Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional visual display interfaces are used for surgical navigation, then surgeons can see alignment information, but audible feedback is needed for hands-free workflow guidance
Solution Approach 1:
The system provides audible feedback to the surgeon based on real-time measurement data from the load sensing unit and navigation device. The audio output indicates alignment status and workflow completion, enabling hands-free guidance while maintaining information delivery through auditory channels complementary to visual displays.
2Measurement precision
If quantitative measurement devices are integrated into the surgical workflow, then measurement precision improves, but device complexity increases
Solution Approach 1:
The load sensing unit and navigation device are designed to perform multiple functions: measuring load balance, determining alignment, providing surgical guidance, and delivering feedback. This multi-functionality reduces the need for separate specialized devices while maintaining measurement precision.
Solution Approach 2:
The system uses an intermediary processing architecture where measurement data from the load sensing unit is processed by the navigation device, which then outputs guidance information. This layered approach manages complexity by separating sensing, processing, and output functions while maintaining integrated operation.
3Productivity
If real-time feedback is provided during surgical procedures, then productivity improves, but loss of time for measurement and alignment increases
Solution Approach 1:
The load sensing unit continuously measures load balance and the navigation device continuously tracks alignment throughout the surgical procedure. Real-time feedback is provided without interrupting the surgical workflow, eliminating the need for separate measurement and alignment steps while maintaining continuous monitoring and guidance.
