New food product development is so often confronted with failure in the market. One of the significant reasons is, nowadays, the customer preference is no longer simply only determined by a few factors rather a combination of various needs. This article presents an affective engineering methodology “Kansei Engineering” which can tailor the product by the customer need. This methodology is able to assist the food product developer to connect the consumer affection with the product properties in order to develop the food product with the most affective influence deep in customer’s mind associated with product. Using this systematic affective methodology “Kansei engineering” approach would help the company to develop the food with consumer amenity.

A seleção de formas e materiais é uma das etapas iniciais no desenvolvimento de embalagens e gera muitos impactos desde o processo de fabricação, o sucesso no mercado até o descarte na natureza. Existem métodos para incorporar as necessidades dos clientes e traduzí-las em requisitos técnicos de produto e, dentre estes, destaca-se a Engenharia Kansei, que tem como principais características a alta participação do usuário/consumidor no projeto do produto através de técnicas e ferramentas de cunho matemático e computacional e que busca traduzir as percepções do consumidor em requisitos de produto. Neste sentido, esta dissertação apresenta uma proposta de um Sistema de Engenharia Kansei que integre as impressões do público alvo com critérios de sustentabilidade em embalagens de doce de leite. O objetivo foi o desenvolvimento do sistema para selecionar o desenho de embalagem que fosse preferencial pela análise do público alvo, e mais sustentável do ponto de vista dos critérios adotados. As impressões do público alvo foram obtidas através da aplicação de questionários e posteriormente relacionadas pelas técnicas de teoria de quantificação tipo I e números fuzzy triangulares integradas com um sistema inteligente baseado em algoritmo genético. Os critérios de sustentabilidade adotados foram índice de emissão de CO2, índice de reciclagem no Brasil, tempo de decomposição na natureza e vantagem econômica na utilização de insumos reciclados. Os materiais analisados foram vidro, aço e polipropileno (PP), que são os principais encontrados no mercado brasileiros para embalagens de doce de leite que compõe os principais itens de forma do produto (corpo e tampa). Os resultados mostraram a viabilidade da utilização da Engenharia Kansei no processo de desenvolvimento de produtos, em especial na etapa de seleção do produto além da proposta de incorporação de critérios sustentáveis na avaliação das embalagens, proporcionando uma melhoria na tomada de decisão de alternativas no projeto de produtos. / The product development that considers sustainability and potential costumers needs aspects on it the process has become more important to the competitiveness of organizations and to the environment either. The design and materials selection is one of the initial steps in the development of packages and its results generate impacts that ranges from the manufacturing processes, the marketplace success and the disposal in nature. There are methods that to incorporate the costumers needs and translate it in product technical requirements and, among these, Kansei Engineering stands out, it has as the main features the high user/consumer participation in the product design through matematical and computational techniques and tools that attempt to translate consumer´s perceptions in product requirements. In that sense, this dissertation presented a proposal of Kansei Engineering System that integrates the consumer´s perceptions with susteinability criteria about sweet milk packages design. The aim was the system development to select the packaging draw preferencial for the target public and more sustainable about the adopted criteria. The consumer´s perceptions were colected using questionares and after worked applying quantification theory type I and fuzzy triangular numbers integrated with a expert system based in genetic algorithm. The sustainability criteria adopted was CO2 emissions rate, recycling rate in Brazil, decomposition time in nature and the materials reuse financial return used in each package model. The materials used in the research are glass, steel and polypropylene plastic (PP), which are found on packages in the Brazilian market and composes the main components of the package; body and lid. The results show the feasibility of using Kansei Engineering in the product development process, especially in the selection product shapes step moreover the proposal of incorporation sustainability criteria to evaluate packages, provinding improvements in decision-making insertion of more sustainable packages in the Market.

Because of the competitive market and high product failure, product development and quality is moving towards a merging of functionality and usability with psychological needs. The interaction with the products creates a need, which can be a decisive aspect for the user when choosing a product. The Kansei approach, also known as Kansei Engineering, aims at converting the psychological needs that influence the subjective perception of the user, into actual design specification, with eight types developed so far. Furthermore, the method implies that, the competitiveness of the product can be enhanced by attaching users’ feelings and aesthetic impressions in term of product attributes, to the product features.This thesis describes how the methodology can be used by implementing Kansei Engineering Type I as a tool to evaluate and map the subjective perceptions of dining tables. The research shows that it was possible to map correlations between the users’ subjective perception and design features. E.g. a dining table that is perceived as solid, has the feature rail/frame and is heavy (>35kg). This can be used as input in user-centred product development. Even if no correlation was possible in some cases, valuable information was gathered that can be used for further analysis. As a continuation of the research, will be to focus on which surface textures is better perceived as natural feeling of wood.

Design thinking (DT) is a popular method and methodology for leveraging innovation. However, using DT in practical organisational settings is challenging because there is little acknowledgment of such research in academia. The few existing researches about the utilization of DT has been misinterpreted by organisations due to the phenomenon on wicked problems, leading to misuse of the method. This research investigates and enhances interdisciplinary approaches that can enhance the utilization of DT in product development for driving innovation. This qualitative case study was conducted by two full-time engineer students over a span of twenty weeks, starting in mid-January, as a thesis project for their industrial product realization studies at Jönköping University. The case study was carried out at a manufacturing company, Thule, in Sweden, specializing in outdoor recreational products. Using the IDEO method of DT, the study implements a systematic approach to develop a new, innovative solution. The project began with an extensive analysis of the market competition, users, and the company Thule, using innovative techniques such as brainstorming and various stages of sketching to address identified user challenges. Utilizing DT methods for innovation was successful as the insights were transformed into a tangible concept using computer-aided design and prototyping tools. As a result of implementing DT, a conceptualised approach was developed that ultimately lead to the innovative idea of creating a modular camping box mounted to the car's tow bar.

There is an increasing emphasis on developing systematical research approaches for design of products that appeal to people’s emotions and values. This thesis proposes methodological developments for investigating people’s subjective emotional needs and values towards quality and explores interactions of related physical design attributes for product design. The overall aim of the licentiate thesis is to gain an understanding on Affective engineering of products through exploring the concept of quality feeling and to develop methodological approaches for this. Quality feeling can be described as a holistic concept considering individuals’ perceptions, expectations, experiences, physical and psychological expressions for a product or service. Affective Engineering methodology aims at translating human psychological processes, such as feelings and emotions, into appropriate product design attributes, such as size, shape, and surface characteristics. The thesis presents three methodological approaches when evaluating products for affective engineering and one approach for an interactive product design support system development. The first study presented deals with feelings of quality for reach truck operator’s cabin components. Components that would convey to give a higher total quality feeling were identified and improvement opportunities were prioritized. The second study presented is based on developing an interactive affective design and decision support system software for design of the steering wheel from drivers’ individual and shared preferences. In the third study affective values arising from judgments for important feelings of quality is the study basis. The author presents research on identifying interactions of design attributes for affective values in waiting areas of primary health care services. Further, a new approach for applying Affective Engineering in design of complex contexts is proposed.The proposed approach aims to handle contexts where feelings and design attributes have complex interactions for products and services that give almost an infinite number of design alternatives that are difficult to handle in traditional Kansei Engineering studies. With this thesis also an interactive product design and decision support system software is developed for steering wheel design and proposed for educational and industrial use. The proposed system works based on linking product design attributes to human feelings by applying Genetic algorithms and provides potential basis for future product development and improvements. This thesis has also contributed with affective design recommendations applicable for vehicle cabins and waiting areas in primary health care. Moreover, a number of existing methods in Affective Engineering have been tested and methodological experience is drawn, including advantages, disadvantages and limitations of using these methods.

Tendencies in product development of today make it likely that many future products will be functional equivalent and therefore hard to distinguish between for the customer. Customers will decide by highly subjective criteria which product to purchase. One task for product development in this context is to be able to capture the customer’s considerations and feelings of products and translate these emotional aspects into concrete product design. Today a number of different methods, such as Quality Function Deployment (QFD), Semantical Environment Description (SMB), Conjoint Analysis and Kansei Engineering exist and are used in practical applications. The purpose of this thesis is to understand and apply Kansei Engineering methodology and explore ways to integrate the methodology into an industrial product development process. This was done by conducting a study on forklift trucks in different European countries and business areas and by exploring ways of integrating Kansei Engineering in product development processes. The number of Kansei words collected was reduced based on the result of a pilot study using a combination of different tools. A computerized data collection method was used in combination with a modified VAS-scale in order to reduce the time for filling out the evaluation forms The results of the study in the visited Northern and Middle European companies make it evident that Kansei Engineering has to be adapted in several aspects to the circumstances in each situation. The data showed that there are differences in attitude towards reach trucks in the different European countries. These results were used in order to adapt the product requirements for each specific country. Starting at Cooper’s stage gate model Kansei Engineering was applied on a macro level, a micro level and for verifying purpose. Using QFD, Kansei Engineering helps to identify customer needs their importance and the technical responses as well as to conduct benchmarking and to connect the customer needs mathematically to the technical responses. This study of Kansei Engineering revealed that there was no general model on the methodology available in English literature. Outgoing from a previous flowchart, a conceptual framework of Kansei Engineering was developed integrating the existing Kansei Engineering Types and future tools. / <p>ISRN/Report code: LiU-Tek-Lic 2002:19</p>

O envolvimento do consumidor é fundamental nas fases iniciais de projetos de produtos inovadores, para a coleta de informações sobre interesses e preferências orientadores do processo de geração de ideias e conceitos de novos produtos. Uma das formas de viabilizar este envolvimento é utilizando ferramentas do tipo Sistema de Engenharia Kansei. Esse tipo de ferramenta permite a tradução de inputs de grande volume de consumidores em configurações de produtos otimizados para auxiliar a equipe de projeto, no Processo de Desenvolvimento de Produtos. Há duas principais limitações nos Sistemas de Engenharia Kansei propostos na literatura. A primeira é a operacionalização do envolvimento do consumidor na etapa de definição do campo das propriedades, i.e., captação dos dados de entrada dos consumidores. A segunda é a continuidade do envolvimento, com a intenção de fornecer informações atualizadas à equipe de projetos de produtos. Este trabalho propõe e testa procedimento automático para apoiar a definição do campo das propriedades utilizando inputs indiretos de consumidores obtidos em lojas virtuais, empregando e adaptando métodos utilizados em aplicações de Sistemas de Engenharia Kansei e Sistemas de Recomendação Híbridos. O procedimento automático fornece como resultado principal uma lista de produtos e propriedades, obtidos da realidade, representativos do domínio Kansei para utilização nas etapas posteriores de um Sistema de Engenharia Kansei. O teste do procedimento automático demonstrou que a dissimilaridade presente no conjunto inicial de produtos determina o número máximo de produtos representativos do domínio; e, que o grupo de produtos e propriedades representativos do domínio, obtido da aplicação do procedimento automático, pode apresentar disparidade com relação a um grupo referencial obtido utilizando método de planejamento de experimentos, embora atenda aos critérios informados na literatura seminal de Engenharia Kansei. / The customer involvement is critical in the early stages of innovative projects, to collect information about guiding interests and preferences of the process of generating ideas and concepts of new products. One way to facilitate this involvement is using the type system of Kansei Engineering tools. This type of tool allows the translation of large volume of inputs of consumers in products optimized settings to assist the project team, the Product Development Process. There are two main limitations in Kansei Engineering Systems proposed in the literature. The first is the operationalization of consumer involvement in the step of defining the field of properties, i.e., capture the input data consumer. The second is the continued involvement with the intention to provide updated information to the team of product designs. This thesis proposes and tests automatic procedure to support the definition of the properties field using indirect inputs of consumers obtained in virtual stores, using and adapting methods used in applications of Kansei Engineering Systems and Hybrid Recommender Systems. The automatic procedure provides as main result a list of products and properties obtained from reality, representative of Kansei domain for use in the later stages of a Kansei Engineering System. The automatic test procedure showed that the dissimilarity present in the initial product set determines the maximum number of products representative of the field; and that the product group and representative properties of the domain obtained from the application of the automatic procedure can present disparity with respect to a reference group obtained using planning method of experiments, although meets the criteria given in the seminal literature Kansei Engineering.

The User Experience (UX) has become a major concern for the design of consumer products. Today exist various tools for the evaluation of static properties of final products on their User Experience value. However, very few tools and methods are available that allow anticipating the future User Experience during the first stages of product conception. This thesis explores the wide range of design dimensions that potentially form the experience of the user. Dynamic product properties emerge as an important factor for User Experience. In the studies a software based on inspiration words and links, as well as the technique body storming are tested as a new means of User Experience generation. The produced early concepts and interaction gestures are then evaluated through a combination of questionnaires, behavioural and physiological measurements. The study results show firstly that a wide range of design dimension needs to be regarded to design for User Experience, secondly that it is possible to apply UX evaluations on early concepts and thirdly that UX evaluations can also be done on dynamic properties like interaction gestures. This thesis furthermore contributes design research and practice with a new model on the mechanism of User Experience and a list of design dimensions for early product conception.
