In his work Philipp combines traditional knowledge with contemporary technology to new, innovative concepts. For him, design goes far beyond the form of an object, it becomes the intersection of social, technical and ecological issues and is therefore a key element in our globalized world. He paraphrase the contemporary role of a designer as an active observer. Different to a passive observer which analyses and describes a situation he describes the active observer as one that analyses a situation, processes it and most important acts on it.
