1Productivity
If manual selection method is used to choose amplifiers from many types, then selection accuracy can be maintained, but selection time and complexity increase significantly
Solution Approach 1:
The patent replaces manual mechanical selection processes with an automated computer-based system. The selection device automatically calculates required amplifier capacities, queries a database for suitable models, and presents optimal combinations to users, eliminating time-consuming manual evaluation of multiple amplifier types while maintaining selection accuracy through systematic computational methods.
Solution Approach 2:
The patent introduces a database as an intermediary between amplifier requirements and available products. The database stores structured amplifier model information and serves as a mediator that automatically matches calculated requirements with suitable products, simplifying the selection process by removing the need for users to manually search and compare numerous amplifier specifications.
2Measurement precision
If comprehensive amplifier information is considered for optimal selection, then selection accuracy improves, but information processing complexity increases
Solution Approach 1:
The patent segments the amplifier selection process into distinct computational stages: calculating total required capacity by summing motor ratings, determining amplifier capacity requirements based on overload ratios, and separately querying database information. This segmentation allows comprehensive information processing to be broken down into manageable steps, maintaining precision while reducing overall complexity.
Solution Approach 2:
The patent uses computational algorithms to automatically process comprehensive amplifier information instead of manual analysis. The system calculates required capacities, retrieves multiple amplifier model specifications from the database, and systematically evaluates combinations, enabling precise selection based on complete information without the cognitive burden of manual processing.
3Measurement precision
If amplifier database with detailed specifications is maintained, then selection accuracy improves, but data management complexity increases
Solution Approach 1:
The patent designs the amplifier database with a universal structure that stores multiple models with various specifications in a standardized format. This universal database structure serves multiple functions: storing capacity information, model specifications, and enabling various query types. The standardized structure simplifies data management while maintaining comprehensive information for accurate selection across different amplifier types.
