Design for Six Sigma (DFSS) for additive manufacturing applied to an innovative multifunctional fan

Abstract

In an increasing number of aggressive enterprise world, "time to market" concerning products has come to be a solution element because of enterprise success. There are exceptional techniques so expect layout mistakes or open products concerning the need between much less time. Among the most used methodologies in the design and setting about stability the requirements, Quality Function Deployment (QFD) and Design for Six Sigma (DFSS) execute remain used. In the prototyping phase, such is feasible in imitation of tackle the rising science regarding additive manufacturing. Today, three-dimensional stamping is in the meanwhile used as a rapid prototyping technique. However, the actual challenge that enterprise is going through is the use of these machineries for large-scale production about parts, at last viable along current HP Multi fusion. The aim of this article is to study the interactive design and engineering applied to the entire product development process taking advantage of the most modern models and technologies for the final realization of a case study that involves the design and prototyping of an innovative multifunctional fan (Lamp, Aroma Diffuser and fan) through the Multi Jet Fusion of HP. To begin with, issues related to the DFSS, the QFD and their application to identify the fan requirements are explored. Once the requirements have been defined, the modern CAD design systems and the CAE systems for the validation of the case study will be analyzed and applied. Finally, HP's Multi Jet Fusion methodology and design rules for additive manufacturing will be analyzed in detail, trying to exploit all the positive aspects it offers.

Development of an Advanced Composite System Form for Constructability Improvement Through a Design for Six Sigma Process

“…DFSS is a proactive design approach to develop a new product or process as it incorporates multiple methodologies (Liverani et al, 2019). DFSS aims to incorporate customers' needs into the product solution and to verify that new products meet the standards of environment for which they are designed (De Feo & Bar-El, 2002;El-Sharkawy et al, 2014;Hasenkamp, 2010).…”

“…Design for Six Sigma (DFSS) is a structured approach to developing new products by incorporating multiple design methodologies (Liverani et al, 2019). DFSS has the objective of determining the requirements of customers, translating the requirements into product solutions (He & Ngee Goh, 2015).…”

“…Previously, Wang et al (2016) applied DFSS and TRIZ for new network devices. Liverani et al (2019) suggested an interactive engineering design and development process using DFSS and QFD and conducted a case study of a multifunctional fan. Their results show that the DFSS can be an effective process for developing a new product.…”

Virtual Mechanical Product Disassembly Sequences Based on Disassembly Order Graphs and Time Measurement Units

“…As a result, policies have been implemented for the proper disposal of this waste through the dismantling of various disused devices; however, this activity can potentially become disadvantageous when dismantling is difficult to implement due to difficult to manage materials and design choices totally aimed at optimizing production. Many optimization methods based on QFD (quality functional deployment), TRIZ (theory of inventive problem solving), and benchmarking can support the product design from the early phases onward [1][2][3][4]. They try to convert the user's requirements into product specifications and they are useful instruments for competitive analysis and continuous improvement [5].…”

“…This has to be combined with a classification of the "EOL option," i.e., how the component will be used/disposed of once it has been disassembled from the assembly; or how to allocate the recycling of elements such as precious metals, plastic materials, and elements that cannot be used; or how to recondition processes and reintegrate into the production cycle; or how to best perform maintenance. As performed in the publications, the total value of the TMUs has been converted using the formula: Time (s) = (10 × TMU) × 0.036 (1) where 0.036 is the standard value of conversion from a TMU task to seconds. For the calculation, an Excel sheet was prepared in order to easily calculate the various amounts of TMUs.…”
