Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If real patient jaw movement data is processed to simulate corrective interventions, then the accuracy and relevance of rehabilitation planning is improved, but the complexity of the apparatus and data processing requirements increase
Solution Approach 1:
The patent creates a virtual copy of the patient's actual jaw movement trajectory through computer processing. The system acquires real jaw movement data, processes it into digital representations, and uses these copies to simulate various corrective intervention scenarios without physically altering the patient's anatomy, thereby achieving high accuracy while managing complexity through virtual modeling
Solution Approach 2:
The patent introduces a computer system as an intermediary between the physical jaw movement acquisition and the simulation of corrective interventions. This intermediary processes real patient data, generates virtual trajectories, and enables evaluation of treatment effects before actual procedures, reducing the direct complexity of working with real anatomical structures
2Manufacturing precision
If multiple iterations of simulation are performed to achieve optimal rehabilitation outcomes, then the quality of treatment planning is improved, but the time required for treatment preparation increases
Solution Approach 1:
The patent enables preliminary simulation of corrective interventions on virtual copies of patient jaw movements before actual treatment procedures. By pre-processing real patient data into simulatable formats and preparing multiple intervention scenarios in advance, the system allows quality treatment planning to be performed ahead of time, reducing intra-procedural decision-making time
Solution Approach 2:
The patent implements a feedback loop where simulated jaw movement trajectories are evaluated, and the results feed back into further simulation iterations or direct treatment planning. This automated feedback mechanism allows rapid evaluation of multiple scenarios without manual re-analysis, enabling multiple iterations of quality improvement within reduced timeframes
