Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If a conventional transformer module (switching DC-DC converter) is used in UPS device, then electrical power conversion is achieved, but the device size and complexity increase
Solution Approach 1:
The patent divides the battery system into N independent battery units, each with its own linear regulator and switch. This segmentation allows each unit to operate independently and simplifies the overall power conversion architecture by replacing the complex transformer module with multiple simple linear regulators.
Solution Approach 2:
The patent replaces the mechanical/electromagnetic transformer module with electronic linear regulators. This substitution eliminates the need for bulky magnetic components and complex switching circuits, achieving power conversion through simpler electronic voltage regulation.
2Power
If a conventional transformer module is used in UPS device, then power conversion is achieved, but the device size increases
Solution Approach 1:
By segmenting the power conversion function into multiple independent battery units with linear regulators, the patent eliminates the need for a large centralized transformer module, thereby reducing the overall device volume.
Solution Approach 2:
Replacing the transformer module with linear regulators removes bulky magnetic components and reduces device size, making the UPS suitable for lightweight and compact electronic products.
3Power
If all battery units supply power simultaneously, then current demand is met, but power loss in linear regulators increases
Solution Approach 1:
The patent dynamically adjusts the number of active battery units based on the current demand. The battery management unit controls switches to enable or disable specific battery units, optimizing the balance between meeting current demand and minimizing power loss in linear regulators.
Solution Approach 2:
The battery management unit monitors the current demand and adjusts the configuration of active battery units accordingly. This feedback mechanism ensures that the system operates efficiently by activating only the necessary number of battery units to meet the load requirements.
