A modular design is an approach for product designing which is used to produce a complete product by integrating or combining smaller parts that are independent of each other. With the modular design approach, a complex product (for example, a car) can be broken down or divided into smaller and simpler components that are independently designed and manufactured. Each of these components is then integrated (or assembled) to form the final product.
Through this article, we will answer the frequently asked questions about modular designs:
As mentioned earlier, modular design (or modularity) is an approach used to design various products or applications – by breaking them down into separate or independent parts. These individual parts (for example, a laptop battery) can then be used for the same functionality in different systems or products. Creative leader chooses modular designs for their products because of their many benefits.
Per the basic definition, modular design allows one to customize, reuse, upgrade, or maintain product designs. Additionally, the modular product’s independent parts follow a standard interface to fit into each other as the finished product easily. On the other hand, works with non-modular designs (for example, an electric switch or electronic products) are not easy to customize or maintain.
Modular design is commonly used in various consumer products like cars, smartphones, computers, and televisions. Other modular design examples include software engineering, software product design, and even large websites (with each webpage as an individual component). A famous example of modularity is LEGO. These plastic toys contain elements that can easily be assembled and reused to develop different finished products.
The use of modularity in product design offers multiple benefits, including the following:
Modular design products are easier to customize according to individual customer needs or preferences. For example, if you are looking for a smartphone with better battery life, you can easily include a high-power battery component (built by a third-party manufacturer) into your model.
Modular products, including new ones, are faster to assemble and release. Each modular component is designed, manufactured, and tested separately to save time, and then assembled for the final product.
The use of modularity can reduce product development and testing costs for the manufacturer, all thanks to shorter development cycles and modular components’ reusability. Additionally, large manufacturers can outsource various components to smaller manufacturing firms, thus cutting down their costs.
A modular design architecture, by definition, uses reusable components that can be used in many similar products; this reduces wastage and adds to the product’s overall sustainability.
A modular system design or product can be easily upgraded (for example, for better performance of a smartphone or laptop). In non-modular products, it is harder to achieve incremental upgrades.
Modular design in software engineering works through a modular programming technique that separates the overall functionality of any software product into independent and interchangeable software modules. Each module can be programmed separately and is designed to achieve specific functionality.
What does modular design mean in application programming and how does it benefit the software development process? A modular system can maximize the software developer’s productivity as it simplifies the development of an enterprise-level product with many functionalities. Through modular designs, large and complex projects can be broken down into smaller and more manageable parts – that can be individually developed and integrated into the final product.
Many product manufacturing companies face the challenge of providing multiple varieties of the same product to meet different customer needs. This is particularly relevant in customer-centric industries like automobiles, computers, furniture, and personal devices. The use of modularity (or modular design) in product design has increased in these sectors because it helps reduce product complexity and manufacturing costs.
Each finished product – with modular product design – is divided into many modules, each with independent features and functionalities. With such a modular architecture, changing one (or more) modules does not impact the other modules’ functionality.
Modular design is used to manage complexity. To accomplish this, we must simultaneously reduce the complexity of each module and the overall module-dependency network. The idea is to make the various stages of module development and deployment as simple as possible. This goal can only be achieved with the help of the five elements of modular design.
There is no doubt that modular designs or modularity are popular these days and offer many benefits to both producers and consumers. However, modular systems also depend on smooth compatibility between their modules (or interfaces) to fit into the final product. When individual parts do not fit together perfectly, a modular design fails. For example, modularly designed computers often require advanced configuration skills.
A modular design approach also does not work for every product or product functionality. Products must be modularity designed only after a thorough analysis of the market. For example, a modular rucksack (ideal for casual trips) that can be altered to look like a formal briefcase (suitable for business meetings) may not work in the real world – as this product caters to two different customer personas.
In summary, we hope we’ve helped you understand the definition of modular design, the difference between non-modular & modular designs, and its usage in software development and design.
