Safe driving on snowy and icy roads remains a critical engineering challenge. Existing anti-skid systems are often impractical, time-consuming, and not user-friendly in emergency situations. In this study, a next-generation solution called the Octopus Skid Chain (OSC) is presented, designed for easy installation and removal without requiring professional expertise. The system uses a tensioning wire rope mechanism, and octopus-like arms with fingers that grip the inner sidewall of the tire, enabling secure and slip-free motion over harsh winter terrain. A variant of this system, named the Tire Protection System (TKS), uses the same tension mechanism but is modified to serve as a protective shield against external threats such as landmines and bullets. Both systems feature a modular design and can be adapted to various vehicle types, offering multifunctionality in both civilian and military contexts. Finite element analysis of the TKS system under a 500 N static tensile load showed a maximum equivalent stress of approximately 400 MPa on the wire rope and total deformation below 0.7 mm, confirming the system’s structural safety and performance. The proposed OSC and TKS systems provide innovative, high-efficiency solutions for vehicle traction and tire protection in challenging terrain conditions, combining ease of use, adaptability, and mechanical reliability.Safe driving on snowy and icy roads remains a critical engineering challenge.
