Hook-and-Loop Reins Connector for Dragging Prevention

The patent applies the dynamics principle by using a hook-and-loop fastener system that transitions from a connected state to a separated state based on applied force. The control lines remain securely connected during normal use but automatically separate when a threshold force is exceeded, such as when a rider or driver is dragged. This dynamic behavior resolves the contradiction by making the connection strength conditional rather than fixed.

The patent applies the parameter changes principle by designing the hook-and-loop fastener with specific tensile strength parameters that are lower than the force required to drag a fallen rider or driver. The fastener is engineered to fail at a controlled force threshold, changing the mechanical parameter of connection strength from high (traditional buckle) to a controlled lower value that prioritizes safety over secure connection.

The hook-and-loop fastener provides dynamic control reliability that adapts to operational conditions. During normal riding or driving, the fastener maintains a secure connection ensuring control reliability. When abnormal conditions occur such as entanglement and dragging, the fastener automatically releases, providing the necessary ease of operation for safety. This resolves the contradiction between maintaining control reliability and enabling release capability.

The hook-and-loop fastener acts as an intermediary between the control lines and the rider/driver. It provides a controlled connection that can transmit normal operational forces while failing safely under excessive force. The fastener mediates between the need for secure connection and the need for automatic release, resolving the contradiction by introducing a force-threshold-based intermediate state.

The patent applies mechanics substitution by replacing the traditional buckle mechanical system with a hook-and-loop fastener system. The buckle relies on interlocking metal components with high strength, while the hook-and-loop fastener uses fibrous mechanical interlocking that provides both connection and controlled failure. This substitution maintains relative simplicity while adding the critical safety function of automatic release under excessive force.

The hook-and-loop fastener embodies the principle of disposable safety components. The fastener is designed to be replaceable rather than permanent, accepting that it may fail under extreme conditions. This approach prioritizes safety over durability, allowing the fastener to be replaced after use rather than requiring complex recovery mechanisms, thus maintaining device simplicity while adding safety functionality.
