Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the storage system includes more hard disk drives and fans to meet increasing data storage demands, then the storage capacity increases, but the rotational vibration increases causing system instability and performance reduction
Solution Approach 1:
The patent implements dynamic adjustment of fan rotational speeds based on real-time vibration and temperature monitoring. The controller continuously receives vibration information from piezoelectric elements and temperature data, then dynamically adjusts fan speeds to maintain system stability while meeting cooling requirements, resolving the contradiction between increased storage capacity and system stability.
Solution Approach 2:
The system changes operational parameters (fan rotational speed) based on monitored conditions (vibration and temperature). By adjusting the rotational speed parameter dynamically, the system optimizes the balance between cooling performance and vibration control, allowing stable operation with increased storage capacity.
2Object-affected harmful factors
If mechanical designs such as anti-vibration pads are added to suppress rotational vibration of fans, then vibration suppression improves, but device complexity increases
Solution Approach 1:
The patent replaces mechanical vibration suppression methods (anti-vibration pads) with an electronic control system. Piezoelectric material elements detect vibration, and a controller adjusts fan rotational speeds electronically to suppress vibration, eliminating the need for additional mechanical components and reducing device complexity.
Solution Approach 2:
The system implements a feedback control mechanism where piezoelectric elements continuously monitor fan vibration and feed this information to the controller. The controller then adjusts fan rotational speeds in real-time to suppress vibration, providing effective vibration control without adding mechanical complexity.
3Device complexity
If the temperature sensing device is set near the baseboard of hard disk drives, then the device complexity remains low, but the temperature measurement precision decreases providing only approximate temperature information
Solution Approach 1:
The patent extracts temperature measurement functionality from the baseboard location and integrates it directly into the hard disk drive assembly. Temperature sensing elements are positioned near the hard disk drives to capture accurate thermal data, while the controller processes this information to manage fan speeds, maintaining low device complexity while improving measurement precision.
4Device complexity
If fan rotational speeds are adjusted based only on approximate temperature information, then the control system remains simple, but the performance optimization is insufficient due to ignoring vibration information
Solution Approach 1:
The controller performs multiple functions: it monitors both temperature and vibration, processes both types of information, and adjusts fan rotational speeds based on the combined data. This multi-functional approach enables comprehensive performance optimization without significantly increasing control system complexity.
Solution Approach 2:
The system implements comprehensive feedback by monitoring both temperature and vibration parameters simultaneously. The controller receives feedback from both temperature sensors and piezoelectric vibration sensors, then adjusts fan speeds to optimize both thermal management and vibration control, achieving superior performance optimization.
