Description
Dyson's innovative washing machine Add ANSYS DesignSpace and its add-on module ANSYS DesignXplorer to your CAD package.

For the first time, simulation iterations match the rapid pace of parametric CAD iterations.
 
With ANSYS DesignSpace and ANSYS DesignXplorer at the front end of your product development process, you are free to explore and evaluate multiple design alternatives, quickly and easily.
  
Dramatically shorten iterations. Streamline design. Reduce costs. Now that's intelligent design.
 
Conventional wisdom states that if an object isn't broken, there is no need to fix it. However, even in today's high-tech world, companies needlessly expend exorbitant amounts of time, energy, and money breaking their own products.
 
Traditionally, this occurs once these products are designed, and prototypes are built and tested. When the prototypes fail to perform under the right conditions (i.e., they break), they must then be redesigned, rebuilt. and retested. This cycle repeats until just the right balance is struck.
Dyson Ltd. of Tetbury Hill, Malmesbury, U.K., implemented ANSYS DesignSpace(R) to conduct easy and accurate simulations to verify load handling and to optimize the design of an innovative washing machine that uses a single, high-performance sports car bearing to support the drum instead of two lower-grade bearings. Using this front-end simulation strategy, the company was able to run through hundreds of designs before settling on suitable candidates to check physically, saving time and money by eliminating costly prototypes.

Although this process saps a significant amount of corporate resources (just take a look at any corporate R&D expenditures), companies choose to stick with it simply because they believe there is no viable alternative.
 
But there is...
 
Adopting a computer-aided engineering (CAE) design strategy can save considerable amounts of time and money in the development of products. In particular, implementing design simulation and analysis in the critical early stages of the process expedites the validation of design assumptions and the prediction of product performance before committing to expensive prototype construction. This helps companies realize cost savings in prototype materials, man-hours, and scrap disposal as well as significant reductions in warranty issues.
 
Large and small companies in various industries have already realized significant benefits through the implementation of a front-end analysis strategy. For example, Eaton Corp. was able to cut their development costs an average of 30 to 50 percent and reduce the average number of design iterations from six to two. Meanwhile, Stein Design, a small United States design firm, improved the strength of a particular component typically found in commercial coffee makers, vending machines, and like devices by as much as 220 percent.
 
In addition to the opportunity for lower costs, increased revenue, and greater market share, a front-end analysis solution affords design engineers an opportunity to expand their personal skill set and heighten their contribution to product innovation.
 
ANSYS Inc.'s front-end analysis solution is developed exclusively for designers and engineers. It offers the broad range of functionality, flexibility, and intuitive operation essential to give product design professionals the ability to perform elementary structural and thermal analyses, quickly.
 
ANSYS DesignSpace offers users the advantage of the ANSYS Workbench Environment, a one-of-a-kind user interface similar to many popular CAD packages. The Workbench Environment's numerous toolbars, automated features. and wizards allow design engineers of all skill levels — entry through expert — to become familiar with vital operations at their own pace.
 
Bringing simulation and analysis to the design engineering level of your company's product development system lays the foundation for a fast, efficient, and cost-effective process.
