The conceptual design presented in Figure 6 represents an incremental shape evolution from one of the current shape archetypes for vacuum cleaners. As growing automation and convenience for consumers proceeds, industrial designers are also bound to play an important role in establishing links with past era designs, and as such provide consumers in this digital age, objects that enable reminiscing of past eras, with a shape that cues their

There are limitations in the methodologies presented in this chapter, which will be alleviated if the prerequisites that are necessary for their effective use are met. The methodologies and categorization are only deemed suitable for application in products that incorporate technology for their operation. It is important for the deployment of these methodologies to have knowledge on emerging technologies and on the history of the product or devices that have been used for implementation of a particular

There are some historical cases of technologies that have failed, and that were put aside, because there was an arrest of the market by a technology already implemented. This happened for example with Sony's Beta video system, which was of higher quality than Philip's VHS (Video Home System), but the latter prevailed (despite the better quality of the Beta video system), because films existed in greater quantities in the VHS format, which led to the decrease of availability of films in Beta format. There is no guarantee that the three

Sheet metal is commonly used in the automotive industry. The requirements for developing approaches for manufacturing automotive panels have become increasingly important as carmakers seek to shorten their time to market. However, designing and manufacturing mold dies for automotive sheet metal panels is time-consuming as several processes use the trial-and-error method. The die design period for one sheet metal panel is usually a few

Along with advances in Computer-Aided Design (CAD), simulation of interference checking can be conducted using a three-dimensional solid model, and Computer-Aided Engineering (CAE) software can be used to simulate and analyze die face to accelerate the
