Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If static power feeds are used for programmable logic devices, then power distribution is simple and stable, but power efficiency deteriorates for varying workloads
Solution Approach 1:
The patent implements dynamic power feed reconfiguration by allowing the system to switch between different power feed configurations based on the configured design and workload requirements. The board management controller dynamically selects appropriate power feeds and adjusts voltage regulator settings in real-time, transforming the static power distribution system into a dynamic one that adapts to changing operational conditions.
Solution Approach 2:
The system changes power distribution parameters including voltage levels, current allocation, and power feed selection based on the configured design profile. The board management controller modifies these parameters dynamically to match workload requirements, enabling efficient power distribution by adjusting voltage regulator outputs and selecting optimal power feed combinations for different operational states.
2Use of energy by moving object
If multiple voltage regulators and load switches are added for power reconfiguration, then power efficiency improves, but device complexity increases
Solution Approach 1:
The board management controller serves multiple functions: it detects the configured design, determines appropriate power feed settings, controls voltage regulators, and manages load switch configurations. This multi-functional approach consolidates control logic into a single controller that handles various power distribution tasks, reducing overall system complexity despite the presence of multiple power control components.
Solution Approach 2:
The board management controller acts as an intermediary between the configured design requirements and the physical power distribution components. It translates high-level design specifications into specific control signals for voltage regulators and load switches, simplifying the interface between software configuration and hardware power management while enabling efficient power distribution.
3Use of energy by moving object
If power feeds are reconfigured based on configuration profile, then power efficiency improves, but detection and measurement difficulty increases
Solution Approach 1:
The board management controller implements feedback by detecting the configured design profile and using this information to automatically adjust power feed settings. The system continuously monitors the operational state and reconfigures power distribution based on detected configuration changes, creating a closed-loop control system that adapts power delivery to match actual workload requirements while simplifying the detection process through automated feedback mechanisms.
