Research On Style Transformation Of Product Design Example's Visual Representation For Product Form Design Ideation

Using design example to inspire designer is a significant design method in product form design practice.Design example's visual representation and related visual experience can activate designer to explore and acquire new idea in design ideation.However,the influence of design example for design ideation has two sides:on the one hand,it can provide designer with related design information and design knowledge.On the other hand,it can lead to design fixation and prevent designer from exploring new concept.Therefore,previous studies have attempted to reduce the negative impact of design example by transforming visual representation.Visual representation is the focus of research,because of its high utilization.In design practice,design example's source channel is jumbled,and form is sundry.Designers obtain the design information and knowledge from design example rely on their own professional knowledge and experience.However,through literature review on the relationship of visual representation with knowledge visualization,design fixation,researcher found that the most of previous studies only focus on the casual relationship between design example's single representation and design output.The influence of design example's representation on the design ideation's process is not discussed deeply.In addition,there is no systematic method and guideline for design example's representation transformation and treatment.Therefore,based on design example representation's different influences,this paper mainly construct the complementary relationship between the two typical design example visual representation:photograph and sketch.Researcher proposes a method to extract the visual style feature model from sketch with the help of neural style transfer algorithm.This visual style feature model is used to transform the design example's visual representation.To test the effectiveness of the method,researcher constructs contrast experiments,organizes designers to achieve rapid conceptual design based on original design example and design example after style transformation respectively.Researcher ascertains the significance of style transformation exerts on design ideation by interview after experiment and the analysis of the difference between two experiments under the guidance of paired t-test.The results show that design example after style transformation succeed in appealing more interactions of participants and improving both quality and quantity of the design output.This method can save and reinforce pivotal design elements and morphological characteristics in design example while excluding from unnecessary interference information,extracting design knowledge,broadening design thinking and averting design fixation.Based on the above research,researcher apply the visual representation style transformation method to the high-end equipment product form design Aided design system,and output a series of feasible design schemes.In conclusion,this study explores the influence of design example's visual representation on design ideation,proposes the design example visual representation transformation method and its application scenario.It has certain theoretical and practical significance.
