Machine Elements

The Design of Machine Elements course is one of the most difficult and complicated courses in the Mechanical Engineering program. It requires inventive concept generation, the knowledge of geometrical design, and basic knowledge of stress and deformation analyses. On those three elements, the machine elements design philosophy is established and further developed. The course material has to be chosen carefully since the time constrains will allow to cover design of only few essential machine elements. The material is covered by lectures, textbook readings, homework problems, and design projects. In addition to the textbook content the course contains five special elements: Idea Generation, Safety Considerations, Design of the Day (DoD), a Designer’s Liability study, and three projects including Final Project – Shaft Design. In the Idea Generation project, students generate an idea of machine or mechanical device. The Safety Consideration project is done by inspection and documentation of unsafe elements on campus. The Shaft Design Project had students design a shaft system under given constrains. In DoD students present existing advanced machines chosen using different sources or their own industrial internship experience. The Liability assignment addresses the designer’s legal responsibility in case of a defective product that caused an injury or accident. The material taught in the course is larger than conventional machine element design course. The elements added that are beyond the structural analysis bring better understanding of engineering problems during the Senior Design course and later during engineering practice. They allow the students to connect the theory with the real world of engineering challenges. This gives students more satisfaction during the learning process and cognitive benefits during engineering practice. The unconventional inventive design approach of the teaching team (course instructor and GTA) to problem solving is based on many years of instructor’s experience in teaching of engineering problem solving and design. The learning pattern in which students work in teams, both in problem solving and in design exercises, also helps to conduct the course. Thanks to all these elements the learning experience of the course is unique and engaging despite the high level of difficulty associated with it.

Nowadays parts made of up-to-date engineering plastics are used more and morein mechanical engineering practice. These machine-elements are produced most frequentlyby injection molding or by one cutting process. The injection molding technology are usedgenerally for great number of pieces, in case of serial production while cutting processes arepreferred to piece (unit) or smaller number production.We used lathe and measured the main- and feeding-directional cutting force at differentengineering polymers (cast PA6, POM C and UHMW PE HD 1000). The analysis made canbe well used in practice.

GUY’s forceful personality and abounding energy were a source of continual wonder and inspiration to his staff throughout his time as turbine designer. But he drove himself too hard; these great gifts were beginning to fail in the last phase of his career. In Guy’s boyhood locomotive work was the field most clearly offering scope for talent in mechanical engineering. Guy trained as a pupil under the Chief Mechanical Engineer of the Taff Vale Railway. He received his technical education at the University College of South Wales from 1907 to 1910. He was a hard worker and academically brilliant. He obtained the college diplomas in Mechanical and Electrical Engineering. He did not take a degree as he had not matriculated. In later life the honorary degree of D.Sc. was conferred on him by the University of Wales.

It is common for engineers but rare for engineering students to be asked to work on projects with people whose expertise is in other fields. In an effort to address this shortcoming at the University of Dayton, an interdisciplinary mechatronics class was developed. This lab based course with equal numbers of electrical engineering and mechanical engineering seniors focused on designing, building and controlling electromechanical systems. This paper covers the development of the course and the challenges posed in teaching such a course. The course is centered on the concept of building an autonomous system by integrating a well designed mechanism with a well designed electrical controller. Particular emphasis is placed on the challenge of covering material which is basic and familiar to one set of students while being novel and challenging to another set of students. Additional discussion is included on encouraging cross-disciplinary communication, preventing asymmetrical workloads and stimulating innovation.

Engineering Problem Solving

The Engineering Problem Solving process has two aspects. It relies on the talent of the designer on the one hand and the efficiency of the problem solving tools on the other. Talent is an attribute of a person. It is very difficult to formalize the talent of an individual, and no satisfactory formalization has been achieved successfully. For this reason only the original designer’s talent and his/her knowledge and experience are available for use during the problem solving process. However, there are several choices and decisions that can be made concerning methods, algorithms, and software packages. After those choices are made the next steps in the problem solving process can be outlined. The problem solving method described in this paper is called a Brief Theory of Inventive Problem Solving (BTIPS) and was developed on the basis of TRIZ (Russian: теория решения изобретательских задач, teoriya resheniya izobretatelskikh zadatch) and TIPS (Theory of Inventive Problem Solving) and taught at the University of Connecticut (UConn). The application of this method starts with the accurate definition of the problem. The problem has to be properly separated from the environment. Further problem solving choices depend on the knowledge of the designer and include the right sequence of steps, definition of contradictions, choice of solution modules, algorithms, definition of designed systems and subsystems, and choice of elements and objects. There are several further paths to be selected and resulting decisions to be made. Those decisions and the processes following them are described in this paper. The recommendations for the proper path are given and the procedures are discussed. The derivation of the Ideal Solution is described and tests of the solution’s effectiveness and economy are given. The experience gained from teaching one Mechanical Engineering course, three MEM (Management Engineering for Manufacturing) courses at UConn, one graduate course at UConn, one graduate course at the University of Fairfield, and several special non-academic courses for practicing engineers is summarized. Some students’ opinions are analyzed and recommendations for further education and the practice of engineering problem solving are derived. The references to the existing teaching, research, practice, and development studies are quoted. This paper is devoted to the characteristics of BTIPS method. The companion paper [1] is devoted to the characteristics of the software that could be used with the method. TIPS (the Theory of Inventive Problem Solving) is a further development of Altshuller’s theory done by Invention Machine under the leadership of Valery Tsourikov [2]. BTIPS (Brief Theory of Inventive Problem Solving) is a simplified version of TIPS developed at the University of Connecticut (UConn) especially for teaching purposes, though it is also powerful when applied to engineering practice problems [3].

Design Experience

Design activity is core to modern engineering practice. Some design experience is demanded by professional bodies that accredit degree engineering programmes (e.g. ABET and ECSA). The purpose of this paper is to track design related topics through the curriculum of the mechanical engineering degree programme at the University of Botswana. A questionnaire was designed and administered to staff teaching on the programme. The responses were used to map design components in the curriculum and assess the design experience of students. The results showed that design topics were delivered in various courses and the knowledge gained by students increased steadily from Year 3 to Year 5. Some observed deficiencies in the teaching of design included lack of industry recommended projects, negligible application of design software, and the use of only single discipline based problems (i.e. no multi disciplinary teaching approach). It was concluded that a programme review is needed to improve the pedagogy of design and enhance programme robustness. It is envisaged that the study will help in designing a new mechanical engineering curriculum to satisfy accreditation requirements.
