Household appliance design and manufacturing is a field dating back to the early 20th century, and it has seen a steady stream of innovations that make household appliances more functional, more energy efficient, and more connected as part of the Internet of Things (IoT). By using advanced software to design their products, assembly lines, and factories, household appliance manufacturers can achieve the efficiencies needed to stay competitive in the future.
Household appliances have come a long way since many of them—such as refrigerators, electric stoves, and dishwashers—were first developed in the 19th century and commercially produced in the early 20th century. Very early household appliances had basic functionality and were—by today’s standards—comically clunky, such as the 150 kg Siemens “dust suction pump” (vacuum cleaner) from 1906. Still, they were also, without a doubt, very innovative for their time. And they resulted from early design processes that required everything to be done manually, from hand-drawn sketches to physical models and prototypes.
Since the advent of computer-aided design (CAD) software a few decades ago, household appliance design has become ever more flexible, efficient, and innovative. Today, CAD software for appliance design and other product design has become extremely sophisticated and can include simulation technology for testing appliance designs virtually, as well as computer-aided manufacturing (CAM) functionality.
All this technological progress has allowed household appliance designers and engineers to be more precise in their work and to iterate faster on their creations. But the steps of household appliance development have remained mostly in place. Appliance developers still begin with conducting market research such as surveys and focus groups, and analyzing trends and the competition to understand the desires of their target customers. Teams then take these insights into the ideation stage which may include brainstorming, mind mapping, and copious product sketching to explore new appliance possibilities.
Next, the designers start to refine the appliance’s aesthetics, features, and manufacturability by designing detailed and more precise 3D models in CAD software. Some CAD software, such as Autodesk Fusion, also offers virtual prototyping that puts product designs through simulation tests so designers and engineers can iterate in the digital realm. When it’s time to create physical prototypes, Fusion also has CAM features for setting up making on CNC machines, 3D printers, and other machines. Additional rounds of iterations put physical prototypes through stress tests, functional tests, and user tests before incorporating feedback and finalizing the design, materials, and manufacturing processes for production.
As with the design process, the manufacturing process for household appliances has progressed greatly from the mostly manual, labor-intensive product assembly and handcrafting of components used in the early days. Today, household appliance manufacturers use modern advanced manufacturing that leans on robotics and other types of automation, as well as smart factories that mine continuously collected data streams to refine quality control and quality assurance systems.
The sourcing of common materials used in household appliances, such as various metals, plastics, glass, rubber, and ceramics, still requires establishing solid relationships with reliable materials suppliers. However, manufacturing execution systems (MES) software like Fusion Operations helps companies with materials scheduling and inventory management (material requirements planning) so they can adapt quickly to any supplier changes.
Common production techniques for appliance manufacturing, such as injection molding and metal stamping, have existed for decades, but in a modern, digital factory those techniques are augmented by automation and/or robotics technology, and supplemented by newer, computer-controlled processes, like additive manufacturing, subtractive manufacturing CNC machines, and hybrid additive/subtractive techniques.
Quality control (the inspection of parts and products for defects at different stages of production) and quality assurance (the prevention of defects from monitoring and refining manufacturing processes) have both been improved by the amount of data that can be collected and analyzed along the assembly line of a digital factory. That type of data-based process refinement is important for household appliance manufacturing as modern smart appliances have joined the Internet of Things (IoT) by adding features like network connectivity, remote control, automated functions, smart energy efficiency, and more.
Using Autodesk CAD and CAM software for household appliance design and manufacturing can speed up the design and make processes while saving costs, improving quality, and more:
When using CAD product design software for appliances, designers can catch flaws early in the product development process, reducing the need for multiple physical prototypes, as well as finding ways to reduce material use or find lower-cost material options.
Equipped with CAD consumer products software, appliance designers can quickly revise and iterate on their designs with more streamlined workflows across product development stages. Autodesk software includes intelligent systems for automating tedious workflows and continually adds new options so designers and engineers can accelerate product development.
Cloud-connected CAD software from Autodesk centralizes all design data in a single source of truth so that household appliance design and engineering teams can better integrate their work from any location and effectively make better decisions based on information updated in real time.
Advanced CAD software for appliances is highly precise and accurate in its modeling, increasing part and product reliability by reducing assembly and functionality errors.
Appliance designers using Autodesk Fusion get an integrated CAD and CAM solution in one place. They can use Fusion’s 3D models directly to set up fabrication on machines like 3D printers and CNC machines, seamlessly moving from design to rapid prototyping, and saving time with features like automatic toolpaths and automatic data translation.
The simulation and visualization in Autodesk CAD software grants powerful capabilities and reduces the need for physical prototypes and models. Simulation provides effective virtual testing to evaluate 3D models for performance before moving to prototyping. Detailed 3D visualization provides comprehensive product views that more accurately convey design intent for the form and function of household appliances.
The future of household appliance design and manufacturing can already be seen in the most innovative present-day trends. For example, smart appliances that optimize for energy efficiency have existed for many years, but sophisticated data analysis and processing make today’s smart appliances much more intelligent. They can adjust cycles of energy use based on the owner’s usage patterns to save energy overall. More smart appliances are also joining the IoT and becoming part of a larger connected home network, allowing appliances to be controlled remotely and be part of home automation routines. With their various sensors and networking abilities, smart appliances can offer features like remote-controlled oven preheating or a refrigerator that alerts the user when it’s low on certain items.
More household appliance designers are also designing for disassembly. This added emphasis on appliances’ end-of-life indicates the growing effort to make appliances and their components more reusable and recyclable. The eventual goal is to reach full recyclability and make appliances part of a sustainable, circular economy.
Household appliance manufacturing has also become more focused on sustainability by adding more environmentally friendly materials, such as recycled metals, plastics, and other materials, and by adding more biodegradable materials as well. Appliance manufacturers are making production more energy-efficient and less wasteful by using more renewable energy and optimizing processes through continuous data analysis.

CAD software may offer product designers high-end visualization features, as well as simulations that put product designs through virtual testing before moving to physical prototyping. This can help catch design flaws early in the process, saving prototyping costs by correcting flaws before manufacturing. CAD software like Autodesk Fusion makes it easy to collaborate with others remotely due to real-time cloud connectivity. And Fusion’s integrated CAM features enable prepping for manufacturing on CNC machines, 3D printers, and other machines.
There are many common materials used in household appliances for their specific properties. Metals like stainless steel and aluminum are used for their durability and resistance to corrosion. Different types of plastics are used for strength combined with flexibility and resistance to impacts or chemicals.
Glass and ceramics both offer high heat resistance. Rubber is popular for gaskets, hoses, and other areas where an air- and water-tight seal is needed. Composites, such as fiberglass, are chosen for their combination of strength and light weight.
Smart appliances differ from traditional ones in many ways. For starters, smart appliances are usually IoT devices connected to the Internet, which lets them communicate with other systems and be controlled remotely by the user from a smartphone or by a connected home system that shuts appliances off when the user leaves the house.
Also, smart appliances can automate tasks, like adjusting settings for energy efficiency or starting a cycle when energy rates are lower. They have software that can be updated over the air, granting new features or performance improvements. Other smart features include maintenance alerts and voice control.
Consumer products software helps improve the quality assurance (QA) of household appliances and other goods in many ways. For example, software can automate the repetitive processes of stress tests and other types of tests to mitigate human error. Virtual testing can occur within simulation software before manufacturing prototypes or final designs.
QA software can also collect and analyze different data sets throughout the product lifecycle, such as identifying patterns and anomalies that could cause problems during manufacturing, analyzing customer feedback to find areas for improvement, and gathering IoT sensor data to monitor the performance of a device’s functionality.
