O uso das emoções para o desenvolvimento de produtos sustentáveis

Podlasek, Celso Luiz 11 April 2013 (has links)
A presente tese é um trabalho de pesquisa em design e sustentabilidade, que visa expor uma estratégia para utilização das emoções no desenvolvimento de produtos sustentáveis. Inicialmente houve a descrição de alguns dos principais métodos e teorias que cercam o design e a sustentabilidade, e como lacunas entre eles permitem que os vários tipos da obsolescência contaminem o processo de desenvolvimento, comercio e utilização dos produtos, causando inúmeros danos aos consumidores, sociedade e meio ambiente. O capítulo 4 monta um texto que envolve o consumo como um elemento de construção e significação cultural, estando presente na sociedade como um sistema complexo de signos que intermedia e complementa relações sociais. Este capítulo é a ponte para aproximar as emoções com o design e a sustentabilidade, cujas teorizações seguem nos capítulos 5 e 6. As emoções envolvem uma construção teórica que parte de conceituações amplas, entre a filosofia e a sociologia, para em seguida mergulhar especificamente sobre suas manifestações fisiológicas nos indivíduos. As considerações do neurocientista António Damásio, que descreve as emoções como principal elemento na tomada de decisões de cada indivíduo, são especialmente importantes, pois nelas repousam muitas das características semânticas que balizam nossas tomadas de decisões, inclusive aquelas que envolvem os atos de consumo. Todas as teorizações neste trabalho são um plano epistemológico que abre caminhos para uma nova exploração em design. Esta exploração é a exposição empírica de uma estratégia de utilização das emoções para o desenvolvimento de produtos sustentáveis, tendo como meta principal se contrapor à obsolescência. Para isto, foram utilizados objetos que carregam o poder de despertar grandes apelos emocionais em seus proprietários. Realizou-se uma técnica mista que iniciou com entrevistas semiabertas de seleção. Em seguida nove voluntários selecionados, em entrevistas abertas, descreveram relatos de suas vidas com o intermédio de seus objetos emocionais. A partir dos relatos destas entrevistas, fez-se correlações identificando as semelhanças que se agrupavam por influência cultural. A última etapa de experimentos passou para testes quantitativos de eletroencefalograma, mensurando e comparando as manifestações fisiológicas que os objetos emocionais causam em seus proprietários. Os resultados destes testes possibilitaram a indicação de aprofundamentos para as etapas qualitativas da pesquisa, bem como apontamentos diretos para uma estratégia que utilize as emoções para o desenvolvimento de produtos sustentáveis e menos suscetíveis ao descarte prematuro. / The present thesis is a research work in design and sustainability, which aims to expose a strategy for the use of emotions in the development of sustainable products. Initially there was a description of some of the main methods and theories surrounding the design and sustainability, and how they allow gaps between the various types of obsolescence contaminate the process of development, trade and use of the products, causing severe damage to consumers, and society environment. Chapter 4 rides a text that involves the consumption as an element of construction and cultural significance, being present in society as a complex system of signs that complements intermediate and social relations. This chapter is a bridge to bring the emotions with the design and sustainability, whose theories follow in chapters 5 and 6. Emotions involve a theoretical construct that part of broader conceptualizations, between philosophy and sociology, to then delve specifically about their physiological manifestations in individuals. The considerations of neuroscientist Antonio Damásio, who describes the emotions as the main element in the decision-making of each individual, are especially important because many of them lie semantic features that guide our decision making, including those involving acts of consumption. All theories in this work is an epistemological level that opens new avenues for design exploration. This exploration is exposure empirical strategy of using emotions to the development of sustainable products, having as main goal to counteract obsolescence. For this, we used objects that carry the power to awaken great emotional appeals for their owners. We conducted a mixed technique that began with open-ended interviews selection. Then nine volunteers selected in open interviews, described reports of their lives with their objects through emotional. From the reports of these interviews, it became correlations identifying the similarities were grouped by cultural influence. The last step of experiments passed tests for quantitative electroencephalography, measuring and comparing the physiological manifestations that cause emotional objects in their owners. The results of these tests allowed the indication for deepening the steps of qualitative research as well as direct pointers to a strategy that uses emotions to the development of sustainable products and less susceptible to premature disposal.

Process-based modeling for cradle-to-gate energy and carbon footprint reduction in product design

Alsaffar, Ahmed J. 21 March 2012 (has links)
Interest in accounting for environmental impacts of products, processes, and systems during the design phase is increasing. Numerous studies have undertaken investigations for reducing environmental impacts across the product life cycle. Efforts have also been launched to quantify such impacts more accurately. Life cycle energy consumption and carbon footprint are among the most frequently adopted and investigated environmental performance metrics. As efforts continue to incorporate environmental sustainability into product design, struggles persist in concurrent consideration of environmental impacts resulting from the manufacturing processes and supply chain network design. Thus, the objective of this research is to present a framework for reducing product cradle-to-gate energy consumption and carbon footprint through simultaneous consideration of manufacturing processes and supply chain activities. The framework developed in this thesis relies on unit process modeling, and is demonstrated for production of a bicycle pedal. It is shown that simultaneous consideration of manufacturing and supply chain processes can impact decision-making and improve product environmental sustainability at the design stage. The work presented contributes to the state of the science in sustainable design and manufacturing research. In addition, a point of departure is established for the research community to move current efforts forward for concurrent consideration of multiple stages of the product life cycle in pursuit of environmental, economic, and social sustainability. / Graduation date: 2012
