The first thing to know before entering fully into the establishment of the meaning of the term contraption is its etymological origin. Specifically, it is a word that derives from Latin and is the result of the sum of two clearly defined components:
-The noun “ars, artis” that can be translated as “skill”.
-The verb "lugere", which is equivalent to "crying".

That goes to show that, at first, gadget was synonymous with "mock crying." However, later, it was used as we use it today.
The idea of contraption usually associated with a ruse , a trickery or a scheme which is carried out with the intention of achieving a objective . The concept can also refer to a mechanism that carries a certain complexity.
For example: "The government appealed to a legal contraption to make the decision without the approval of the senators", “The new electronic gadgets that teenagers use for entertainment never cease to amaze me”, "The possibility of participating in an alleged raffle is nothing more than a gadget to collect information from users".
However, we cannot overlook either that, at present, the term kitchen gadgets is used. It is used to refer to the entire set of utensils that are used to prepare a wide variety of recipes. Specifically, they are the ones who contribute to performing tasks much more easily within that sector.
Thus, for example, they are kitchen gadgets from a cherry heartbreaker to smart weights through the vegetable dehydrator, the immersion circulators ...
In the same way, we also find homemade gadgets that have been appearing in the market in recent years and are intended to make life at home easier. Among them are the alert that the refrigerator is missing some food, the light bulbs that connect to the music, the key finder ... And all that without forgetting the many others who come to bet on home automation in order to find the largest home comfort
In general, the notion of contraption is used disparagingly. Suppose that, in the context of a judicial process, a man who is accused of killing his wife must appear to testify before the judge. His lawyer, however, alleges that his defendant is not in good health and, therefore, asks to postpone the declaration based on a certain law . For the prosecutor, that request for postponement is a contraption of defense to gain time and build a stronger strategy that favors impunity.
In the field of computing , it is called a contraption or widget to an application that facilitates access to the most used functions of a system or that provides information graphically and directly. These gadgets help save steps and eliminate certain actions that, thanks to them, are unnecessary. A widget, to cite a possibility, can present the weather data on the screen of a computer (computer), preventing the person from entering a website to consult them or turn on the television for that purpose.
