Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for inspecting, cleaning, and maintaining load-bearing ropes in structures like bridges require manned devices, which are inefficient and unsafe for long rope lengths, and lack effective unmanned solutions for applying liquids for testing, cleaning, and coating.
Innovation Solution
A device with at least three rollers, driven by a motor, allows for unmanned movement along the rope, enabling precise positioning and application of liquids for inspection, cleaning, and coating, using sensors for data recording and transmission, and adjustable contact force to minimize damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manned inspection devices or aerial work platforms are used for rope inspection and maintenance, then the work can be performed with simple equipment, but the safety risks increase and efficiency decreases for long rope lengths
Solution Approach 1:
The inspection device is self-propelled along the rope using driven rollers that contact the rope surface, eliminating the need for external lifting equipment or manual handling. The device autonomously moves between inspection positions and returns to starting points without human intervention during the inspection process.
Solution Approach 2:
The patent replaces manual inspection methods and aerial work platforms with an automated mechanical system that uses sensors (optical, magnetic, ultrasonic) and computer-controlled positioning to perform inspections, substituting human labor with automated mechanical and electronic systems.
2Measurement precision
If the inspection device is equipped with multiple sensors and automated positioning systems for precise data collection, then the measurement precision improves, but the device complexity increases
Solution Approach 1:
The inspection device integrates multiple sensing capabilities (optical cameras, magnetic field sensors, ultrasonic sensors) into a single multi-functional platform that can detect various types of defects using different physical principles, allowing one device to perform multiple inspection functions simultaneously.
Solution Approach 2:
The patent uses intermediate processing systems including signal processing units, data fusion algorithms, and computer-controlled coordination mechanisms that integrate data from multiple sensors and harmonize their outputs into unified defect detection results, managing complexity through systematic intermediary processing layers.
3Productivity
If the device applies liquid to the rope for cleaning or coating purposes, then the maintenance effectiveness improves, but the risk of rope damage increases
Solution Approach 1:
The device controls the application parameters of liquid (flow rate, pressure, temperature) and the mechanical parameters of roller contact (contact force, speed, distribution pattern) to optimize maintenance effectiveness while preventing excessive force or improper application conditions that could damage the rope surface or coating.
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
Enables efficient, precise, and automated inspection and maintenance of long ropes, allowing for reproducible data recording and liquid application with minimal damage, improving safety and reducing manual labor costs.
Implementation Method 1
The device is in contact with the rope through the at least three, preferably four, rollers. This creates a frictional connection between the rollers and the rope.
Implementation Method 2
at least one liquid is applied to the rope at least at times, at least in some areas

AI summary
The inventive method for applying a liquid to a rope, in which a rope is traversed by a device comprising at least three rollers which are frictionally connected to the rope, wherein at least one roller is driven by at least one motor so that the device is movable along the rope, wherein the at least one motor can be controlled such that the device reproducibly moves to predetermined positions on the rope and at least temporarily applies at least a liquid to at least partial areas of the rope. The method and the device enable automated and unmanned inspection, cleaning, coating repair, and marking of ropes, for example, of suspension bridges. Thus, for example, a defect in the rope can be specifically targeted and repaired with the device.
