“…It is important to remember that innovation implies the commercial success of the product, the design by itself does not guarantee it. However, it is a fact that the inventive elements incorporated into the concept of design are fundamental on the road to innovation [36]. Although the application of TRIZ does not demand a deep knowledge of the disciplinary field where a new technology is being developed [37], for this particular case, part of the success in the result obtained was due to the experience and knowledge of the designers in the field where the development of the device is being developed.…”

Innovations within the medical device sector are constantly and rapidly emerging due to increasing demand, especially for orthosis systems, which usually constitute built rigids with low comfort, due mainly to the standardized production process. This article reports the design process of a plantar orthosis system from the application of Theory of Inventive Problem Solving (TRIZ) tools, known as generic parameters, matrix of contradictions, and inventive principles. The final orthosis is integrated by four modules or components (1 central and 3 movables) and customers can buy only the required ones, reducing cost in unnecessary parts. The plantar orthosis was defined based on three engineering parameters that delimited the design work by developing a customizable system that is capable of performing simultaneous functions and whose manufacture could be standardized. We identified the existence of a technical contradiction between the engineering parameters, customization, and standardization, which was solved by the inventive principles of segmentation, inversion, transition to a new dimension, and porous materials. A modular design with four components was accomplished, molds are built for each component in a machining center and injected using granulated ethylene vinyl acetate copolymer. The positions of the movable components are configured through a bolt-hole assembly mechanism to the central component, which is a flat perforated plantar base. The novelty in the design here presented is elated to supports that constitute the orthosis, which are interchangeable and adjustable to the pathological and morphological needs of each patient.

“…the central column of the matrix represents the Present, the left column represents the Past and the right column represents the future. Therefore, even if the tool was originally developed for performing problem analysis, the SO can be used also for performing structured brainstorming processes (Frillici et al, 2015). Considering the SO shown in Figure 2, the cell number five can be interpreted as it follows: "what can be done to the system when the problem appears?".…”

Design methods are claimed to support designers but, although they are largely taught in academia, their industrial uptake is still lacking. Many reasons have been identified about this flaw and some potential suggestions have been proposed and discussed in literature to overcome the problem. However, a further evidence is that although many students learn such methods from years, they partially or totally abandon the learned methods in their professional careers. This could partially explain the gap between academic and industrial diffusion of design methods. Literature provides suggestions for improving the learning experience of students but different didactical contexts may need more tailored solutions. The work shown in this paper exploits the problem solving potentialities of the TRIZ toolset to provide hints for improving a course focused on teaching a systematic conceptual design method. A set of suggestions has been obtained together some guidelines for applying the considered TRIZ tools to other didactical contexts.

“…For instance, Samuel and Ohler (2014) suggest a classification framework of TRIZ techniques based on their potential role with respect to various engineering design activities. In Frillici, Fiorineschi, and Cascini (2015) and Fiorineschi, Frillici, and Rotini (2018a), TRIZ tools are discussed with reference to their relationship with the main conceptual design phases and the functional decomposition tasks. In other works from the same authors (Fiorineschi, Frillici, & Rotini 2018b;Fiorineschi et al 2018c), a specific set of TRIZ tools is integrated in a systematic conceptual design process based on problems and solutions co-evolution.…”

Although TRIZ is widely acknowledged as a powerful aid to improve efficacy and efficiency of the creative design process, practitioners diffusedly experience difficulties in the selection of the most suitable tool. Such an issue represents a severe limitation in consideration of the large number of tools TRIZ offers. Here, Inventive Principles (IPs) are acknowledged as the most popular TRIZ technique, and their conjointly use with the Contradiction Matrix makes the selection of the appropriate IP a sufficiently supported task. However, the reliability of the Contradiction Matrix is often questioned and an agreement on a solid and reliable procedure for the selection of IPs is far from being reached. In such a context, the paper investigates the recurrence of IPs to solve contradictions, with reference to a classification framework that takes into consideration the nature of the problem to be solved and the technical-scientific domain it belongs to. The outcomes of the analysis reveal that leveraged IPs are considerably related with the technical-scientific domain and the nature of the problem to be solved. The found relationships are worth delving into and translating into selection guidelines.
