This study led to the development of a parametric design method for mass-customised head/face products. A systematic review of different approaches for mass customization was conducted, identifying advantages and limitations for their application to new product development. A parametric modelling algorithm of a 3D human face was developed using selected scanned 3D head models. The algorithm was developed from a set of measurable and adjustable parameter points related to the facial geometry. These parameters were defined using planimetry. Using the assigned parameter values as input, the parametric model generated 3D models of a human face that served as a reference for the design of customized eyewear. The current challenges and opportunities of mass customized head/face products are described, along with the possibilities for new parametric product design approaches to enable rapid manufacturing and mass customization. This study also explored whether a new parametric design framework for mass customization could be effectively implemented as an early-stage new product development strategy for head/face products.

The rapid prototyping technology was introduced, including its definition, principle and characteristics. The advantages of rapid prototyping technology in new product development were analyzed. Application of rapid prototyping technology in design of mechanical parts, industrial model, medical model, ceramic products, automobile model and products based on ergonomics was discussed. The feasibility of rapid prototyping technology in product design and the optimization direction was prospected.

Quality Of Products

Nowadays,improving the quality of products, reducing cost and meeting customer’srequirements are necessary to shorten the time of new product development(NPD). NPD is used to describe the complete process of bringing a new product to market and conceptual design process(CDP) is at its early stage and has mostly changed from passive respond toaggressive one. Thus, this study proposed a practical method for CDP in NPDthrough three phases as Converting customers’ requirements to product specifications,Generating and selecting of concepts and Testing and finalizing the concepts byusing some different management-engineering techniques. Firstly, this papertried to prioritize customer’s requirements related to product by AHP (AnalyticHierarchy Process) and convert them to engineering parameters of TRIZ (Theoryof Inventive Problem Solving) in order to define the inventive principals.Next, based on QFD (Quality Function Deployment), we measured the weight valuesof inventive principals. Finally, as FMEA (Failure Mode and Effect Analysis)can analyze the weight values and reduce the sequential risk, then finalconceptual design was generated. At the end, a medical glasses was used as acase study of innovative design to validate the method and explain how thestrategies of this research for CDP.

Development Methods

Agile, and iterative, development methods for new product development are gaining in popularity under product engineers; where it initially was just applied for software development, now larger adoption takes place for product development in general. The design rules of agile development are somewhat conflicting with the guidelines of Axiomatic Design. In this paper, it is investigated why this is the case, what can be done about it, and how can the strengths of agile development be combined with Axiomatic Design to optimise methods for product design. It is shown that the methods are indeed advising on different and conflicting strategies, however, by attenuating the agile design rules in the early stage of design, and doing the same for AD in the later stage of design, best of both worlds can be combined.

New Product Development Process

Disciplined product development has been a hallmark of mature companies for many decades, resulting in shorter development cycles, reduced costs, and higher quality products. Unfortunately, these tools and processes have typically been applied in large, well-established firms, not start-up companies. In this paper, we describe a simplified new product development process for early-stage firms and its application to a consumer product in which the process was executed during a 14-month development cycle. The process consists of 15-steps in 3-phases, two decision gates, and provides a step-by-step guide for development, with specific call-outs as to what, when, and where tools such as market segmentation, platform planning, industrial design, and cost modeling should be applied. The proposed process is applied to design a new consumer product, and the case study results are discussed with specific emphasis on costs, duration, and applicability of the process and its related engineering tools. Finally, we conclude with comments on the limitations of the proposed process, potential improvements, and future work.

Front End

The fuzzy front end (FFE) of new product development (NPD) is a term that refers to the early stages of the innovation process. This paper investigates the FFE in the automotive industry and addresses the challenges of working in this phase of the innovation process, as well as the academic definition of the FFE relative to the real world. Two parts of the innovation process have been identified and characterized as FFE: the concept-work within satellite front-end departments and the work within the pre-development phase of the vehicle new product development process. It has been identified that one of the greatest challenges related to working in the FFE is developing viable concepts that will “sell” internally. Estimating and conveying the overall value of the final product in terms of costs and customer benefits are two of the key elements that make it difficult to achieve internal “buy in”. Furthermore, it is argued that the most common academic perception of the FFE seem to be inadequate since it only concerns work that ends with a go/no-go decision whether to continue into development or not. Consequently, it fails to capture early-stage development work of transformational innovations, where the decision of development has already been made and the uncertainty is related to the execution of the work — and — not the outcome. Semi-structured interviews with a total of eleven employees at seven different automotive OEMs form the basis for the conclusions made herein.
