ETM 551 -Product Architecture 1 Product Design & Development Product Architecture ETM 551 -Product Architecture 2 Questions  How would the architecture of the product impact their ability to offer product variety?  What would be the cost implications of different product architectures?  How would the architecture of the product impact their ability to complete the design within 12 monts?  How would the architecture of the product influence their ability to manage the development process? ETM 551 -Product Architecture 3 What is Product Architecture  A product can be thought in both functional and physical terms.  The functional elements are the individual operationsand transformations  The physical elements of a product are the parts, components, and subassemblies  The physical elements of a product are typically organized into several major physical building blocks, called chunks. ETM 551 -Product Architecture 4 What is Product Architecture?  Product architecture is the assignment of the product's functions to physical building blocks or "chunks". Product module module module module module module module module ETM 551 -Product Architecture 5 Modular or integral architecture? 6 Modular product architecture  Each chunk fully embodies one or more product functions.  Interactions between chunks are:  well defined  (typically) fundamental to product's primary functions.  Modular architecture has advantages in simplicity and reusability for a product family or platform. ETM 551 -Product Architecture 7 Modular product architecture  Modular architecture has advantages in simplicity and reusability for a product family or platform. ETM 551 -Product Architecture 8 Platform Architecture of the Sony Walkman ETM 551 -Product Architecture 9 Integral product architecture  Typical functions involve more than one chunk  Typical chunks implement more than one function  Interactions between chunks are ill-defined and may be incidental to product's primary functions.  Integral architecture generally increases performance and reduces costs for any specific product model.

Ex.: Function sharing of BMW transmission chunk ETM 551 -Product Architecture 23 Manufacturability Benefits from: Design- for-manufacturing (DFM) Minimization of parts count through component integration These strategies are best applied at the chunk level ETM 551 -Product Architecture 24 Managing the PD process Detailed design responsibility... outsourced to a supplier ETM 551 -Product Architecture 25 Concepts of integral and modular apply at several levels System Sub-system Component ETM 551 -Product Architecture 26 Product Architecture = Decomposition + Interactions Interactions within chunks Interactions across chunks ETM 551 -Product Architecture 27 Establishing the architecture Create schematic (illustrating product architecture) Cluster... trailer structure wheels transfer loads to road ETM 551 -Product Architecture 11 Modularity Modularity is a relative property Products are rarely strictly modular or integral ETM 551 -Product Architecture 12 Types of modularity Slot-modular architecture Each chunk-to-chunk interface is different from the others Chunks cannot be swapped around ETM 551 -Product Architecture 13 Slot-modular architecture Each... chunks in the product cannot be interchanged (e.g Automobile radio) ETM 551 -Product Architecture 14 Bus-modular architecture Uses a common bus, or similar concept Uses standard chunk-to-bus interfaces ETM 551 -Product Architecture 15 Sectional-modular architecture No common bus or other single element interfacing with all other chunks Uses standard chunk-to-chunk interfaces ETM 551 -Product Architecture... capabilities Ex.: H-P printer Ex.: Spring and shock absorber for rear suspension of BMW motorcycle ETM 551 -Product Architecture 31 Clustering elements (cont) Similarity of design or production technology Location of change Accommodating variety Enabling standardization Portability of interfaces ETM 551 -Product Architecture 32 Cluster Elements into Chunks Enclosure Enclose Printer Print Cartridge Provide... of material Flow of signals or data Connect to Host ETM 551 -Product Architecture 29 Clustering elements Key considerations when clustering elements (of schematic) into chunks include: Geometric integration and precision Ex.: H-P clustering for ink-jet printer calls for cartridge positioning on x-axis and paper positioning on y-axis ETM 551 -Product Architecture 30 Clustering elements (cont) Function .
