Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the number of motors or variety of motor types increases, then the motor driving system becomes more capable, but the difficulty of selecting appropriate power supply facilities increases
Solution Approach 1:
The patent replaces manual selection processes with automated computer-based calculation and selection systems. The computer automatically calculates required amplifier quantities and selects appropriate power cables based on motor specifications, eliminating the need for manual analysis and reducing selection complexity as system capability increases.
Solution Approach 2:
The system enables self-service by allowing automatic determination of power supply facility requirements directly from motor specifications. The computer program automatically processes motor data, calculates amplifier needs, and selects appropriate cables without requiring external expert intervention or complex manual procedures.
2Ease of operation
If manual selection of amplifiers and power cables is performed, then flexibility in selection is maintained, but the time and effort required for preparation increases
Solution Approach 1:
The patent implements preliminary action by pre-storing amplifier specifications and power cable data in databases. When motor specifications are input, the system quickly retrieves and matches appropriate components from pre-organized data, dramatically reducing selection time while maintaining flexibility through comprehensive data storage.
Solution Approach 2:
The manual selection process is replaced with automated computer-based calculation and database querying. The system automatically processes motor specifications, calculates amplifier requirements, and retrieves appropriate power cable specifications, reducing preparation time from manual analysis to automated instant retrieval and calculation.
3Reliability
If appropriate power cables are selected without automated assistance, then cost considerations can be manually evaluated, but the overall selection process becomes more time-consuming
Solution Approach 1:
The patent replaces manual evaluation of power supply adequacy and cost considerations with automated computer-based analysis. The system calculates required amplifier quantities, determines appropriate power cable specifications, and evaluates cost-effectiveness automatically, ensuring reliable power supply while reducing selection process time through automated multi-criteria optimization.
