AbstractProduct variant design, as one of the key enabling technologies of mass customization, is the transfer of variant information among mating parts from the perspective of informatics. A dimension constraint network (DCN) among mating parts carries on the task of transferring variant information. What are the information transfer characteristics of dimensions in a constraint network is a fundamental issue to plan the product variant design process reasonably. We begin by showing the natural dynamics of the DCN from two aspects: structure and uncertainty. The information efficiency of the DCN was proposed based on its simple path to specify the information transfer capability of the network. Based on this, the information centrality of the dimension was developed by measuring the efficiency loss of the DCN after the removal of a dimension from the network, which describes the information transfer capability of this dimension. Further, the information centrality of a part was derived. Using a spherical valve subassembly, we calculated the information centrality of the dimensions in a constraint network. We determined that the information centrality of dimension is highly correlated to its out-degree. An approach to plan the sequence of the part variant design according to its information centrality was proposed. We calculated the uncertainties of the DCN and its cumulative uncertainties under different sequences of the part variant design. Results indicate that part variant design under the descending information centrality of the parts minimizes the uncertainty of the DCN. This suggests a new method of planning the sequence of part variant design.

Product Dimension

In the current market demand of rapid response manufacturing, the product variant design technology is one of the key technologies. Product variant design principles and methods are first described. Then, product dimension parameter is analyzed and product dimension parameter transferring structure is studied. Applying tree theory to product variant design, a dimension relation driving-tree of components and parts is constructed and the significance of driving-tree statistics and a dimension parameters transfer method are presented. The methods and processes which are applied to variant design and the sorting algorithm of relations are described in detail. A parameterized variant design module integrated with SolidWorks was developed with VC + +. All the above mentioned methods and processes are verified by taking a joint coupling product as an example.

Product Variant

To enhance the ability and reliability of product variant design, an object-oriented framework was constructed using an extensible module/product class for setting up a modular design model. A module/product in a class was identified as an object by encapsulating the involved information as properties and the transforming or interaction activities as operations. This extensible object was gradually optimized through communications with other objects and integrations of design knowledge in five domains. These include Customer, Functional, Physical, Process and Engineering, which is a new domain introduced in this paper. The programmatic framework was implemented and successfully demonstrated using some typical machine tool products.

PurposeProduct variant design can only be achieved after all its constituent parts have been implemented by variant design. It is necessary to plan the sequence of part variant design reasonably. The product variant design process involves a large amount of information transfer events at the dimensional level. A reasonable product variant design process needs to make full use of the information transfer characters of parts to decrease the uncertainty of product variant design process. The existing methods of researching the product variant design process mainly focus on resource constraint and activity logic. They are deficient, however, in information transfer resolution and uncertainty management. This paper aims to address these issues.Design/methodology/approachThis paper identifies the number of dimension transfer paths and the position of dimension locating within a transfer path as being the key factors affecting the information transfer role of dimension. Information transfer utility is proposed to measure the information transfer capability of dimensions and parts. Based on these, a two-stage approach of generating the sequence of part variant design based on information transfer utility is proposed.FindingsThe uncertainty of dimension constraint network is minimal during the product variant design process when parts are implemented by variant design under the sequence generated through a two-stage method based on the information transfer utilities of parts, as does the times of parameter transferring and iteration in dimension constraint network.Originality/valuePart variant design under the sequence of descending information transferring utilities can decrease the difficulty of implementing product variant design validly and also increase the efficiency. This suggests an innovative method to planning the product variant design process reasonably from the perspective of informatics.

Modular Method

Variant design is the main form of most manufacturing enterprises. In this paper, an extensible modular method is proposed to enable better and faster design. The structure module is set size inner-related, and then when the user requirements change, the key structural variables can be adjusted followed by the alterations of the driven sizes, also these alterations can be verified by the engineering analysis. Therefore, the product variant design process can be preceded effectively with the extensible modules.

Product variant design is one of the key technologies of Manufacturing Enterprise for responding market demand. During the product variant design, tolerance variant design plays an important role. However, tolerance variant design is considered rarely in the researches of product variant design. To solve the problem of tolerance design in product variant design, a component variant design method integrating dimension and tolerance is presented in this paper. The fundamental and implement of component dimension variant design is introduced. Through analyze the conventional tolerance design method; the status for tolerance variant with its implemental dimension is marked as fixed tolerance value, fixed tolerance grade and tolerance value variant with special regular. The equation of dimensional tolerance variants with the value of implemental dimension is presented. So the procedure of component variant design method integrating dimension and tolerance is proposed. Finally, a case study of output shaft of reducer illustrates the implemental process of proposed method. Result comparing with conventional method shows effectiveness of proposed method.
