Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If traditional implants use simple aperture arrangements, then the device complexity is low, but the fixation strength and adaptability to complex bone defects are insufficient
Solution Approach 1:
The implant divides the aperture arrangement into multiple distinct patterns (first pattern with apertures along reference planes, second pattern with apertures offset from reference planes). This segmentation allows selection of appropriate patterns based on specific bone defect characteristics, optimizing fixation strength for each case without requiring a single complex design.
Solution Approach 2:
The system provides dynamic adaptability by offering multiple aperture patterns that can be selected based on the specific bone defect orientation and characteristics. This dynamic selection capability allows the implant to adapt to varying clinical scenarios, improving fixation strength across different defect types without permanently increasing device complexity.
2Adaptability or versatility
If the implant uses a single aperture pattern, then the device complexity is low, but the adaptability to various bone defect orientations is limited
Solution Approach 1:
The implant achieves universality by incorporating multiple aperture patterns (first and second patterns) within a single device design. Each pattern serves different functional requirements based on bone defect orientation, allowing the same implant to universally address various clinical scenarios including superior-inferior and anterior-posterior defects without requiring multiple specialized implants.
Solution Approach 2:
The implant employs asymmetric aperture arrangements where the first pattern aligns apertures with reference planes for certain defect orientations, while the second pattern offsets apertures from reference planes for other orientations. This asymmetric design provides tailored adaptability to different bone defect geometries, enhancing versatility without requiring symmetric simplification.
3Reliability
If peripheral apertures are arranged along reference planes, then the fixation is optimized for certain defect orientations, but the effectiveness for other defect orientations decreases
Solution Approach 1:
The system dynamically adapts fixation reliability to different defect orientations by providing multiple aperture patterns. The first pattern optimizes reliability for defects aligned with reference planes, while the second pattern optimizes reliability for defects at offset orientations. The surgeon selects the appropriate pattern based on preoperative planning, maintaining high reliability across varying clinical scenarios.
Solution Approach 2:
Each aperture pattern provides localized optimization for specific defect orientations. The first pattern with apertures along reference planes provides superior fixation reliability for superior-inferior defects, while the second pattern with offset apertures provides optimized fixation for anterior-posterior defects. This local quality approach ensures high reliability for the specific orientation being treated.
