Tool Lanyard Application in Smart Dog Walking Systems

Product Requirements:

With strict urban dog management regulations, a metropolitan community mandated anti-escape devices for all dogs over 20kg. Traditional nylon leashes showed 42% failure rate under 30kg tension and lacked smart monitoring capabilities. Development requirements included:

· Instant load capacity ≥500kg

· Canine bite resistance Class 4

· Integrated geo-fencing module

· Ergonomic handle design

Engineering Solution:
Triple-layer 304 stainless steel tool lanyard:

00001. Core: 7x19 aircraft-grade steel cable (Ø2.5mm)

00002. Buffer: Thermoplastic polyurethane (TPU) injection molding

00003. Armor: Ultra-high molecular weight polyethylene weave

Technical Specifications:

· Smart segmentation:
