Conflict resolution of product package design for logistics using the TRIZ method

This paper is focused on the global logistics packaging issues at notebook new product introduction (NPI) stage. This study resolves the conflict problem of design attributes when considering product packaging design for logistics (DFL). First of all, this paper surveys design requirements and design attributes and their weights in terms of importance for notebook computer packaging design and then constructs a fuzzy quality function deployment (QFD) matrix. Using this matrix, we can collect information regarding the relationship between design requirements and design attributes in terms of linguistic variables from experts´ questionnaire. From the questionnaire, the fuzzy number of product packaging design attributes can be found using the fuzzy integral method, and the priority of design attributes can be obtained. Finally, we use the TRIZ (theory of inventive problem solving) method to find the improving features and inventive principles corresponding to the few top priorities of design attributes in order to solve the product package design conflict problem more effectively.
