The basic nylon Tie Wrap is widely used in the electronics and mechanical industries and is avail- able in many forms from short to long and very nar- row to wide. It is a simple piece of hardware, typi- cally molded from nylon, designed to peripherally clamp things together. It is comprised of a band with perpendicular grooves which mates into a con- finement head containing a paw1 that locks into the grooves. The paw1 is a hinged extremity that allows the passage of the grooved band in one direction, however restricting it movement in the opposite. In most applications, the amount of tightness and hold- ing reliability is not very crucial. However, one draw back with conventional Tie Wraps is the abili- ty to use them in more critical applications such as in the medical industry, aircraft industry or in an application where a similar latching concept gets reconfigured into a mechanical latching device. Our idea originated during the development of a preci- sion latching device. A problem can occur when the resolution of the grooves on the tie wrap band do not have a fine enough resolution. Typically you tighten a cable tie to a moderate tightness and the Paw1 locks into the last groove that it can fully engage. Should you need a tighter containment, advancing to the next groove could over stress the nylon to breakage or just near breakage which cur- tails reliability. This suggests the need for a device that has greater variability. The special need for this extra accuracy without sacrificing strength can be achieved easily by reconfiguring the standard tie wrap with the Staggered Paw1 concept.
