Scientists from the Max Planck Institute for Dynamics and Self-Organization have developed an advanced magnetic zipper for industrial and consumer applications that is immune against misaligned closing of both rows.
The design is based on permanent magnetic elements of different lengths as illustrated in Figure 1 (c,d). The pattern formed by the different lengths is such that in the case of positioning offsets, neighboring elements are generally repelled from the opposing rows. Thus, the automatic closing mechanism is only triggered when two matching pairs of magnetic elements are brought into contact by the user.
This simple but effective improvement increases the usability of magnetic zippers. Further it is a key technology establishing magnetic zippers for applications that demand user-friendly and reliable zippers, such as outdoor clothing, adventure backpacks or industrial applications.
