The Need: A quick, easy way of lowering bricks into the well.
The Dutch bricks are heavy--they can weigh up to 40 kg (90 lbs).
The well can be very deep; throwing or handing the brick down to
the mason simply isn't possible. The best way to get the bricks
into the well is to lower them down on a rope, using a pulley. Currently,
the rope is tied around the brick; this requires the mason to untie
it at the bottom.
The bottom of the well is a very confined space. Ideally, a mason
would have lots of room to move around, store bricks,etc.; in the
case of a well, however, every cubic foot of elbow room is another
cubic foot of soil and rocks that has to be dug out and excavated.
Consequently, digging is minimized, as is maneuvering space at the
bottom of the well. The only space the mason has is over the well
itself. His feet, however, have to remain outside the well (or else
he'll fall in!), so he has to counterbalance anything he carries
by throwing his weight backwards--similar to a pregnant woman arching
her back
Having received the brick, the mason has to untie it from the rope.
There isn't really any room next to the mason to place the brick;
and even if he did have space to put it down, that would mean picking
it up again--another backbreaking step. In most cases the mason
clutches the brick against his body while untying the rope--a most
uncomfortable process.
Here I saw an opportunity to help the masons in their everyday
work by creating a tool that would allow them to maximize their
productivity while minimizing their back strain.
