Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In power supply systems with multiple modules, including batteries and circuits, identifying and replacing faulty components without stopping the entire system is challenging, leading to decreased efficiency and difficulty in determining which modules need replacement.
Innovation Solution
A power supply system with a main line, sweep modules, a problem detector, an indicator, and a controller that allows for sequential switching and disconnection of faulty modules, enabling continuous operation while allowing for safe replacement or repair of faulty components without stopping the entire system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the entire power supply device is stopped to replace or repair faulty modules, then the reliability of replacement/repair is improved, but the productivity of the system decreases
Solution Approach 1:
The power supply device is divided into multiple independent battery circuit modules, each with its own switching devices. This segmentation allows individual modules to be disconnected and replaced without affecting the operation of other modules, enabling maintenance without complete system shutdown.
Solution Approach 2:
The control circuit pre-identifies faulty modules by detecting abnormalities in each battery circuit module. Once a faulty module is identified, the system prepares for its replacement by stopping only that specific module while maintaining operation of healthy modules, thus avoiding complete system shutdown.
2Reliability
If all modules are replaced to ensure system reliability, then the reliability of the power supply device is improved, but the loss of time and resources increases
Solution Approach 1:
The control circuit continuously monitors each battery circuit module and provides feedback on their operational status. When a module becomes faulty, the feedback mechanism identifies it specifically, allowing selective replacement of only the defective module rather than replacing all modules preventively.
3Productivity
If the system continues operation with faulty modules, then the productivity is maintained, but the reliability of the system decreases
Solution Approach 1:
The control circuit extracts or isolates faulty battery circuit modules from the operational system by stopping only those specific modules while maintaining operation of healthy modules. This extraction allows the system to continue operating at reduced capacity rather than shutting down completely, balancing productivity with reliability.

AI summary
The present teaching provides a power supply system capable of appropriately performing replacement or repairing of a component of a module where a problem occurs without stopping the entire operation, in a case where the problem occurs in of the module in a plurality of modules. The power supply system includes a plurality of sweep modules, a problem detector, an indicator, and a controller. Each sweep module includes a battery module and an electric power circuit module. The problem detector detects a problem for each sweep module. The indicator indicates a sweep module in which a problem is detected. In a case where a problem is detected in the sweep module (S4: YES), the controller causes the indicator to indicate a failure sweep module in which the problem is detected (S5). The controller disconnects the failure sweep module from a main line, and continues sweep control (S6 through S8).
