Engineering Contradiction Analysis
1Measurement precision
If complex computational simulation software packages are used to achieve accurate structural and functional simulations of medical devices, then measurement precision and reliability are improved, but device complexity and ease of operation deteriorate
Solution Approach 1:
The system divides the complex simulation process into separate functional modules: a user interface module for input, a processing module for computational simulation, and an output module for results. This segmentation allows each module to be optimized independently, reducing overall system complexity while maintaining simulation accuracy.
Solution Approach 2:
The system introduces an intermediary processing layer that translates user-friendly input parameters into complex simulation parameters, performs the computational simulation, and then translates results back into interpretable output. This intermediary layer shields users from complexity while preserving measurement precision.
2Measurement precision
If complex computational simulation software packages are used to achieve accurate simulations, then measurement precision is improved, but ease of operation deteriorates
Solution Approach 1:
The system creates simplified copies or representations of complex simulation parameters through standardized input templates and pre-configured models. Users interact with these simplified copies rather than the underlying complexity, maintaining ease of operation while preserving simulation accuracy through the intermediary processing layer.
Solution Approach 2:
The system automatically transforms user-friendly parameter inputs into the complex parameter sets required for accurate simulation. By handling parameter transformation internally, the system maintains ease of operation for users while ensuring measurement precision is not compromised.
3Measurement precision
If accurate anatomical and physiological boundary conditions are incorporated into simulations, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The system incorporates pre-configured anatomical and physiological models with standardized boundary conditions that can be selected and applied directly. This preliminary preparation eliminates the need for users to manually configure complex anatomical parameters, reducing setup complexity while maintaining measurement precision through accurate pre-established models.
