Produto Aquaoli: projeto de design industrial em aquariofilia

Esta dissertação de mestrado, apresenta a elaboração de um projeto de design industrial em aquariofilia - Aquaoli. Pretende-se criar uma nova tipologia de aquários inovadora e distinta, projetando o produto com o intuito deste cumprir com todos os parâmetros exigidos pelo mercado e produção do mesmo. Definiu-se a criança entre os 7 e os 11 anos como público-alvo deste projeto. Assim, pretende-se um resultando promissor para a empresa AQUATLANTIS apostar e lucrar com o seu desenvolvimento. Para que este projeto obtivesse bons resultados, foi realizada uma pesquisa aprofundada, desde a aquariofilia (a sua história, biologia e mercado), do aquariófilo atual (psicologia do consumidor e as suas responsabilidades), até ao estado da arte (da AQUATLANTIS e dos produtos existentes no mercado). Este projeto foi desenvolvido em várias vertentes de design, procurando ser o mais completo possível. Isso foi viável com o desenvolvimento do produto e de todos os seus componentes em três dimensões, o desenvolvimento de maquetes e de protótipos do produto, o desenvolvimento do packaging e campanha promocional, a definição de preço custo e métodos de produção dos objetos, entre outros parâmetros. Obteve-se um projeto de design industrial bastante completo e com potencial para ser implementado no mercado, cativando a atenção do público-alvo e obtendo vendas elevadas. O aquário apresenta-se distinto dos existentes, principalmente no facto de ser modular, muito interativo, pedagógico e incorporar uma estrutura invulgar e particularmente cativante para as crianças. Este produto subdivide-se em dois conjuntos vendidos separadamente (Aquarium Pack e Kit-1 Pack), apresentando assim uma estratégia de marketing que pretende que a criança que o adquira pela primeira vez, venha a desejar adquirir mais produtos desta gama, procurando aumentar a sua estante e/ou o número de aquários e animais que incorpora na mesma.

A valorização das heranças culturais através do design

A presente investigação versa a ligação do design às heranças culturais. Num período em que as fronteiras se vão de certa forma dissolvendo, há, por um lado, um maior risco de perdas de identidades e tradições, mas também, por outro lado um maior interesse pela procura dessas mesmas identidades. Tenta-se, com esta investigação, perceber se a ligação do design às heranças culturais e vice-versa poderá trazer mais valias para ambos. Isto é, o design como mediador entre as heranças culturais e as pessoas, fomentando o interesse do público pelas tradições e legado cultural, valorizando o conhecimento, conservação e preservação dos mesmos. Procura-se, também, perceber se o design poderá aproveitar esta aproximação como uma força potenciadora para se impor e prosperar, tanto no mercado nacional como no internacional. Se o design português precisa de algo único, como a cultura portuguesa, também as heranças culturais precisam de ser vistas por um novo prisma, e aqui é proposto entrar o design. Baseada na critica literária e casos de estudo, tanto nacionais como internacionais, respondeu-se às perguntas colocadas no inicio da dissertação. Foi também criado o projeto Da Panela de modo a provar as respostas afirmativas às mesmas questões. O projeto Da Panela propõe uma reflexão sobre o panorama gastronómico minhoto, evocando a sua memória e conhecimento, numa colaboração entre design e gastronomia para a criação de novos produtos que pretendeu revitalizar uma região e uma tradição, dando-lhe novas interpretações e formas, que promovam o conhecimento e valorizem os seus recursos. Um projeto que transpôs esta herança tão tradicional para os dias de hoje, possibilitando novas experiências e novos usos, aplicados ao contexto e necessidades atuais.

Mechatronic system for ABO human blood typing

In medical emergency situations, when a patient needs a blood transfusion, the universal blood type O− is administered. This procedure may lead to the depletion of stock reserves of O− blood. Nowadays, there is no commercial equipment capable of determining the patient's blood type in situ, in a fast and reliable process. Human blood typing is usually performed through the manual test, which involves a macroscopic observation and interpretation of the results by an analyst. This test, despite of having a fast response time, may lead to human errors, which sometimes can be fatal to the patient. This paper presents the development of an automatic mechatronic prototype for determining human blood typing (ABO and Rh systems) through image processing techniques. The prototype design takes into account the characteristics of reliability of analysis, portability, and response time allowing the system to be used in emergency situations. The developed prototype performs blood and reagents mixture acquires the resultant image and processes the data (based on image processing techniques) to determine the sample blood type. It was tested in a laboratory, using cataloged samples of blood types, provided by the Portuguese Institute of Blood and Transplantation. Hereafter, it is expected to test and validate the prototype in clinical environments.

Conceptual design of a conveyer system for supporting basic quality of life of bedridden elderly people

With the increasing number of aged people, especially in developed countries, Ambient Assisted Living solutions have become an important subject to be explored and developed. Currently, as specialized Institutions in geriatric care cannot cope with the increasing requests for support of quality of life, patients have to remain at their homes having as caregiver the other member of the couple or a member of close family. A solution for supporting the caregiver, during assisting the bedridden person with some basic tasks as eating, taking a bath and/or hygiene care is of utmost importance. This paper presents an approach for supporting the caregiver in moving and repositioning the bedridden elderly people (BEP) with the assistance of a mechanical system conveyer. The conceptual design of the mechanical system must be devoted to assist the caregiver in the handling and repositioning of the BEP. The proposed mechatronic system must, ideally, minimize the system's handling complexity, reduce the number of caregivers and the amount of spended and needed effort.

Conceptual design of a mechatronic system for supporting basic quality of life of bedridden elderly people

Ambient Assisted Living is an important subject to be explored and developed, especially in developed countries, due to the increasing number of aged people. In this context the development of mechatronic support systems for bedridden elderly people (BEP) living in their homes is essential in order to support independence, autonomy and improve their quality of life. Some basic tasks as eating, taking a bath and/or hygiene cares become difficult to execute, regarding that often the main caregiver is the other element of the aged couple (husband or wife). This paper presents the conceptual design of a mechanical system especially devoted to assist the caregiver in the handling and repositioning of the BEP. Issues as reducing the number of caregivers, to only one, and reducing the system's handling complexity (because most of the time it will be used by an aged person) are considered. The expertise obtained from the visits to rehabilitation centers and hospitals, and from working meetings, are considered in the development of the proposed mechatronic system.

Teaching drawing: an interdisciplinary pedagogical experience in a graphic design course

Various authors have written about the importance of drawing in design methodology. Their general conclusion points drawing as an essential tool for design research, as it allows investigation of several alternative solutions in design process (Cross, 2007). The recent profound changes in design nature (Norman, 2011), justify a discussion on the purpose of drawing in design courses. As a consequence of this new reality, the educational institutions face the challenge of the definition of their curricular structures and teaching methodologies. Among others, concepts such as collaboration and multidisciplinary design approaches have been discussed as strategies for design education (Heller and Talarico, 2011, pp. 82-85). In this context, and using our teaching activity experience in Drawing and Design areas, the authors discuss:  how can drawing methods be included in the current design teaching?  can drawing be considered as an interdisciplinary approach?  what contributions can these methodologies provide to the educational/learning process? Based on these concerns, we developed an interdisciplinary project in the Graphic Design Course with two curricular units: Drawing 1 and Aesthetic and Design Theory 1. In this article the authors present the aims and process developed, and discuss the outcomes of this pedagogical experience.

Exploring the interdisciplinary process in design education

The work presented herein follows an ongoing research that aims to analyze methodological practices to be applied in Design Education. A reflection about methodological strategies in Design Education and the function of drawing in Design represents the beginning of this study. Then, we developed an interdisciplinary pedagogical experience with the Graphic Design 1st grade students from our institution (IPCA). In the current academic year, 2013/2014, we continue to evolve this project, introducing changes in the initial proposal. Major alterations focused on the aspects that could be strengthened in terms of interdisciplinarity. In this article, the authors describe those changes and discuss the outcomes of the novel proposal. As we have already reported, this investigation follows a reflection about working methods to be adopted in Design Education. This is in accordance with other previously published works that purpose the enlargement of Design into new knowledge fields such as Experience or Service Design, changing not only the role of the graphic designer, but also the skills required to be a professional designer (Alain Findelli, 2001), (Brian Lawson, 2006), (Ciampa-Brewer, 2010). Furthermore, concepts such as cooperation or multidisciplinary design, amongst others, have been frequently debated as design teaching strategies (Heller and Talarico, 2011, pp. 82-85). These educational approaches also have an impact on our research. The analysis of all these authors’ contributions together with a reflection on our teaching practice allowed us to propose an improved interdisciplinary intervention.

An Electromagnetic Tracker System for the design of a dental superstructure

Nowadays, different techniques are available for manufacturing full-arch implant-supported prosthesis, many of them based on an impression procedure. Nevertheless, the long-term success of the prosthesis is highly influenced by the accuracy during such process, being affected by factors such as the impression material, implant position, angulation and depth. This paper investigates the feasibility of a 3D electromagnetic motion tracking system as an acquisition method for modeling such prosthesis. To this extent, we propose an implant acquisition method at the patient mouth, using a specific prototyped tool coupled with a tracker sensor, and a set of calibration procedures (for distortion correction and tool calibration), that ultimately obtains combined measurements of the implant’s position and angulation, and eliminating the use of any impression material. However, in the particular case of the evaluated tracking system, the order of magnitude of the obtained errors invalidates its use for this specific application.

Electromagnetic tracker feasibility in the design of a dental superstructure for edentulous patients

The success of the osseointegration concept and the Brånemark protocol is highly associated to the accuracy in the production of an implant-supported prosthesis. One of most critical steps for long-term success of these prosthesis is the accuracy obtained during the impression procedure, which is affected by factors such as the impression material, implant position, angulation and depth. This paper investigates the feasibility of 3D electromagnetic motion tracking systems as an acquisition method for modeling full-arch implant-supported prosthesis. To this extent, we propose an implant acquisition method at the patient mouth and a calibration procedure, based on a 3D electromagnetic tracker that obtains combined measurements of implant’s position and angulation, eliminating the use of any impression material. Three calibration algorithms (namely linear interpolation, higher-order polynomial and Hardy multiquadric) were tested to compensate for the electromagnetic tracker distortions introduced by the presence of nearby metals. Moreover, implants from different suppliers were also tested to study its impact on tracking accuracy. The calibration methodology and the algorithms employed proved to implement a suitable strategy for the evaluation of novel dental impression techniques. However, in the particular case of the evaluated electromagnetic tracking system, the order of magnitude of the obtained errors invalidates its use for the full-arch modeling of implant-supported prosthesis.

On universal central extensions of Hom-Leibniz algebras

In the category of Hom-Leibniz algebras we introduce the notion of Hom-corepresentation as adequate coefficients to construct the chain complex from which we compute the Leibniz homology of Hom-Leibniz algebras. We study universal central extensions of Hom-Leibniz algebras and generalize some classical results, nevertheless it is necessary to introduce new notions of α-central extension, universal α-central extension and α-perfect Hom-Leibniz algebra due to the fact that the composition of two central extensions of Hom-Leibniz algebras is not central. We also provide the recognition criteria for these kind of universal central extensions. We prove that an α-perfect Hom-Lie algebra admits a universal α-central extension in the categories of Hom-Lie and Hom-Leibniz algebras and we obtain the relationships between both of them. In case α = Id we recover the corresponding results on universal central extensions of Leibniz algebras.
