The unbreakable Umbrella

  Have you ever gone out for a walk the day after a windy/stormy day/night and noticed on nearly every street/avenue the twisted carcasses of broken umbrellas? Umbrellas operate fine on rainy days where there is just light to moderate wind - that is they perfom their design function beautifully (keeping the rain off you). However on days when winds start to gust and squall, it is a full time job just trying fo keep the umbrella facing into the wind. At intersections/road junctions and in exposed areas the design flaw of the umbrella comes into play. An abrupt change in direction of the wind catches you off-guard, catching the umbrella and blowing it inside-out. If this gust is strong enough your brolly is busted instantly(hence the discarded skeletal remains (of the brolly) which are discovered the next day! Is it possible to design one which could automatically adjust itself to abrupt & violent changes in windflow? I would be interested in purchasing such a brolly!
