Guiding conceptual design through functional space exploration

Conceptual design is an early stage in the product design process, which has an essential effect on the product innovation. Existing approaches for conceptual design always focus on the mapping processes, such as function–behavior–structure, function–behavior–state, or function–effect–solution, etc. The function, effect, solution, behavior, structure, and state all have influential factors in the above mapping processes. The enlargement of functional space, effect space, solution space, behavior space, structure space, state space, and problem-solving space can bring more opportunities to product innovation. This paper is devoted to functional space exploration in conceptual design. Each function has its own hierarchies and configurations, as well as each effect has its own multivariate influential factors, both of which can provide tremendous and exploitable space of creative concepts. The problem-solving space will be enlarged through the functional space exploration, which can obviously bring more opportunities for product innovation. This paper is devoted to presenting a systematic approach based on the reasoning of functional space exploration to increase opportunities for product innovation in conceptual design. A process of functional space exploration is treated as a three-step process, first transforming original function to derivative functions, then mapping these derivative functions to effects, and finally exploiting these effects to quantitative or qualitative physical quantity space. The functional design of new devices for decreasing resistance of amphibious vehicles is given as an example, which demonstrates that the methodology is obviously helpful to increase opportunities for product innovation in conceptual design.     

Personalization for Massive Product Innovation Using Open Architecture

Product innovation is creation of new concepts to plan and realize technological and functional details in the product to satisfy market and customer needs. One of the key drivers to product innovation is reactions of the product to users' needs. Product innovation needs a cognitive design method based on needs of variant users for the product personalization. In this paper, an open concept is introduced to provide ways to meet user's individual need in product lifespan. It is for industries to propose product concepts based on open sources, develop and support the product on the public capability. Using the open concept in the product architecture, called open?architecture product(OAP), can improve the product personalization leading to massive product innovation. To promote this promise of the OAP, effective methods are discussed for the OAP development. This paper introduces research on OAPs using adaptable design methods to meet product personalization. Adaptable design is based on the modular structure for product adaptability using function modules and adaptable interfaces. The proposed method provides solutions for planning modules and implementation of OAPs. Methods of OAP module planning, detail and interface design are described for transformation of product concepts into physical structures. A multiple?purpose electrical car is developed in a case study to show effectiveness of the proposed method.     

A feature-based approach towards an integrated product model in intelligent design

Conceptual design is an early stage in the product design process, which has an essential effect on the product innovation. Existing approaches for product knowledge engineering for conceptual design always focus on knowledge modelling and organization, etc. However, the traditional approach is lack of better comprehending representation and reuse of design knowledge in conceptual design. This paper is devoted to presenting a systematic effective integrated modelling approach of principle solutions in conceptual design to make the knowledge of functional design be transferred efficiently to the subsequent principle conceptual design and structure conceptual design process, and even detail design. With the introduction of the physical quantity model, feature-based representation model of function, effect, physical quantity, working principle and structure concept are put forward step by step, and then an integrated principle solution model is presented based on the generalized assembly model. The knowledge organization method of principle solutions based on physical quantities is also proposed. Conceptual design process based on integrated modelling and knowledge organization of principle solutions is presented, which discloses that physical quantity model is a bridge across functional design, principle conceptual design and structure conceptual design. The conceptual design of new devices for decreasing resistance of petroleum equipment offshore platform is given as an example, which demonstrates that the methodology is obviously helpful to increase opportunities for product innovation in conceptual design.
