I need to rename an uploaded document by adding some additional information to its file name, currently I do this with an Event Receiver ItemAdded wiring up on Document Library, using code 

    SPListItem material = properties.ListItem;
    material["Name"] = RenameFile(material["Name"].ToString());
    material.Update(); 
    //material.UpdateOverwriteVersion(); //same issue

This would works fine until the same file is uploaded again, after renaming the error "the specified name is already in use" will occur although I have enabled document version control.

Do I need to create a new version programmatically? if so, how am I supposed to do it, can someone shed some lights on this? Any help is deeply appreciated.

I think you need to check the document out and then back in
