Crane Monitoring System Using Graphical Load Curve Simulation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing crane systems lack the ability to display current and possible bearing loads in a simple and understandable manner, particularly for intermediate positions, which limits the operator's ability to evaluate and plan crane movements effectively.
Innovation Solution
A crane equipped with monitoring and simulation means that include input and output units, allowing for real-time representation and simulation of bearing load curves, considering multiple degrees of freedom such as telescoping and luffing movements, using graphic representations and calculation units to model and display the current and possible states of the crane.

Engineering Contradiction Analysis
1Loss of information
If bearing load tables are used to display crane operational data, then comprehensive load information is provided, but the evaluation process becomes time-consuming and complex
Solution Approach 1:
The patent creates a graphical copy representation of the bearing load data through curve diagrams, where the actual bearing load curve is visually reproduced alongside reference curves. This graphical copy allows operators to quickly assess load conditions without manually evaluating detailed tabular data, thereby reducing evaluation time while preserving comprehensive information.
Solution Approach 2:
The patent transforms the two-dimensional tabular data into a visual graphical representation with spatial dimensions. By plotting bearing load values on a curve diagram with horizontal and vertical axes representing different load conditions, the system enables intuitive visual assessment of load states, making the information both comprehensive and easily processable at a glance.
2Loss of information
If detailed bearing load tables are displayed for all crane positions, then complete operational data is available, but the display becomes complex and difficult to interpret quickly
Solution Approach 1:
The system creates a simplified graphical copy of the bearing load information through curve diagrams, where complex tabular data is represented as visual curves. The actual bearing load curve is displayed alongside reference curves, providing an intuitive visual copy that is much easier to interpret quickly while maintaining complete operational data through the graphical representation.
Solution Approach 2:
The patent employs different visual representations and color coding in the graphical display to indicate different load conditions and states. By using visual differentiation in the curve diagram, operators can quickly identify critical load conditions and understand the current state without having to parse complex tabular information, thereby improving ease of operation.
3Reliability
If the crane system provides comprehensive monitoring of all degrees of freedom, then complete operational state is known, but the system complexity increases
Solution Approach 1:
The patent merges multiple monitoring functions into a unified graphical display system. By combining the monitoring of different degrees of freedom (telescoping, luffing, swinging movements) into a single integrated curve diagram representation, the system achieves comprehensive operational state monitoring while reducing the perceived complexity through unified visual presentation rather than separate monitoring interfaces.
