Innovation Solution
A multifunction device with a locking cam and pulley system that is compact, lightweight, and easy to operate with one hand, featuring a movable cam and pulley design that securely houses the safety rope, preventing slippage and allowing for quick and safe rescue maneuvers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple devices are combined to perform rescue operations, then the functionality and versatility are improved, but the device size, weight, and complexity increase
Solution Approach 1:
The patent combines multiple rescue devices (locking device, pulley, carabiner) into a single integrated multifunction device. The locking cam mechanism integrates with the pulley system and carabiner coupling, allowing all components to work together as one unified device rather than separate pieces of equipment.
Solution Approach 2:
The multifunction device is designed to perform multiple rescue operations including locking, pulley operations, and carabiner coupling. The single device can handle various rescue scenarios that previously required multiple specialized devices, making it universally applicable to different rescue situations.

3Ease of operation
If the device is made compact and lightweight, then the ease of handling is improved, but the safety features may be compromised
Solution Approach 1:
The device includes a retaining wall that proactively prevents the safety rope from slipping out before it can cause danger. This preliminary safety feature is built into the device structure, ensuring rope retention is maintained even in the compact design.
4Ease of operation
If the device structure is simplified to reduce weight, then the ease of operation is improved, but the risk of rope slippage increases
Solution Approach 1:
The device includes a retaining wall that proactively prevents the safety rope from slipping out before it can cause danger. This preliminary safety feature is built into the device structure, ensuring rope retention is maintained even in the compact design.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The device enables efficient and safe rescue operations by minimizing the risk of rope slippage and reducing the complexity of setup, allowing for rapid and accurate configuration, even in challenging conditions, while maintaining a compact and lightweight design.
Implementation Method 1
the cam is configured to rotate around a second rotation direction about a second axis of rotation perpendicular to the first direction, between a first position in which it throttles the first passage and pushes the safety rope present in the first passage against the abutment wall to brake or lock its sliding
Implementation Method 2
with a pulley adapted to facilitate the relative sliding between safety rope and device

AI summary
A multifunction device adapted to house at least one safety rope comprises a first fixed portion which defines a first passage for the rope; a first rotation axis; a second portion movable with respect to the first portion and connected to the first rotation axis to rotate between open and closed positions; a second rotation axis; a movable cam mounted on the second rotation axis to rotate between an interference position of the first passage and a free sliding position; a pulley mounted on the first axis; at least one first seat on the first portion and at least one second seat on the second portion at least partially coinciding to couple a first connector to the multifunction device and arranged in an area defined by two straight lines passing through the ends of a segment connecting the first and second rotation axes and perpendicular to the segment.
