Digital sketching and haptic sketch modelling during product design and development

During the practice of industrial design, digital methods are used to support the generation, development and specification of creative three dimensional (3D) form. Despite the increasing capabilities of digital methods, the distinctive nuances of current practice continue to use non-digital methods, particularly during the creative concept generation activities. This paper reports on a research project that combined emerging and established digital design technologies to define an approach for total 'Digital Industrial Design' (DID) that employs only digital methods (e.g. no pens/paper) with no post-process finishing (e.g. smoothing/painting of rapid prototype parts). The paper concludes that DID has the greatest potential for change and benefit during concept generation, where haptic feedback modelling and monochrome 3D printing have the capacity to replicate some of the qualities of tactile formgiving associated with workshop-based sketch modelling. To maximise impact, the case study was translated into in a web-based resource. Copyright © 2015 Inderscience Enterprises Ltd.
