Functional Platform Architecture In Product Design

slide-37
SLIDE 37

Definition: “Functional Platform”

Functional Platform Architecture in Product Design

  • A discrete functional element of a composite and/or

complex system that provides a specific contribution to the whole system

slide-38
SLIDE 38

Functional Platform Architecture in Product Design

  • Aphorisms* procedural steps in architecture

development or product design analysis

* Aphorisms: concise statement of principle

Source: Rules and Methods

slide-39
SLIDE 39

Procedural Steps in Architecture Analysis or Development

Aphorisms and Procedural Steps in Architecture Development or Product Design Analysis

  • Strive to design interface architecture that is elegantly

simple, reliable, cost effective, and will be a long lived design architecture. A “standard” geometry that could persist for years. (Example: 35mm film cartridges, electric

  • utlets, lamp sockets, telephone jacks, QWERTY keyboard.)
  • Avoid “domino effect” of functional element platform designs
  • r evolutionary changes that violate interface architecture.

Platform designs should not bridge or leak to other platforms across interfaces.

slide-40
SLIDE 40

Procedural Steps in Architecture Analysis or Development

Aphorisms and Procedural Steps in Architecture Development or Product Design Analysis

  • Isolate and reduce each functional element of the

total system to a singular function

  • Identify and specify each interface (linkage),

essential and nonessential, of each functional element to another

slide-41
SLIDE 41

Procedural Steps in Architecture Analysis or Development

Aphorisms and Procedural Steps in Architecture Development or Product Design Analysis

  • Decouple as many interfaces as possible - strive to

max out at two (2) interfaces. (Avoid complexities

  • f four (4) or more interfaces.)

Procedural Steps in Architecture Analysis or Development

Aphorisms and Procedural Steps in Architecture Development or Product Design Analysis

  • When a functional platform transitions from “generic” to a

“unique” state, restrict functional platform architecture to two (2) interfaces: one (1) generic and one (1) unique interface. (Avoid coupling multiple functional architectures to unique systems.)

  • Within each functional platform architecture allow for many

degrees of freedom and latitude, i.e. capability, variety of functions, materials, hierarchy of capability, etc.

Procedural Steps in Architecture Analysis or Development

Aphorisms and Procedural Steps in Architecture Development or Product Design Analysis

  • At end user interfaces, provide architectures to enable a rich

variety of capabilities, forms, visuals, and features for the product’s evolutionary life cycle extensions, competitive advantages, and future product line developments and multiple product platforms.
