Ces \u00e9l\u00e9ments sont essentiels pour \u00e9viter la prolif\u00e9ration des bact\u00e9ries, particuli\u00e8rement en milieu hospitalier. On en retrouve par exemple environ 5000 dans l\u2019h\u00f4pital Piti\u00e9-salp\u00eatri\u00e8re \u00e0 Paris.<\/p>

Bien qu\u2019un entretien tous les ans soit recommand\u00e9, le co\u00fbt et la complexit\u00e9 de maintenance le rendent rare. Et quand il est chang\u00e9, il est souvent enti\u00e8rement jet\u00e9, laiton compris, ce qui g\u00e9n\u00e8re beaucoup de d\u00e9chets. <\/p>

Le but \u00e9tait donc ici de concevoir un produit facilitant et r\u00e9duisant le co\u00fbt de la maintenance.<\/p>

Apr\u00e8s avoir interrog\u00e9 des professionnel des r\u00e9seaux d’eau dans des h\u00f4pitaux, H\u00f4tels et maisons de retraite, j’ai d\u00e9fini le besoin, g\u00e9n\u00e9r\u00e9 des solutions techniques et prototyp\u00e9 4 concepts.\u00a0<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t

Afin de trouver les meilleures solutions techniques \u00e0 notre probl\u00e8me, j’ai organis\u00e9 2 s\u00e9ances de cr\u00e9ativit\u00e9s qui ont permis de g\u00e9n\u00e9rer plus de 40 id\u00e9es.
