Hollow structure snap-fit design embedded with shape memory polymer sheet

Active disassembly uses innovative components within the product design to promote self disassembly as natural decomposition. The use of smart materials, more specifically shape memory alloys and shape memory polymers, has been extensively documented. However, the difficulty of reusing those components with smart materials is becoming a problem in disassembly processes during regular product repair and maintenance. In order to improve the reusability of the components, the authors design a hollow structure snap-fit embedded with shape memory polymer sheets. Theoretical simulation and prototype testing are presented in this paper to demonstrate the advantages of the new snap-fit design.
