“…Connecting rod B (9) and connecting rod C (13) compose the flexible connecting mechanism. One end of connecting rod B ( 9) is rigidly connected to inner drum plate (2), while the other end is hinged to the lower end of connecting rod C (13). To avoid the motion interference between inner drum plate (2) and external drum plate (3), connecting rod C ( 13) is not only designed as a bending rod but also indirectly connected to external drum plate (3) by the combination of sliding sleeve A (11), sliding sleeve B (12), and cross (10).…”

“…The process of conceptual design can be characterized as defining function specification, seeking principle solutions and finally formulating physical structure, and the involved engineering attributes (i.e. function, principle, and structure) can be used for the representation and comparison of design outputs, and further to find design analogies from them, such as in the researches by Qian and Gero, 10 McAdams and Wood, 11 Sartori et al, 12 Fantoni et al, 13 and Agyemang et al 14 2.

By the knowledge transferring in different areas, analogical design has been considered as a powerful approach to promote the generation of novel ideas in product conceptual design. An efficient representation scheme for design knowledge is vital to implement analogical transferring. In this article, inspired from the structure mapping mechanism of analogical reasoning, a structure mapping–based representation was proposed to support designers to search and use design analogies. This representation can provide designers with insights into the structural information of knowledge situations, and consequently designers are able to implement the corresponding design analogy search at the level of the structural similarity, rather than the functional or superficial similarity. Based on this new representation scheme, a structure mapping–based analogical design framework was developed. In this framework, patents are used as the source of analogical knowledge, and the relational structure–based representation for the patent knowledge is created using the advanced natural language processing tools/algorithms. Next, the search of design analogies is implemented by means of the vector space model, and a new structure mapping–based concept generation model can finally guide the designers to use design analogies. An industrial case and a compared experiment were carried out to verify the feasibility and effectiveness of the proposed framework.

Functional technology foresight. A novel methodology to identify emerging technologies

The speed and complexity of the technology evolution faced by modern societies need new approaches to the analysis and understanding of the world. Indeed, an exclusive focus on technological goals can miss to recognize all the stakeholders of a technology and address real user needs; moreover, on the one hand low signals are becoming more and more important in fast evolving markets, on the other hand the excess of hype, fashions, or vested interests sometimes deeply alter indicators. However, the so called Big Data promise to be a huge low cost set of valuable information, available and affordable to all (SMEs included). But, analyzing them is not trivial especially if we deal with academic papers and patents. To tackle these issues, the present paper proposes to apply a powerful methodological tool called Functional Analysis to the Technology Foresight process. Actually the rigorous study of the functions, that an artefact should perform to satisfy the user needs, provides a universal and thus unifying point of view, which is able to correlate the user perspective on the product with its technical features. Functional reasoning has been applied to (i) detect possible patterns of development, spotting missing elements and highlighting strengths as well as potential sources of failure; (ii) to enhance traditional bibliometric tools such as the analysis of S-curves and (iii), integrated with a natural language processing analysis toolchain, tailored for patent documents, to identify emerging technologies. The paper describes the functional approach to technology foresight activity, presents how to integrate it with text mining algorithms and experts' domain knowledge, and finally discusses its benefits in the context of Technology Foresight also from an economic point of view, showing that oresight is affordable also for Small and Medium Enterprises.

Automated handling of heavy deformable goods, due to their challenging material properties, sets a benchmark for handling sacks, such as bags of fabrics, synthetic packings, papers filled with coffee, cereals and plastic pellets. The paper focuses on the handling of jute coffee sacks.Nowadays the manipulation of jute coffee sacks is performed manually, because of the lack of specific grippers able to grasp this type of object. Hence, a set of concepts have been designed and developed to test the functionality of new devices, specifically intended to be used for the grasping of jute coffee sacks. Grippers have then been ranked through a Multiple Attribute Decision Making (MADM) method, in order to identify the best gripping tools for the handling of non-rigid materials. Finally, one of the most promising grippers has been designed and tested on real scale jute coffee sacks.
