Final Considerations on Prototypes in Design Research
No full textThe study Paride presented in this book was developed by a team of
researchers from the Department of Design of Politecnico di Milano. The aim was
to have a general understanding of how the role of prototypes in design research
is evolving. The investigation started with the literature review and analysis that
let us frame a general overview of the matter, later examined through interviews
with experts and a collection of case studies. We concluded that the general role of
prototypes in design research is to support the transition from abstract concepts to
defined design solutions. Prototypes can be used in specific phases of the research
process to reach particular aims throughout the design research process. Prototypes
arepurposefulandtransient objects made to concretize a conceptual idea. Playing
these roles and reaching these aims, prototypes can support the generation of new
knowledge—about and beyond the prototype itself—that can be translated into theoretical findings. These roles are evolving with the availability and integration of
advanced technologies and the development of design discipline that is broadening
and finalizing fields of research, methodology, and tools. The study had some limitations given to the time and extent of the investigation and other starting options
on the approach. Nevertheless, during the research, we also came across some interesting extra insights, aside from the central topic of our discourse, that are worth
mentioning and considering for further development
Prototypes for Industrial Design Research
No full textThis book provides a theoretical framework for design researchers interested in developing their research work about and with prototypes. It describes prototypes' multiple definitions and possible functions in the multifaceted landscape of today's design research. Indeed, while the manufacturing and digital evolutions enable and require new types of advanced prototypes, the design evolution as an academic discipline continuously widens its perspectives, fields, and research methods, among which are the prototypes' applications, features, and purposes. The framework originates from an interpretation of these interrelated phenomena and a collection of case studies. Additionally, it defines those criteria that characterize the relation between the research (context, discipline, and general scope) and the prototype (nature and specific aims) and, altogether, it presents an overview of prototypes' roles in design research
Making use of the Research Framework
No full textThe main objective of this research phase was to validate the findings of
the first part of the research and to develop a framework for the role of prototypes
in design research. We decided to validate our results by sharing them outside our
research group to gather feedback and deepen the discussion. Thus, we interviewed
nine researchers and practitioners in the design field. We shared our four theoretical
concepts with them and collected their opinions, which we later shared among the
research team members. Additionally, we asked the interviewees to share a case
study of one of their research projects where the prototype played a relevant role.
We asked for a short description of the research and prototype using the set of
categorization criteria developed in the analytical phase of the study. The collection
of these data proved to be valuable and complex. We anticipated the existence of
interesting relations among the criteria. Therefore, we made an interactive visual
tool that enabled us to discover and highlight such relationships. For instance, we
highlighted the relationship between the context and research aim or between the
prototype’s nature and the research phase. Eventually, as a discussion tool, it let
us observe our data and elicited further debate. Through this research phase, we
developed our general understanding of the phenomena

Evaluation of the magnetization direction effects on ferrite PM brushless fractional machines
No full textPermanent magnets are frequently adopted in small brushless machines for automotive applications. Normally anisotropic ferrites, but some research on bonded magnets is being carried on. Several types of magnetization can be proposed, involving different levels of complexity in the magnetization process. In the paper a comparison between parallel and radial magnetization is described, taking into account on one side the major complexity of the radial process and on the other the small power derating of the paralle

Low-cost electrochemical impedance spectroscopy system for corrosion monitoring of metallic antiquities and works of art
No full textElectrochemical impedance spectroscopy (EIS) is recognized to be a powerful and noninvasive technique to test the integrity of protective coatings on memorials, but commercial EIS systems are rather costly though versatile devices. This paper describes a low cost and portable EIS system that is based on a compact digital signal processor (DSP) board and embeds the potentiostatic function so that it can be used without requiring an external potentiostat. The software that runs on the DSP is designed to analyze the electrochemical impedance only in a reduced frequency range in order to produce a simple corrosion alert result. The device is equipped with a digital interface and can be connected to a personal computer to carry out a complete frequency analysis and perform a more complex data processing
Handheld-Impedance-Measurement System with seven-decade capability and potentiostatic function
No full textThis paper describes design and test of a new impedance-measurement system for nonlinear devices that exhibits a seven-decade range and works down to a frequency of 0.01 Hz. The system is specifically designed for electrochemical measurements, but the proposed architecture can be employed in many other fields where flexible signal generation and analysis are required. The system employs an unconventional signal generator based on two pulsewidth modulation (PWM) oscillators and an autocalibration system that allows uncertainties of less than 3% to be obtained over a range of 1 kΩ to 100 GΩ. A synchronous demodulation processing allows the noise superimposed to the low-amplitude input signals to be made negligibl
