User Study Of Information Extracted From Engineering Representations, Rachel Hannah
User Study Of Information Extracted From Engineering Representations, Rachel Hannah
All Theses
It is important for designers to understand the usefulness of different engineering representations in order to save time and money throughout a project. Designers often rely on past experience to decide which model to construct; yet students without this experience have no help. Interestingly there are noticeable gaps in the research literature with respect to how and when to select representations and modeling approaches for engineering designs. This thesis examines the differences between three types of engineering representations, specifically sketches, drawing packages, and physical prototypes. The amount of information designers can extract from these representations and also the correctness and …
Taxonomy Of Physical Prototypes: Structure And Validation, Ashwin Michaelraj
Taxonomy Of Physical Prototypes: Structure And Validation, Ashwin Michaelraj
All Theses
This thesis introduces a taxonomy of physical prototypes, and validates the proposed taxonomy by five different approaches. The proposed taxonomy is validated by, (i) checking the orthogonality of individual elements of the taxonomy, (ii) benchmarking the taxonomy with existing classifications of prototypes, (iii) demonstrating its utility by applying it to classify different prototypes, (iv) building a prototype database containing 35 different prototypes, and (v) consistency evaluation of the prototype database using a description logic based software called ProtŽgŽ.
The results indicate that the proposed taxonomy is capable of distinguishing prototypes with greater accuracy when compared to existing classifications. The orthogonality …
Investigating The Role Of Prototyping In Mechanical Design Using Case Study Validation, David Stowe
Investigating The Role Of Prototyping In Mechanical Design Using Case Study Validation, David Stowe
All Theses
The purpose of this research is to explore the application of prototyping in the design process through a case study analysis using structured interviews, an ethnographic study, and documents analysis, to determine what factors and practices result in successful prototyping. In doing so, research questions are established, a prototyping process is developed to assist the investigation, and classification systems are created to organize data collected in the study. As part of the case study, an interview is formulated to answer the proposed research questions and a literature survey of prototyping in design is used to create a larger analytical foundation. …
