L'invention concerne un système d'étui intelligent (100) pour protéger un objet fragile (E). Le système d'étui intelligent (100) comprend un système de détection (101) comportant une pluralité de capteurs (206). La pluralité de capteurs (206) est conçue pour détecter la chute de l'objet fragile (E). Le système d'étui intelligent (100) comprend un système de déploiement (102) fonctionnellement couplé au système de détection (101) et un système de protection (103) fonctionnellement couplé au système de détection (101) et au système de déploiement (102). Le système de protection (103) comporte une charnière (302) pour monter le système de protection (103) sur l'objet fragile (E) et un élément de protection (303) couplé à la charnière (302). Le système de protection (103) est placé sur l'objet fragile (E) dans une relation non contrainte (U). Quand la pluralité de capteurs (206) détecte que l'objet fragile (E) tombe, le système de déploiement (102) déploie le système de protection (103) de façon que l'élément de protection (303) se plie pour recouvrir une partie de l'objet fragile (E) à l'aide de la charnière (302), ce qui permet de faire passer le système de protection (103) dans une configuration ouverte (O) à partir d'une configuration fermée (C). L'élément de protection (303) vient au contact d'une surface, absorbe l'impact et protège l'objet fragile (E). Dans un mode de réalisation, un système d'étui intelligent (100) complètement intégré à l'objet (E) est également décrit.
