Engineering Contradiction Analysis
1Measurement precision
If conventional software performs ampacity calculations for one conductor at one ambient temperature with one operating condition and one calculation method in a single simulation, then the calculation accuracy is maintained, but the computational time and number of simulations required increases significantly
Solution Approach 1:
The patent merges multiple independent simulation capabilities into a single integrated simulation system. The software simultaneously performs ampacity calculations for multiple conductors (1-100), multiple ambient temperatures (35 different temperatures), multiple operating conditions (Normal, LTE, STE, DAL), and multiple calculation methods (IEEE 738-2006 surface temperature and IEEE 738-2012 average temperature) within one simulation execution, reducing 2800 separate simulations to a single simulation.
Solution Approach 2:
The patent creates a universal simulation system that can handle diverse calculation scenarios simultaneously. The single simulation framework is designed to accommodate varying numbers of conductors, different ambient temperature ranges, multiple operating conditions, and different IEEE standards, making the software adaptable to any combination of parameters without requiring separate simulation configurations.
2Adaptability or versatility
If conventional software simulates ampacity for multiple conductors across multiple ambient temperatures, operating conditions and calculation methods, then comprehensive rating data is obtained, but the system complexity and computational burden increases
Solution Approach 1:
The patent combines multiple simulation frameworks into a unified system that processes all calculation scenarios simultaneously. By merging the capabilities to handle different conductor counts, temperature ranges, operating conditions, and calculation methods into one integrated simulation engine, the system achieves comprehensive coverage while maintaining manageable complexity through unified architecture.
Solution Approach 2:
The patent utilizes parameter changes to manage system complexity. By allowing users to define input parameters such as the number of conductors, ambient temperature range, operating conditions, and calculation methods, the system dynamically adjusts its simulation scope. This parametric approach enables comprehensive rating data generation while keeping the interface and configuration simple and user-friendly.
3Measurement precision
If conventional software requires 2800 separate simulations to generate 2800 ratings for 10 conductors across 35 ambient temperatures, four operating conditions and two calculation methods, then each individual rating is accurately calculated, but the productivity and efficiency decreases
Solution Approach 1:
The patent merges 2800 separate simulation executions into a single simulation that generates all 2800 ratings simultaneously. The system processes multiple conductors, ambient temperatures, operating conditions, and calculation methods in parallel within one simulation run, maintaining the accuracy of individual ratings while achieving a 2800-fold improvement in productivity.
Solution Approach 2:
The patent implements continuous useful action by maintaining an active simulation engine that processes all calculation scenarios without interruption. Rather than executing 2800 discrete simulations with start-stop cycles, the system continuously generates rating data across all parameter combinations in a single uninterrupted simulation execution, maximizing computational efficiency.
