| Car interior with space characteristics,the main place to realize the functions and the user experience of automobile products,is a man-made space composed of objects.Things belong to space,and space is the way in which things exist.The research category of this thesis belongs to the field of styling design in industrial design.The styling,a way of space design,must exist in a certain space.The essence of automobile interior space design is to grasp the existing mode of styling.The research content of the paper is selected from the National Natural Science Foundation of China,the 973 project sub-project and National High-tech R&D program(863 program sub-project for the design problem),combined with several automotive interior design projects that the author participated in,focusing on the automotive interior.The main research questions in this paper,the definition,cognition and space elements of the car interior space,were investigated.The interior design of the car included many fields.This thesis mainly studied the problems on the space design of automotive interior including three research objectives: definition of the cognitive elements of the car interior space,the relationship between each cognitive element and the car interior space,analysis of the cognition the cognitive differences between designers and users for the interior space features,and constructing of the car interior space design methodology based on the relationship of space design elements.According to the principle of combining theory with factual basis,the literature research,questionnaire survey,experimental demonstration,field investigation,statistics and spatial syntactic calculation analysis were used as the practical research means in this thesis.The questionnaire survey,experimental evidence,field research,statistics and spatial syntax analysis were used as the research methods to deal with the interior space design.The main experimental examples involved in this paper were: 1)cognitive interview research of car interior space;2)cognitive difference experiment on the car interior spatial feature;3)perception experiment of car interior space layout;4)cognitive difference experiment of car interior and exterior space styling.The main projects providing data and factual basis for the research of this paper in the design practice were:(1)"SINO HOWO Medium Truck Design",(2)"SINO HOWO Light Truck Design",(3)"Aisn Electric Vehicle Interior Concept Design Project",(4)"E200 electric vehicle design",(5)"CRRC product aesthetics strategy design manual ".The main points are as follows:1.The spatial view of "object and non-object" was adopted as the space view of this paper based on the analysis of the universal space philosophy combined with the research object of this paper.By comparing and analyzing 15 classic spatial cognitive models,combined with the characteristics of the interior space of the car,the spatial relationship model of the car interior was proposed to provide a macroscopic cognitive framework for the car interior space.Through interviews with designers and users about the interior space,the results showed that both the designer and the user considered that the car interior was a closed space enclosed by the body exterior cover,the components of the car interior(the spatial feature)were the basic unit of the space composition and spatial cognition of the car interior,the seat was the most significant influence on the occupant activities and communication in the interior space,and was also the main space perception point in the car interior.Seat arrangement not only affected the activities and communication of passengers,but also affected passengers’ perception of the space layout of car interior.On the specific space cognitive path,the two groups of designer and user showed cognitive differences,and the designers preferred to generalize the related cognition because they recognize the car interior space by generalizing the various elements that constitute the interior space of the car.The user tended to be aware of the details,that is,through the recognition of several spatial elements in the car interior space to build an overall perception of the car interior space.Based on the spatial features,spatial layout and spatial form composed the foundation of interior design and space research on the composition and cognitive level of automotive interior space,a framework model of automotive interior design space was established.2.The space styling feature of automobile interior is an important carrier to convey the aesthetics of automobile interior because the feature recognition is the core of the cognitive process.By using the method of questionnaire survey and mathematical statistics,the cognitive difference between ordinary users and designers with professional background on the boundary line and feature lines of automobile interior space was studied.The results showed that ordinary consumers tended to recognize the feature lines of interior,while designers did not have obvious bias.For the recognition of boundary line and feature lines,ordinary users showed differences for these two recognitions,and designers did not express the difference between the recognition of boundary line and feature lines.A space feature recognition model of automobile interior for the users and designers was constructed,which provided the valuable reference of car interior design by the real example of interior design.Through the interior design example,it is shown how this cognitive difference affects the generation of automotive interior space in design practice.A derivation tool for the interior space feature was proposed based on the investigation on the development of automobile interior features combined with the general product attribute cognitive theory,which provided a credible vehicle interior feature generation and design assistant tool.3.The perception experiment of spatial layout of automobile interior using seven different car models with different seat arrangement are taken as research objects indicated that the layout and orientation of the seat in the interior space are the important factors affecting people’s activities in the interior space and communication between people.The styling of automobile interior was discussed by regarding the automobile interior as a "miniature" space,and the method of "space syntax" was used to study the spatial distribution of automobile interior.The J-type diagrams of eight kinds of automobile interior with different seat numbers were analyzed and the topological depth was calculated.The corresponding depth values,connection values,global integration and standardized integration values are analyzed.The relationship among these parameters,the characteristics of circulation and privacy of automobile interior space were studied.The space perception experiment of car interior layout was set up to investigate the space perception of occupants among different types o f car with different space layout.The results of space syntax calculation on the space circulation of car interior were consistent with the experimental results.The results showed that,as far as liquidity and privacy are concerned,it was feasible to use spatial syntax as an assistant tool for automobile interior design.The spatial syntax could provide a new idea and method for automobile interior design by verification of design cases.4.The cognitive experiment of automobile interior space and exterior styling provided the experimental basis for the cognitive consistency of automobile interior and exterior styling,and explored the cognitive differences on the consistency of automobile interior and exterior styling between ordinary users and designers.The connotation of the space form of automobile interior was clarified and three elements that constituted the space form of automobile interior: space scale,space tension and space expression were investigated.Spatial scale,related to spatial proportion,spatial interface treatment and volume of interior space,did not refer to the concept of physical dimension,but to the spatial dimension of automobile interior,not spatial dimension.Spatial tension,as a real and quantifiable variable of space or form,was a non-physical conceptual force,but a description of form and sensation.Space expressionwas used to describe the meaning of space and to express the intention of space design for automobile interior.Based on the analysis of the relationship between the design attributes of automobile interior space and automobile interior styling,the communication mode o f automobile interior styling and the mapping relationship of space elements was put forward,and the process framework of automobile interior space design was constructed.Two levels,"seeking truth" and "seeking utility",were used to study the car interior space design in this thesis.From the point of view of "seeking truth",based on literature research and analysis,this paper studied the space problem and defined the space category.Combining with previous studies on the space styling of automobile interior,the composition and cognitive paradigm of the space of automobile interior was suggested,and the design of automobile interior carried out from the part styling design to the space integration.For the perspective of "seeking utility",this paper constructed a process framework of automobile interior space design from the perspective of space,which provided an alternative and effective design method for designers to design automobile interior.This framework includes the design tools、models and theories proposed by the materialization of design information.From this point of view,this framework was also an operable assistant tool for designers in design practice. |
