Interactive Design: Then and Now

The aim of this work is the manufacturing of non-woven fabrics to be used as Filtering media. These fabrics were produced from polyacrilonitrile (PAN) and β-cyclodextrin (β-CD) solutions in dimethylsulfoxide using a horizontal electrospinning system with a flat collecting screen. The information from the experiments was statistically analyzed in order to define the process parameters (PAN concentration in solution, volumetric flow and applied voltage) needed for obtaining fibers with the smallest average diameters. First, PAN fibers were produced following a full factorial 3 3 experimental design and this information was used for preparing the corresponding Response Surfaces needed to define the best conditions for the production of PAN/β-CD nonwoven fabrics. The viscosity of the polymer solutions was analyzed using a rotational rheometer and a pseudoplastic behavior was observed, the diameter of the obtained nanofibers was determined using scanning electron microscopy. At the end, the polymer concentration (viscosity) and the volumetric flow rate were selected as the most statistically significant factors affecting the fiber diameter. Besides, uniform PAN and PAN/β-CD nanofibers with average fiber diameters between 200 and 500 nm were obtained.

“…Additionally, the evolution in Information and Communication Technologies (ICT) offers interesting approaches to implement reusable knowledge into decision-making. Literature in Interactive Design establishes that different disciplines may interact through new developments on the domain of knowledge engineering and through the exploitation of computational tools [9].…”

This article explores the applicability of heuristic rules into the decision-making processes involved in design practices, with the aim of generating a strategic approach for the fixation, tangibilization and re-utilization of knowledge within organizations. For this purpose, the research focuses on the creation of a methodological approach and a support tool that seeks to facilitate the introduction of heuristics into particular stages of the design process, such as concept development and architecture definition. This is achieved by providing an initial analysis of the design problem, and the definition of specific problem solving actions based on heuristics. This means that, with the aid of tools specifically developed for the method, the process will help design engineers explore several solution principles with applications previously implemented in diverse domains, thus triggering creativity in problem solving activities. This will enable a more diverse concept generation and a more detailed product development process. In addition, it will allow organizations to work with tools and procedures for them to ensure that emerging knowledge can be integrated to the proposed approach and reused in the future.

“…Interactive design is a mixture between modelling techniques, with the goal to center the design process on humans [11]. Technology plays a very important part on this.…”

The end result of this research is an application created using freely available tools applied to a case scenario to perform review meetings by different specialists in real time. Initial tests on the system have been made with Civil Engineering students showing that this virtual reality tool eases the burden of performing engineering drawings reviews that are traditionally done at the same geographical space.
