| Summary: | 碩士 === 大同大學 === 工業設計學系(所) === 92 === The designer the possible role which holds the post in the expense society, one goes to the consumer which the store purchases the commodity, two is the user which uses the product, three is some item of product inventor. Therefore the designer becomes some sign disseminator, but simultaneously also becomes other signs receiver. The designer accumulates the knowledge not only comes from the education and the training, but also accumulates in the entire expense society to each sign, namely each kind of product, understanding and cognition.
The key point of this research lies in when the designer designs the product, his product knowledge, especially regard to the subject and experience-base knowledge which accumulates in the expense society, how to be applied, what to be applied for? And the knowledge varying degree whether can create the difference for application, as well as what influence on the design approaching strategy and the self- appraisal for design achievement? Different type knowledge regarding design conception development influence whether is in the degree of difference? For example, the subjective knowledge influences on the design approaching strategy more than the experience-base knowledge? It takes the electronic razor as the practical design case to observe the operation situation of the product knowledge in the design development.
The research take the experiment to execute, the sampling way is the quota sampling to invite the subjects for measuring the product knowledge and choose the appropriate people to join the experiment design assignment, finally by receiving the most satisfactory sketch in the design developing process to carry on recollection interview. To obtained questionnaire, design sketch and recollection interview list for analysis.
To take the integration, the descriptive statistics, the factor analysis, the cluster analysis, one-way ANOVA analysis, two-way ANOVA and the correlation analysis as the experiment data analysis tool. Experimental conclusion summary as follows:
1.About the knowledge application: there are six kinds of benefits to design for applying the experience-base , the frequency that they appear while the designer designed the products are : ” creating the expectation for product” (6%), “finding the advantage and disadvantage in the design of present product “ (8%), “ being the design reference for the component items” (8%)、” making sure the design brief “ (39%), “improving the present design” (12%) and “taking the advantage and discarding the disadvantage from the present design” (27%). The experience-based knowledge to help the designer to find the problems and needs of product ,especially to make sure the design brief , and the accumulated knowledge could be the reference for assessing suitability in design while improving the present product design, to conform the design feature necessity of existing, and let designer to know the real operation in every product feature.
2.The varying experience-based knowledge creating the difference in application the experience-based knowledge: the varying knowledge degree designers arouse the different structure of experience-based knowledge while facing the design problem, even though in the same structure of knowledge, the designers also have he different inspiration and insight for design problem along with the different knowledge degree.
3. The influence in the design development from the varying product knowledge degree:
（1）The design approaching strategy: the designer’s design approaching strategy, who with the most product using experience ,is in “function” field, and the more understanding product designers’ reason for judging his design being popular is also in “function” field. But both of them with the product using experience, the “used” group is more emphasize on the “ esthetic” field than “using” field.
（2）The self-appraisal for design achievement: the high degree experience-based knowledge designers have the more confidence for his design being popular in market than the low degree ones.
4.There is more influence in the experience-based knowledge than subject knowledge for the design development, such as in the design approaching strategy and the confidence for the design being popular in market, the experience-based knowledge is more influenced.
5.The higher degree of experience-base knowledge designers apply the more shaving and electronic razor using experience knowledge in design processing, and apply more experience-based knowledge in the listed popular design features of the sketch, and have more satisfaction for the design achievement. It shows the designers design the product which be used before they are more easier to be satisfied with the design achievement and have more confidence for the design being popular in market.
