Abstract: This work presents use of MFF (Matrix of function and functionality) method in conceptual design

stage. Compared to the morphological matrix, MFF is structured as multidimensional matrix, which according to

mathematical model presented in this work, generates a functional structure as multilayer functional structure.

MFF collects and binds data from the requirement list and transform them into functional requirements. This

matrix transforms functions and functionalities as sets from the functional domain and design elements domain.

MFF model is searching cross-sections (submatrices) of function and functionality sets. Also is presented

application of MFF model in generation of product conceptual variants.

Key words: Conceptual design, Function, Functionality, MFF (Matrix of function and functionality)

INTRODUCTION

Conceptual design phase is initial stage of product design and product development process [1, 2].

Design process in this phase, is usually specified by complexity [3], unpredictability and creativity [4],

which mainly rests on an individual’s intuition that is hard to repeat in creating new product concepts.

During conceptual design there are no geometric dimensions [2], exactly defined product shape,

tolerances and design structure. Initial data are stored in the form of customer requirements, which

need to be transformed into data acceptable to the further design process. These data are not

unambiguous and exact as is the case for data in phase of detailed design. This is the problem of

abstraction in conceptual design, because the input data in this stage are unarranged, complex and for

design process unacceptable.

The problem of transformation customer requirements into functional requirements and mapping of

customer, functional, physical and process domain involves axiomatic design [5-7]. Since the

conceptual design phase connects the customer requirements and the stage of detailed design, it`s aim

is to transform the information and data obtained from the market, into a form that is acceptable for

designers for further guiding of the design process. According to the theory of technical systems [8],

each product represents the use of a function and therefore, it reflects solving initial functional

requirements [9].

In conceptual design, also is important transmission of knowledge, because it is definitely the missing

shackle [10], and it is extremely important to show the models in a practical implementation (e.g.

computer programming environment in stage of conceptual design.

In the conceptual design stage are developed different matrix models, one of them is morphological

box [11]. Matrix is using the intuitive classification of data without a special mathematical model or

solving rules for connection between functional domain (functions) and design elements domain

(technical systems). It is not possible to connect simultaneously customer, functional, physical and

design elements domain. Also is not possible to arrange functions in functional structure. There is no

fundamental principles for a selection the best solutions and design forms.

As a contribution to solving above mentioned problems, a MFF method was developed. This matrix

method transforms customer requirements into the functional requirements. The process of

transformation is mapping of customer domain into the functional domain. With four function

categories, technical systems are described as the part of design elements domain. These technical

systems we cold functionalities. Thus, the connection between functional and design elements domain

is achieved. It is also possible to generate conceptual variants and their functional description in matrix

form.

COMPUTER APPLICATION OF MFF

Figure 3 presents a flow diagram of the MFF application. It is evident that there are two ways of work

with the application. One way is filling the knowledge base, and the other is to use the knowledge base

to create new product concepts. When using the application it is possible simultaneously to use both

modes.

Figure 3. MFF application flow chart

According to the mathematical model, a computer application has been developed (Fig. 4).

Application is divided in six sections. The most important from this standpoint are database and

product structure sections. Inside of this sections we generate a new concepts described with functions

and physical sizes.

Figure 4. MFF application

Process of conceptual design starts with transformation of customer requirements into the functional

requirements through the input list of functions (Fig. 5). Also functionalities stored in application

database, is possible to prepare and edit through the input list of functionalities (Fig. 5).When

functions and functionalities are prepared for conceptual design, through the lists, we put them in MFF

and begin generation of conceptual variants.

Figure 5. Input list of functions and input list of functionalities

FUNCTIONAL AND MATRIX STRUCTURE

Matrix structure is composed of the MFF matrices (Fig. 6). The matrices are organized by levels and

interconnected by binding links for linking towards matrices at the same level and towards matrices at

other levels. For matrix structure generation it is necessary to establish rough functional structure. This

is input in MFF. On the basement of rough functional structure and by means of MFF, designers

search solutions and determine exactly certain functionalities. Rough functional structure, on this way,

is completed and stored as detail functional structure.

Figure 6. Functional and matrix structure of product

Matrix structure for a listed product is generated from the product detailed functional structure. The

total number of matrix structure levels corresponds by analogy to the total number of levels of the

product’s detailed functional structure. In matrix and functional structure is stored design knowledge

for a listed product.

CONCEPT GENERATION BY MFF METHOD

In this chapter is described procedure of generation conceptual variant of assembly Turbo-blower.

This assembly is part of product at a higher hierarchical level-Suction unit. Therefore, Turbo-blower is

a subassembly in Suction unit product shape structure. Concept is determined by function "Negative

pressure generation and fluid flow calming" (Fig. 7). The function is on the second level of the

functional structure of Suction unit. This function is necessary to solve with six partial functions,

which were generated by transformation of selected customer requirements (Fig. 7). Using the input

list of functions, functions are implemented in the matrix.

Depending on the number of functions, arranging process of matrix starts and can be very long,

because involves functional modelling procedure.

In Table 1 are presented functions from input list and accepted functionalities whose functions in

submatrices are solving them. It`s possible to see category of function in submatrix and percentage

value of solution.

CONCLUSION

By analysing matrix methods (especially morphological box) used at the conceptual design stage, the

problem of associating, displaying and transforming of customer requirements into acceptable data for

further guidance of design process was noticed. In order to contribute to the solution of this problem, a

MFF method was developed. Using this model, according to the theory of technical systems and

axiomatic design, binding between customer, functional, physical and design elements domain was

achieved. The mathematical description of the model as well as the developed computer application

are presented in this work.

The beginning of the design process requires a new set of customer requirements. Through the set of

rules, the process of mapping customer requirements into the set of functions represents a

transformation a customer domain into the functional domain. Solutions of a new set of functions are

obtained through the MFF by linking with the functions who describe functionalities. These functions

are divided into the four categories (main, supplementary, auxiliary and binding function). On this

way functionalities are solutions of new set of functions. Every new set of functions represent a new

conceptual variant of new future product.

Also is presented generation of multilayer matrix structure. Inside of this structure is stored a product

functional structure. Possibility of generation functional structure, stored in matrix structure, enable

fully review of data to designer. This data describe product and present design knowledge stored in

MFF.

For further research, it is necessary to develop model who can create weight factors and map them to

evaluation criteria. According to this, it is necessary to upgrade present computer application. On this

way, with this models and this application it will be possible to simulate a creation of new conceptual

variants and also will be possible to simulate a decision making process in conceptual design stage.
