A general (male related) design approach
In the previously mentioned resettlement project near Udon?Thani in Thailand, the crank was fastened onto the wooden axle of the pump with the use of a wedge. In earlier projects this had proved to be a sturdy and reliable construction, which was also easy to make. It was appropriate because similar wedges were locally used in the construction of the plough.
When, after a year, this crank developed a crack, the woman expected her husband to repair it. The man, however, did not consider this part of his responsibility.
As a result, the crank became looser and looser, and finally it was impossible for her to pump enough water for her vegetable garden.
