Explaining the Notion of Hermeneutic Phenomenology in Product Design

Hermeneutic phenomenology is the establishment of existential relations. How these relations can be manifested in human being in the world is one of the most important concerns of philosophers, including Heidegger - the famous German philosopher. Hermeneutic phenomenology seeks to understand the experience of life and use it to improve conditions. To this end, the designer can provide a design in which the prior experiences and concepts are used to serve the basic needs of the product (the existing being). Certainty does not matter in the nature of hermeneutic phenomenology, but also its work is to describe and interpret the human experience in the world. So this research provides a description of phenomenology that can be linked to the world of products by applying it to the product design process. This paper intends to provide an interpretation of phenomenology that can be considered and implemented in the design process. In this regard, this notion is further clarified by elucidating certain steps from it that include 1.Temporality 2.Establishing a meaningful relationship with having-been, presence and futuristic 3.Establishing a network of existential relationship between human and product 4.Establishing a hermeneutical relationship 5. Disclosedness. The result of this paper makes it clear that not only can use the phenomenology approach in product design, but also the case studies show that the use of this method during the industrial design history has been able to influence the success of products in relation with users.
