What is design? Redefining the geometry of a gear’s teeth as to improve its durability? We start a small step before that. We observe the whole picture, trying to see how the products we make interact with the user and the environment. Sometimes there are minor issues, sometimes problems are so large that they assume social relevance. When we address these last and try to find a solution, we call it “socially responsible design”.
Among the most common power tools for lawn & garden purposes, the chainsaw is by far the most potentially dangerous. According to the US Centers for Disease Control and Prevention (CDC), each year approximately 36,000 people are treated in hospital emergency departments for injuries from the use of chain saws. Medical costs for chainsaw injuries in the US amount to approximately $350 million per year.
We acknowledged the problem and thought the typical chainsaw is designed for lumberjacks’ needs rather than for home-owners’ applications—which range from tree-pruning to log cutting to after-storm cleaning. Hence our primary objective was to design a chainsaw that is safer for the novice and occasional user, but at the same time is also better adapted to the specific needs of home-owners. The resulting product is the Worx JawSaw, a chainsaw where the chain is enclosed in a blade cover which prevents unintended contact with the chain by the user, who has to have both hands on the tool grips in order to operate the saw.
Designed for the homeowner’s needs, the JawSaw is a much safer chainsaw that has the potential of contributing to a substantial reduction in the number of chainsaw-related injuries.
