“…Conceptual design is one of the earliest stages of product development and is responsible for defining key aspects of the final product (Briede-Westermeyer et al, 2014 ). Designers commonly use freehand sketching to express conceptual design, which is a reflection-in-action process that occurs during design (Schön, 1983 ).…”

Sketching is one of the most important processes in the conceptual stage of design. Previous studies have relied largely on the analyses of sketching process and outcomes; whereas surface electromyographic (sEMG) signals associated with sketching have received little attention. In this study, we propose a method in which 11 basic one-stroke sketching shapes are identified from the sEMG signals generated by the forearm and upper arm muscles from 4 subjects. Time domain features such as integrated electromyography, root mean square and mean absolute value were extracted with analysis windows of two length conditions for pattern recognition. After reducing data dimensionality using principal component analysis, the shapes were classified using Gene Expression Programming (GEP). The performance of the GEP classifier was compared to the Back Propagation neural network (BPNN) and the Elman neural network (ENN). Feature extraction with the short analysis window (250 ms with a 250 ms increment) improved the recognition rate by around 6.4% averagely compared with the long analysis window (2500 ms with a 2500 ms increment). The average recognition rate for the eleven basic one-stroke sketching patterns achieved by the GEP classifier was 96.26% in the training set and 95.62% in the test set, which was superior to the performance of the BPNN and ENN classifiers. The results show that the GEP classifier is able to perform well with either length of the analysis window. Thus, the proposed GEP model show promise for recognizing sketching based on sEMG signals.

“…El análisis del constructo CO2, que da como resultado del análisis exploratorio determina la definición y significado del fenómeno del diseño conceptual y las implicancias consideradas desde la visión de diseñadores e ingenieros. Un factor coincidente, Hsu & Chen ( 2006), citado por Briede (2014), es considerar que la actividad de diseño conceptual es efectivamente la actividad más crítica y clave para el diseño de productos. La representación de esta actividad por lo general está presente en la mayoría de los modelos revisados en la literatura, algunas veces con diferentes denominaciones dependiendo del enfoque y dominio del diseño.…”

This paper presents a method to decompose three dimensional complex parts into readily available stock material to take advantage of advanced joining to build up a rigid assembly. The method generates many alternative assemblies by decomposing the solid geometry iteratively with cutting planes. Each assembly is then evaluated based on cost. The process continues until the developed search algorithm converges on a near optimal solution. Application of this method will reduce material waste, thus reducing per part processing time, energy consumption, and associated production costs. Example parts for a variety of metals show how the computational tool finds near optimal solutions for complex three dimensional solids.
