Modular components work together to form a single functioning item, with each part being self-contained but dependent on other components to function. They allow for easy upgrading, changing, or repairing of one component while leaving the core system operational. Modular components differ from interchangeable components in that they perform a complex action beyond what a single interchangeable part can do. When combined, they create a greater whole. Some modular components, such as modular furniture, do not need other pieces to function.
Modular components are items that work together to form a single functioning item. In some cases, the modular piece may have a complete function that it is capable of performing when not connected to any other piece, but this is rare. In most cases, a modular component is totally self-contained, but it also depends on other components to function. When multiple modular components are combined, they create a modular system. Because each part is separate, it is often possible to upgrade, change, or repair one component while leaving the core system operational.
The cornerstone of modular components is the idea of self-containment. Everything the component does is contained within the element itself. The component may need other parts to make its action useful, but these do not directly affect the component. A car engine is a great example of this idea: it’s complete and separate from the car, but without the rest of the parts, it doesn’t actually do anything when it’s running.
This is where modular components differ from interchangeable components. Modular pieces are discrete parts of a system, such as a car engine. A replacement part is an object that has no function until it is placed with other objects, such as a belt inside the engine. If a belt was resting on the ground, it couldn’t actually perform a function without the motor, while the motor could still run.
Another important factor in defining a modular component is in its function. A modular piece will typically perform a complex action beyond what a single interchangeable part can do. Going back to the previous example, a perfectly good engine has many more uses than a single engine belt. Even though the two have been used in places other than inside a car, the possible actions with the engine far outweigh any of its constituent parts.
This feature is usually part of a larger picture. When modular components stand alone, they are rarely useful. When those same components are connected, they will grow larger than any part individually. Each component is still separate and performs a single function, but when all these functions are combined, it creates a greater whole.
While most modular systems are interconnected, not all modular components need other pieces to function, which is the case with modular furniture. While a modular desk may seem strange on its own, it’s still a desk and works just as well as any other desk. When other components are added to the system, such as an additional corner desk or sideboard, the desk looks more correct and works better.
