Integrated Clamping Insert for Rope Safety Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cable tensioning devices for lifeline systems are complex to install, especially in difficult-to-access locations and under unfavorable weather conditions, due to the need for multiple components and precise assembly to prevent rope slippage and ensure adequate cable length, which complicates the process and increases the risk of assembly errors.
Innovation Solution
A simplified cable tensioning device with a one-piece clamping insert that includes pressure ring and clamping jaws, allowing for automatic clamping and reduced component count, along with a lock nut to secure the screw connection, facilitating easier assembly and ensuring the cable is securely held without slipping during installation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple separate components (clamping jaws, pressure ring, threaded counterpart) are used in conventional cable tensioning devices, then the clamping function can be achieved, but the assembly complexity increases and installation becomes more difficult
Solution Approach 1:
The patent combines the clamping jaws and pressure ring into a single integrated clamping insert component. This merging eliminates the need for separate assembly of these parts, reducing assembly complexity while maintaining the clamping function. The integrated design allows the clamping insert to be inserted as one piece into the clamping sleeve, simplifying the installation process.
2Reliability
If multiple components are assembled in conventional devices, then clamping can be achieved, but the installation time and coordination requirements increase
Solution Approach 1:
By integrating the clamping jaws and pressure ring into a single clamping insert, the patent reduces the number of assembly steps required during installation. The clamping insert is inserted as one component and then clamped by the threaded counterpart, eliminating the need to separately assemble multiple small parts, thereby reducing installation time.
3Reliability
If conventional assembly procedures are used with multiple components, then clamping can be achieved, but the risk of assembly errors increases
Solution Approach 1:
The integrated clamping insert design eliminates the need for precise coordination and alignment of multiple separate components during assembly. Since the clamping jaws and pressure ring are pre-assembled as one piece, there is no risk of misalignment or slippage between separate parts, reducing assembly errors.
Solution Approach 2:
The clamping insert is designed with an automatic clamping effect where the clamping jaws are elastically pressed inwards to clamp slightly against the cable without external pressure. This self-clamping feature ensures proper positioning and prevents slippage during assembly, reducing the need for precise manual alignment.
4Reliability
If the cable end must be precisely positioned during assembly, then proper clamping can be achieved, but the assembly process becomes more complicated
Solution Approach 1:
The clamping insert automatically positions itself on the cable through its elastic clamping action. The clamping jaws are elastically pressed inwards to clamp slightly against the cable, creating a self-positioning effect that ensures the cable end is properly positioned without requiring complex measurement or alignment procedures.
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 solution significantly reduces the complexity of assembly, enhances installation safety by eliminating the need for multiple components and precise alignment, and prevents cable slippage, ensuring a secure and reliable clamping mechanism even under tensile loads.
Implementation Method 1
If the threaded piece is now screwed into the clamping sleeve from the opposite end, it exerts pressure on the clamping jaws in the axial direction. Due to the conical shape of the interior of the clamping sleeve, the clamping jaws are consequently pressed from the outside against the cable and clamp it firmly between them.
Implementation Method 2
Due to the one-piece design of the clamping insert, the clamping jaws are held in a defined position around the free passage channel and can be easily elastically pressed inwards from this position at their free ends. This elasticity and the free diameter of the passage can be matched to the diameter of the cable in such a way that the clamping insert clamps itself slightly against the cable
