The Patented Technology Innovation Portfolio on 4D Printer Using Theory of Inventive Problem Solving

The paper provides a comprehensive analysis of the patent literature about the evolution and development of 4D printing technology, highlighting its significant impact on the industrial and scientific domains. 4D printing, a progression derived from 3D printing, incorporates time as an additional dimension, enabling buildings to change, adapt, and respond to external stimuli autonomously. This review critically examines various patents, particularly identifying and analysing significant inventions, applications, and implications of 4D printing. Through a comprehensive examination of the intellectual property landscape, this scholarly article illuminates the path of development of the technology above and its potential to bring about transformative changes in various industries, including manufacturing and healthcare. Examining patented concepts, this study sheds light on the development, status, and prospects of 4D printing.
