| Summary: | 碩士 === 大同大學 === 工業設計學系(所) === 92 === This study starts from analyzing the basic concept of “transparent” to discuss the psychological effect about the finishing on transparent plastic used on lipsticks. The objective of this study is to find the correspondence between the characteristics of transparent materials used for lipsticks and the consumers’ image in order to obtain the related design element which can be used as a main principle for product design.
The study is conducted in three parts. 1. The first step is to use open questionnaires to have a general idea about the associated phrases used to describe transparent image. The cluster analysis method is used to study the concept of transparent and the elements which can be applied for product design. 2. The second step is to design lipstick samples to perform a pre-test about transparent image. The MANOVA (Multivariate Analysis of Variance) is performed to discuss how the parameters, such as different lipstick shapes or the method for finishing, etc., affect the images. 3. The final step is to select parameters which will have significant effects on the design of transparent lipstick. The researcher applied these parameters to design lipstick samples and performed the SD (Semantic Differential) image test. The results are discussed by principal component analysis and cluster analysis to define the image structure of transparent lipstick and the correspondence between transparent material properties and images. MANOVA is used to exam the correlation between material properties and transparent images. Finally, multiple regression analysis is used to define the cause-effect relation between individual preference and images and converts these results into design elements for verification. The key results from this study are summarized in below.
1. For most consumers, the concept of Transparency is composed by 2 main parts: light and concealment. The sub-concepts include open, elegant, crystal, vivid, concealed and mysterious. Light is an outward concept but concealment is an inward concept. Therefore, applying these 2 concepts to product design requires difference methods and will have completely different effects. Light is applied for fully transparent design. In this case, the main idea is to create an image of wide and free which can be seen thoroughly at the first sight. On the contrary, concealment is the application for semi-transparent materials in which a vague and ambiguous impression is created and provides a space for imagination.
2. The transparent image of lipstick is composed by 2 factors: “delightful vs. gloomy” and “rational vs. perceptual.” Fully transparent represents delightful and rational and the semi-transparent represents gloomy and perceptual. The effect of light reflection will multiply the impression of delightful and perceptual.
3. “Transparency without etching” has the highest level of transparent image and is the consumers’ favorite. Rough etching has an impression of old and conservative and this is the reason why rough etching is the least popular one. Finishing by etching can create an image of fantastic, sentimental, tender and mysterious.
4. The synthesis evaluation of “preferable” is affected by the image of fashionable. The lipsticks with the finishing of transparency without etching and the uneven thickness are the one with highest impression of fashionable. In other words, lipsticks designed with these 2 properties will represent fashion and consumers will love it.
