Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing circuit breakers for low-voltage circuits have fixed display content, which limits their variability and adaptability to different user needs and orientations, and do not allow for easy removal or reconfiguration during maintenance or startup scenarios.
Innovation Solution
A removable display for circuit breakers with input functionality, equipped with an inclination sensor and a second microcontroller for adjusting displayed information based on orientation, allowing for user-friendly reading and separate control of protection and display functions, and featuring a USB interface and power supply for simplified communication and operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed display is integrated into the circuit breaker, then the display functionality is provided, but the adaptability to different user needs and orientations is limited
Solution Approach 1:
The display is separated from the circuit breaker body and made into a removable component. This segmentation allows the display to be independently configured, oriented, and removed without affecting the circuit breaker's protection functionality, thereby improving adaptability while managing complexity.
Solution Approach 2:
The removable display can be used across different circuit breaker models and configurations. It provides universal functionality for displaying protection parameters, measured values, and status information, while adapting to various mounting orientations through its independent design.
2Ease of operation
If the display is fixed and integrated, then the structure is simple, but the ease of removal and reconfiguration during maintenance is poor
Solution Approach 1:
By dividing the circuit breaker into separable components (circuit breaker body and removable display), the display can be easily removed and reconfigured during maintenance operations without requiring disassembly of the entire device, improving ease of operation.
Solution Approach 2:
The display transitions from a static, fixed state to a dynamic, removable state. This allows the display to be adaptively mounted or removed based on operational needs, maintenance requirements, or user preferences, enhancing operational flexibility.
3Adaptability or versatility
If the display content is fixed, then the device complexity is low, but the adaptability to different orientations and user needs is limited
Solution Approach 1:
The display content and orientation are made dynamic rather than fixed. The display can be rotated to different orientations (e.g., 0°, 90°, 180°, 270°) and the content can be adaptively configured to match the mounting position and user needs, improving versatility without significantly increasing control complexity.
Solution Approach 2:
The display parameters (orientation angle, content configuration) can be changed to adapt to different mounting positions and user requirements. This allows the same display hardware to provide optimized viewing experiences in various orientations and configurations.

AI summary
The invention relates to a circuit breaker for a low-voltage circuit having input and output terminals for conductors of the low-voltage circuit. Within the circuit breaker, the low-voltage circuit can be interrupted or closed. The circuit breaker also has a current sensor which determines the level of the electrical current in the low-voltage circuit and is connected to an electronic trigger unit which has a display for displaying information and interrupts the low-voltage circuit if current limit values or current-time limit values are exceeded. The display is designed to be removable.
