Modular UPS Cabinet with Removable Carrier Plates and Detachable Cables
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional standalone uninterruptible power supplies (UPS) are cumbersome to move and maintain due to their weight, volume, and complex module connection requirements, which complicates repairs and increases maintenance time.
Innovation Solution
The design features a cabinet with rails and removably disposed carrier plates, allowing individual extraction and replacement of modules, simplifying maintenance by using detachable cables for electrical connections between modules.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional standalone UPS components (transformers, heatsink, routes, filters, wires) are integrated in a cabinet with docking terminals, then the UPS provides stable power supply function, but the device becomes difficult to move and transport due to weight and volume
Solution Approach 1:
The UPS system is divided into independent modular units (input module, output module, control module) that can be separately manufactured, transported, and assembled. Each module contains its necessary components (transformers, heatsinks, filters) integrated within, allowing the system to maintain full functionality while improving mobility through modular assembly on rails.
2Reliability
If traditional standalone UPS uses fixed module connections with docking terminals, then the system provides stable operation, but maintenance time increases due to step-by-step disassembly requirements
Solution Approach 1:
The system uses detachable cable connections between modular units instead of fixed docking terminals. This allows individual modules to be quickly disconnected and replaced without disassembling the entire system, significantly reducing maintenance time while maintaining system stability through standardized connection interfaces.
Solution Approach 2:
The connection system transitions from static fixed docking terminals to dynamic detachable cable connections. This enables modules to be easily connected and disconnected during maintenance operations, providing operational flexibility without compromising system reliability when properly connected.
3Power
If traditional standalone UPS combines two cabinets for configuration, then the system meets power requirements, but repair difficulty increases for certain parts
Solution Approach 1:
Instead of combining two separate cabinets, the system uses multiple modular units that can be independently accessed and repaired. Each module contains necessary power components, allowing technicians to work on individual modules without accessing the entire system, improving repair accessibility while maintaining required power capacity.
4Adaptability or versatility
If conventional modular UPS uses docking terminals for module connections, then the system achieves modularity, but manufacturing costs increase
Solution Approach 1:
The system achieves modularity through simple detachable cable connections between standardized modules rather than complex docking terminals. This reduces manufacturing costs by using simpler, more common connection components while maintaining the adaptability and versatility of modular configuration.
Solution Approach 2:
The modular design with standardized cable connections allows the same module types to serve multiple functions and configurations. This universality reduces the need for specialized expensive docking terminals while maintaining system adaptability and versatility.

AI summary
A standalone uninterruptible power supply includes a cabinet and a power supply unit. The cabinet has a frame, rails and carrier plates removably disposed on the rails. The power supply unit installed in the frame includes a control module, a power input module, a power output module and cables. The control module is installed in one carrier plate. The power input module and the power output module are electrically connected with the control module and installed in another carrier plate. The cables are detachably connected with the control module, the input module and the power output module.
