Innovation Solution
An intelligent protection switch system that combines a non-power/battery controller with a wireless receiving module, allowing remote control of electrical equipment power loops without the need for digital signal transmission, and enabling wireless operation regardless of power supply status.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a prior art controller is used for remote control, then the controller can control the turning on or off of the power loop when powered on, but the controller cannot control the power loop when powered off
Solution Approach 1:
The patent combines a non-power/battery controller with a wireless receiving module into a single integrated control device. The non-power/battery controller handles local control functions without requiring power, while the wireless receiving module enables remote control capabilities. This merging allows the system to maintain control functionality across different power states and eliminates the limitation of prior art controllers that fail when powered off.
2Ease of operation
If manual operation of molded case circuit breaker is used, then the operation is simple, but the safety risk and inconvenience are increased
Solution Approach 1:
The patent introduces an intelligent protection switch system as an intermediary between the user and the electrical circuit. This system includes a non-power/battery controller that can automatically detect circuit conditions (such as overcurrent or leakage) and control the circuit breaker without requiring manual intervention. The wireless receiving module allows remote control capabilities, eliminating the need for direct manual operation of the molded case circuit breaker and reducing safety risks associated with electrical shock.
3Ease of operation
If remote control system is used, then the convenience is improved, but the system complexity and control pipeline requirements are increased
Solution Approach 1:
The non-power/battery controller is designed to operate autonomously without requiring external power supply or complex control pipelines. It can detect circuit conditions and control the circuit breaker independently. The wireless receiving module integrates wireless communication capabilities directly into the control device, eliminating the need for separate control pipelines and reducing overall system complexity while maintaining remote control convenience.

AI summary
An intelligent protection switch system and molded case circuit breaker and socket thereof are provided, and includes: a housing, non-power/battery controller assembled in the housing, and a wireless receiving module. The non-power/battery controller includes: a bracket assembled on the housing; an electromagnetic induction coil and first and second magnetic plates assembled on the bracket; an linkage guide plate assembled in the housing in a pressable state, and kept a distance from the first and second magnetic plates; and a first control circuit. The wireless module is assembled on the electrical equipment, and includes a second control circuit and router. With the above structure, once the linked guide plate is pressed, the first control circuit forms a closed loop, and generates an induced current and sends out an on/off digital signal received through the router and the second control circuit, to control on/off of the power loop of the electrical equipment.
