Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If conventional wiring method (live and neutral wires) is used to power circuit breaker, then power supply is reliable, but wiring complexity and panel size increase
Solution Approach 1:
The patent replaces the mechanical wiring system (live and neutral wires physically connected to the circuit breaker) with a wireless power transmission system using electromagnetic fields. The transmitter unit in the panel communicates with the circuit breaker through wireless signals, eliminating the need for additional power wiring while maintaining power supply capability.
Solution Approach 2:
The patent introduces a wireless communication intermediary (transmitter unit and receiver unit) between the power source and the circuit breaker. This intermediary enables power and control signals to be transmitted without direct physical wiring, reducing wiring complexity while maintaining system reliability through the established wireless communication protocol.
2Ease of operation
If Electronic Circuit Breaker (ECB) is used instead of MCB, then automatic resetting is achieved, but device size and wiring requirements double
Solution Approach 1:
The circuit breaker in the patent performs multiple functions: it acts as both the protective device and the receiver for wireless power and control signals. By integrating the wireless communication receiver and control electronics into the existing circuit breaker housing, the patent eliminates the need for a separate ECB unit, thereby maintaining compact size while achieving automatic resetting capability.
Solution Approach 2:
The patent merges the functions of the wireless receiver, control unit, and circuit breaker into a single integrated device. This consolidation allows the circuit breaker to receive wireless power commands and perform automatic resetting without requiring a separate ECB unit, thus reducing overall device size and complexity.
