Leading of product design process trough abstract process

There are differentiations from design process of products for real markets and other product design approaches. Design for real needs of markets has their own instructions. These guidelines emerge from local demands. Local experiences of product design can improve local knowledge of design. Third world design disciplines have to growth to make appropriate knowledge for our distinctive needs. It is important to study of international experiences too. These two approaches can make new visions on design knowledge. Design thinking principles are most important wisdoms for every designer to know. Design thinking as a whole knowledge of great designers manners leads other designers to human centered problem solving. Design thinking has appropriate view on something that a designer may meets in a project. Design process is one important subject in design thinking topics. The focus of this paper is on product design process that occurs in real projects. There are different processes for design products. Abstract process is one of these ways that has many benefits. Abstract processes of product design are high efficiency methods for navigate design projects direction successfully. Abstract processes are proportional with design thinking principles and purposes too. Simple structures of abstract processes are fit with design methods and tools. There are many design tools with various functions for a lot of design demands. Shadowing, Fly on the wall, Role playing, Brain storming, Card sorting, Empathy tools and Dirty prototyping are some of famous cases of these methods and tools. In this situation tools select and use for specified purposes. This structure can provide high flexibility. The ability to customization of process for diverse projects is biggest advantage of this structure. Design thinking point of view has congruence with abstract processes procedure. We study the design of two med product’s processes in this paper. These products ordered by two different Iranian’s companies. Our teams as independent designers do these projects at 3 and 5 months. Abstract and method based process that used to lead these projects reported directly. We did sketching; market analyzing, user study, solution making, prototyping and test in per tow cases. Representation of these market based processes reveals differences of classic process of product design from real one. Results of projects were acceptable. There were enough congruence between two projects process with abstract and method base processes. Design thinking principles leadership caused efficiency. In conclusion we represent new model of design process as Cup of design. In this model problem data and solutions are suspended in divergent and convergent spaces of project direction. Designer scrolling from these two spaces repetitively. There are some filters between path that filter data and solutions to generate adequate solution. The settlement of solution particles and parts check by designers for finding paramount combination. If gained combination does not have desirable properties the process of suspension, filtering and combination iterate. This model of design process shows some properties of design in real finding solution way. This is a good issue for future studies to seek relations between other forms of design representations and facts of design process.
