Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of stationary object
If a single cooling fan is provided to cool multiple electrical components, then the housing size can be reduced, but the cooling performance cannot be maintained across multiple installation specifications due to varying heat generation
Solution Approach 1:
The housing is divided into multiple blocks (first block for AC components, second block for DC components) with separate air inlets and airflow paths. Each block has its own cooling air supply, allowing independent airflow control tailored to the specific heat generation characteristics of AC and DC components under different installation specifications.
Solution Approach 2:
The partition structure is made movable or adjustable to dynamically control the airflow distribution between blocks. By changing the partition position or configuration, the system can adapt the cooling performance to match varying heat generation patterns across different installation specifications while using a single cooling fan.
2Adaptability or versatility
If component specifications and arrangement are changed for each market, then cooling performance can be optimized for each installation specification, but productivity decreases
Solution Approach 1:
A single standardized component arrangement and specification set is designed to universally accommodate multiple installation specifications. The adjustable partition structure enables this universal design to adapt its cooling performance across different markets without requiring custom components or reconfiguration, thereby maintaining high productivity while achieving optimal cooling for each specification.
3Productivity
If the uninterruptible power supply system is used under different installation specifications without changing component specifications, then productivity is maintained, but cooling performance varies due to different current flows and heat generation
Solution Approach 1:
Different airflow quantities are supplied to different blocks based on their specific cooling needs. The partition structure enables localized airflow control where AC components and DC components receive appropriate cooling air volumes according to their heat generation characteristics under each installation specification, achieving temperature control without changing component specifications.
