Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Data centers evolving to managed IT environments with cloud computing require high-density uninterruptible power supplies (UPS) that can provide rapid backup power without traditional cooling means and occupy minimal rack space, addressing the need for reduced backup times and space efficiency.
Innovation Solution
Integration of high-density UPS systems with power distribution units (PDUs) in a single or separate enclosures, utilizing offline UPS topology and minimal cooling, allowing for 30 seconds to 1 minute backup time, and incorporating batteries within IT equipment without additional space, with optional fan-assisted cooling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional UPS systems with cooling means are used, then reliability is improved, but device complexity and space occupation increase
Solution Approach 1:
The patent removes traditional cooling means (fans, heat sinks) from the UPS system, extracting only the essential power conversion functions. The inverter and battery are integrated into a compact unit that operates without active cooling, reducing complexity while maintaining reliability for short-duration backup power.
Solution Approach 2:
The UPS is designed as a disposable or replaceable unit intended for short-duration backup (30 seconds to 2 minutes). By accepting limited operational lifespan and using simple components without cooling systems, the device achieves high density and low cost while providing sufficient reliability for cloud computing failover scenarios.
2Reliability
If traditional UPS systems with cooling means are used, then reliability is improved, but volume occupied increases
Solution Approach 1:
The patent merges the UPS, battery, and inverter into a single integrated power supply unit that fits within standard IT equipment form factors. By combining these functions and eliminating cooling components, the system achieves five times greater density compared to traditional UPS installations while maintaining adequate reliability for cloud computing applications.
Solution Approach 2:
The UPS system is nested within existing IT equipment or rackmount configurations, with the battery and power conversion components arranged in compact, space-efficient configurations. This nesting approach allows the UPS to occupy minimal rack space while providing reliable backup power.
3Reliability
If backup time is extended, then reliability is improved, but volume occupied increases
Solution Approach 1:
The patent optimizes the battery capacity and power conversion efficiency to achieve extended backup duration (up to 2 minutes) within compact volumes. By changing parameters such as battery chemistry, voltage, and current density, the system maximizes energy storage per unit volume while maintaining acceptable backup time for cloud computing failover.
