TRIZ approach for designing a new assisted tooling for dimple structure fabrication / Mohd Nor Azam Mohd Dali...[et al.]

TRIZ is a systematic means or tool that provides a logical approach to solving problems through inventive and innovative manners. This research shows the TRIZ approach implemented in demonstrating the need and necessity for developing the design and concept of assisted tooling, which is relatively new, in fabricating a dimple structure for the turning process. Based on the analysis using TRIZ, a structural design and concept of linearly speed movement assisted tooling was developed by using low cost mechanical components that are readily available and easily purchased in the market. Movement of the tool holder was in the x direction with the help of a DC motor connected to a cam system to move the tool holder. The factors for selecting this concept of structural design in this research were based on low component cost, efficiency, performance, durability, minimum use of supportive components, and a simple design installation which can be mounted on a tool post and turret without redesigning the tool holder and, therefore, minimised the cost of fabrication

Natural Language Processing in-and-for Design Research

We review the scholarly contributions that utilise Natural Language Processing (NLP) methods to support the design process. Using a heuristic approach, we collected 223 articles published in 32 journals and within the period 1991-present. We present state-of-the-art NLP in-and-for design research by reviewing these articles according to the type of natural language text sources: internal reports, design concepts, discourse transcripts, technical publications, consumer opinions, and others. Upon summarizing and identifying the gaps in these contributions, we utilise an existing design innovation framework to identify the applications that are currently being supported by NLP. We then propose a few methodological and theoretical directions for future NLP in-and-for design research

Using Ideation Tools for Face-to-face Collaboration Within Complex Design Problems

The focus of this research are ideation tools and their ability to catalyse ideas to address complex design problems. Complex design problems change over time and the interactions among the components of the problem and the interaction between the problem and its environment are of such that the system as a whole cannot be fully understood simply by analyzing its components (Cilliers 1998, pp. I). Ideation for this research is defined as a process of generating, developing and communicating ideas that are critical to the design process (Broadbent, in Fowles 1979, pp. 15). Based on Karni and Arciszewski, who stated that ideation tools should act more like an observer or suggester rather than controller or an expert, I defne design ideation tools as tools or methods that enhance, increase and improve the user's ability to generate ideas with the client (Karni and Arciszewski 1997; Reineg and Briggs 2007). Based on a survey of over 70 ideation tools, protocol analysis of design activities, a web survey and semistructured interviews, I conclude that designers and clients may not have sufficient knowledge of ideation or ideation tools in either testing or practice as a catalyst for generating possibilities and that measuring ideation tools based on how many ideas they generate is misleading because it relates creativity and idea generation but does not adequately reflect the participants' experience. This research suggests that participants' cultural perceptions of design ideation and the design process actively inhibit idea generation and that a shift from design outcome led ideation tool design to designing ideation tools that engage design contexts are necessary to effectively address complex design problems. This research identifed a gap in ideation tools for designers to collaborate with their clients during the ideation phase to catalyse possibilities to complex design problems as the contribution to new knowledge

Review on recent advances in information mining from big consumer opinion data for product design

In this paper, based on more than ten years' studies on this dedicated research thrust, a comprehensive review concerning information mining from big consumer opinion data in order to assist product design is presented. First, the research background and the essential terminologies regarding online consumer opinion data are introduced. Next, studies concerning information extraction and information utilization of big consumer opinion data for product design are reviewed. Studies on information extraction of big consumer opinion data are explained from various perspectives, including data acquisition, opinion target recognition, feature identification and sentiment analysis, opinion summarization and sampling, etc. Reviews on information utilization of big consumer opinion data for product design are explored in terms of how to extract critical customer needs from big consumer opinion data, how to connect the voice of the customers with product design, how to make effective comparisons and reasonable ranking on similar products, how to identify ever-evolving customer concerns efficiently, and so on. Furthermore, significant and practical aspects of research trends are highlighted for future studies. This survey will facilitate researchers and practitioners to understand the latest development of relevant studies and applications centered on how big consumer opinion data can be processed, analyzed, and exploited in aiding product design

Eco-Design Improvement at the Conceptual Design Stage: Methodology and Applications

While quality tools are familiar to industries for the continuous improvement of products, the associated tools can be adopted to make significant contributions that address environmental concerns. This aligns eco-design with the product improvement process. This thesis proposes an eco-design improvement method, in which the eco-design tools are systematically integrated for the purpose of reducing environmental impacts. In this context, this work focuses on the adaptations of quality tools for supporting the generation of new eco-design concepts. The developed methodology consists of three major phases. The first phase is concerned with the development of a relational matrices model. This phase is intended to explicitly capture the information of an existing design via relational models. These models are based on the integration of quality function deployment (QFD) and functional analysis (FA). The QFD process requires mapping quality attributes and design attributes to identify the attributes’ relationships to the existing design. The integration approach used is based on developed relational matrices to capture the relationships among environmental requirements, engineering metrics, design functions and physical components. In addition, FA focuses on functional decomposition of a design to support the generation of design concepts. One important feature of this phase is to connect the environmental requirements to the design functions. The second phase is concerned with the generation of design concepts. In this phase, after identifying the functions that are responsible for reducing environmental impacts, a morphological chart is used to support the synthesis of new design concepts. The third phase considers environmental impact assessments and concept selection. In this phase, two methods are developed: Pugh chart and fuzzy assessment. The Pugh chart is intended to evaluate the newly generated concepts via the delegated engineering metrics. As well, fuzzy assessment is intended to capture the imprecise design information at the conceptual design stage. To address this research problem using fuzzy assessments, the trapezoidal fuzzy numbers are first applied to capture imprecise design information for each design concept. A decision guide is also proposed to suggest a course of action based on the results of fuzzy assessments. This phase is also concerned with ways to incorporate such imprecise information with eco-indicators for decision making. Finally, for the demonstration and validation, the proposed methodology is applied to three case examples. These examples are in two different contexts. The methodology is first applied to home appliances, which are a coffee maker and hair dryer. Then, the suggested methodology is extended to the forming processes, specifically, the diaphragm forming process (DFP). This application of the diaphragm process is demonstrated through the assessment of the energy consumption of the usage stage. The developed methodology illustrates potential reduction in energy consumption for the generated designs of the applied examples. The results show the applicability of the proposed methodology

Development of Dynamic Assisted Tooling Using TRIZ Approach for Dimple Structure Fabrication in Milling Process / Sharudin Hassan...[et al.]

Most processes used for dimple structure fabrication nowadays have side effects on environment and human, high consumption of energy and high costs of machine set up. In order to solve these problems, Theory of Inventive Problem Solving (TRIZ) approach has been used to identify the appropriate process and technique to fabricate dimple structure on a flat surface. This method is chosen due to its advantage in terms of time saving and cost reduction for selecting the appropriate technique for fabricating dimple structure. Result analysis on TRIZ approach proved that milling process is a suitable technique to fabricate dimple structure on a flat surface. An assisted tooling is required to assist the dimple structure fabrication using a milling process. Prototype Dynamic Assisted Tooling Milling (DATM) has been successful developed to fabricate dimple structure
