Innovating comprises generating offers that make the preexisting ones obsolete. It implies in the creation or recognition of new forms of differentiation, the Opportunities Identification (OI). These may be due, among others, to new solutions or new problems to be solved, the latter a less explored path in the Product Development Process. There are studies aimed at systematizing OI, but present a discreet behavior in front of intuitive approaches. These rely on individual talent, a non-unanimous resource. As innovation is time-sensitive, there is room for artificial stimuli to intuition, which relies on the need for a close understanding of the phenomenon. This paper presents the descriptive research outcomes from a broader prescriptive study, which adopted the Design Research Methodology structure. Because OI is primarily a cognitive process and difficult to observe by a third party, one of the researchers submitted himself to the experience and recording of the phenomenon. The experience constitutes a unique case of OI accompanied during 2590 days. During this time, the study recorded 137 potential opportunities (units of analysis) by serendipity. Through the interpretation of the experienced phenomenon, the results comprise three perspectives: i/to the interaction of influence factors pointed out in the literature; ii/to the opportunities emergence; and, iii/to the opportunities identification. It is evident the challenge of considering opportunities as problems by its tendency of incubation. The work presents new research questions, hypotheses, and explanations valid to the case that potentially stimulate new exploratory or confirmatory researches or both.
This paper shows a study of correlation between EDM´s parameters with the level of superficial defects development, which can lead to premature failure of die cast mold machined by EDM. The correlation of parameters was determined through experimental matrix that uses the DOE methodology (Design of Experiment). In order to evaluate the surfaces of some machined samples a stereo optical microscopy, SEM (the scanning electron microscope) and a micro hardness profile machine were used. The results show that in the worst machining condition, which is caused by association of long electric discharge pulse time-on and graphite machine-electrode, it is possible to minimize the amount of surface defects, without applying a subsequent machining process such as polishing, just using the reduced time-on´s electric discharge pulse, copper electrode and dielectric fluid with base of hydrocarbon.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
