Qiuyu Li explains:
The delicate balance between the "intrinsic" and "extrinsic" elements is paramount in the creation of a successful design, with "intrinsic" denoting the designer's self-awareness, aesthetic sensibilities, personal preferences, and values, and "extrinsic" referring to the practicality, communicability, and client demands dictated by the external social environment. A good design necessitates the harmonization of these two aspects, as neither can be disregarded. It should be a reflection of the designer's self-expression and values, while also meeting the client's requirements and fulfilling the necessary utilitarian value.
