Tying Path Design of a Belt-Like String to Bind Wire Harness

In aircraft manufacturing, wire harness bundling is performed manually, requiring significant time and labor. Therefore, this study presents a new design for bundling tools aimed at improving the efficiency of the bundling process. A belt-like string used for bundling is modeled using a discrete model, and constraints based on the knotting method are formulated. Under such constraints, a path of the string to knot it is optimized. From the obtained path, a mold capable of actual bundling was fabricated, and the resulting knot formed using this mold was consistent with the tying methods required for wire harness bundling.
