Conceptual Design Phase

Faster product lifecycles make long-term investments in machines for micro assembly riskier. Therefore, reconfigurable manufacturing systems gain more and more attention. But most companies are uncertain if a reconfigurable manufacturing system can fulfill their needs and justify the initial investment. New and improved techniques for product development have the potential to foster the utilization and decrease the investment risk for such systems. In this paper, four different methods for product development are reviewed. A set of criteria regarding micro assembly on reconfigurable manufacturing systems RMS is established. Based on those criteria and the assessment, a novel approach for a product development method is provided, which tries to combine the strengths of the beforehand presented approaches. It focuses on the conceptual design phase to overcome the customers’ uncertainty in the development process. For this, an abstract representation of a micro-assembly product idea as well as a decision tree for joining processes are established and validated by real product ideas using expert interviews. The validation shows that the conceptual design phase can be used as a useful tool in the product development process in the field of micro assembly.

Variable Transmission

Previous research and publications at Brigham Young University have established the new positive engagement continuously variable transmission (PECVT) family of continuously variable transmissions (CVTs). Various embodiments of PECVTs have been identified and surveyed; resulting in the identification of the behavior termed the non-integer tooth problem. Additional research has been conducted to further explore the non-integer tooth problem and identify a feasible solution to the problem through the use of a product development method. This publication will address the conceptual design phase of the product development process for a PECVT. This will include: the identification of the operating conditions of a PECVT, i.e. further detail of the non-integer tooth problem, identification of required characteristics for a solution, design specifications, concept generation, concept evaluation, and concept selection. The conceptual design phase will result in a conceptual solution which will satisfy the identified characteristic requirement and designs specifications.

Reconfigurable manufacturing systems (RMS) can be used to produce micro-assembled products that are too complex for assembly on flat substrates like printed circuit boards. The greatest advantage of RMS is their capability to reuse machine parts for different products, which enhances the economical efficiency of quickly changing or highly individualized products. However, often, process engineers struggle to achieve the full potential of RMS due to product designs not being suited for their given system. Guaranteeing a better fit cannot be done by static guidelines because the higher degree of freedom would make them too complex. Therefore, a new method for generating dynamic guidelines is proposed. The method consists of a model, with which designers can create a simplified assembly sequence of their product idea, and another model, with which process engineers can describe the RMS and the procedures and operations that it can offer. By combining both, a list of possible machine configurations for an RMS can be generated as an automated response for a modeled assembly sequence. With the planning tool for micro-assembly, an implementation of this method as a modern web application is shown, which uses a real existent RMS for micro-assembly.

Holistic Description

The conceivable evolution of information technology will enable mechatronic systems with inherent partial intelligence. We call this kind of systems self-optimizing. Self-optimizing systems are able to react autonomously and flexible to changing environmental conditions. They are capable of learning and optimizing their behavior at run-time. This paper presents the paradigm of self-optimization and shows how to develop self-optimizing systems. Focus is the conceptual design phase. The result of this phase is the principle solution. In this paper at first we explain how to describe the principle solution in a domain-spanning way. This is of high importance because a holistic description of the principle solution constitutes the basis for the communication and cooperation between the engineers from different domains who are engaged in developing a self-optimizing system. At second we introduce solution patterns for developing principle solutions. Solution patterns enable the reuse of design knowledge so that the development process will be more effective. This paper focuses on solution patterns including self-optimizing solutions. How the methods work we explain by the complex magnetic linear drive of a shuttle.

Hierarchy Process

Pemilihan konsep reka bentuk yang sesuai di peringkat reka bentuk gagasan dalam proses pembangunan produk adalah merupakan keputusan yang genting. Keputusan yang tidak tepat boleh menyebabkan sesuatu produk itu perlu direka bentuk semula atau dikilang semula. Salah satu daripada keadah yang boleh digunakan dalam menentukan konsep reka bentuk yang paling sesuai adalah process hierarki beranalitis (AHP). AHP telah digunakan dalam hampir kesemua aplikasi yang berkaitan dengan membuat sesuatu keputusan. Dalam kertas kerja ini, hasil daripada kajian kes menunjukkan bahawa konsep AHP boleh membantu pereka bentuk untuk membuat penilaian secara berkesan daripada pelbagai konsep reka bentuk di peringkat reka bentuk gagasan. Kertas kerja ini memaparkan kaedah pemilihan konsep reka bentuk dengan menggunakan proses hierarki beranalitis. Kata kunci: Process hierarki beranalitis; reka bentuk gagasan; proses pembangunan produk; perbandingan pasangan; pembangunan kerusi roda Selecting the right design concept at conceptual design stage in product development process is a crucial decision. Inaccurate decision can cause the product to be redesigned or remanufactured. One of the useful tools that can be employed in determining the most appropriate design concept is Analytical Hierarchy Process (AHP). AHP has been employed in almost all applications related to decision–making problems. In this paper, the results of a case study illustrates that AHP concept can assist designers to effectively evaluate various conceptual design alternatives at the conceptual design stage. This paper presents the methodology of selecting design concepts using analytical hierarchy process.

Changing Role

In recent years, the benefits of using FEA or design analysis as part of conceptual design have become apparent. The direct involvement of design engineers in analyzing their own designs allows for quick turnaround times and ensures that design modifications indicated by analysis results are promptly implemented in the design progress. Used properly, it yields trustworthy results that are already driving efficiencies and cost savings in industries ranging from consumer goods to automotive. This paper will outline the advances in technology which have made this change possible.
