This research puts forward a novel knowledge-supported design process for obtaining personalized ready-to-wear garment products aimed at consumers with atypical morphology by using a virtual a three-dimensional-to-two-dimensional (3D-to-2D) design method. The proposed design process starts with designing a personalized garment block, which is then extended into the desired ready-to-wear garment style. The garment block is obtained by using a virtual 3D-to-2D design method. The extension and sizing of the garment block pattern into desired ready-to-wear garment patterns is performed in a 2D environment using classic methods. The proposed design solution begins with a personalized garment block, thus avoiding the complicated operations of simulating a 3D garment directly in the virtual environment. The proposed design process can be fully digitalized, which ensures the involvement of the consumer throughout the design. By repeatedly running the sequence of Design – Display – Evaluation – Adjustment, which is technically accomplished through the virtual 3D-to-2D design method and 3D virtual try-on, the designers’ patterns and principles of elaborating personalized garment products can be validated within a very short time. As a knowledge-supported design process, designers’ design ideas and principles of personalized design solution can be fully extracted to enhance satisfaction of the final product. A set of experiments and case studies validated the approach and application of the proposed knowledge-supported virtual design process, and demonstrated its efficiency.

Information is transferred through a process consisting of an information source, a transmitter, a channel, a receiver and its destination. Unfortunately, during different stages of the engineering design process, there is a risk of a design idea or solution being incorrectly interpreted due to the nonlinearity of engineering design. I.e., there are many ways to communicate a single design idea or solution. This paper provides a comprehensive review and categorization of the possible sources of information loss at different stages of the engineering design process. Next, the authors present an approach that seeks to minimize information loss during certain stages of the engineering design process. The paper i) explores design process and dissemination methods in engineering design; ii) reviews prior work pertaining to these stages of the engineering design process and iii) proposes an information entropy metric that designers can utilize in order to quantify information loss at different stages of the engineering design process. Knowledge gained from this work will aid designers in selecting a suitable dissemination solution needed to effectively achieve a design solution.

With the great development of commodity economy, the packaging of goods has become an extremely important factor to get the advantages in the market competition. As to paper packaging, people are taking more and more attention on the design of Special-shaped Cartons.Limited by the three-dimensional way of paper, the carton CAD/CAM systems generally use the design process of "carton shape chose from the carton library →parameters set and modified →the 3D model established following the existing way", development for new carton shapes are still depended on the folding-test by the designer's hand. Design of the Carton Planar Structure usually has a time distance with Design of the Carton 3D Model, as a results, inconvenience to Special-shaped Carton designing was caused, and designers can not express their design ideas quickly and effectively.

To get all outstanding mechanical properties from ultra-high strength steel (UHSS) transformed into a lightweight and durable product, a comprehensive design process must be performed. The general DFMA method has been extended to get good design solutions with limited designer resources and within a relative short time period. Key steps of the extended DFMA design process are innovative brainstorming, the agile utilization of the optimization software, the heavy use of finite element analysis and fast design iteration. In this paper, the modified DFMA design method is described step by step. This method has been successfully used in the design process of the small lightweight rally car frame. The design process of the rally car is introduced as a case example of implementation of the extended DFMA.

In the early design process called conceptual design and basic design, diverse ideas of design must be obtained from global solution search under the constraint of unclear design conditions. It is difficult to apply the conventional engineering design method from the necessity of the setting of the objective function in the early design process. Therefore, in a previous study, the emergent design system, which is applicable from the early design process, has been proposed. In this study, the degree of freedom in an emergent design solution was extended, to form a method with two types of form elements: existing form elements (matrix element) and fiber form elements. To help construct the system, a differentiation phenomenon, which is seen in the morphogenesis of organisms with diverse forms, was introduced into the form generation algorithm in this system, and the relationship between the input parameters and the newly defined evaluation indexes was analyzed.

Case Based

During product design process, conventional case-based reasoning (CBR) has shown significant applications in coping with new problems by recalling and reusing solutions in old context. However, conventional CBR still lacks effective methods to assist designers in generating creative design solutions of identified problems during modification stage. To make up for this deficiency, an extended CBR (ECBR) method characterized by two retrieval stages is proposed in this paper. The former retrieval stage is aimed to retrieve the most similar source case for design reusing, and the latter one is designed to assist designers in searching for relevant function units to generate creative design ideas for final design solution. A five-tuple knowledge model of product case is presented. It includes both specific design information for design reusing and abstract function units for generating creative design ideas. To effectively organize these case information, a hierarchy knowledge model of case base is established. It consists of case type layer, product case layer, and function unit layer. A corresponding retrieval strategy is presented to deal with different retrieval goals. To improve the performance of ECBR method in modification stage, the substance-attribute-function-cause analysis model and TRIZ tools are integrated together to aid problem analysis and problem-solving of retrieved product case. Finally, a new product conceptual design process is proposed based on ECBR method and the conceptual design of a smokeless barbecue equipment is employed as an example to verify the feasibility and effectiveness of ECBR method.
