Capstone Design

The increasing complexity of engineering and technology requires that students master an increasing amount of abstract knowledge to remain competitive in today’s job market. However, today’s students find it difficult to create mental images of abstract concepts, due to lack of real world experience. This problem is more evident in advanced design classes teaching product design concepts and methodologies. In this paper, we introduce a system engineering software package that is used in our capstone design class, with which students are able to create their own framework of product development activities, control information flows, and manage tools and engineering models in each activity. This allows them to plan out and manage their projects using the design methodologies that they learned in class. We assessed student learning in the capstone design class for the last 7 semesters. Independent Samples t-Test and factorial ANOVA are used to analyze the student performance before and after using the software package. We have observed that in the design classes, the system engineering software enables students to practice design methodologies by visualizing and managing product development processes. This helps students not only understand the abstract design methodologies, but also apply the methodologies to their projects and accomplish them more efficiently.

An accurate understanding of users' needs is essential for the development of innovative products. This article presents an exploratory method of user centered research in the context of the design process of technological products, conceived from the demands of a large information technology company. The method is oriented - but not restricted - to the initial stages of the product development process, and uses low-resolution prototypes and simulations of interactions, allowing users to imagine themselves in a future context through fictitious environments and scenarios in the ambit of ideation. The method is effective in identifying the requirements of the experience related to the product’s usage and allows rapid iteration on existing assumptions and greater exploration of design concepts that emerge throughout the investigation.

Course Outcomes

Purpose The purpose of this paper is to investigate undergraduate industrial design students’ perception of sustainable design concepts and how their conceptualization evolves as a function of their attendance to a specific sustainable design studio (SDS) course. Design/methodology/approach Two groups of students participated in the study. Students who did not attend to SDS were in the control group, whereas students who attended SDS were in the experimental group. In total, 22 concepts, which have been highlighted in literature and the SDS course, were selected as keywords. Participants were asked to provide relatedness scores of these keywords before and after they attended the course. The data were analyzed using multidimensional scaling and pathfinder (PF) networks. Findings Results indicate that the SDS caused a change in the conceptualization of sustainable design concepts parallel to the course outcomes and the literature. Some concepts were highlighted as conveyors that guide students to conceptualize sustainable development and design. Research limitations/implications This study is considered a case study focusing on declarative knowledge, and owing to the low number of participants, the results should be carefully interpreted. Practical implications The findings may support design educators to enhance their courses and promote deeper debates on teaching sustainable design. Originality/value Two specific dimensions were found from the analysis of multidimensional scaling, and several conveyor concepts were identified from PF networks. Allocating proposed dimensions and concepts into a course may have the potentials to enhance students’ perception of sustainability concepts.

Background Staging of rectal cancer with MRI has major impact on treatment choice and may be of importance in new cancer management strategies such as “wait-and-see” policy. Purpose To assess the reproducibility of a software package recently developed at our department to measure volumes, apparent diffusion coefficient, and the skewness of apparent diffusion coefficient in lymph nodes and tumors in rectal cancer patients before and after chemoradiation treatment. Material and Methods This study included 20 consecutive patients with biopsy-verified rectal cancer, in whom MRI staging had been performed both before and after chemoradiation treatment. The diffusion-weighted images were transferred to the software. The volume, apparent diffusion coefficient, and skewness were determined for 93 lymph nodes and 40 tumors. The volumes were compared with manual measurements of the volume of the same lymph nodes and tumors. Results The agreement in semi-automatic measurements of lymph nodes was very good (ICC = 0.99), and in tumors good (ICC = 0.88). The agreement in manual measurements of lymph nodes was very good (ICC = 0.95) when all lymph nodes were included, but low (ICC = 0.52) if three outliers were excluded. Bland–Altman plots showed clear agreement between manual and semi-automatic measurements in the lymph nodes, but not in measurements of tumors. The values of apparent diffusion coefficient and skewness in tumors differed before and after treatment but did not differ in lymph nodes as a group. Conclusion The software package showed a high degree of reproducibility in measurements on lymph nodes but requires further development to improve the reproducibility of tumor measurements.

Synergies and integration in design set a mechatronic system apart from a traditional, multi-disciplinary system. This paper proposes a method for the modularization and evaluation of different mechatronic design concepts in the early stages of product development processes. In order to consider the specific aspects of complex systems, a design metric is presented, which assists the design engineer in finding the best solution concept. For the description and evaluation of a complex mechatronic system, it is essential to decompose the total system into a hierarchical structure of mechatronic sub-modules. The number of levels in the decomposition, as well as the number of mechatronic modules involved, is indicative of the complexity of the design task.

This research proposes a patent-based design process by systematically integrating patent information, the rules of patent infringement judgment, strategies of designing around patents, and innovation design methodologies. The purpose of the process is to systematically generate new design concepts that are local variations of one of the concerned patents but does not infringe with existing patents. The basic idea is to consider patent infringement before engineering design concepts are actually generated. In this process, first the designer conducts standard patent analysis to identify the related patents to be designed around. Each patent is then symbolized by a “design matrix” converted from the technology/function matrix of the patent. A design-around algorithm is developed to generate a new design matrix that does not infringe with design matrices of existing patents. Then the new design matrix is transformed back into a real engineering design using the “contradiction matrix” in TRIZ. A computerized design-around tool based on the innovative patent-based design process is also developed.

This study focuses on the effect of part geometry and infill degrees on effective mechanical properties of extrusion additively manufactured stainless steel 316L parts produced with BASF’s Ultrafuse 316LX filament. Knowledge about correlations between infill degrees, mechanical properties and dimensional deviations are essential to enhance the part performance and further establish efficient methods for the product development for lightweight metal engineering applications. To investigate the effective Young’s modulus, yield strength and bending stress, standard testing methods for tensile testing and bending testing were used. For evaluating the dimensional accuracy, the tensile and bending specimens were measured before and after sintering to analyze anisotropic shrinkage effects and dimensional deviations linked to the infill structure. The results showed that dimensions larger than 10 mm have minor geometrical deviations and that the effective Young’s modulus varied in the range of 176%. These findings provide a more profound understanding of the process and its capabilities and enhance the product development process for metal extrusion-based additive manufacturing.

The coronavirus disease 2019 (COVID-19) pandemic has disrupted undergraduate medical education, including preclinical class-based courses, by requiring social distancing and essentially eliminating in-person teaching. The aim of this study was to compare student performance and satisfaction before and after implementation of remote instruction in a first-year introductory pathology course. Assessments (3 quizzes, 1 practical exam, and 1 final) were compared between courses given before (January 2020) and during (January 2021) the COVID-19 pandemic, in terms of mean scores, degree of difficulty, and item discrimination, both overall and across different question types. Students’ evaluations of the course (Likert scale-based) were also compared between the 2 years. Significantly higher mean scores were observed during remote instruction (compared to the prior, in-person year) on verbatim-repeated questions (94.9 ± 8.8 vs 89.4 ± 12.2; P = .002) and on questions incorporating a gross specimen image (88.4 ± 7.5 vs 84.4 ± 10.3; P = .007). The percentage of questions that were determined to be moderate/hard in degree of difficulty and good/very good in item discrimination remained similar between the 2 time periods. In the practical examination, students performed significantly better during remote instruction on questions without specimen images (96.5 ± 7.0 vs 91.2 ± 15.2; P = .004). Finally, course evaluation metrics improved, with students giving a higher mean rating value in each measured end point of course quality during the year of remote instruction. In conclusion, student performance and course satisfaction generally improved with remote instruction, suggesting that the changes implemented, and their consequences, should perhaps inform future curriculum improvements.
