Starting Point

The importance of the concept development phase in product development is contradictory to the level and amount of current computer-based support for it, especially with regards to mechanical design. Paper-based methods for conceptual design offer a far greater level of maturity and familiarity than current computational methods. Engineers usually work with software designed to address only a single stage of the concept design phase, such as requirements management tools. Integration with software covering other stages, e.g. functional modeling, is generally poor. Using the requirements for concept models outlined in the VDI 2221 guideline for systematic product development as a starting point, the authors propose an integrated product model constructed using the Systems Modeling Language (SysML) that moves beyond geometry to integrate all necessary aspects for conceptual design. These include requirements, functions and function structures, working principles and their structures as well as physical effects. In order to explore the applicability of SysML for mechanical design, a case study on the design of a passenger car’s luggage compartment cover is presented. The case study shows that many different SysML diagram types are suitable for formal modeling in mechanical concept design, though they were originally defined for software and control system development. It is then proposed that the creation and use of libraries defining generic as well as more complicated templates raises efficiency in modeling. The use of diagrams and their semantics for conceptual modeling make SysML a strong candidate for integrated product modeling of mechanical as well as mechatronic systems.

Mechanism and function formalization problem is touched in a novel task based conceptual mechanical design method. The general concept and a specific application of this method were reported in earlier publications. Direct dependence between the function and mechanism, identical synthesis tools for various stages of design and for various mechanical objects are the features making the suggested method advantageously different from existing concept design approaches. The core idea of suggested conceptual design method is the direct relation between challenged function and the mechanical entity which is in charge of implementing the requested function. The existing task based conceptual design methods are not satisfying the designer’s needs for scope of application, universality of design means, visualization and formalization of both mechanical and functional fields. Formalization of functions and mechanisms is an important design tool that will facilitate synthesis, analyzes, visualization and archiving (data base creating) processes of mechanical development. Further progress in unveiling the resources of the suggested design method is mostly based on development of formalization means for both categories of functions and mechanisms. The current study is unveiling newly developed function and mechanism description language that is helping to formalize both mechanical and functional categories facilitating their involvement in design process and making the description of a new product’s mechanical development easy and understandable. Function formalization in conjunction with mechanism formalization allows to formulate precisely the design task and concentrate the designer’s attention on solution of a single task strictly arranged in the hierarchical function tree of all involved tasks and functions.

Design Cycle

A novel approach of task based conceptual design(TBCD) has been successfully used as direct guider and efficient developer of unique mechanical structures for many cases of mechanical design. Nearly a decade long efforts of elaboration of efficient every day usage formats for this method have been ended in convenient design pages suitable and applicable for revealing, describing, visualizing and managing the data necessary for organizing the design process from task definition to solutions satisfying original design tasks. The aim of current study is to show steps of a solution generation within frames of a single design cycle and extend this action over consecutive design cycles. Those steps are described from standpoint of general concept design method starting from key model and finished with final aggregation matrice as ultimate step of a single design cycle. Unified mathematical expressions are used for introduction and description of all worked out and developed components of conceptual design. The paper is arranged in a way to show gradual steps of conceptual design(CD) of a power transmission system – a pipe wrench life test machine.

And Control

Mechatronic systems are a combination of cooperative mechanical, electronics and control components. The high number of their components, their multi-physical aspect, the couplings between the different domains involved and the interacting design objectives makes the design task very tedious ad complex. Due to this inherent complexity, a concurrent systematic and multi-objective design thinking methodology is crucial to replace the often used sequential design approach that tends to deal with the different domains separately. In this research we present a new multi-criteria profile for mechatronic system performance evaluation in conceptual design stage. The newly introduced Mechatronic Multi-criteria Profile (MMP) includes various quantitative members such as intelligence, reliability, complexity, flexibility and cost. A nonlinear fuzzy integral called 2-additive Choquet Integral will be used for the aggregation of criteria and fitting the intuitive requirements for decision-making in the presence of interacting criteria. Finally, the effectiveness of the proposed method will be validated via a case study of designing a robotic visual servoing system.

The Impact

Conceptual design for complex products like aircraft and power plants requires a considerable effort since the product models become very large if they are to cover all important aspects for different stakeholders. To cope with this overall effort, designers have to rely on legacy designs and reuse, and improve the product concepts incrementally between product generations. This paper describes a generalized inheritance mechanism we call generic object inheritance that enables quick reuse and modification of conceptual product models at any level in their hierarchical break down structures. By facilitating reuse of conceptual models of previously well studied products, more time can be spent on developing the parts that contain the edge of a new product generation. This enables keeping the modified concepts in context of a complete analyzable product model where the impact of changes can be studied without having to maintain multiple copies of the same object structures. The paper describes how generic object inheritance is used for developing the next version of a conceptual product model of a small business jet, while reusing the essential parts of the previous version with minor modifications to design parameters and substructures. The design and core mechanisms of generic object inheritance are briefly described, and illustrated with examples from the case study.

Types Of Information

A study on utilising a graphical interface to represent movement transmission within products has been conducted to support a creative conceptual design process that separates the consideration of functional requirements and motion requirements. In engineering design, many representations of product structure have been proposed to assist in understanding how a design is constituted. However, most of these representations demonstrate only functions and are not able to demonstrate design structure. Functional Analysis Diagrams (FAD) provides a solution for this. An FAD shows not only functions but also physical elements by the network of blocks and arrows and thus it is capable of demonstrating various types of information and the design scheme. This characteristic gives FADs an advantage for designers to combine different types of information including useful and harmful interactions to gain an overview of the design task. This study focuses on using circles instead of arrows to represent movement attributes of mechanisms and machine elements in a Kinematic Functional Analysis Diagram (KFAD) and explores methods of utilising it in mechanical design. A commercial case study of medical equipment design conducted with the assistance of KFADs and a component database, mechanism and machine elements taxonomy (MMET), is described to illustrate the process. The design outcome shows that it is feasible to follow the proposed conceptual design process. With the help of KFADs and the machine elements taxonomy to enable consideration of movements, diverse considerations and design solutions are possible.

Multiple Domains

Development of mechatronic products is traditionally carried out by several design experts from different design domains. Performing development of mechatronic products is thus greatly challenging. In order to tackle this, the critical challenges in mechatronics have to be well understood and well supported through applicable methods and tools. This paper aims at identifying the major challenges, by conducting a systematic and thorough survey of the most relevant research work in mechatronic design. Solutions proposed in literature are assessed and illustrated through a case study in order to investigate if the challenges can be handled appropriately by the methods, tools, and mindsets suggested by the mechatronic community. Using a real-world mechatronics case, the paper identifies the areas where further research is required, by showing a clear connection between the actual problems faced during the design task and the nature of the solutions currently available. From the results obtained from this research, one can conclude that although various attempts have been developed to support conceptual design of mechatronics, these attempts are still not sufficient to help in assessing the consequences of selecting between alternative conceptual solutions across multiple domains. We believe that a common language is essential in developing mechatronics, and should be evaluated based on: its capability to represent the desired views effectively, its potential to be understood by engineers from the various domains, and its effect on the efficiency of the development process.

Recent studies [1, 2] were devoted to author's efforts in formalization of conceptual design process based on vast data in mechanical design accumulated over years. The suggested novel method of conceptual design is implying direct dependence of function and a mechanism intending to implement the challenged function, considering a wider interpretation for both categories of mechanism and function. Main aspects of this method relate to formalization of both mechanism and function, formatting of design pages for tracking the concept design process, formalization of synthesis and analyze tools and formation of design models serving different design targets. Effectiveness of those formalization tasks is based on development and usage of specific graph and matrix based mathematical engine, enabling compact presentation of various aspects of conceptual design method. The current study is aiming to disclose the specific conditions of formalization for reconfigurable as categories widely used in mechanism synthesis and analyzes. Formalization of reconfigurable mechanisms will categories is contribute a lot in effectiveness of organization of concept design. An example from design experience is considered to confirm the validity of suggested formalization approach for the case of reconfigurable mechanisms.

The research approach presented in the paper targets the integration of some advanced engineering principles, methods and instruments for enhancing the effectiveness and efficiency of Product Design activities. In order to reduce the product development resources consumption, to improve the product functionality, reliability and flexibility and to reduce the product lifecycle environmental impact, all of these being considered as instruments for improving Product Sustainability, some conceptual models for integrating advanced Product Design theories and principles such as Holistic Design and Axiomatic Design, together with the use of some advanced CAD/CAE tools are discussed in the paper. As case study, the paper submits to discussion the problem of enhancing the design activities for the development of a technical solution of a device adaptable on an electrical discharge machine-tool and being able to generate cycloid profiles based on a double-planetary mechanism driving. The research approach on integrating the principles of axiomatic design within activities of the design model structuring, the decomposition rules have been mainly targeted to be applied. The presented case study refers also to the performance of using advanced capabilities of Solid Edge as CAD solution which provides dynamic generation of the product model structure and to those of its embedded module entitled Engineering Reference, as valuable CAE instrument. Some adequate conclusions are finally presented and some directions of further research development are identified, such as integrating also an economic efficiency analysis and a Life Cycle Impact Assessment approach as Concurrent Engineering activities, to enhance the new product development sustainability.

Engineering Strategy

One of the keys to success for product competition in the market depends on the effectiveness of its product development. This article presents a generic framework of product development which focuses on the conceptual design. The framework is developed with concurrent engineering strategy where it takes into account the product life cycle considerations within the early phases of the conceptual design. The proposed framework starts from product investigation, product specification and conceptual design. Implementation of the framework is illustrated on a case study of metal matrix composite brake disc rotor design, where there is an avenue for conceptual research since the progress of metal matrix composite utilisation in the automotive industry is limited due to their high cost in comparison with conventional alloy. The possible outcome for product investigation, product specification and conceptual design of metal matrix composite brake disc rotor are presented as part of the selection of best conceptual design. Moreover, the proposed framework is an aid to help engineers and designers to make an effective and systematic product development through a sound conceptual design decision from possible product concept alternatives.
