Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional syndesmosis fixation techniques are used, then surgical procedure can be performed, but anatomical alignment accuracy deteriorates due to psychomotor multitasking and lack of patient-specific adaptation
Solution Approach 1:
The system performs preliminary actions by pre-calculating patient-specific centerlines and drill trajectories before surgery, and by providing real-time guidance during the procedure. The image processing and alignment calculations are performed in advance to establish reference frameworks that guide the surgical drilling, eliminating the need for complex intraoperative adjustments and psychomotor multitasking.
Solution Approach 2:
The patent introduces an image processing and computational guidance system as an intermediary between the surgeon and the surgical instruments. This intermediary provides real-time feedback on drill position and alignment, acting as a mediator that translates complex anatomical relationships into simple visual guidance, thereby improving alignment accuracy without increasing surgical complexity.
2Reliability
If conventional fixation methods are used, then surgery can be completed, but malreduction occurs leading to complications such as altered ankle joint mechanics and chronic pain
Solution Approach 1:
The system implements continuous feedback by capturing images during the surgical procedure, processing them to determine drill trajectory and position, and providing real-time guidance to the surgeon. This closed-loop feedback system ensures that the drill remains aligned with the pre-calculated centerlines, preventing malreduction and improving fixation reliability while eliminating complications associated with inaccurate alignment.
Solution Approach 2:
The patent replaces reliance on surgeon skill and manual alignment techniques with an automated image processing and computational guidance system. By substituting mechanical judgment and psychomotor coordination with algorithmic calculations and visual feedback, the system eliminates malreduction errors and their associated complications.
3Measurement precision
If manual alignment techniques are used, then syndesmosis fixation can be performed, but alignment precision deteriorates due to lack of real-time guidance
Solution Approach 1:
The system maintains continuous useful action by continuously capturing images, processing them to determine drill position and trajectory, and providing real-time guidance throughout the surgical procedure. This continuous feedback loop ensures that alignment precision is maintained throughout the entire drilling process, eliminating the need for repeated measurements and adjustments that would otherwise reduce surgical efficiency.
