Modular Product Architecture

Modular Product Architecture is a engineering topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Modular Product Architecture rather than just read about it. In short: A Modular Product Architecture is a product design practice, using principles of modularity. In short, a Modular Product Architecture can be defined as a collection of modules with unique functions and strategies, protected by interfaces to deliver an evolving family of market-driven products.

Key takeaways

Modular Product Architecture belongs to engineering; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Modular Product Architecture to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Modular Product Architecture from memory before moving on to harder problems.

Reference excerpt

A Modular Product Architecture is a product design practice, using principles of modularity. In short, a Modular Product Architecture can be defined as a collection of modules with unique functions and strategies, protected by interfaces to deliver an evolving family of market-driven products. Karl Ulrich, Professor in Mechanical Engineering, defines a Product Architecture as “(1) the arrangement of functional elements; (2) the mapping from functional elements to physical components; (3) the specification of the interfaces among interacting physical components”. A Modular Product Architecture consists of interchangeable building blocks (modules) that can be combined into a variety of product variants. Assigning strategic intent to each module enables the producing company to connect its business objectives with the design of the product:. This can be done by the use of Module Drivers. The Module Drivers were first defined in 1998 by Gunnar Erixon, PhD in Design Engineering at KTH Royal Institute of Technology, and grouped into Primary and Secondary Module Drivers. The Primary drivers defines the strategy of the module based on its need for development or variance, as follows

Carry Over: Describes a part that is unlikely to undergo any design changes during the life of the Modular Product Architecture. Common Unit: Describes a part that can be used for the entire product assortment or large parts of it. Technical Specification: Describes a part that carries the product's variance and performance properties. Styling: Describes visible parts of the product that represent identity towards the customer. These parts are strongly influenced by trends and are often connected to a brand or trademark. Technology Push: Describes a part that is likely to undergo design changes due to changing demands or technology shifts. Planned Development: Describes a part that the company intends to further develop, for example to better fulfill a customer value or to cut cost. The planned changes are described in the Modular Product Architecture development plan. Using standardized interfaces between the modules enables interchangeability of different variants of modules and ensures that the Modular Product Architecture can be maintained over time. This enables the producing company to continuously update and improve the Modular Product Architecture and respond to changing needs in the market. Modular Product Architectures can be developed by the use of Modular function deployment.

Worked examples

Example 1 — a first encounter with Modular Product Architecture

Start with the simplest possible case. Write down what Modular Product Architecture claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In engineering, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Modular Product Architecture before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Modular Product Architecture ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Modular Product Architecture

In research: Modular Product Architecture appears in engineering research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Modular Product Architecture in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Modular Product Architecture is common in secondary-school and first-year university syllabi. It links to neighbouring topics Modularity, Product development, Systems engineering, so understanding it makes those chapters shorter.
In everyday life: Look for Modular Product Architecture outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
