Dynamic Controls produces most of the worlds powered wheelchair controllers and 50% of these are the Shark product range.  Earlier models, however, were designed without due consideration of design for manufacture and largely ignored the installation, service and parts stocking requirements that represent significant cost as volumes ramp to meet global demand.


Dynamic had several teams working on electronic software and industrial design elements of the product range.  Conceptual work was undertaken to trial DFM techniques and automation was a major driver in this.  inFact was involved in the mechanical engineering of the product and its manufacturing system.  Extensive testing both for environmental and compliance was undertaken.  The cost reduction programme and integration with electronics and supply chain requirements driving many of the hard to resolve issues.


Marketing drove customer requirements and it was during this development that it became obvious to inFact that a design front end to understand customer needs for outrselves was going to be a primary requirement.


Shark is Dynamic's most successful product range ever.  It has huge market penetration and many of the design solutions incorporated in these products have been carried into subsequent designs and have become embedded in many Invacare (parent) products.
