.Amid the fierce rising competition in the market, accelerating the problem solving and decision making process have become major issues in product design especially in conceptual design stage. For years, Theory of Inventive Problem Solving (TRIZ) has been extensively applied in problem solving. In this paper, Analytical Hierarchy Process (AHP) was proposed to strengthen three major steps in TRIZ methodology namely as problem definition, root cause identification and solution generation. The integration was then structured in the form of computer-based system. The integration, application and software in AHP and TRIZ method have been discussed in this paper. This proposed support system not only provided evidence that TRIZ methodologies improved by the support of AHP and also aided the designers in early design phase such as concept, process and material selection.

Conceptual design is the most innovative stages in the life cycle of product development, and effect is the solving tools of TRIZ based on knowledge. The use of effects to solve the problem of conceptual design stage can improve the efficiency of Innovative design and competitiveness of enterprises. The problem-solving process of effects applied was described in this paper. In PROLOG environment, the knowledge representation was used to write the effect as expert knowledge base, and then the reasoning mechanism was used to make a simple expert system of effect. It also can be used to help designers check and resolve the design issues more conveniently.

Problem-solving therapy (PST) is a psychosocial intervention that teaches clients to cope with the stress of “here-and-now” problems in order to reduce negative health and mental health outcomes. In this chapter, the six stages of PST—problem orientation, problem definition, solution generation, decision-making, solution implementation, and outcome evaluation—are explained and exemplified via vignettes. Areas for which problem-solving therapy has been found useful are summarized, including depression, anxiety, relationship difficulties, and distress related to medical problems such as cancer and diabetes. The chapter describes contexts for practice, including primary care and home care, as well as adaptations for the use of PST with older adults. Finally, a case example of a problem-solving intervention with an unemployed depressed older man is presented to illustrate this approach.

Abstract Industry is currently evaluating hundreds of applications to innovate their products. The Theory of Inventive Problem Solving (TIPS) can help industry achieve this goal. It provides principles of standard thinking called inventive standards that are based on a limited number of physics phenomena and mathematics theories. Applying these principles of thinking would avoid generating undesirable solutions and approach desirable ones. The theory is very powerful and almost unlimited. The basic concept of TIPS is understanding the process of describing a product that would then leads to its development. It is best applied when there are strong conflicts that the designer has to resolve. For example, to design a tailor needle, we have to solve the eye conflict. The needle’s eye should be small enough to secure comfortable sewing and big enough to put the thread through. The objective of this paper is to discuss TIPS, describe its five levels of inventive tasks and develops a systematic procedure for its application. A case study is described that details the application from the conceptual design stage to the final inventive design stage.

As the description of design requirements at the earlier design stage is inaccurate and vague, it is difficult to figure out functional structure of a product and make sense product configuration. Therefore, it plays an important role to formally represent the process of design for product development in the conceptual design stage. Furthermore, port, as the location of intended interaction, is crucial to capture component concept and realize conceptual design for multi-solution generation. Agent is considered as an effective approach to collaboratively implementing design problem solving and reasoning. Combining both port and agent may be employed to generate new concepts of the product in order to customize product scheme varieties. In this paper, the product module attributes are firstly described. The objective is to implement modeling of design process for obtaining system new concepts to guide multi-solution generation. Secondly, an effective approach to decomposing design process is presented to describe the process of structure generations and product decomposition by formal representation. According to properties of modularity for product development and component connections, we can calculate the number of component connections and density of components. In addition, product module division and coupling degree analysis are conducted, and coupling degrees are calculated by considering the correspondence ratio and the cluster independence. A port-based knowledge building process is described for functional modeling. A port-agent collaborative design framework is given and describes different agent functions to help designers to obtain new design schemes. Finally, a case study is presented to describe the modeling process of conceptual design.

The article discussed the issues of creating a decision support system in the design process. It is based on morphological methods and approaches. These approaches can be successfully used to accelerate the evaluation, synthesis and selection of engineering solutions at the conceptual design stage. With the help of combinatorics, it is possible to generate a significant number of different engineering solutions. The conceptual stage is the most important in determining the future parameters and characteristics of the designed systems. The article also considers the possibility of computerization of the morphological approach. All this leads to an increase in the efficiency of the design process as a whole.
