Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the circuit board is provided for an external business operator for optimization, then the oscillation circuit can be optimized, but information leakage about the circuit board occurs
Solution Approach 1:
The patent creates a virtual model (copy) of the circuit board with its electrical characteristics, stray capacitance, and other parameters. This virtual model allows external business operators to perform optimization calculations without accessing the actual physical circuit board, thereby preventing information leakage while still achieving optimization goals.
Solution Approach 2:
The patent introduces a virtual model as an intermediary between the customer's actual circuit board and the external business operator. The virtual model receives optimization requests and returns optimized parameters without exposing sensitive circuit board information, serving as a protective mediator in the optimization process.
2Loss of information
If the circuit board is kept internal for security, then information leakage is prevented, but oscillation circuit optimization becomes difficult
Solution Approach 1:
Instead of keeping the actual circuit board internal, the patent creates a virtual copy that contains all necessary electrical characteristics and parameters for optimization. This copy can be shared externally for optimization purposes while the original remains secure internally.
Solution Approach 2:
The patent extracts only the necessary electrical characteristics and parameters from the actual circuit board to create a virtual model. This extraction allows optimization to be performed externally without exposing or transferring the complete circuit board information, maintaining security while enabling optimization.
3Manufacturing precision
If complete circuit board information is shared for optimization, then optimization accuracy improves, but security risks increase
Solution Approach 1:
The patent creates a complete virtual copy of the circuit board's electrical characteristics, allowing accurate optimization calculations to be performed on this copy without sharing the actual physical board or sensitive manufacturing information. The copy contains all necessary parameters for accurate optimization while maintaining security.
Solution Approach 2:
The patent transforms physical circuit board characteristics into virtual parameters and data representations. This parameter transformation allows complete optimization analysis to be performed on the virtual parameter set without exposing the physical circuit board or sensitive information, reducing security risks while maintaining optimization accuracy.
