Hello!
This is my second entry for the Casabella "stringmop" competition.
The main principle is equal to my first entry, however this time I moved the pulley mechanism higher - on arm height. I also changed the way of reaching contraction of thespring - by rotation of the upper handle.
I think that this mechanical principle (same goes for my first entry) has a big potential because it surely is a totally new approach and hasn't been used before. Ofcourse there need to be done some additional work to bring this product on the highest manufacturabilitylevel possible, but I think I gave a good example of the features I have used. For the sake of manufacturability you could also avoid the usage of the helix shape and just use a straight one, the effect would be very similar.
Feedback is welcome!Regards.
