Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If redundant hardware devices with backup mechanisms are adopted to achieve high availability, then system reliability is improved, but hardware costs and power consumption increase
Solution Approach 1:
The power distribution board is designed to serve multiple functions: it detects modular types through detecting pins, selects appropriate configurations via microcontroller, provides power distribution through protecting circuits, and controls fan assembly speeds. This multi-functionality eliminates the need for separate backup hardware while maintaining system reliability through software-based redundancy management.
Solution Approach 2:
The system dynamically changes operational parameters based on detected modular types. The microcontroller selects from multiple configurations and adjusts power distribution parameters and fan speeds accordingly. This parameter adaptation allows the system to optimize power consumption while maintaining reliability by matching resource allocation to actual hardware requirements.
2Reliability
If two motherboards are used to implement backup mechanism in conventional server systems, then system reliability is improved, but hardware costs increase
Solution Approach 1:
The patent merges the backup mechanism functionality into the power distribution board itself rather than requiring separate motherboard-level redundancy. The detecting pins, microcontroller, and protecting circuits work together as an integrated solution that provides configuration-based reliability management, reducing the quantity of hardware components needed while maintaining backup capabilities.
Solution Approach 2:
Instead of physically duplicating motherboards for backup, the system uses software-based configuration copying and virtualization. The microcontroller manages multiple configurations that can be activated based on detected modular types, providing redundancy through logical rather than physical duplication of hardware components.
3Use of energy by moving object
If dynamic configuration based on modular type detection is implemented, then power consumption is reduced, but device complexity increases
Solution Approach 1:
The power distribution board performs self-service by automatically detecting modular types through detecting pins and autonomously selecting appropriate configurations via the microcontroller. This self-configuration capability reduces power consumption without requiring complex external management systems, as the board independently adapts to the installed hardware without manual intervention or complex control architecture.
Solution Approach 2:
The system implements feedback mechanisms where detecting pins continuously monitor modular types and provide information to the microcontroller, which then adjusts power distribution and fan speeds accordingly. This closed-loop feedback system enables dynamic power optimization while keeping device complexity manageable through simple, direct detection and control pathways.
4Temperature
If fan speed is adjusted according to configuration, then cooling efficiency is improved, but control complexity increases
Solution Approach 1:
The fan assembly implements local quality control by adjusting fan speeds based on specific configuration requirements and detected modular types. Different fans or fan groups can operate at different speeds tailored to the thermal requirements of specific hardware configurations, optimizing cooling efficiency for each local thermal zone without requiring complex system-wide control mechanisms.
