Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for determining the lifting capacity of cranes are tedious and time-consuming, requiring users to consult multiple tables and diagrams, and do not provide an efficient way to compare capacities across different crane models or configurations, nor do they offer a continuous representation of lifting capacities.
Innovation Solution
A method and apparatus using a computing device to estimate and display lifting capacity as a continuous spectrum based on boom operating conditions, allowing users to input conditions and visualize lifting capacities graphically, with color coding to represent different capacity ranges, enabling interpolation between discrete values and facilitating the selection of suitable cranes for projects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If users consult multiple capacity tables and work range diagrams to determine lifting capacity, then accurate lifting capacity information can be obtained, but the process becomes tedious and time-consuming
Solution Approach 1:
The patent combines multiple separate capacity tables and work range diagrams into a single integrated graphical display that shows lifting capacity as a continuous spectrum. This merging eliminates the need for users to consult multiple separate documents, thereby reducing time while maintaining accurate capacity information through the unified visual representation.
Solution Approach 2:
The patent creates a visual copy or representation of the capacity data in graphical form rather than requiring users to read and interpret multiple tabular documents. The graphical display with color-coded continuous spectrum serves as a visual copy that preserves the accuracy of capacity information while dramatically reducing the time required to obtain and interpret the data.
2Measurement precision
If discrete capacity tables are used to list lifting capacities at various positions, then specific capacity values can be provided, but continuous representation of lifting capacities across different configurations is not achieved
Solution Approach 1:
The patent transforms the static, discrete capacity tables into a dynamic continuous spectrum display. The graphical representation shows lifting capacity as a continuous gradient across different boom heights and radii, allowing users to visualize capacity variations smoothly rather than jumping between discrete table values. This dynamic visualization maintains specific capacity information while adding continuous adaptability.
Solution Approach 2:
The patent adds a visual dimension to the capacity data by representing lifting capacity as a continuous spectrum with color coding across a two-dimensional graph of boom height versus radius. This dimensional transformation allows the data to convey both specific capacity values and continuous variation simultaneously, enhancing versatility while preserving measurement precision.
3Measurement precision
If multiple capacity tables for different configurations are maintained, then accurate capacity data for specific configurations can be provided, but the device complexity and difficulty of comparison increase
Solution Approach 1:
The patent creates a universal graphical display system that can represent lifting capacity for multiple crane configurations within a single unified interface. Instead of requiring separate tables for each configuration, the system provides a multi-functional display that adapts to show capacity spectra for different boom heights, radii, and crane models, thereby reducing complexity while maintaining configuration-specific accuracy.
Solution Approach 2:
The patent merges multiple configuration-specific capacity tables into a single graphical display that can accommodate and compare different crane models and configurations. The unified visual representation allows users to view and compare capacity spectra across configurations in one interface, eliminating the need to manage and switch between multiple separate tables.
4Measurement precision
If traditional capacity tables are used, then discrete capacity points can be determined, but efficient comparison across different product lines and crane models is not enabled
Solution Approach 1:
The patent merges the ability to display precise capacity points with the ability to compare multiple crane models and configurations in a single graphical interface. The continuous spectrum display allows users to see capacity information for different product lines simultaneously, enabling efficient comparison while maintaining accurate capacity data representation.
Solution Approach 2:
The patent adds visual dimensionality to capacity comparison by representing capacities as color-coded continuous spectra rather than discrete numerical values in tables. This dimensional transformation enables users to quickly compare different crane models and configurations visually, dramatically improving comparison efficiency while preserving the precision of capacity point information.
