1. The following image is the patent drawing of the first windscreen wiper, invented by Mary Anderson, which she herself registered in 1903. Obviously, its shape is very different from today's windscreen wipers. However, there are still parts that are very similar to the original ones Mary Anderson devised. Which parts have remained virtually unchanged since her conception?

2. Carry out a formal and functional analysis of a current windscreen wiper like the one shown in the second image of the previous section.

Observations and context

We can relate this invention and its inventor Mary Anderson to other everyday inventions made by women in the late 19th and 20th centuries: the dishwasher (Josephine Cochrane), the hypodermic syringe (Letitia Geer), the coffee machine (Melitta Bentz), the disposable nappy (Marion Donovan), the lifeboat (Maria Beasley), the ink pen (Bette Nesmith Graham) or the bra (Mary Phelps Jacob).

Description
