Abstract

Nowadays, product design and development are geared at providing high-quality products and services at an affordable price to worldwide consumers. Successful product design is always the outcome of a perfect correlation between the designer's vision and the users' perception. This study was carried out in order to improve a design for a water bottle based on consumer emotions and perceptions applying the Kansei Engineering (KE) method to meet the expectations of the consumer. Kansei Engineering was used to gather and analyse consumer perceptions in to include it into design components (Kansei Word). Kansei engineering is a technique for converting human feelings and opinions expressed by user into design criteria. Significant Kansei words that have an effect on consumer satisfaction will become design priorities in the future. The purpose of this thesis is to comprehend and use the Kansei Engineering technique, as well as to study methods for incorporating the technology into the water bottle development process. However, KE is insufficient to analyse the data collected, but it still does not know what are required for product function. Furthermore, the Kano Model method was used to determine the functional of a water bottle and the correlation between the Kansei Word. The Kano Model's objective is to classify consumer expectations in the context of new product development and to evaluate the extent to which products produced in the direction of those expectations satisfy. Three objectives were presented in reference to the major purpose of this research: first, to study Kansei engineering and its implementation toward the design on product development. The second goal is to collect and analyse data from the questionnaire that is related to the product design aspect. The final goal of this research is to create a 3D model for a water bottle design. In this study, two surveys were conducted: a preliminary survey and a main survey. At the preliminary survey, five Kansei words were carried out of 15 Kansei words, which are (Safe, Practical, Comfortable, Durable, and Simple), as well as the top five design water bottle for 25 of design. The main survey was conducted to collect data on the chosen design and the Kano model (Functional) of the product. Using SPSS software, analyse the results to determine the relationship between the two variables Kansei word and Kano. According to the results, the most important features that should be included in future designs are 'Water level indicator, Handle Strap, Lid Attached, Bottle Car Holder, and Easy to Clean.' Following that, a morphological chart was used to create three concept designs base on the significant for a new water bottle,and the concept 2 was choose by PUGH matrix approach was used to determine which final design.
