Crafting with Kids

Today, if you pick up a packet of wiper blades and deliver them a basic visual observation they will appear to be almost undifferentiated from the initial proto types designed all the way back at the beginning of the century. But this does not tell the complete story, during the course of its development the wiper blades has seen a series of alterations and will continue to develop well into the future. The first thing to change was the type of material the wiper blades was assembled from brush; this model was made by Mary Anderson and patented in nineteen hundred and three. Since then, in the intervening time things such as rubber have come to the fore front of wiper blades design. The arguments for this are straight forward, rubber is cheap, ok to manufacture and is bendy and water resistant. The next thing to alter on the basic wiper blades design was the transition from manual hand cranked wiper blades to the latest steam or gas powered vacuum pumps.

The main issue with this advance is that the speed of the wiper blade was basically tied to the revs of the engine. If the car was going at full pelt the wiper blade speed crawled to almost a entire halt making for some very perilous driving days in the rain. The following addition was also to solve this danger, the introduction of electric motors driven by batteries charged from the motion of the engine were to provide the answer and give on tap on demand power when ever it was needed. More importantly, the electricity with the invention of alternating current could produce a abiding stream of power making sure the wiper blade went at a constant pace disconnected from the revs of the engine itself. One of the most recent and exciting developments in wiper blade design is the flat wiper, numerous factors have conspired to encourage developers to try something different.

Things like lack of space on the bonnet, reliability, safety and aero dynamic drag have coerced the manufacturers to have a rethink of this old basic wipers design. The flat wipers is in part a response to the global environmental difficulties we face today as a collection planet; the flat wiper will radically reduce the amount of fuel used and is therefore vital in the contribution against global warming. This new type of wipers has a much decreased profile than standard wipers styles and as a result they make a striking first impression which will leave the audience gasping. The new style of wipers has many practical benefits as well, the arm is highly resilient to the wear and tear generated from alternating hot and cold climate conditions like the alternating of the seasons from winter to summer each year. Another article of their competence is that they are very low in drag which means they will make the car go faster and have a cut above mileage as well. These days many European car firms are fitting wipers as standard, on day I envision a time when all windscreen wipers attached are of this variety.
