Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional solenoid or motor operating mechanisms are used, then the automatic transfer switch can perform opening and closing operations, but the structure becomes complicated with numerous components and high precision manufacturing requirements, reducing reliability
Solution Approach 1:
The patent extracts and eliminates the complex mechanical locking and tripping components from traditional operating mechanisms. By using a permanent magnetic actuator with a simplified link rod system, the design removes unnecessary components while maintaining the essential opening and closing functions, thereby reducing structural complexity and improving reliability.
Solution Approach 2:
The patent replaces traditional mechanical operating mechanisms (solenoids or motors with locking/tripping components) with a permanent magnetic actuator system. This substitution eliminates complex mechanical interactions and precision manufacturing requirements, simplifying the overall structure while maintaining operational reliability.
2Device complexity
If existing permanent magnetic operating mechanisms are used to operate two movable contact subsystems separately, then the structure is simplified, but the switches can misoperate and cannot perform manual operations
Solution Approach 1:
The patent designs a universal permanent magnetic actuator system that can perform multiple functions: automatic operation for both movable contact subsystems, manual operation capability, and reliable positioning. The link rod mechanism serves as a multi-functional component that coordinates the operation of both subsystems while allowing manual intervention, eliminating the misoperation issues of separate control systems.
Solution Approach 2:
The patent merges the control of two movable contact subsystems into a unified permanent magnetic actuator system with a common link rod. This integration ensures coordinated operation, prevents misoperation, and maintains the ability to perform manual operations on either subsystem, thereby improving operational reliability without increasing complexity.
3Stability of the object's composition
If traditional mechanical locking and tripping devices are used, then the opening and closing states can be maintained, but the manufacturing precision requirements and component quantity increase
Solution Approach 1:
The permanent magnetic actuator system provides self-service functionality by using magnetic fields to maintain the opening and closing states without requiring additional mechanical locking and tripping devices. The magnetic actuator inherently maintains state stability through its magnetic holding capability, eliminating the need for complex mechanical state-maintenance components and reducing manufacturing complexity.
