When everyone wears a backpack, the length of both bag straps is different. The problem is that it is difficult to adjust the length of the left and right sides, and even if the length of the left and right sides are the same, the length of one side is increased or decreased during the activity, resulting in an imbalance. Especially for growing children, different lengths of both bag straps can cause left and right shoulder height changes and spinal deformations. We applied the principle of bifurcating strings at the midpoint of any length. Adjust the overall length of the strap and make the two straps equal in length through a passage that specifies the middle point. The strap length of the bag is adjusted by pressing the control button and pushing and pulling the handle. We have considered about the design that can fit both bag straps easily. Then we thought that if the two straps were naturally matched, it wouldn't need a guide. We have found this principle which makes both straps same length. It was inspired by origami, threading, playing, crane hooks and applied to design.
