“…This relativisation to agents is explicit in other models, e.g. in the Functional Representation approach (Chandrasekaran and Josephson 2000). -The ontological distinction between processes and states of affairs recommends separating basic functions from functional operations.…”

“…Chandrasekaran and Josephson discuss a similar kind of function called environment function as effect on environment (the surrounding world of the device) [2]. Some researchers distinguish purpose from function (e.g., [17]), where the purpose represents human-intended goal in the similar sense to this environmental function or interpretational function.…”

“…In the literature, similar concepts are discussed. Chandrasekaran and Josephson use the concept of role as natural (without human's intention) effects on environment (e.g., the role of cloud is to give rain) and define function as "role+intention" [2]. In EPISTLE Framework, the concept of facility is defined as a functional thing, capability to perform a function and a service [28].…”

“…A function of a component embedded in a system explains how it contributes to achieving the system's whole-function in so-called function structure (i.e., "how things work"). Such functional knowledge shows a part of designer's intention of artifacts (so-called design rationale (DR)) [2,16,26].…”

“…Although much research has been conducted on the representation of function in Artificial Intelligence [2,4,8,17,25], engineering design [5,6,18,21] and Value Engineering [20], there is no common definition of the concept of function itself [2,6,26] and semantic constraints are not enough for deriving effective guidelines for consistent annotation. The authors have established an ontological modeling framework for functional knowledge [9][10][11][12].…”

Abstract. This research aims at promoting sharing of knowledge about functionality of artifacts among engineers, which tends to be implicit in practice. In order to provide a conceptual viewpoint for modeling and a controlled vocabulary, we have developed an ontological framework of functional knowledge. This framework has been successfully deployed in a manufacturing company. This paper firstly discusses an ontological definition of the concept of function from a device-centered viewpoint. Then, other types of function are discussed in order to place our definition in the related concepts in the literature. Next, as an application of the ontologies, we propose a metadata schema based on the functional ontologies for functional annotation in the Semantic Web. The functional metadata annotated to technical documents show designers intentions behind the documents and contribute to efficient retrieval of the documents. Moreover, task-oriented transformation and interoperability with other schemata can be realized based on the ontologies.

Towards Purpose to Function Transition: A systematic approach

In the initial stage of design, capturing user's purposes/needs and transforming them into functions is crucial for wider range selection of design solutions. However, few researchers have distinguished the concepts of purpose and function. The purpose to function transition is still largely an experience‐based process by designers in early design stage and there is still lack of formal approaches or any standard in this field. Therefore, this paper firstly provides a philosophical understanding of purpose and function, tries to clarify their differences, and then proposes a scenario‐based systematic approach to facilitate their transition. In this approach, the transition is conceptualized as a stepwise process and scenarios are integrated in such process for elaborating the initial needs. A case study will also be discussed to demonstrate the proposed approach.
