Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for diagnosing rope lashings in building structures are time-consuming and pose safety risks due to the need for climbers to create additional rigging for diagnostic devices, especially in challenging environments.
Innovation Solution
A diagnostic module with passive sensors and a travelling module equipped with rollers, driven by a drone, that adjusts to rope inclination and diameter, using a ratchet mechanism and encoder for precise measurement, independent of rope diameter and drone speed, to perform diagnostics efficiently and safely.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If climbers are used to create additional rigging for diagnostic devices, then the diagnostic tests can be performed on rope lashings, but the execution becomes time-consuming and safety risks increase
Solution Approach 1:
The patent replaces the mechanical system of climbers creating rigging with an aerial work platform that positions the diagnostic device directly. This substitution eliminates the time-consuming rigging creation process while maintaining safe access to the rope lashing for diagnostics.
Solution Approach 2:
The patent introduces an aerial work platform as an intermediary between the ground and the rope lashing. This intermediary device provides direct positioning capability for the diagnostic device, eliminating the need for climbers to create intermediate rigging structures.
2Ease of operation
If additional rigging is created for diagnostic devices, then diagnostics can be performed, but the complexity of the system increases
Solution Approach 1:
The aerial work platform serves as an intermediary that simplifies the overall system by providing direct positioning capability, thereby reducing the need for additional rigging and lowering system complexity while maintaining ease of operation.
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 allows for rapid and safe testing of rope lashings along their entire length without additional rigging, reducing activation time and enhancing safety by eliminating the need for climbers, while providing accurate results through signal filtration and analysis.
Implementation Method 1
