Urban design, between challenging urban controls and managing diversity and disagreement ‘’ Street Furniture designs ‘’ as an example

Civilizations are built benefiting from the development of knowledge and the cross-fertilization of their scientific paths, and this development is evident in various images and manifestations that predict the sophistication, richness and diversity of societies reached. Perhaps one of the most prominent manifestations of human creativity in our time is the urban design of cities and the furniture that is displayed in their squares and spaces, which has become a living witness to the essence of this or that civilization, and a mirror of what its people have reached of elevation and sublime. This contemporary period witnessed the emergence of various trends that branched out from the science of urban design and its practices. These trends enriched the criticism of its origins and pushed its philosophical journey to a new horizon. This is related to the peoples' social, ethnic, and cultural identities.
In light of this richness of knowledge, it is inevitable to expose the reality of the urban design issue and it’s relation to "street furniture". By shedding light on some ambiguous aspects related to the emergence of knowledge tensions, the intensification of social clashes, and the conflict of interests between political forces that could have been in conflict with the freedom needed for creativity and innovation. However, and contrary to what was expected, these discrepancies led most of the designers to try and adapt to each of these issues raised related to the public sphere.From this multi-faceted angle, this scientific paper addresses the problem of designing "street furniture" between the challenge of urban controls and managing the mosaic of diversity and difference. This article discusses ways to face urban challenges for the designer of "street furniture", dealing with design management at the operational and strategic levels, and concentrating on the most prominent contemporary trends in urban design and its furniture, and from these trends, we mention:
 The communicative trend, in which it branched two trends:
• Utilitarianism, whose origins are inspired by William James, or what is called instrumentalism according to John Dewey's philosophy.
• The direction of rationality based on the communicative Hiebermas theory.
 Fair direction :
We sought to analyze each of these trends with the applied scientific methods that the designers adopt as they adress to unresolved urban theses.
