Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If multiple power suppliers are used to meet high power requirements, then the power supply capacity is improved, but energy waste increases due to excessive total output power
Solution Approach 1:
The patent implements dynamic voltage adjustment in power suppliers through voltage converters that continuously adapt output voltage based on real-time load requirements and power distribution status. This dynamic control allows the system to optimize power delivery and eliminate excessive energy output, resolving the contradiction between maintaining high power supply capacity and reducing energy waste.
Solution Approach 2:
The patent employs feedback mechanisms where power suppliers monitor their own output power, voltage, and current status, and exchange this information with other power suppliers through a communication network. Based on this feedback, each power supplier adjusts its output dynamically to achieve optimal power distribution, ensuring total output matches load requirements without excessive energy waste.
2Power
If multiple power suppliers operate at high output, then power availability is improved, but system efficiency deteriorates due to power mismatch
Solution Approach 1:
The patent implements a feedback-based power coordination system where each power supplier monitors its own output status and receives information from other power suppliers and the load. This feedback enables real-time optimization of power distribution, allowing multiple power suppliers to operate efficiently without excessive output, thus improving system efficiency while maintaining power availability.
Solution Approach 2:
The patent changes operating parameters (voltage and power output levels) of power suppliers dynamically based on load requirements and system status. By adjusting voltage through voltage converters and modifying output power levels, the system optimizes the operating parameters of multiple power suppliers to achieve both high power availability and improved system efficiency.
3Productivity
If voltage conversion signals are transmitted between all power suppliers, then power distribution optimization is improved, but communication complexity increases
Solution Approach 1:
The patent implements a universal communication protocol and standardized voltage conversion signal format that can be used by all power suppliers regardless of their specific configuration. This universal approach simplifies the communication architecture, allowing power distribution optimization through standardized signals while reducing the overall communication complexity of the system.
