Function based design methods — those that are largely a derivative of Pahl and Beitz’s systematic approach — are a powerful tool employed in a variety of engineering design contexts. However, many other design methodologies exist and are useful in solving design problems. These methods include varying approaches from Suh’s Axiomatic Design to Altshuller’s Theory of Inventive Problem Solving (TIPS or TRIZ) to the business-motivated Ulwick’s Outcome Driven Method. In this paper an attempt to merge the philosophy of functional design with the problem solving approach of TRIZ is undertaken. A framework is proposed combining functional modeling formalized by the Functional Basis with TRIZ. The process of merging the two methodologies is presented along with the key contribution, a matrix that relates the vocabulary of the Functional Basis with the 40 inventive principles of TRIZ. The use of the Functional Basis-TRIZ (FB-TRIZ) hybrid design methodology is described and a case study is presented demonstrating its use as well as the creative solutions that the approach affords.

Early Phases

Abstract The design for additive manufacturing (DFAM) processing was introduced to fully utilise the design freedom provided by additive manufacturing (AM). Consequently, appropriate design methodologies have become essential for this technology. Recently, many studies have identified the importance of DFAM method utilisation to produce AM parts, and TRIZ is a strategy used to formalise design methodologies. TRIZ is a problem-solving tool developed to assist designers to find innovative and creative solutions. However, the pathway for synergising TRIZ and DFAM is not clearly explained with respect to AM capabilities and complexities. This is mainly because most methods continue to involve use of the classical TRIZ principle, which was developed early in 1946, 40 years before AM technologies were introduced in the mid-1980s. Therefore, to tackle this issue, this study aims to enhance the 40 principles of classical TRIZ to accommodate AM design principles. A modified TRIZ-AM principle has been developed to define the pathway to AM solutions. TRIZ-AM cards are tools that assist designers to select inventive principles (IPs) in the early phases of product design and development. The case study illustrates that even inexperienced AM users can creatively design innovative AM parts.

Tools And Methods

Bioinspired design is becoming an increasingly popular approach that makes use of nature as a source of inspiration to develop designs. Tools and methods are currently being evaluated to determine how designers may best leverage biological systems to generate designs. In this paper we present a study in an engineering elective course at Texas A&M University that explores the effects of five different methods for bioinspired design on the quality and quantity of ideas generated, student self-efficacy, as well as student feedback. These methods include Directed, Case Study, the use of AskNature.org, BioTRIZ, and Functional Modeling. We show that each of the methods produces numerous effective and creative solutions, with a high quality and quantity of ideas. We also show that the methods utilized to teach bioinspired design methods positively affect the students’ design confidence, outcome expectancy and anxiety, while also preserving students’ high motivation towards engineering design. Finally, we identify potential areas for improvement for the methods and the course.

Hybrid optimization, a new approach to design optimization employing both symbolic reasoning and algorithmic analysis, has been applied to the design of kinematic pairs in mechanisms. This hybrid design methodology provides a three-step systematic approach for (1) combining the degrees-of-freedom found in simple, lower kinematic pairs to obtain more complex but robust higher pairs, (2) judging inappropriately assigned joints for the elimination of redundant kinematic constraints and harmful mobilities, and (3) assisting nonexpert designers in applying nonlinear programming algorithms for detailed numerical design optimization of kinematic pairs. An example taken from the design of a spatial mechanism, specifically a universal joint, is presented and serves to demonstrate the utility of this procedure for detailed hybrid design optimization of kinematic pairs in mechanisms.

Bionic designs which have evolved from time-tested strategies of nature have beena source of inspiration for designers to solve problems. The beauty of nature’s formis derived from effective evolution and robustness of its function. Current bionicdesign methods are analogical and hence are discordant to the design engineeringworkflow. In this paper, a methodology is proposed which suggests suitable bionicstructures to a given design space. The methodology consists of the following stageswhich are Bionic representation, Relation, Emulation, Engineering specifications,Design verification and optimisation (BREED) and finally realization. Thismethodology aims to function as a systematic problem-solving approach to retrievestructural inspirations from nature and mimic its form. The methodology alsointegrates biological inputs to the context of an engineering design problem.Inspiration and validation phases of the bionic structure are represented as a V-model. The designer can leverage this framework to come up with novel bionicdesign concepts. A structural dome is used as a case study to demonstrate theprocedure of BREED methodology. Biological forms for the dome are obtainedusing a spectral matching technique. The bionic design is validated after applyingrelevant boundary conditions and by using proven engineering methods.

Product Service Systems

The diversity of costumer’s needs requires manufacturers to provide a complex package of product and service. In contrast to traditional matured methods used for product design, Product/Service Systems (PSS) design still has a large room for development because of three following core research challenges: 1) development of a common shared structure to represent and understand PSS’s elements and their relations; 2) systematic modelling approaches to formulating design problems; and 3) holistic consideration of social, technological, economic and ecological elements. This paper aims to propose a novel framework for PSS design by addressing three issues above. The proposed framework is derived step-by-step from a natural language description of PSS environment using Environment-Based Design (EBD) methodology. The proposed framework attempts to accommodate the recursive scenarios in PSS design along with PSS lifecycle. The PSS environment will be firstly analyzed through a question-asking strategy. Besides, a set of graphical tools will be presented to support the development of framework, such as product-environment system, performance network, and conflict map. A case study, concerning the service design of intellectual property protection in collaborative product development, will be presented to illustrate the proposed framework.

Purpose Planning for the future can become mired in fixing the problems of the present. To create alternative solutions, planning must break free of the boundaries and assumptions of existing paradigms. The purpose of this paper is to explore an alternative way of thinking that reframes the issues from problems of “what is” to the potential of “what could be” in the context of socio-ecological resilience. Design/methodology/approach A case study reviews the limitations revealed during a traditional problem-solving exercise on the topic of Coastal Eco-Cities, as well as the innovations resulting from the rethinking of the issues through the lens of the alternative paradigm. Findings A key finding is the significance of linguistic modality, shifting from objective expressions to subjective dialogue. Originality/value The originality of this approach is the emphasis on the framing of the problem before the development of the solution and the methodological implications of this early dialogue.

Functional Flexibility

Extending product life is one of the hopeful approaches to reduce the environmental issue, which is one of the most critical issues of today. However, many products are thrown away because of obsolescence of functions and their performance. Therefore, we should design products to be functionally upgradable. Moreover, such upgradable products may create business chances at later stages of product life cycles. The objective of this research is to propose a design methodology for upgradability. This methodology employs a functional modeling scheme, FBS modeling, because upgrade design is a distinctive application of functional design that aims at maximizing functional flexibility with minimal structural changes after the product is manufactured. Here, the functional flexibility refers to an ability of a product to adapt its functions to changes of user needs. This paper proposes and models design processes and design operations in the upgrade design. Especially, the methodology supports finding out candidates of modifications of the function structure and configuration of a platform, which is common structure of a product among several generations, and upgrade modules. One of its central issues of upgrade design is treatment of future uncertainty. For this purpose, we propose two design strategies: delayed selection of components, and expanding and shrinking platform. A prototype system and a case study of upgrade design for a vacuum cleaner are also illustrated. The case study indicates that the system succeeded in systematically supporting a designer to execute the design methodology. Regarding the functional design, as an extension of FBS modeling, this paper proposes a method to relate abstract entity concepts in FBS modeling to concrete components through a quantitative behavior model and range calculation, in addition to deployment of FBS modeling for the design methodology.
