The mothers of invention:

Hello I am Ainara, here I am show you some inventions, I hope you like it:

An invention is a unique or novel device, method, composition or process. It may be an improvement upon a machine or product, or a new process for creating an object or a result. An invention that achieves a completely unique function or result may be a radical breakthrough. Such works are novel and not obvious to others skilled in the same field.

For example:

dishwasher is a mechanical device for cleaning dishes and eating-utensils. Dishwashers can be found in restaurants and private homes. The dishwasher was invented by Josephine Cochrane in 1886.

 A diaper or nappy is a kind of underwear that allows one to defecate or urinate in a discreet manner. When diapers become soiled, they require changing; this process is often performed by a second person such as a parent or caregiver. Failure to change a diaper on a regular enough basis can result in skin problems.
Diapers are made of cloth or synthetic disposable materials. Cloth diapers are composed of layers of fabric such as cotton, hemp, bamboo or microfiber and can be washed and reused multiple times. Disposable diapers contain absorbent chemicals and are thrown away after use. Plastic pants can be worn over diapers to avoid leaks, but with modern cloth diapers, this is no longer necessary. Disposable nappies were invented by Marion Donovan in 1950.

The nylon stocking:
stocking (also known as hose, especially in a historical context) is a close-fitting, variously elastic garment covering the foot and lower part of the leg. Stockings vary in color, design and transparency. By analogy, the term is also used to describe a type of horse marking in which the white coloring extends from the horse's hoof to just above the knee.

Other examples:

The light bulbs are use specialy to last only a certain number of hours. It would be possible  to make light bulbs that lasted forever, but then the manufactures wouldn't make so much money.

Although penicillin was discover by Alexander Fleming, he didn't know how to make it into a medicine. It was first made into a medecine ten years later, by an Australian scientist Howard Florey.

Or the bullet-proff vest, theTipp-Ex, the biro, the washing machine or the windscreen wipers:
