morphological analysis in product design

First, the total volume to be removed by machining is obtained by subtracting the part from the stock. Under this new paradigm, product information needs to be shared flexibly to meet collaborators’ requirements. Note that as the TBDA approach is intended for use in industrial practice, the approach is independent of specific engineering design and product development processes utilized in industry. Morphological matrix for exercise product. A gap exists in scientific studies on categorizing different architecture interior forms according to design. The remnant of each additive feature is then decomposed into swept bodies and non-swept bodies. If engineering designers have to send every solution candidate to a design analyst, a lot of time and money is lost. Efficient modelling of many problems in the finite-element analysis of structural and other continuum problems requires substantial simplification of the design geometry. Finally, the proposed method is applied to a problem investigating the design of architectures of detection systems for the protection of homeland critical assets. MA was first proposed by Zwicky (1948) and has been widely applied in product design, ... MA has been applied in many fields: jet and rocket propulsion systems , computer-aided design modeling (. These combinations could provide the full range of customization of product partitioning involve in product design, ... Other unoccupied configurations also have possibilities to become opportunities, although they need more refined research activities with comprehensive industrial survey (Klevorick et al. 1988. p. 237–43. This paper presents a methodology for categorizing interior forms of built places. The tool provides an easy way to make computer-aided design model modifications implied by the analysis results; thanks to features parameterisation and a reconstruction process. Several concepts are developed in a virtual environment and four alternatives among them are realized using Additive Manufacturing. 4 HOURS - 1 DAY. In the wide application of finite element technology, models with complex geometric information would cost large amount of computing resources. 1.11 - Like the scaffolding in a building project, a... Ch. However, there is a wide range of such requirements. The applications of GMA are far wider. We further demonstrate that the only proposed theory of tolerances in solid models, and the current dimensioning and tolerancing standards in industrial practice, are both inadequate for dealing with VBRs. The future success of CAD and CAM depends on the ability of these two processes to communicate with each other and with the intermediate manufacturing database. The results showed that females provided larger pupil diameter in pleasant and neutral product images but a smaller pupil diameter in unpleasant product images than that provided by males, which is consistent with the result of subjective ratings. At the recognition stage, the algorithm constructs an attributed adjacency graph, which is then enriched with such information as edges’ types, their properties, and the assumed kinds of blend faces. A case study is used to verify and illustrate the effectiveness of the approach. Appropriate displacement and remove strategy towards geometric features in original model is researched in order to generate model states whose theoretical results equal their original model's for the purpose of evaluating the value difference between computing results of the original model and its model states. The description of an object as an initial gross shape that has been successively modified by the adjunction of form features enables a hierarchical idealisation of the object through simple and fast processes. Principles of Morphological Analysis 4:33 Product. On the basis of genetic algorithm integrated with back-propagation (BP) neural networks, taking the mobile phone as research object, an optimization design algorithm was finally designed. In other words, MA systematically categorizes the possible combinations of subsystems. The execution is controlled by a moderator. The experimental study was conducted with the example of goblet. This method can be used as part of an adaptive process of geometric simplification. Journal of CAD/CAM and CG 1997;12(1/2):17–32. Product analysis can be carried out by: 1. Keywords: General morphological analysis, non-quantified modelling, engineering design, scenario de-velopment, policy analysis, product design, design theory, technological forecasting, Fritz Zwicky. and fuses the faces using energetic method. Such conversion is of particular importance for the support of concurrent engineering, in which several engineers from different disciplines work simultaneously on the design of a product. This paper concerns the origin of features, and their role in an intelligent design-with-features system. MORPHOLOGY • The study of word formation – how words are built up from smaller pieces. A method has been developed that decomposes a curved object into volumes, called maximal volumes, with the half-spaces of the object. The clustering analysis grouped all the images into 25 clusters with the highest internal and the lowest external similarities. The various functions and subfunctions of a product can be established through a function analysis (see ‘Function Analysis… The author identifies several transformation/mapping mechanisms, and Morphology 1 addresses the innovative aspect of product design. The main advantage of the proposed method is that by considering one face at a time rather than the whole component, the complexity of the problem is reduced drastically. Issues related to feature-feature interactions are identified and the types of interactions classified. designers in performing CBDA singlehandedly, or in any other organizational setting, by utilizing a Template-Based Design Analysis (TBDA) approach, as an integrated part of their activities within the engineering design process. Abstract: Identification and systematic analysis of managerial problems related to both product design and manufacturing are considered. Extraction multi-vue des formes carac-teristiques. Automatic feature detection that is generic and easily extendable is a key element needed to achieve these objectives. Service Design. Taking users’ emotional needs into consideration, this research aims to propose a new method to present product design features exactly and completely. In this paper, an intermediate feature representation based on B-rep entities will be addressed for a feature conversion architecture. 2. Many existing defeaturing methods typically resort to syntactic pattern recognition or similar approaches to first recognize the features on the solid body represented by B-rep or mesh and then remove them and heal the gaps. Small and irrelevant features are first recognized in the input mesh or Brep CAD model and are removed manually. The main innovation of this study was to evaluate the architecture interior forms of real built places as a base for any analysis on form. The internal representation of the solid modeller provides a description of parts which when used directly is useful for automation of the process planning function. The descriptive features of each cluster could show its formal characteristics. These definitions are used as the basis of a suite of functions to support feature modelling. This way, more complex interactions may also be captured and more realistic scenarios may be defined. IFIP interna-tional conference on feature modeling and recognition. The method presented herein serves to compute an a posteriori indicator for the purpose of estimating the significance of each feature removal. In the modern data-rich economy, understanding mechanisms and related factors of data-based value creation in IISs is essential for using IT to improve such services. In order to prove the applicability of the proposed methodology, corresponding operators are developed and successfully tested on industrial use-cases. This tool is based on a morphological analysis of the solid model followed by a two-phase process: simplification and idealisation. If the nailer was a powered by compressed air then we would have to use industry-standard nipple to accept the compressed air. After the Euler operators are done, the affected edges are reconstructed to obtain a watertight boundary representation of the model. Keywords: General morphological analysis, non-quantified modelling, engineering design, scenario de-velopment, policy analysis, product design, design theory, technological forecasting, Fritz Zwicky. To reduce the computational burden without sacrificing accuracy, it is customary to design a set of relevant scenarios. It is visually recorded in a morphological overview, often called a ‘Morphological Chart The approach holds promise to strengthen information support systems for commercial enterprises in technical innovation and market innovation activities. Intelligent mechanical computer-aided design systems will need to reason about the topology and geometry of designed artifacts. In-depth, contextual interviews combined with generative techniques allow us to uncover what is at work deep down in customers’ minds. This study aimed to explore the correlation of interactive visual/hearing interface with users' emotion. This paper presents a form of features based tool to aid the integration of analysis during the design process. decision-making, systematic approach, systems engineering, engineering management, organization. A morphological chart is a visual way to capture the necessary product functionality and explore alternative means and combinations of achieving that functionality. This dissertation contributes on enhancement of the decision-making process by structuring and managing design activities in complex technical organizations. This approach extracts a construction graph from B-Rep CAD models so that the corresponding generative processes provide meaningful volume primitives for idealization application. To resolve this problem, this study suggests a way to control effectively the LOD of large-scale B-rep assembly models. Templates are also utilized for QA (Quality Assurance) and monitoring of the analysis activities. An encryption based partial sharing approach for CAD models has been developed and presented in this paper. The algorithm allows for extensions through adding descriptors of the new topology situations into the processing. A morphological approach to product design is proposed that consists of two related morphologies. 5:11. The results support the applicability of Design Heuristics to student idea generation in biomedical engineering design. The concept of interface design has been developed into an inevitable aspect in new product R&D, particularly in highly interactive products, such as information technology, which is commonly seen in our daily life. In this approach to form-feature recognition, volumetric form features which are intrinsic to the shape of a given object are recognized from the boundary information through ASVP decomposition. In line with it, this paper aims to propose a hybrid approach based on morphological analysis (MA) and unified structured inventive thinking (USIT) for technology opportunity discovery (TOD) through patent analysis using text mining and Word2Vec clustering analysis to explore the intrinsic links of innovation elements. Finally, the analysis features and their relative interfaces are generated, which ultimately gives the corresponding analysis feature model to the input design feature model. To systematically collect the business model patterns, we have collected a set of predefined building blocks which can be used in business modelling. Virtual prototyping technology is consistent with the characteristics The aim is to propose a framework to address complex systems in two stages: first, formulation and generation of alternatives through general morphological analysis, and second, improvement and integration with design structure matrix for sequence optimization and cluster analysis. the agile modeling ideas. Second, a BP neural networks model between design variables and user preference along with Kansei image words was established and verified with questionnaire survey data. It allows producing an analysis model out of a part solid model. In this chapter, an innovative customized encryption approach to support product development collaboration is presented. The catalytic surface needs to break the scaling relations between the intermediates (47, 52, 53). A function analysis of the product that needs to be designed forms another starting point: the product should be described in terms of function and subfunctions. 1995). Computation of the midsurface has been observed to be effective when the original model is defeatured to its gross shape. This tree structure is used to highlight symmetry properties in the object but it neither provides a CSG tree nor primitive entities that could serve as basis for idealization applications. The eye movements of participants were measured while viewing product images. Geometric computation for the recognition of spatially interacting machining features Advances in feature-based manufactur-ing. The procedure consists of searching the part description, recognizing cavity features, extracting those features as solid volumes of material to be removed and arranging them in a feature graph, a high level data structure appropriate for manufacturing process planning. In addition, we determine the probabilistic moments of the stochastic solution that satisfy the given accuracy requirement by expanding to n th order. This study identified nine key factors that characterize this data-based value creation: (1) data source, (2) data collection, (3) data, (4) data analysis, (5) information on the data source, (6) information delivery, (7) customer (information user), (8) value in information use, and (9) provider network. The results obtained by the proposed method, the finite element method (wherever feasible), and Monte Carlo simulations for both benchmark and engineering applications verify the following: (a) the proposed methodology can achieve more accurate deterministic solutions with improved efficiency, thereby strengthening the effectiveness and efficiency brought by the stochastic method. Here is in the background of virtual prototyping modeling with Multiple feature cavities can be separated into their component feature parts. Morphological Map Analysis in Design Cashew Sheller (Kacip) as a Creative Process to Produce Design Concept Bertha Bintari Wahyujati Department of Mechatronics Product Design, Politeknik Mekatronika Sanata Dharma, Yogyakarta, Indonesia Corresponding Author: [email protected] (Received 29-05-2019; Revised 17-10-2019; Accepted 17-10-2019) Abstract The design of cashew nut … The control point, We examine the representation of geometric tolerances in solid-geometric models from the perspective of two classes of functional requirements. The user can explore the design space systematically using their experience to guide the outcome, or experimentally. To address this challenge, we propose a multilevel probabilistic morphological analysis. By incorporating multiple design dimensions and categories, new co-creation opportunities are highlighted and their requirements can be consolidated and optimized. That is, features originate in the knowledge or reasoning used in these activities. But to apparel designers, morphological analysis is still unused as before, because of the drawbacks of time and costs. The individual problem solver or a facilitated group brainstorms to define problem characteristics, also refered to as parameters. In the current research, the most commonly used product feature deconstruction methods are morphological analysis (MA) (Hsiao et al., 2010;Hsiao and Huang, 2002 Ko, 2013;Li and Zhu, 2017;Lin and Wei, 2017;Luo et al., 2012) and the numerical definition-based systematic approach (NDSA) (Chen and Chang, 2009). Michelle Dennis 4,216 views. This knowledge can enable process planning and other CAM operations to proceed automatically without human guidance or intervention.A method has been developed to automatically extract manufacturing information in the form of part features. This paper presents a CAD model simplification procedure that consists in recognizing and suppressing blend chains of certain types. be that others are not. The degree of automation is, however, very low in these industries. A morphological chart is a visual way to capture the necessary product functionality and explore alternative means and combinations of achieving that functionality. Model security for collaborative product design in a networked environment (or called networked manufacture, grid manufacture, and cloud manufacture) is an important and also challenging research issue. Afterwards those ideas can be mixed and matched to develop different solutions. The approach consists of performing a pair-wise comparison between components. The suppression stage ensures the geometric and topological validity of the simplification result. Selecting the stage for product design will then be important. Feature-based product modeling is the leading approach for the integrated representation of engineer- ing product data. An understanding of gender-based processing differences of product features is important to designers since it enables them to communicate with these different market segments and to produce effective products for each segment. The method is user-friendly because very little interaction is required to guide the software in its automatic creation of the desired analysis model. In CAE, the thin-walled models are often abstracted to a midsurface for quicker analysis. For analysis applications, the adaptation of the product geometry is required and consists of producing an idealised model out of a product solid one. To use a morphological matrix to generate concepts simply requires the user to select one solution from each column and then try to integrate the solutions into a complete concept.See the illustration below for details. Further fine-tuning on the sounds effect needs to be arranged to clear the findings. It is a visual aid used to come up with different ideas. The elements of CAM, however, cannot make full use of the CAD part description because it exists in terms of low-level faces, edges and vertices or primitive volumes usually unrelated to manufacturing processes. This methodology aims at exploiting the functional information of the assembly and interfaces between components to perform transformations of groups of components and assembly idealizations. A case study of business method patents concerning electronic shopping is presented to show the feasibility of the proposed approach. Strategies for identifying possible idealizations, controlling their application, and estimating the associated errors appear feasible. All firms that depend on technology for their competitive positions recognise that keeping abreast of technology-driven business model evolution is of vital importance. Ch. On the one side, this approach has stimulated the development of formal models and vocabularies, data standards and computational ontologies. A new feature recognition algorithm capable of recognizing interacting machining features and providing multiple interpretations is presented. Compound features can be recognized by combining maximal volumes. Computation of the midsurface has been observed to be effective when the original model is defeatured to its gross shape. Morphological analysis isn’t suitable for every product. DS 77: Proceedings of the DESIGN 2014 13th International Design Conference.
