Diagramming languages are heavily used in design and system analysis. Different languages have varying impacts on the effectiveness of designers. The author believes that there is no appropriate diagramming tool that is of substantial benefit to designers, especially in the early, pre-geometry stages of product development. A new tool, design schematics (DS), is introduced to fulfill this need. The general benefits of diagramming are outlined and the potential of diagramming tools is explored. Advantages and disadvantages of some existing diagramming methods are discussed. Analysis of diagramming methods motivates the development of DS. DS is consistent with the generic design process developed by Salustri. Several interrelated examples demonstrate how DS can capture important information during design stages. A detailed example of a coffee maker is carried out. It is executed as if the author were actually designing a coffee maker. Interrelated diagrams of the design highlight how DS helps in designing during the early stages. Computer support for development and full exploitation of DS is needed. The author believes that DS can be of great benefit to practising engineers. While there is not yet any quantitative data by which DS can be evaluated, there is anecdotal evidence suggesting that the tool has potential to be of benefit in design areas.

As we enter the third millennium, many organizations are forced to constantly pursue new strategies to differentiate themselves from their competitors. Examples include offering customers streams of new products and services, as well as continuously seeking to improve productivity, services and the effectiveness of product design, development and manufacturing processes. Consequently, new concepts, approaches and tools are emerging quickly as the globalization trend expands across the world. Product complexity, pressures to reduce production cycle time, the need for stakeholders’ contributions and multinational company as well as consumer requirements create the demand for sophisticated multi-designer collaborative virtual environments where product design can be shared and acted upon (Kunz, Christiansen, Cohen, Jin, & Levitt, 1998; Ragusa & Bochanek, 2001; Anderson, Esser & Interrante, 2003). Thus, researchers and practitioners recognize that collaboration is an essential aspect of contemporary, professional product design and development activities. The design process is collaborative by nature. Collaborative design fosters participation of stakeholders in any form during the design process. The design of a successful product is dependent on integrating information and experiences from a number of different knowledge domains. These domains include consumer (end-user) requirements, industrial designers’ professional design skills as well as manufacturers’ needs. This results in a product that performs at a functional as well as aesthetic level and that can be manufactured by the right process at the right price. End-user involvement is essential to product design, since products that do not achieve consumer satisfaction or meet consumer needs are doomed to fail (Schultz, 2001). Accurate understanding of user needs is an essential aspect in developing commercially successful products (Achilladelis, 1971). Hence, it is very important for industrial designers to gather the end-users’ needs and incorporate them into their designs. The involvement of manufacturers in the initial stages of the domestic product design process can lead to a dramatic reduction in a product’s development lifecycle time, also facilitating the coordination of the purchasing and engineering functions (Bochanek & Ragusa, 2001; Demirbilek, 2001). The increasing complexity of artifacts and the globalization of product development are changing research methodologies and techniques. A prime example of this includes the application of a virtual collaborative design environment (VCDE) for product design and manufacturing. This article focuses on the concept of virtual collaborative design. It describes a research effort to investigate cross-cultural collaboration in product development using online applications for domestic product design. The aim of this research is to investigate issues related to the virtual collaborative design (VCD) process, and to bring an understanding of stakeholder needs during the collaborative design process as well as to improve the relationships between end-users, designers and manufacturers. The article presents findings based on a survey study conducted with four different potential stakeholders: representatives of consumers, software designers, industrial designers and manufacturers.

With the rapid development of science and technology and the emergence of new technologies, the speed of product upgrading has accelerated, and the life cycle has been significantly shortened, leading to increasingly fierce market competition. Through the analysis of the enterprise product development process, combined with CAD-based product rapid design technology and parametric design technology, this paper proposes a product configuration editor based on three-dimensional software with a visual interface, and combines it with the PDM system. A software system that can be applied to actual product development is formed. Finally, the feasibility of a vehicle steering gear product design process is proved in practice. The research of this article mainly has the following two aspects of academic significance: this article describes the process of product development and design by enterprises under the mass customization production mode. After analyzing the application of CAD technology in the product design process, we studied how to use advanced design knowledge to combine specific three-dimensional CAD software for rapid product design, which can guide manufacturing companies to better carry out product design work. It is proposed to improve and perfect the initial configuration results of products in a specific three-dimensional design environment, and it can communicate with data management systems such as PDM. The configuration results can be edited and modified in the 3D design environment, and when specific parts need to be modified and designed, the parametric module embedded in the 3D design software can be used to design directly, avoiding multiple heterogeneous systems switching back and forth between, shorten the development cycle. In addition, for enterprises, the research in this article is also of great application significance.

This paper investigates metrics to predict performance and creativity of final products at the early stages of product design, i.e., at concept selection and proof-of-concept (POC) prototyping. Three deliverables (concept sketches, POC prototypes, and final products) in a project-based design class are evaluated using Creative Product Semantic Scale (CPSS). Then, CPSS scores are analyzed using correlation analysis to find CPSS of concept sketches or POC prototypes that significantly correlate with CPSS or performance of final products. The preliminary results of this paper indicate that CPSS subscales may be used to predict performance and creativity of final products; that the earlier the stage of the design process is, the more difficult it is to predict performance of final products; and that building fully-functional prototypes is important to test performance of design concepts.

A major challenge in industry today is to reduce the cost and cycle time in product development while maintaining enough flexibility to adapt to changing markets. Businesses are requiring more and more flexibility in order to produce custom goods at low cost. A new strategy called the Product Design Generator is presented to provide flexible product platforms through an automated design process where product variation is built into the product development process and is achieved through scalable and in some instances modular parametric models for a given product platform embodiment. A case study of web-based Product Design Generator is presented. The axial turbine disk Product Design Generator demonstrated cycle time reduction from 500 man hours to 15 minutes. This new product development strategy has demonstrated the potential to provide engineers the ability to study more potential design solutions, reduce the number of opportunities to introduce error in the product development process, and allows companies to apply a consistent design process across the organization.

Current trends in product development process highlight the increasing adoption of digital data and virtual processes. Nowadays, a huge amount of product data are collected without a clear management strategy and, oftentimes, they dont even cover the whole product development process. A global and integrated planning about information needed to sustain product design process is not a trivial task and, usually, companies underrates this issue. From the perspective of virtualization of processes, and then their automation, the lack of structured knowledge is certainly awful. This paper aims at making a critical analysis how product data evolve throughout the product design or configuration process and how they impact the product development activities. Efficient digital product twin allows companies to virtualize processes and leverage their automation, but it is important to understand how the knowledge management should be carried out. Three case studies, directly experienced by the authors, have been investigated analyzing digital data and virtual tools that allow companies to automate the design process, each one bringing a peculiar perspective of the problem.

AbstractWith the rapid development of digital technologies, products connectivity is increasing as well as the data produced and collected. Forecasts on product development predict that this trend will keep on growing. In this context, new design solutions based on data are emerging. Those data-driven design approaches are common for identifying the customers' need when developing a new product. However, few studies cover data-driven design in the other early stages of product design. Thus, the research question addressed in this paper is: what are the challenges of data-driven design research in the early phases of the product development process? Through a literature review and a workshop proposed at the conference DESIGN 2020, this paper offers a first glimpse of future research leads. A list of 5 challenges for data-driven design in the early stages of product design is proposed and ranked from short term to long term.

The product development process is a series of asynchronous process steps in which the geometry, the materials, and the manufacturing processes are defined to meet the performance and cost requirements. During the product design, information about a product is initially sparse and becomes more detailed as the process matures. In this paper, we apply a systems complexity analysis methodology to track the evolution of information complexity for several design process workflows. We used a frame-slot based model to store parametric design information, defined the size and link complexity measures for the design information and tracked the evolution of the knowledge-base complexity throughout the design process. Product design through injection molding is taken as an example to illustrate the utility of our approach and the static and dynamic aspects of the complexity of design information are analyzed.

 Abstract – This paper introduces a top down, system-engineering approach to develop a quantifiable and systematic tool, referred to as Design Readiness Level (DRL), to gauge design at each stage of product development. It is developed to facilitate communication between different stockholders of a design project and to address the complexities arising during all the phases of product design, from initiation to completion. The design process as one of the pillars of DRL has been studied thoroughly and is categorized into nine stages to reflect the technical flow in product development. The design stages are iterative at any level from 1 to 9 and have distinctive deliverables at the end of each stage. The deliverables simplify and characterize the assessment of the design from the technical point of view. Developing a comprehensive DRL metrics that encompasses all the stockholders’ perspectives in a design is a work in progress.
