AbstractInformation Technology (IT) and the process of new product development (NPD) have become completely intertwined. From computer-aided-design (CAD) to video conferencing to traditional tools like email, the act of design, iterating and communicating with team members is touched at every point in the process by IT. Over the last ten years, new, collaborative information technology (CIT) has entered into the NPD process to make the activity of communication and team information sharing easier, more frequent, and distributed. What is not known is how these tools are influencing the design process itself. This research uses a longitudinal multi-method, ethnographic approach to deep dive into actual use cases. Our results indicate that CIT can have a substantial impact on NPD, but does not automatically alleviate traditional problems during NPD. We also find that the propagation of tools via new firms startups has developed a single tool per task paradigm, which is counter to the development of complex platforms offered by established firms. These single use tools are easily adopted but also easily discarded by development teams.

In recent years, rapid prototyping (RP) technology has been implemented in many spheres of industry, particularly in the area of new product development. Rapid prototyping has the capability to produce a tangible solid part, directly from three-dimensional computer aided design (CAD) data, from a range of materials such as photocurable resin, ceramic and metallic powders and paper. However, in most cases, models built in acrylic-based resin in the stereolithography (SL) process have not yielded the desired quality, which has led to a shift in the use of this resin to more expensive ones that have longer build time. An experimental investigation has been carried out to determine statistically the optimum build parameters with the use of the Taguchi method in order to improve the SL product quality. Two new hatch styles have been developed in this study and a confirmation experiment has shown a significant improvement in part accuracy.

This article discusses the evolving trend of mobile applications and their increasing use by engineers. With the help of mobile applications for smartphone and tablet, engineers are discovering innovative ways to work that don’t have them tied to their desks. Apps allow engineers to bring drawings with them while on the road, to collaborate with other engineers, and to access information on the shop floor or in the field. Due to the very nature of the mobile platform on which they sit, applications can’t be used at every job. Their adoption depends on the type of work, the work environment, and employees’ attitude. If enough employees do have their own personal devices, there are apps that let employers update employees on the shop floor or in the field. Many engineers use mobile applications to collaborate with their design-team members or to show others, like customers or suppliers, how a product will look or will function. Engineers can also share computer-aided design drawings, design work, spec sheets, and the like through the technology.

Problem-based learning (PBL) approaches are well-accepted and disseminated and have been intensively employed in several engineering programs. This article aims to present a teaching experience in which PBL was applied in one course of a mechanical engineering graduation program. The PBL approach applied is described step-by-step as well as the goals and constraints related to Computer-Aided Design, Engineering and Manufacturing (CAD/CAE/CAM) technologies employed in this particular case. The evaluation process is described, as well as the quantitative results, and also the results obtained from questionnaires answered by the students at the end of the PBL experience. Additionally, the team’s technical success in solving the proposed CAD/CAE/CAM problems was also taken into account. This PBL approach provided the students with the required autonomy to develop their argumentative skills within the team, defending their ideas, and at the same time, promoting self-criticism and ethical and impartial judgment among the other team members.

The problem of efficient design of roofs is a topical area of research. This is confirmed by scientific studies [1–5, etс.]. Today, in the times of information technology in all areas of actively using the computer and specific programs [6; 12; 15, etc.]. The author presents a proposal of geometric design (geometric solutions) for roofs with restrictions, so-called "roof with its neighbors."Roofs are treated as a special class of polyhedral surfaces. Construction includes a corresponding attachment roof with restrictions on the roof on a simple connection of the polygon, designing a conventional roof and perform the appropriate logic operation. Fig. 1. The Boolean operations are useful tools in geometrical designing of roof skeletons. Solving roofs with neighbors is much easier if we bring them to solve simple roofs over simpleconnected polygon base. The difficulty comes to the design of an appropriate polygonal base. This method essentially involves applying geometric design of a regular roof to design a roof with constraints, which can be relatively easily performed with a CAD program [13]. The elements of a roof: a) a roof with its elements in the orthographic projection, b) the roof with its elements in a military axonometry, c) the line of disappearing ridges of the roof in the orthographic projection [9].

The Relationship

PurposeThe size prediction of garment is an important part in the process of the garment design and production, and it is also one of the most important features in warp-knitted computer-aided design system. The purpose of this paper is to realize the auto-generation of the garment templates using JavaScript and WebGL technologies, based on the prediction of the size of warp-knitted seamless sportswear.Design/methodology/approachThe warp-knitted jacquard technology is used to produce the warp-knitted seamless sportswear, which is divided into suits and tights. In order to achieve the purpose of this study, the dimensions of four kinds of jacquard patterns knitted under different knitting conditions are measured and the crosswise and longitudinal size shrinkage percentages are also calculated. Then, the relationship between the yarn count and the drawing density as well as the size shrinkage percentage is studied and a size prediction model for warp-knitted jacquard fabric is established. Next, according to the results of the size calculation, the point positions of the garment boundary in the mathematical coordinate system is determined. The color formula is built by the two-dimensional mathematical matrix. Finally, combined with the coordinate position and color information, the template can be drawn automatically.FindingsBased on the size prediction model of warp-knitted garment, the template generation of warp-knitted full-form sportswear on WebGL-enabled web browser is realized, which is proven to be an effective computer-aided design method for warp-knitted garments.Research limitations/implicationsBecause of limited researches, only two groups of yarns and four kinds of jacquard patterns were studied. A vaster database should be built and smooth curve, accurate coordinate needs to be optimized in the further research.Practical implicationsThe size prediction model for warp-knitted jacquard garment and garment template auto-generation of warp-knitted computer-aided design system will simplify the fabric technical design process, shorten design time and improve the efficiency of new product development.Social implicationsThe size prediction model for warp-knitted jacquard garment and garment template auto-generation of warp-knitted computer-aided design system will provide the industries a guidance for new sample development and it also can shorten the development time and lower cost.Originality/valueThis author analyzes the relationship between the size characteristics and knitting technology of warp-knitted jacquard patterns, proposes a model of size prediction and realizes the auto-drawing of the garment template in the warp-knitted CAD system, which provides a reference for the new product design and development of warp-knitted seamless sportswear.

AbstractThis paper analyses the use of information and communication technologies (ICTs) in a distributed product design project-based learning (PBL). The paper presents the ICT use of five international student teams during three product design phases: identification of opportunities, conceptual design, embodiment design. General results show that student teams used around 30 different ICTs for both taskwork and teamwork. Students reported that they used previously known ICTs or ICTs properly introduced to them during the initial course workshop. Results also show that team members often work individually on their tasks and use various procedures to share their results. Also, teams conduct some activities synchronously, suggesting the need for teams to have a collaborative workspace. Cloud-based collaborative ICTs (e.g. whiteboard, computer-aided design, document editor, task management) showed huge potential for individual and team tasks. Hence, educators and teams should carefully consider which ICTs to implement and learn, as it might greatly impact the execution of the product design PBL course.

Lost In Translation

This article explains how software and networked information sometimes become a problem for mechanical engineers. Many mechanical engineers find themselves deeply challenged by their digital work environments. Supposedly created to relieve them of tedious and repetitive work, the ubiquitous computer systems all too often thwart collaboration among engineers. The variety of data involved in computer-aided design, simulation, and analysis is overwhelming. New-product development regularly presents translation challenges, starting with sophisticated geometry such as blended surfaces and variable-radius splines. Graphic formats also advance steadily. Software developers regularly update graphical user interfaces and enhance their data-capture capabilities. Because each drawing and its information are used again and again, every engineer who imports files into a new system has to choose between modifying as necessary and recreating them keystroke by keystroke. Recreating means that the original cannot be trusted and can entail an enormous waste of time. Manipulating information from one format to another is tedious and stressful, with big opportunities for error.
