Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for sliding along cables, such as those used in rescue operations and adventure activities, face issues with karabiner and device breakages due to stiff constraints that prevent fitting to cable tilts, leading to unwanted stress and potential failures.
Innovation Solution
A device with a base body and connecting element, where the base body is rotatable with respect to a hub and connecting element, allowing for free rotation and improved fitting to cable tilts, while maintaining safety and preventing disengagement, using a hub with a through opening for the connecting element and pulleys for sliding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the karabiner is fixed to the device body with a stiff constraint, then the device structure is simplified and manufacturing is easier, but the device cannot adapt to cable tilts and generates unwanted stresses leading to breakages
Solution Approach 1:
The patent applies the dynamics principle by transforming the static, fixed connection between the karabiner and device body into a dynamic, rotatable connection. The karabiner is mounted on a rotation axis that allows it to freely rotate and adapt its orientation to match cable tilts, eliminating rigid constraints and the associated stresses that lead to breakages.
Solution Approach 2:
The patent changes the orientation parameter of the karabiner relative to the device body. By allowing the karabiner to rotate independently around a vertical axis, its orientation can dynamically adjust to match the cable tilt angle, while the pulleys maintain their fixed orientation for optimal cable contact.
2Stability of the object's composition
If the karabiner is constrained to remain fixed relative to the device body, then the device structure is more stable, but it cannot follow cable tilts and generates inner stresses
Solution Approach 1:
The patent introduces dynamic adaptability by allowing the karabiner to rotate independently on a vertical axis while the pulleys remain fixed. This dynamic configuration enables the karabiner to follow cable tilts and maintain proper orientation, while the overall device structure remains stable through the fixed pulley-cable contact points.
Solution Approach 2:
The patent segments the device into independent rotational components: the karabiner can rotate independently around a vertical axis, while the pulleys are fixed to the device body. This segmentation allows each component to perform its specific function optimally - the karabiner adapts to tilt while the pulleys maintain stable cable contact.
3Device complexity
If the karabiner is mounted with limited rotation movement, then the device structure is simpler, but the fitting to cable tilt is ineffective
Solution Approach 1:
The patent implements full rotational freedom for the karabiner around a vertical axis, allowing it to adapt to any cable tilt angle. This dynamic rotation capability provides effective fitting to cable tilts without requiring complex mounting mechanisms - simply a rotation axis and bearing system.
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 effectively accommodates cable tilts without generating stresses, enhancing safety and usability, particularly on tilted cables, by allowing independent rotation of the base body and connecting element, thus reducing the risk of breakages and improving maneuverability.
