Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a mechanical circuit breaker is used with an external operation handle, then the circuit breaker can be operated from a distance, but the operation becomes unstable and complex
Solution Approach 1:
The patent replaces the mechanical external operation handle system with a wireless communication system. The operation handle transmits signals wirelessly to the circuit breaker body, eliminating the need for mechanical connections (shafts, couplings) while enabling operation from a distance. This substitution reduces mechanical complexity and improves operational stability.
2Ease of operation
If a separate operation tool is provided for remote operation, then the circuit breaker can be operated from outside, but the tool is prone to loss and damage
Solution Approach 1:
The patent merges the operation handle and circuit breaker into a single integrated system through wireless communication. The operation handle becomes a remote control device that communicates with the circuit breaker body via wireless signals, eliminating the need for separate mechanical tools that can be lost or damaged. The system combines the controlling function and the executed function into one unified apparatus.
3Device complexity
If the interface module is integrated into the circuit breaker body, then the structure is compact, but the operational distance is limited
Solution Approach 1:
The patent segments the circuit breaker system into two independent parts: the circuit breaker body and the operation handle. These segments communicate through wireless signals, allowing the operation handle to be positioned at a distance from the circuit breaker body while maintaining functional connectivity. This segmentation enables remote operation without requiring physical integration.
4Reliability
If a mechanical connection method is used for the operation handle, then the connection is stable, but the operation distance is limited
Solution Approach 1:
The patent substitutes the mechanical connection system with an electromagnetic field-based wireless communication system. The operation handle and circuit breaker body communicate through transmitted and received signals in the electromagnetic spectrum, eliminating the need for physical mechanical connections while enabling operation from a greater distance.
