Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple electricity supplies are connected to provide redundancy, then reliability is improved, but device complexity increases due to multiple AC-DC regulators and power management requirements
Solution Approach 1:
The patent combines multiple AC-DC regulators and electricity supplies into a unified power supply system with centralized control. The controller integrates power threshold determination, power port authority assignment, and load distribution management into a single control mechanism, reducing the complexity of managing multiple independent power paths while maintaining reliability through coordinated operation of all power supplies
Solution Approach 2:
The controller performs multiple functions including determining power thresholds based on power policies, assigning power port authorities, distributing load across power supplies, and monitoring system status. This multi-functional approach consolidates what would otherwise require separate components for each function, reducing overall system complexity while enabling sophisticated power management for improved reliability
2Reliability
If AC-DC regulators are connected to multiple electricity supplies for redundancy, then reliability is improved, but the regulators become under-utilized during normal operation, reducing productivity
Solution Approach 1:
The system dynamically adjusts the operational status of AC-DC regulators based on real-time power policy requirements and system conditions. The controller can activate or deactivate specific regulators according to the determined power threshold and power port authority, allowing regulators to be utilized efficiently during normal operation while maintaining readiness for redundancy when needed, thus resolving the contradiction between reliability and productivity
Solution Approach 2:
The controller changes operational parameters including power thresholds and regulator activation states based on power policies and system conditions. By adjusting these parameters dynamically, the system optimizes regulator utilization during normal operation while preserving redundancy capabilities, preventing both under-utilization and overloading of regulators
3Productivity
If power threshold is increased to provide more power during failures, then productivity is improved, but safety hazards increase due to potential overloading of remaining power supplies
Solution Approach 1:
The controller continuously monitors the operational status of power supplies and AC-DC regulators, and adjusts the power threshold based on feedback from the system state. This feedback mechanism ensures that the power threshold is increased only to the extent that remaining power supplies can safely handle the load, preventing overloading while maximizing power availability during failure conditions, thus resolving the contradiction between productivity and safety
