Port-Based Description of Functional Modeling for Product Conceptual Design

Abstract

This paper introduces an approach to a port-based functional modeling framework for product conceptual design. A port-based knowledge building process is described for functional modeling. This research proposes a method of creating and managing different ports. First, this paper describes port attributes and three port types -mechanical port, electrical port and configuration port, and gives port attributes of compatibility. Second, it presents a port-based modeling design process, that is divided into three main modules: the language of port description, port-based FBS representation and port knowledge management. Three knowledge layers are specialized for function, behavior and structural knowledge. They represent different abstraction levels of the product conceptualization. Each layer is represented with a description logic for convenient reasoning. We provide formal definitions of the framework to manage port knowledge. Finally, the process of port-based functional modeling is presented in a thermal bubble jet application to demonstrate the effectiveness of the research.

Physical Realizations: Transforming into Physical Embodiments of Concepts in the Design of Mechanical Movements

“…We, therefore, need to address the question of how to reason about suitable interfaces for connecting two physical objects, each of which represents a spatial element at the physical level. As reported in previous studies [17,18] to derive types of contact (e.g., point contact or line contact). However, the major difference of this previous approach to the one proposed in this paper is as follows: while earlier work [17,18] describes how an interface is to be connected (e.g., line contact), our proposed method proposes that, in addition to the type of contact needed, a physical interface should include information on the interface shape (e.g., groove) and the position of the contact point.…”

The range of physical elements of a specific spatial element would affect the variety of physical objects, while the type of spatial elements would decide the variety of the space of abstract solutions.…”

Multi-Sensor Fusion of the Foreleg Mechanism for Wheelchair Climbing-Stairs

“…These ranges accordingly limit the foreleg mechanism motion as shown in Figure 1. Thus, the foreleg act needs to meet the following requirements [4].…”

A Transdermal Miniature Syringe Design Based on Port Ontology for Drug Delivery

“…Therefore, the miniature syringe can be seen as the ontology and its port, as shown in Fig. 2, should satisfy with design requirements listed as follows [5].…”
