Powder bed fusion (PBF) additive manufacturing (AM) provides a great level of flexibility in the design-driven build of metal products. However, the more complex the design, the more difficult it becomes to control the quality of AM builds. The quality challenge persistently hampers the widespread application of AM technology. Advanced imaging (e.g., X-ray computed tomography scans and high-resolution optical images) has been increasingly explored to enhance the visibility of information and improve the AM quality control. Realizing the full potential of imaging data depends on the advent of information processing methodologies for the analysis of design-quality interactions. This paper presents …

Searching for information and using that information appropriately is an essential part of every engineering design project. It has been reported that design engineers spend about 30% of their time searching for information. Experience shows that even senior level students have not received proper training, either directly or indirectly, in information literacy (IL). They usually search for information intuitively. For mechanical and aerospace engineering students at West Virginia University Institute of Technology (WVU Tech), the Mechanical Engineering System Design I and II courses (MAE 480 and 481) are probably the last chance to teach students about IL. In this project, …

Engineering design has transformed significantly due to advances in embedded system design and computer technologies. Almost every mechanical design today has some electrical and electronic components. Many products manufactured today contain both electrical and mechanical components and systems. Mechatronics is a design process that is multi-disciplinary in nature and integrates principles of many engineering disciplines including, but not limited to, mechanical engineering and mechanical engineering technology, electrical engineering and electrical engineering technology, and controls engineering. Mechatronic systems can be found in many different places today. These range from computer hard drives and robotic assembly systems, to washing machines, coffee makers, …
A Study On The Role Of Physical Models In The Mitigation Of Design Fixation, Vimal Viswanathan, Olufunmilola Atilola, Nicole Esposito, Julie Linsey
A Study On The Role Of Physical Models In The Mitigation Of Design Fixation, Vimal Viswanathan, Olufunmilola Atilola, Nicole Esposito, Julie Linsey
Faculty Publications, Mechanical Engineering
Designers implement a variety of models and representations during the design process, yet little is known about the cognitive impacts of various representations. This study focuses on how physical models can assist novices in mitigating design fixation on undesirable features. During idea generation, designers tend to fixate on examples they encounter or on their own initial ideas. The first hypothesis states that designers tend to duplicate features of provided examples. The second hypothesis states that this fixation can be mitigated with appropriate warnings. The last hypothesis is that building and testing physical models can help designers in mitigating fixation. To …
Measuring The Impact Of Internships On Design Using A Materials Activity, Craig Johnson, Charles O. Pringle, Nathan Davis
Measuring The Impact Of Internships On Design Using A Materials Activity, Craig Johnson, Charles O. Pringle, Nathan Davis
Engineering Technologies, Safety, and Construction Faculty Scholarship
Our research question focused on how previous student experience, like a job internship, affects an ability to demonstrate engineering design skills. Principal student experience focused on prior industrial experience (e.g. internships), but also included annual project participation (e.g. ASME Design Challenge Teams). The scope of this effort included the creation and application of a design activity, resulting in documents that were evaluated with a metric. The activity focused on the effect of material selection and analysis with regard to ‘design performance’. Creating these activities, and using them to assess design skills is the novel aspect of this effort. Two classes …
Languages For Engineering Design: Empirical Constructs For Representing Objects And Articulating Processes, Clive L. Dym, Philip Brey
Languages For Engineering Design: Empirical Constructs For Representing Objects And Articulating Processes, Clive L. Dym, Philip Brey

Design knowledge incorporates knowledge and information about designed objects and their attributes, as well as about methods and means for undertaking the design process. Such design knowledge is articulated in several different representations or languages. This paper presents a typology of the languages of engineering design, emphasizing the representation of designed objects and the articulation and representation of the cognitive processes of design. Design languages include verbal or textual statements, drawings and graphics, formulas, and numbers. Still other design languages follow from computational styles. The languages of design and their computer-based implementations are empirical in origin, since observation reveals that …

Design And Design Centers In Engineering Education, Clive L. Dym
All HMC Faculty Publications and Research
This paper is intended to be the opening salvo of the workshop, Computing Futures in Engineering Design (Dym, 1997). Thus, I want to take this privileged moment to ask you to think with me about the role of design in engineering. In particular, I want to reflect upon how design is articulated and how design is taught; about the role of design in engineering education and in the practice of engineering; and about the role that could be played locally and, perhaps, nationally by a center devoted to design education. Because I teach here at Harvey Mudd College (HMC), …

Issues In The Design And Implementation Of Expert Systems, Clive L. Dym
All HMC Faculty Publications and Research
This article discusses the issues that arise in the design and implementation of expert systems. These issues include: task selection; the stages of development of expert system projects; knowledge acquisition; languages and tools; development and run-time environments; and organizational and institutional issues. The article closes with some speculation about the future development of expert systems.
