Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If simulation-based parameter optimization is performed sequentially for numerous control parameters, then parameter optimization can be achieved, but the time required becomes extremely long

Engineering Contradiction:
Improvecontrol parameter optimizationVSAvoidparameter search time
Core Design Contradiction:
Manufacturing precisionVSLoss of time

Solution Approach 1:

The patent divides the parameter optimization process into two segments: simulation-based optimization for initial parameter candidates, and actual machine-based optimization for final refinement. This segmentation allows the system to leverage the speed of simulation while ensuring accuracy on the actual machine, reducing total optimization time.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent performs preliminary parameter optimization through simulation before actual machine operation. By pre-optimizing parameters in the virtual environment, the system narrows down the search space for actual machine trials, significantly reducing the time required for on-machine parameter tuning.

Inventive Principle:
Principle #10Preliminary action

2Ease of operation

If the operation range is limited to a narrower range than simulation candidates, then actual machine operation is constrained, but robustness to environmental disturbances deteriorates

Engineering Contradiction:
Improvemachine operation rangeVSAvoidrobustness to environmental disturbances
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The patent implements a feedback mechanism where actual machine operation results are compared with simulation results, and the facility model is updated accordingly. This feedback loop allows the system to learn from real-world performance and adjust the model to better reflect actual conditions, improving robustness while maintaining ease of operation.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The patent dynamically adjusts the operation range parameters based on the comparison between simulation and actual machine results. By modifying the search range and evaluation criteria according to real-world performance, the system maintains both ease of operation and robustness to environmental variations.

Inventive Principle:
Principle #35Parameter changes

3Adaptability or versatility

If multiple control parameters are adjusted empirically by users, then customization is possible, but the complexity of adjustment steps increases significantly

Engineering Contradiction:
Improveparameter customizationVSAvoidadjustment process complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent enables the system to perform parameter optimization automatically without requiring extensive user intervention. The facility model and optimization algorithm work together to self-adjust parameters based on performance criteria, reducing the complexity of the adjustment process while maintaining adaptability.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent systematically manages multiple parameter changes through automated algorithms rather than manual empirical adjustment. By using structured parameter optimization methods, the system handles complexity internally while presenting a simplified interface to users, maintaining versatility without increasing perceived complexity.

Inventive Principle:
Principle #35Parameter changes
