Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If power converter settings are configured using traditional methods with additional devices, then setup precision can be achieved, but device complexity and cost increase
Solution Approach 1:
The patent uses an external memory medium (copy) to store settings data that replicates the configuration information needed for power converter setup. This copying approach eliminates the need for complex setup devices while maintaining setup precision, as the settings are transferred directly from the memory medium to the power converter without requiring additional configuration equipment.
Solution Approach 2:
The power converter is designed to automatically read and apply settings from the external memory medium without requiring external configuration devices or complex setup procedures. The system performs self-configuration by autonomously processing the settings data, thereby reducing both device complexity and setup effort while maintaining manufacturing precision.
2Productivity
If power converter settings are configured using traditional methods, then operational reliability can be ensured, but setup time increases
Solution Approach 1:
Settings data are pre-configured and stored on the external memory medium before being transferred to the power converter. This preliminary preparation of configuration data enables rapid setup by simply reading the pre-prepared settings, significantly reducing setup time while ensuring operational reliability since the settings are carefully prepared in advance and directly transferred without manual intervention.
3Adaptability or versatility
If power converter settings are configured using traditional methods, then adaptability to different power grids can be achieved, but cost and complexity increase
Solution Approach 1:
The external memory medium serves as a universal configuration source that can store settings for multiple different power grids and system configurations. This universal approach allows the power converter to be adapted to various power grids by simply changing the settings data on the memory medium, eliminating the need for complex configuration devices or procedures while maintaining full adaptability.
4Ease of operation
If power converter settings are configured using traditional methods, then communication with system components can be established, but setup time and complexity increase
Solution Approach 1:
Communication settings and parameters are pre-configured and copied to the external memory medium along with other power converter settings. This allows communication parameters to be automatically transferred to the power converter during the same rapid setup process, eliminating separate communication configuration steps and reducing overall setup time while maintaining ease of operation.
