Effective Design

Engineering educators face a heavy responsibility in equipping young engineers for today's competitive world. The industries that will employ them will only survive if the people working in them are able to make and follow sound decisions. The basis for these decisions, among other things, must be an effective design process. The challenge of educating students to become worthy design engineers is being met at the Mechanical Engineering Department, at BGU, Israel, and the purpose of this article is to describe how it is done.

Design education is a large field. It is not just limited to engineering design but can also include apparel design, industrial design, graphic design, architecture, and many others. These disciplines instruct students to follow a similar design process to what is generally taught in engineering design. However, these other disciplines contain a variety of instructional techniques, class structures, and class types that are not regularly included in engineering design. While design engineers tend to get a background rich in math and science, instructing students in design can be difficult. Many of these math and science classes focus on one approach and one right answer. However, in design the answers tend to fall on a spectrum from unsatisfactory to varying levels of satisfactory to ideal and innovative solutions, all of which can be uncovered using widely varying design methods. Despite the rigidness of the mechanical engineering curriculum there are areas where the implementation of techniques used in the other design disciplines could be advantageous to help engineering design students improve students design skills, design process knowledge, and softer skills such as team communication. The research done in this paper examines how the curricula of design disciplines could influence the coursework of students focusing on the design area of mechanical engineering.

Abstract Mechatronics is the synergistic combination of precision mechanical engineering, electronics, control engineering, and computer science in the design process. This paper describes a new elective course entitled Mechatronics which has been developed and was taught for the first time at Rensselaer during the fall 1991 semester to 45 senior-undergraduate and graduate students. The key areas of mechatronics which are studied in depth in this course are: control sensors and actuators, interfacing sensors and actuators to a microcomputer, discrete controller design, and real-time programming for control using the C programming language. The course is heavily laboratory-based with a two-hour laboratory weekly in addition to three hours of classroom lecture. The laboratory exercises include computer-aided control system design using MATRIXx, various analog and digital sensors, hydraulic actuators, DC and stepper motors, and computer control of a variety of physical systems. The unifying theme for the course is the integration of these key areas into a successful mechatronic design. Students are required, as a final project, to: identify a problem or need, analyze the problem, and write a problem statement; perform a state-of-the-art review; develop a list of specifications and identify the key specifications; generate an outstanding mechatronic-system conceptual design; and finally perform a detailed design of the system which may include model building and hardware development. Examples of student projects are described. This course should significantly enhance our design education program in the Mechanical Engineering Department and lay the foundation for the students to become mechatronic design engineers.

Just as design is a fundamental part of engineering work, prototyping is an essential part of the design process. For many engineering design courses, students must develop a final prototype as part of the course requirements. And in industry, engineers build multiple prototypes when creating a product for market. Although prototyping is core to design education, there is a lack of research on understanding the perceptions and usage of prototypes from both students and professionals. Without understanding students’ perceptions of prototypes, we cannot adequately train them. Likewise, without knowing how professionals use prototypes, we cannot translate these practices back to design education. This paper reports on the pilot study comparing the perceptions of prototypes between mechanical engineering students and professional engineers. The findings indicate that the interpretation of the term “prototype” varies between students and professionals. Specifically, these mechanical engineering students have a more narrow perception and identify prototypes as only having a few key elements, namely for building and testing functionality and feasibility of physical elements in a product. Comparatively, professionals have a broad perception of prototypes. They identify a wider range of attributes, including prototypes as a communication tool, an aid in making decisions, and a way to learn about unknowns throughout the design process. Many instructors in design education are cognizant of the importance of prototyping. However, we believe that students require explicit instruction about key concepts. It is not enough to just tell students to “prototype.” As design educators, we must be aware of the various roles of prototypes, and teach these concepts to students. We provide some immediate recommendations for practice, including a list of ten principles of prototypes to create similar mental models between students.

Queen’s University at Kingston has been graduating a unique breed of multidisciplinary engineer since 1994: the Mine-Mechanical option students within the Queen’s Mining program are exposed to the fundamentals of both Mechanical Engineering and Mining Engineering. The final year capstone engineering design project in the Mine-Mechanical option focuses on mining equipment design, and since 2000 this multidisciplinary project has been carried out in collaboration with Sandvik Mining and Construction of Burlington, Ontario. The students work on real world design projects formulated by design engineers at Sandvik, under close communication and coordination with academic project advisors. These design projects are differentiated from typical mechanical engineering design projects in that they require a thorough understanding of the mining context in which the equipment is to be deployed and operated. This paper will present the structure and format of this university-industry educational collaboration, review past successes, evaluate the educational outcomes as well as benefits to industry, and ponder some lessons learnt.

Engineering design is becoming an integral part of any engineering program seeking international recognition and accreditation. Design practices are becoming a necessary experience to senior students nowadays in all engineering programs. The final year design project offered at Sultan Qaboos University in Oman gives senior students the chance to integrate their knowledge accumulated through already taken courses in the Mechanical Engineering Department to design particular products, experiments, and/or mechanical systems. In addition to gaining hands on experience of the design process, students were able to develop their communication skills and team work spirit. Throughout the whole year, students knowledge and expertise are enhanced through direct contact with their project advisor(s), project related memos, oral presentations, memos, posters, and written progress and final reports. The present paper describes the design process followed by a group of three senior students starting from understanding the problem and developing conceptual designs to the end product. CAD tools such as AutoCAD and ABAQUS were used to complete the design, build a prototype, and test it.

History Of

The “Warman Design and Build Competition”, running across Australasian Universities, is now in its 26th year in 2013. Presented in this paper is a brief history of the competition, documenting the objectives, yearly scenarios, key contributors and champion Universities since its beginning in 1988. Assuming the competition has reached the majority of mechanical and related discipline engineering students in that time, it is fair to say that this competition, as a vehicle of the National Committee on Engineering Design, has served to shape Australasian engineering education in an enduring way. The philosophy of the Warman Design and Build Competition and some of the challenges of running it are described in this perspective by its coordinator since 2003. In particular, the need is for the competition to work effectively across a wide range of student group ability. Not every group engaging with the competition will be competitive nationally, yet all should learn positively from the experience. Reported also in this paper is the collective feedback from the campus organizers in respect to their use of the competition as an educational experience in their classrooms. Each University participating uses the competition differently with respect to student assessment and the support students receive. However, all academic campus organizer responses suggest that the competition supports their own and their institutional learning objectives very well. While the project scenarios have varied widely over the years, the intent to challenge 2nd year university (predominantly mechanical) engineering students with an open-ended statement of requirements in a practical and experiential exercise has been a constant. Students are faced with understanding their opportunity and their client’s value system as expressed in a scoring algorithm. They are required to conceive, construct and demonstrate their device with limited prior knowledge and experience, and the learning outcomes clearly impact their appreciation for teamwork, leadership and product realization.

Thermoacoustic Oscillations

Six burner/furnace systems which operated successfully without vibration are evaluated for resistance to thermoacoustic oscillations. The evaluation is based on the Rijke and Sondhauss models representing the combined burner/furnace (cold/hot) thermoacoustic systems. Frequency differences between the lowest vulnerable furnace acoustic frequencies in the burner axial direction and those of the systems’ Rijke and Sondhauss frequencies are evaluated to check for resonances. Most importantly, the stability of the Rijke and Sondhauss models is checked against the published design stability diagram of Eisinger [1] and Eisinger and Sullivan [2]. It is shown that the resistance to thermoacoustic oscillations is adequately defined by the published design stability diagram to which the evaluated cases generally adhere. Once the system falls into the stable range, the frequency differences or resonances appear to play only a secondary role. It is concluded, however, that in conjunction with stability, the primary criterion, sufficient frequency separations shall also be maintained in the design process to preclude resonances. The paper provides sufficient details to aid the design engineers.

"The use of VR technology within education is an area that has generated great interest in recent years, so this work follows that trend and contains nuances related to user-centred design education. The objective of this work is to identify students’ perceptions of the use of VR technology for ethnographic research. A group of 20 industrial design students from Tecnologico de Monterrey conducted a field investigation, which included interviews and surveys, using HMD with videos and stereoscopic images of a public park in Monterrey, Mexico. Based on the research and information analysis, areas of opportunity were identified and urban furniture proposals for the public park that place were generated. Once the design process was completed, an evaluation instrument was applied to measure, through statistical analysis, the students' perceptions of their experience using technology in the design process; gender, qualification obtained and the relevance of the technology used was also considered."

Undergraduate Thesis

This presentation, reflecting a politics undergraduate thesis, will explore the design process behind the ballots that voters use in democratic elections around the world. Ballots are an inherently political objects, and in many cases, the most direct line of communication a citizen has to the government of their country. As such, the design of the ballot affects the legitimacy of higher level electoral and democratic institutions. This project argues that by co-opting the language of product design, a universal ballot design process would make more efficient ballots across the globe.   Product design starts with a brainstorming stage that explores at the user, the goal of the object, and the context of its use to create an effective design. By applying these observations to the process of designing a ballot, each electoral commission can produce a more effective ballot. Currently there is no standardization for ballot design other than ensuring that electoral commissions tried to make it “friendly.” By examining cases of bad ballot design, it is possible to see what element of the design process was missed or misused to create a process that corrects for these mistakes. This project examines poorly designed ballots in Florida, Scotland, and Colombia to explore the large-scale effects these small design choices make, and how to fix them.

ABSTRACT This study aims at presenting the process of machine design and agricultural implements by means of a reference model, formulated with the purpose of explaining the development activities of new products, serving as a guideline to coach human resources and to assist in formalizing the process in small and medium-sized businesses (SMB), i.e. up to 500 employees. The methodology used included the process modeling, carried out from case studies in the SMB, and the study of reference models in literature. The modeling formalism used was based on the IDEF0 standard, which identifies the dimensions required for the model detailing: input information; activities; tasks; knowledge domains; mechanisms; controls and information produced. These dimensions were organized in spreadsheets and graphs. As a result, a reference model with 27 activities and 71 tasks was obtained, distributed over four phases of the design process. The evaluation of the model was carried out by the companies participating in the case studies and by experts, who concluded that the model explains the actions needed to develop new products in SMB.
