This paper presents a case study on the mechanical design and fabrication of the Pico Radio Test Bed: a wireless networking node for experimentation with applications, networking, media access layer design, and position locating algorithms. Particular focus is placed on the systematic design process and resolving coupling design constraints between the mechanical and electrical domains. Three generations of the design are presented to demonstrate the evolution of the design as conflicts arose, problems were noticed, and requirements changed.

Design Process Model

Background: In the whole design process of modular fuel tank, there are some unreasonable phenomena. As a result, there are some defects in the design of modular fuel tank, and the function does not meet the requirements in advance. This paper studies this problem. Objective: Through on-the-spot investigation of the factory, a mechanical design process model is designed. The model can provide reference for product design participants on product design time and design quality, and can effectively solve the problem of low product design quality caused by unreasonable product design time arrangement. Methods: After sorting out the data from the factory investigation, computer software is used to program, simulate the information input of mechanical design process, and the final reference value is got. Results: This mechanical design process model is used to guide the design and production of a new project, nearly 3 months ahead of the original project completion time. Conclusion: This mechanical design process model can effectively guide the product design process, which is of great significance to the whole mechanical design field.

Students learning design engineering at times need a good example of procedure for novel design engineering. The systematic heuristic-strategic use of a theory to guide the design process – Engineering Design Science – and the methodical design process followed in this case study is only necessary in limited situations. The full procedure should be learned, such that the student can select appropriate parts for other applications. Creativity is usually characterized by a wide search for solutions, especially those that are innovative. The search can be helped by this systematic and methodical approach. This case example is presented to show application of the recommended method, and the expected scope of the output, with emphasis on the stages of conceptualizing. The case follows a novel design problem of a mechanism to open and close the bow thruster covers for the Caravan Stage Barge.

Abstract Many designs fail because one or more checks are not done, or are done too late during the design process. A functional modelling system is presented, which provides systematic design checking at early design phases by means of constraint satisfaction. However, problems can occur if the design to be checked involves too many constraints. This paper presents some extended research, which establishes a knowledge hierarchy for managing the mathematical constraints, so that the computer can process large designs. A case study of fastening joint design using this hierarchy is discussed.

The Relationship

This article compares and contrasts the use of haptic and digital sketching in the design process. It investigates the preferred sketching method of final year design students. In addition, it examines the relationship between effective communication and the use of haptic and digital sketching. A case study involving ten final year students studying product design courses at Nottingham Trent University was undertaken. The text explores the current literature and identifies the benefits of using the two methods. The inclusion of digital sketching tutorials in the undergraduate curriculum is discussed as well as the option of replacing haptic with digital sketching. The study concludes that while a wider survey with students from other design courses would be useful, the results provide strong evidence that final year students currently prefer haptic to digital sketching as an essential part of the design process.

Design Process Model

The emergence of computer and network technology has provided opportunities for researchers to construct and build systems to support dynamic, real-time, and collaborative engineering design in a concurrent manner. This paper provides an understanding of the product design in a distributed environment where designers are in different geographic locations and are required to be involved in the design process to ensure successful product design. A design process model that captures the major interactions among stakeholders is presented, based on the observation of cooperation and collaboration. The stakeholders’ interactions are divided into activity and system level to distinguish the interactions in group design activities and design perspective evolution. An initial computer implementation of the design model is presented. The design system consists of a set of tools associated with design and a management system to facilitate distributed designers to support various design activities, especially conceptual design. Our research emphasis of design collaboration in this paper is: (i) Model a Cooperative-collaborative design process; (ii) Support synchronized design activities; and (iii) Structure the complex relations of various design perspectives from engineering disciplines.

Characteristics Analysis

In conceptual mechanical design process, designers sometimes focus their attentions on mapping a sub-function or functional unit to a single mechanism or system, and ignore the interfaces among the structural elements. This paper first summarized the behavioral characteristic of the interfaces in energy, mechanics, kinematics by analyzing the roles, classification and connection styles of such interfaces. Subsequently, it introduced the concepts of function and free surface, and gave the interface design process. Finally, a case study was conducted to demonstrate the feasibility of the proposed methodologies.

Theoretical Approaches

This paper aims to establish a theoretical foundation for representing and interpreting free-hand design sketches throughout the conceptual design process. Both experimental and theoretical approaches are used. In using the experimental approach, one case study from a book and one case study from an automobile assembly system manufacturer are used to illustrate the characteristics of design sketches. These characteristics provide the requirements for models of sketch representation and interpretation. In using the theoretical approach, a mathematical structure of design sketches is established. This mathematical structure can naturally and logically model the evolving sketches generated in the design process, through integrating the strengths of set theory and mereology. Based on the results of these two approaches, a design sketch language is developed to be a formal foundation of sketch representation and interpretation.

Functional Concept

Cross-disciplinary technologies are noticeable phenomena in modern products, as found in renewable energy and electric vehicle industries. However, current conceptual design tools have been limited to respond these cross-disciplinary technology products. One of remarkable characteristics in this technology change is transforming an existing product with multiple cross-disciplinary technologies. This paper presents a new product design paradigm, called Transformative Product Design (TPD), to respond this phenomenon. In TPD, transformation is a design process to produce a new product (i.e., transformative product) from a base product by adding and/or converting functions/features with reference products or technologies. To accomplish the transformation process, this paper develops a new Functional Concept-based Detection method. Also, the proposed functional concept-based detection method is described with a case study in the context of transformative product design process.
