, prototyping, and refining helps save both time and cost by addressing issues before full-scale manufacturing begins.
How do I make a prototype of my idea?
First, we will guide you through new product development stages, including concept development and CAD design. Once the design is ready, we use a range of prototyping techniques—such as 3D printing, vacuum casting, CNC machining, and metalwork—to produce a functional prototype tailored to your project’s needs.
How many prototypes do I need before manufacture?
Prototyping is as important as concept design for exploring and refining ideas for manufacture. While simpler products may be developed within a single prototype development stage, more complex designs often require multiple iterations to achieve the best results. When you request a quote, we’ll provide a bespoke plan outlining the costs and next steps tailored to your project.
How much does it cost to make a prototype
The cost to create a prototype can vary depending on the complexity, materials and specific requirements of your product. Generally, our prototype design services range from a few hundred pounds for simple 3D-printed models to several thousand pounds for more intricate designs involving advanced manufacturing processes.
Do Duku design electronics?
What is electronic engineering?
Electronic engineering focuses on the design, development and testing of electronic circuits, devices and systems. It involves designing and developing the electronic circuits and systems that form the backbone of modern electronic products such as mobile phones, computers, robotics and electrical equipment.
What electronic engineering services are offered by Duku?
Our electronic engineering projects range from small, low power wi-fi and Bluetooth devices to large electromechanical drives and displays. In house circuit design, PCB layout, firmware, prototyping and testing ensure efficient electronic system integration throughout the design process.
What is a PCB? How are PCBs used in product design?

If an electronic product we are developing would benefit from an app, we can work with you to design the layout and functionality of an app, and guidance on aesthetics. We don't currently design and develop apps in-house. Although we are happy to work with a company of your choice to help them develop an app which can make your product function.
How do I patent my invention idea?
What is Intellectual Property?
Intellectual property (IP) is the process of protecting a physical product, graphic design or name. Protecting these assets can protect your idea and brand from being replicated. Patents and registered design rights can be used to protect physical products. Trademarks can be used to protect a brand name and/or logo.
What is a patent?
A patent is a legal instrument which is submitted to a national body to give you the rights to your invention or development. Once granted, the patent ring-fences your piece of the market and gives you the power and control to solely manufacture and sell your idea. Depending on the country your idea will be protected for between 15 - 25 years.
Can I patent my idea?
To patent an idea, it must be both unique (i.e. novel) and sufficiently clever (i.e. inventive), then granted patent rights can be obtained.
How do you patent an invention?
Patents are submitted to the UK Intellectual Patent Office (UKIPO), where the claims being made by them are reviewed. The UKIPO may ask for amendments to allow the patent to be successfully accepted. This process can take time and is often best performed using an experienced patent attorney.
Who are Albright IP - Patent Attorneys?
We are twinned with Patent Attorney firm, Albright IP, with over 25 years of IP experience to offer advice and assistance.
How do I manufacture a product?
What is design for manufacture?
Design for manufacture is the final stage of a product development project. Within this stage our product designers ensure that your working product meets the requirements of manufacturers and their machinery.
How to get a product manufactured?
Once your product has finished development, Duku can help take it to manufacture. You will need a set of design files including 2D technical drawings, 3D CAD models and a bill of materials to approach manufacturers. All of which Duku can produce for you.
How do I find a manufacturer for my product
Duku has a network of approved trusted suppliers who we have worked with for over a decade. Capable of working on small simple products, through to large electro-mechanical products and even medical devices. Working with our suppliers streamlines the production quotation and manufacturing stages of your product. You can source your own manufacturer but it can take a lot of time to find the right manufacturer, who can produce your product at the right price and quality.
How much does it cost to manufacture a product?
We are often asked this very early in the project. We need to approach a manufacturer with a completed set of design files, where we can accurately quote the production cost of your invention. So we have to complete earlier concept development, CAD design and prototyping phases before we can investigate manufacturing costs.
What country should I manufacture in?
Duku are big supporters of UK manufacturing. There are many benefits to having a local supplier you can visit. So wherever possible we will suggest a UK based manufacturer. However, if this isn't suitable, we have worked with a select group of trusted Far East suppliers for many of our projects for over 10 years.
How do I brand a product?
What makes a good brand name?
Picking a brand name is very subjective and personal. We advise you ensure it is unique so that you can use a matching company name, website address and trademark.
What makes a good brand?
There is no right or wrong. But the look of your brand should tie in with your brand name and the industry it is being sold into. A strong brand is built from carefully selected colours, shapes, images and fonts. Our team of experienced designers can also create your branding if this is a new venture, ensuring it perfectly aligns with the development of your product.
How do you ensure that the final product aligns with our brand identity?
We prioritise understanding your brand values and aesthetics. Our design process not only involves meeting your product specifications, but also includes collaboration with your team to ensure that the final product aligns seamlessly with your brand identity and resonates with your target audience.

How do I successfully launch a product?
What are the routes to market for my invention?
There are many routes to market you can consider, depending on whether you want to manufacture the product yourself, or just sell the idea to someone else. There are three main methods of selling a product; selling, licencing and manufacturing.
How do I sell my idea?
If you have developed an invention but don't want to manufacture it yourself, you can sell the ownership of the product idea outright to someone else. For this it is advised you have intellectual property in place and that you have developed your idea enough that it has a clear function and has solved any issues found during development; ideally with a functioning prototype. Once you have done this you will be able to approach people and companies for a single payment for your idea.
How do I licence my idea?
You can licence the use of your invention for a set period, for someone else to manufacture it, taking a yearly payment or percentage of sales revenue in return. For this it is advised you have intellectual property in place and that you have developed your idea enough that it has a clear function and has solved any issues found during development; ideally with a functioning prototype.
How do I manufacture and sell my own product?
If you want to develop, manufacture and sell your own product. You will need to find a suitable manufacturer to create an initial production batch. Once produced you can sell your own product. We have a range of suitable manufacturing partners who can help.
What innovation funding is available?
How can I find a private investor?
With Duku’s help, we will ensure your design is thoroughly developed, professionally presented and commercially viable, de-risking the investment to a funder.
