A Function Structure Diagrams (FSD) is a graphical representation of the functions a product performs on its inputs and outputs. In a FSD, the overall function is broken down into elemental or atomic sub-functions. Each sub-funtion can not be broken down further and is solution neutral.

A function structure is an abstract model of the new product, without material features such as shape, dimensions and materials of the parts. It describes the functions of the product and its parts and indicates the mutual relations.

Functional Analysis as the systematic process of identifying, describing, and relating the functions a system has to be able to perform, in order to be successful, but does not consider it as a design tool to address how functions will be performed, i.e. to map functions to physical components.

In order to apply morphological analysis to product design, we simply identify the critical functions in our function structure diagram and then identify many different solutions for each function. The results of this research are compiled and presented in morphological chart.

♦ Describe, and illustrate with examples, two tools of functional analysis - Functional Flow Block Diagrams and Time Line Analysis. ♦ Functional analysis is the systematic process of identifying, describing, and relating the functions a system must perform in order to to be successful. It does not address how these functions will be performed.

May 14, 2018 · The document discusses establishing functional structures through function analysis for engineering design. It defines functions as the purposive actions a product is meant to perform. The key steps are: 1) Expressing the overall function in terms of inputs and outputs. 2) Breaking this down into essential sub-functions.

... electromechanical systems, an effective functional modeling method is the function structure ( Pahl and Beitz, 1988), which connects sub-functions with flows of energy, material, and...

It is this latter “formal structure” of the parts and their place in a hierarchy of wholes that participants in design work to define (in full, i.e., all relevant parameters specified), given the stated functional requirements of the parts of the whole.

Propose a new methodology for identifying necessary functions based on Function and Behavior Representation Language (FBRL), and a method to use the functional diagram. The result of this...

Idea generation is accomplished by creating single systems from different mechanisms illustrated in the morphological chart. It is advised to generate several feasible designs using different mechanisms for each function for each concept.
