Clamping Device Actuating Mechanism for Rope Release
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional clamping devices for climbing, such as those used in via ferratas, are cumbersome to adjust from a clamping position to a release position, leading to slow progression and potential safety hazards due to the complexity of the mechanism required for reattachment at each anchorage, which increases fall distances and reduces climbing efficiency.
Innovation Solution
A clamping device with a twist-and-slide mechanism is enhanced by incorporating two actuating sections that can be moved towards each other using compressive force, allowing for easier adjustment from a clamping position to a release position, utilizing a lever mechanism that can be actuated by the thumb and fingers for intuitive operation, and featuring a prestressing element for automatic return to the clamping position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a complex mechanism is used to move the clamping body from clamping position to release position, then the clamping device can be securely attached and detached, but the adjustment becomes laborious and time-consuming
Solution Approach 1:
The patent changes the operational parameters by introducing a prestressing element that automatically maintains clamping force. This eliminates the need for complex manual adjustment mechanisms while ensuring reliable attachment, as the prestressing element continuously applies force to keep the clamping body in the clamping position without requiring laborious adjustments.
Solution Approach 2:
The clamping device performs self-service through the prestressing element that automatically maintains clamping force and the actuating mechanism that allows easy transition between positions. The system self-regulates the clamping force without requiring complex external control mechanisms, reducing operational effort while maintaining security.
2Reliability
If a complex mechanism is used to adjust the clamping body, then secure clamping is achieved, but the climbing speed decreases due to time-consuming adjustments
Solution Approach 1:
The patent modifies the system parameters by introducing a prestressing element that automatically maintains optimal clamping force. This eliminates time-consuming manual adjustments while ensuring secure clamping, thereby maintaining climbing speed without compromising clamping security.
Solution Approach 2:
The patent extracts the complex adjustment mechanism and replaces it with a simplified actuating system combined with a prestressing element. This removal of unnecessary complexity reduces the time required for position changes while maintaining reliable clamping, thus improving climbing productivity.
3Reliability
If the clamping bodies are constantly pressed against the cable element by a prestressing element, then immediate clamping effect in case of fall is achieved, but the adjustment to release position requires moving against the prestressing force
Solution Approach 1:
The patent segments the force application by introducing an actuating mechanism with two actuating sections that work in conjunction with the prestressing element. The actuating mechanism locally overcomes the prestressing force only when needed for position changes, while the prestressing element maintains constant clamping pressure during normal operation, achieving both immediate clamping effect and easy adjustment.
Solution Approach 2:
The actuating mechanism serves as an intermediary between the operator and the clamping body, mediating the force required to overcome the prestressing element. This intermediary mechanism translates small operator inputs into the necessary force to move the clamping body against the prestressing force, making adjustment easy while maintaining reliable clamping pressure.
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 enhanced clamping device provides improved safety and efficiency by allowing quick and secure attachment and detachment from the cable element, reducing fall distances and enhancing climbing speed while minimizing the risk of unintentional release.
Implementation Method 1
at least one Prestressing element, the prestressing force of which forces the clamping body from a release position into a clamping position
Implementation Method 2
the prestressing force of which forces the clamping body from a release position into a clamping position
Implementation Method 3
the clamping bodies are guided through the wedge-shaped area of the guide track in the radial direction towards the center of the cable in such a way that the guide track is narrowed so that the clamping bodies are pressed against the cable element. This prevents the cable from being pulled further through the clamping device in the opposite direction to the guide direction.
