Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If an external transformer is used for power conversion in the interface controller, then the power conversion function is achieved, but the device complexity and production costs increase
Solution Approach 1:
The patent integrates the power supply circuit directly into the interface controller, merging the previously separate external transformer function with the controller itself. This eliminates the need for separate wiring connections to an external transformer and reduces the number of components that need to be assembled and wired during production.
Solution Approach 2:
The interface controller is designed to perform multiple functions including both control operations and power conversion. The integrated power supply circuit allows the controller to handle both low-voltage logic operations and high-voltage power conversion internally, making the device more versatile and eliminating the need for separate dedicated power conversion components.
2Adaptability or versatility
If an external transformer is used for power conversion, then the power supply function is achieved, but compatibility issues arise between interface controller models and auxiliary transformers
Solution Approach 1:
By integrating the power supply circuit into the interface controller, the patent eliminates the interface between the controller and external transformer. This ensures that all interface controller models use the same internal power conversion design, guaranteeing compatibility across different models without requiring matching with specific external transformer units.
Solution Approach 2:
The interface controller becomes self-sufficient by containing its own power conversion capabilities. Each controller model independently handles its own power conversion needs through the integrated circuit, eliminating the need to match with externally provided transformers and ensuring universal compatibility.
3Volume of moving object
If an external transformer is connected to the interface controller, then the power conversion is achieved, but the overall assembly size increases
Solution Approach 1:
The integration of the power supply circuit into the interface controller consolidates multiple components into a single unit. This eliminates the physical space required for separate external transformers and their associated wiring harnesses, significantly reducing the overall volume of the motor assembly.
