Miniature Circuit Breaker Button-Driven Visual State Indicator
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing miniature circuit breakers do not intuitively indicate the switching-on or switching-off states when operated using a button mechanism, posing safety risks during electricity consumption.
Innovation Solution
A miniature circuit breaker design that incorporates an indicating apparatus driven by the button mechanism, which shields an indicating hole or wire removal hole to visually indicate the switching-on state, thereby enhancing safety by warning users not to disconnect or connect wires.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a button mechanism is used to switch on/off the circuit breaker, then the device can be miniaturized and operated conveniently, but the switching state cannot be intuitively judged
Solution Approach 1:
The patent uses an indicating apparatus with different colored regions (first region and second region) that rotate to display different colors through an observation window. When the circuit breaker is switched on, the first region faces the observation window; when switched off, the second region faces the window. This color change mechanism provides intuitive visual feedback about the switching state while maintaining compact button mechanism operation.
2Volume of moving object
If the circuit breaker is miniaturized to meet installation needs, then the device size is reduced, but the indication mechanism becomes more difficult to implement
Solution Approach 1:
The patent combines the indication mechanism with the existing button mechanism by using the button's rotational movement to directly drive the indicating apparatus. The same mechanical action that switches the circuit breaker on/off also rotates the indicating component to display the corresponding state. This integration eliminates the need for separate indication mechanisms, reducing overall device complexity while maintaining miniaturization.
Solution Approach 2:
The button mechanism serves dual functions: it both switches the circuit breaker on/off and simultaneously indicates the switching state through the rotating indication apparatus. This multi-functionality reduces the number of separate components needed, allowing the circuit breaker to be miniaturized while still providing clear visual feedback about its state.
