The quality and operations representa-. For the manufacturing workforce, however, these remain limited to informal ‘On-the-Job’ approaches, administered by peer colleagues – particularly in Small and Medium Enterprises (SMEs) where economic, educational, cognitive and cultural constraints are often deeply embedded. With the help of KFADs and the machine elements taxonomy to enable consideration of movements, diverse considerations and design solutions are possible. Customer needs analysis, product benchmarking, and business case analysis are fundamental to specification development, whereas conceptual design and product refinement entail functional analysis, the generation of solution principles and product geometry, concept selection, mathematical modeling, prototyping, and Taguchi analysis for variability…, A Customer Needs Motivated Conceptual Design Methodology for Product Portfolios, A customer needs motivated conceptual design methodology for product portfolio planning, A functional basis for engineering design: Reconciling and evolving previous efforts, EVOLVING A FUNCTIONAL BASIS FOR ENGINEERING DESIGN, Using quantitative functional models to develop product architectures, A heuristic method for identifying modules for product architectures, improving product performance by integration use taks during the design phase : a behavioural design approach, The function analysis diagram: Intended benefits and coexistence with other functional models, QFD-based modular product design with linear integer programming—a case study, A systematic method for developing function structures, solutions and concept variants, A Comparative Analysis of the Theory of Inventive Problem-Solving and the Systematic Approach of Pahl and Beitz, Representation of Design Object Based on the Functional Evolution Process Model, Classifying Functions for Mechanical Design, Quality Function Deployment : Integrating Customer Requirements into Product Design, The Failure-Experience Matrix—A Useful Design Tool, A Reverse Engineering and Redesign Methodology for Product Evolution, View 3 excerpts, references methods and background, Proceedings of the ASME Design Theory and Methodology Conference, By clicking accept or continuing to use the site, you agree to the terms outlined in our. Although this practice reduces risks — being, as it is, based on already tested platforms, incremental innovation often leads to the retention of superfluous components and outdated technologies. The results have shown that the FMEA-FAD method has significantly improved the efficiency and the effectiveness of the process. FAD models of the system. The hypothesis of. The next step in the reverse engineering process involves the study of the object’s function. [4] (NOTE: In these examples, other key aspects - such as concept evaluation and prototyping - are subsets and/or extensions of one or more of the listed steps. 2nd ed. It is paramount for the design to be checked for its manufacturability with the available manufacturing resources, tooling operations and quality critical machining carried out with minimum number of setting. At a basic level, product design composes three primary tasks: specification development, conceptual and configuration design, and product refinement. The connector has snaps that securely attach the body parts together, but the snaps also allow easy disassembly when enough force is applied. Functional Analysis... 2 engineering specifications to be determined early in the design process, directly after the ... crucial phases in the “reverse engineering” design process. In fact, this step is often termed Ideation or "Concept Generation." » In VE, the “significant few” are identified based on the Value Index (VI) » VI=Price/Worth, the larger the VI value the better the chance for improvement » Worth: Least expensive method of performing the basic function. Diego, CA, 15–21 November 2013. A review of current helicopters was conducted to determine the technology in the drive-train systems. FAD-assisted FMEA-VE process: FAD models assist on the first phase of the FMEA process by ''filtering'' the input to the tabular tool. It’s fun and also educational. Breaking the system down into lower level subsystems and studying the functional interrelationships between system components, can help us understand the overall system functions (Pahl et al., 1996). This step identified the pisto, forming more than satisfactorily has initi, floating piston sub-assembly was identifi, ment process ran smoothly and efficiently wit, FMEA analysis of the piston part (Figure 4), a member, of the design team identified a superfluous machin, ations (tool change and drilling) resulting in an approx-, As dictated by Step 5 of the process, a separate, sheet of the FMEA spreadsheet was used for each of, the two sub-assemblies and the parts were grouped, based on the function they perform (see Table 1). ): Handbuch Produktentwicklung. This methodology was based on FMEA-FAD, a methodology developed to improve the resour, ciency and effectiveness of the first phase of the FMEA, 2014 and is the standard FMEA practice in the com-, The primary aim of this work was to develop a FAD-, in a single process and evaluate its resource efficiency in, cesses to identify and address any potent, modes (ways in which the product or process may, which ways can a system or component fail to, deliver).
