For every design phase, various support tools and resolution methods are proposed in the literature. These tools are however very difficult to implement in an SME, which may often lack resources. In this article we propose a complete design process for new manufacturing techniques, based on creativity and knowledge re-use in searching for technical solutions. Conscious of the difficulties of appropriation in SME, for every phase of our design process we propose resolution tools which are adapted to the context of a small firm. Design knowledge has been capitalized in a knowledge base. The knowledge structuring we propose is based on functional logic and the design process too is based on the functional decomposition of the system, and integrates the simplification of the system architecture, from the early phases of the process. For this purpose, aggregation phases and embodiment are proposed and guided by heuristics.

These atmospheric conditions appear to be highly variable according to the flight phases of the aircraft. The difficulty when designing air-conditioning systems for civil aircrafts is also inherent to the complexity of the coupling of the nonlinear physical phenomena inside of these systems (multi-physics, multi-scaling). Therefore, the design space appears to be very broad and quite difficult to explore. Embodiment design choices are relating to continuous and discrete design variables while the system effectiveness is extremely sensitive to most of these design variables. There is a lack of tools to support the investigation of the design exploration space and designer decisions at early stages of the design process. In this paper, a method is proposed to generate feasible embodiments and manage the compromise between various design requirements. A digital tool based on the meta-heuristic of Genetic Algorithms (Gas) has been developed to investigate the design problem. The selection of non-dominated solutions (Pareto) is used to identify relevant values for design variables and to facilitate choices among the design solutions of the air conditioning system.

Several approaches deal with the extraction of pertinent information from patents, some of them translate that information into useful knowledge for problem-solving purposes. However, very few methods use a physical approach and a consistent analysis of the main function in the problem definition phase. This paper proposes a new method to inspire designers with ideas and analogous solutions. The objective is to contribute to solve complex technical problems by exploiting knowledge found in patent documents. The method is divided into three sections: problem definition, research and analysis, and innovation. The first two sections use iteratively a knowledge base formed by pertinent keywords related to the problem context, physical keywords from functional decomposition and physical analysis, and technological keywords recovered through patent analysis. In the third section, interesting patents are classified in a structured discovery matrix from the physical phenomena involved which are crossed in accordance with the related techniques found. The method is supported by a physical effects database of energy conversion and by evolution trends of technical systems. A deep offshore biphasic separator illustrates the method.

Several authors exploit patents using the evolution laws of the TRIZ theory to anticipate technological leaps, categorize patents in a TRIZ perspective, forecast technology, etc. TRIZ laws can be completed with Polovinkin’s rules, design rules, better known as “design heuristics,” and the rules of the art of engineering (engineering best practices). In this chapter, we propose evolution trends composed of all these elements and presented in the form of cards to assist users. After selecting pertinent patents, they can be classified into discovery matrices and analyzed in a timeline classification structured according to their technological branches. The evolution trends enable us to decipher the evolution in inventions being followed or to be followed by each technological branch. An in-depth analysis of several technological branches linked to the technical problem in question allows us to inspire users with original ideas, identify opportunities for innovation, and propose hybrid solutions. To illustrate our approach, we look for possible evolutions of current, deep offshore biphasic separation systems.

The processes of quality assurance impose the qualification of the production devices. A procedure and a test part are proposed for that purpose; intended for the family of processes of point-by-point layer manufacturing. Existing test parts only permit benchmarking and comparisons between machines: their capacity can be evaluated, but the test part analysis does not make it possible to establish the link between noted defects and their causes. The proposed process and test part permit the identification of the defects and whether their origins are machine or material linked. This paper describes the approach used to design the test part. Some preliminary measures were made on a test part, in order to discuss procedure and measurements.

Nevertheless, many students have difficulty grasping mechanical systems, from a 2D design plan or a 3D CAD definition. This is why we implement real system manipulations, associated with various representations, especially for students with no technological skills. Augmented reality can provide an answer to the difficulty of making the link between a representation and the real system. Since augmented reality has not yet been used in mechanical design pedagogy, the challenge was to evaluate the relevance of this technology to facilitate understanding of mechanisms. An augmented reality scenario has been implemented on an electromechanical mechanism. It makes it possible to identify components and their locations, to explore the mechanism and thus more easily identify the kinematic chain or transmission power flow for example. Two different interfaces were used by the learners (tablet and HoloLens glasses), each of which has its advantages. The first experiment was conducted with students in engineering training, as well as bachelor of technology students. During analysis of mechanism practical session, half of the workforce used augmented reality, while the others had only paper documentation and cad. At the end of the session, an assessment of the system’s understanding was conducted ‘hot’ and shows improvements for augmented reality users. Here, augmented reality is used in pedagogy, as a new medium support to pedagogy. But this experience is also relevant for introducing engineering students to a relevant technology for industry of the future, enabling them to measure the potential of augmented reality.

It is difficult to take into account simultaneously every requirement imposed by the different phases of the product life-cycle. In this paper, a method is proposed to perform the analysis of the embodiment design problem. It facilitates the search of the indispensable elements, suitable for structuring the preliminary design phase. Our approach is performed for the relevant life-cycle situations of the product. A four level analysis (need, functions, organic structure and physical behaviours) is proposed. The set of structuring elements allow the design problem definition as a Constraint Satisfaction Problem (CSP).

A design methodology is proposed, based on design knowledge reuse and suitable for developing new manufacturing processes in an SME context. This paper describes a knowledge structuring and capitalization method, where a functional description is applied. The purpose is to capitalize technical solutions and the components used to carry out a given function, and to build a knowledge base that could be reused when designing new manufacturing processes. In this way, the time spent on research into design concepts can be reduced. Components are identified using the Converter-Transmitter-Operator-Control classification, based on describing the functional flow path in terms of energy. Produced and induced effects associated with the components are highlighted, by identifying the relevant conjugate variables for the functional flows. The choice of solutions in the reuse phase is thus facilitated by considering these effects. In addition, a task decomposition tool has been developed to simplify the describing of existing manufacturing processes. Existing knowledge capitalization methods proved unsuitable for an SME context. Based on the proposed approach, we applied our capitalization method in an industrial context, with the processes used by our partner company, which had never previously capitalized its design knowledge.

In this context of preliminary design stages, several approaches exist, which correspond to slightly different complexities and issues and must consequently be used at different moments. We consider in this paper three families of approaches: 1) exploring design (parametric) dimensioning under uncertainty (through constraint programming techniques, representations of feasible design points or Pareto frontiers); 2) robust design and multidisciplinary optimisation; 3) design for reliability. We advocate and state in this paper that these approaches must be used in that order of increasing complexity. Indeed, applying an approach allows one to quickly figure out inadequacies with performance specifications or initial allowable bounds of design parameters and then to backtrack or to refine the design issue before proceeding to the next stage or approach. We illustrate that phenomenon by successively applying the three approaches on a dimensioning issue of a two-member truss structure. We clearly show that the successive optimal designs obtained are notably different, but that the optimal point obtained in a given approach is used to explore its surroundings within the next approach.
