Abstract [en]

In today’s markets, as the debate on customer oriented product development gets more intense, designing “Quality Feeling” in a product gain more and more importance. The basic objective of this study was to identify and analyze aspects of “Quality feeling” in a reach truck operator cabin. Kansei Engineering methodology was applied to research, how each component representing a reach truck operator cabin evoke quality feeling and how users experience quality feeling. Kansei Engineering (KE) is a consumer-oriented technology that aims to transfer customer’s perceptions, feelings and mental images into a tangible product. Quality feeling as a Kansei concept has investigated for two levels of perception in the study. The first level is comprised of Kansei words that are assumed to represent the feeling of quality for the reach truck`s operator cabin components. The second level is more general compared to the first one and concerns the views for direct Quality feeling representation of components. Forty-seven subjects evaluated eight operator cabin components of a reach truck on 7-degree SD scale, involving 20 Kansei words that represent the quality feeling. Reliability, Factor and Multivariate Regression Analyses were applied to the data gathered. The results showed that reach truck operator cabin components give rise to different perceived dimensions of quality feeling. The method used in the application moreover showed the most important operator cabin components in terms of their contribution to Total quality feeling for the reach truck. In conclusion the approach presented within this study can assist to determine user preferences and help product evelopers and designers to reflect quality feeling and other concepts.

Abstract [en]

Contemporary quality issues in product design are moving from materialistic to emotional user fulfillment; comprehensive research is needed to examine quality product feelings. This research is directed toward a deeper understanding of user and customer quality feelings for different product types, including services.

The quality feelings concept includes dimensions of product quality, especially functionality, ergonomics and aesthetics. The first objective of this thesis is to identify, prioritize and synthesize quality feelings into product attributes in product development applications. The second objective is to explore, test and propose methodological approaches for designing quality feelings into products.

Several methods from psychology, ergonomics, statistics and probabilistic methods and heuristics were applied to achieve the objectives. From a methodological viewpoint, Likert scales, free elicitation technique and Just About Right scales were applied for data collection. Multiple Regression, Factor Analysis, Correspondence Analysis, Genetic algorithms, Partial Least Squares (PLS) and Rough Sets (RS) were applied for data analyses. For ergonomic product evaluations, direct observations, 3D workload simulations, time and frequency analyses were conducted.

Five product applications are included in this thesis: operator driver cabin design of reach trucks, steering wheel design trigger switch design in right-angled nutrunners, bed-making systemsproducts and waiting room environments.

Heuristic methods were found effective when there is a high number of product attributes that interact to provide quality feelings. RS results are consistent with PLS attribute predictions. When the number of product attributes is large in comparison to the number of observations, PLS extracts informative results for quality feelings. The RS method is effective in identifying interactions among design attributes.

Quality feelings are associated with both tangible (tactile characteristics) and intangible (quick and easy to use) product characteristics. Words such as safety, functionality, ergonomics, comfort, reliability, supportiveness, usability, feedback, pleasantness, attractiveness, durability and distinctiveness describe quality feelings from tangible products and services. Based on product type, the quality dimensions represented by these words possess different interactions and dependencies. In work environments, products act as prostheses between workers for social interaction, which need to be considered as important quality feelings dimensions.
