Juicing cone prototype by Breville Design

Object No. 2006/16/5

This prototype for a citrus press is an example of one of many rapid prototyping techniques that have become widely used by product designers all over the world. Rapid prototyping enables designers to quickly test and refine their ideas in three dimensions before they are presented to the tool maker or manufacturer. This prototype was used by the designer at Breville to juice citrus fruit in a working prototype and determine the optimum shape for the reamer. 3D computer data was used to make more than 20 prototypes of the juicing cone or reamer. These were tested and modified by hand to obtain the perfect shape for juicing all types of citrus fruit. Each prototype was made overnight in a fused deposition modelling (FDM) rapid prototyping machine in the Breville design studio. The designer modified this original prototype by hand and then digitally scanned it back into the 3D computer model to complete the final design. The 3D data for the final design was sent to the toolmaker and manufacturer in China for testing and production. The development process for the Citrus Press is typical of contemporary products designed in Australia. The local designers began with sketching and hand made models to develop initial concepts for the form of the product and the patented handle mechanism. 3D computer modelling and rapid prototyping were the primary tools used to develop all aspects of the device. The Breville 800 Class Citrus Press is designed to extract juice from the smallest lime to the largest grapefruit in seconds without changing the juicing cone. The patented arm mechanism is easy to use, and allows the fruit to be juiced quickly with little effort. A double safety switch ensures the juicing cone does not spin unless the fruit is loaded and the arm depressed over the fruit. The Breville 800 Series Citrus Press was awarded an Australian Design Award in 2005 and received the Powerhouse Museum Selection Award in 2005.

PRODUCTION

Notes

This plastic prototype of the juicing cone or reamer for the Breville Citrus Press was designed by Keith Hensel using 3D computer modelling and made using the fused deposition modelling (FDM) rapid prototyping machine in the Breville Design Studio at Botany, NSW, Australia, in October-December 2003. It was used by the designer to juice citrus fruit in a working prototype to test the optimum shape for the reamer. The designer modified this original prototype by hand. The modified shape was then digitally scanned back into the 3D computer model to complete the design. The Citrus Press project was initiated by John O'Brien, the late chairman of Breville and son of the company's founder, Bill O'Brien. John O'Brien identified a need in the marketplace for a citrus juicer that was easy to use. The existing models required a significant amount of force and dexterity to operate. The Breville Citrus Press was modelled and tested using a combination of 3D computer modelling, sketching and hand-made models. Keith Hensel used sketching to develop initial concepts for the form of the product and the patented handle mechanism. Simple cardboard cut-outs were also used to test the handle mechanism. 3D CAD modelling was used to further develop all aspects of the device. An early form model was hand-made in wood, and the first working prototype was also hand-made using wood and other components. The 3D computer data was used to make more than 20 prototypes of the juicing cone or reamer. These were tested and modified by hand to obtain the perfect shape for juicing all types of citrus fruit. Each prototype was made overnight in a fused deposition modelling (FDM) rapid prototyping machine in the Breville design studio, ready for the designer to test and modify the next day. Designers at Housewares International create all their products using 3D computer modelling. Products are designed in 3D on computer, and the data sent to a prototyping machine to produce a one-off for testing. Once the design is finalised the 3D data is sent to the toolmaker and manufacturer for testing and production.

HISTORY

Notes

This prototype was used by the designer to juice citrus fruit to test the optimum shape for the reamer. It was lent to the Museum for display in the exhibition 'Sydney designers unplugged: people, process, product' from 6 August to 9 October 2005. The Breville 800 Series Citrus Press was awarded an Australian Design Award in 2005 and received the Powerhouse Museum Selection Award in 2005. Over 190 products were entered in the Australian Design Awards in 2005. The judging panel recommended 49 of these products receive an Australian Design Mark and of these, 20 products for an Australian Design Award. The products receiving the Australian Design Award were announced at a dinner and awards ceremony on 22nd April at Melbourne Museum. At this ceremony the recipients of the Powerhouse Museum Selection awards for 2005 were also announced. In 2005 the Breville brand was owned by the Australian company Housewares International. Breville was founded in Melbourne in 1932 and for over 40 years had been researching and developing new appliances. The Breville studio works closely with the Housewares International - Homewares design studio also located at Botany. The two studios work with local marketing, sales and engineering staff to create electrical appliances and homewares that are manufactured in Europe and China and sold all over the world.
