碩士 / 國立臺灣科技大學 / 科技管理所 / 105 / Knowledge has been the most powerful strength to promote economic development in the fast-changing generation. Product lifecycle becomes shorter, and traditional habits and customs are also transforming in different ways. Therefore, to understand the evolution of product design becomes very important. The study identifies the trajectory and development of designs in mobile phone. We also discuss the meaning of changes in mobile phone design patents, and find out the core assignees and the active countries in this industry.
Thais study collected data from USPTO with classification number D14/138. Total, we extracted 5,185 patent data, covering the period from 1989 to 2014, from WEBPAT. By using Main Path Analysis and Edge-betweenness Clustering can explain how the outlook of mobile changes in different periods, and also explore the main actors in the design knowledge network. We also construct the assignee network, patent citation network and country citation network to observe the linkages among different actors. From these three networks, we can sort out that 273 assignees in 24 countries participating in the innovation network of mobile phone designs.
The results showed that Finland, America, Korea, Japan and Taiwan are the central countries of design knowledge network. Moreover Nokia, Motorola, Sony Ericsson, Samsung and LG have strong influences of mobile’s design style. The main path results expressed that there are three stages of mobile’s design lifecycle. The first phase (1989-2001) is new product period, the second phase (2002-2011) is mature period, and the third phase (2012-2015) is standardization period. In addition, we identify five different clusters expressing specific characteristics and unique stylizes of mobile phone designs. The five design clusters include “Wireless Transceiver Tool Group”, “Wireless Folding Communication Group”, “Personal Handheld Assistant Group”, “Digital Slide Wizard Group”, and “Unlimited comprehensive Group”. The changes of mobile’s diverse and abundant styles seems to explains the linkages with social life turning to be colourful and full of imagination.
