Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If artificial bone tissue is fabricated during surgery by conventional manual methods, then the surgeon can address the patient's specific condition, but the operation time increases and requires high level of experience
Solution Approach 1:
The system performs preliminary actions by generating 3D images of the patient's bone tissue before surgery, designing the optimal replacement bone tissue model in advance, and fabricating the artificial bone tissue prior to the surgical procedure. This eliminates the need for time-consuming intraoperative fabrication while ensuring high precision through computer-aided design and manufacturing processes.
Solution Approach 2:
The invention replaces manual mechanical fabrication methods with automated computer-guided systems. The 3D imaging data is processed by software to design the replacement bone, and automated machining or 3D printing equipment fabricates the artificial bone tissue with high precision, eliminating the need for surgeons to manually shape bone tissue during surgery.
2Manufacturing precision
If replacement bone tissue is precisely fabricated during surgery, then treatment accuracy improves, but excessive tissue damage occurs due to unnecessary invasion
Solution Approach 1:
The system performs all fabrication steps before surgery, including 3D imaging, design optimization, and manufacturing of the replacement bone tissue. This preliminary preparation eliminates the need for invasive intraoperative bone harvesting and shaping procedures, thereby reducing tissue damage while maintaining high precision through computer-aided design and manufacturing.
Solution Approach 2:
The invention creates a precise digital copy of the patient's bone structure through 3D imaging, then uses this digital model to design and fabricate the replacement bone tissue. This copying approach ensures anatomical precision without requiring manual manipulation of donor bone tissue, thereby reducing tissue damage from harvesting and shaping procedures.
3Reliability
If autotransplantation is performed to obtain replacement bone tissue, then the patient receives compatible bone tissue, but donor site tissue defects occur
Solution Approach 1:
The invention extracts the necessary information for bone tissue fabrication from 3D images of the patient's own bone structure, then uses this data to design and manufacture artificial bone tissue through additive manufacturing or other fabrication processes. This eliminates the need to physically extract bone tissue from donor sites while maintaining compatibility by using patient-specific anatomical data.
Solution Approach 2:
The system replaces the mechanical process of bone tissue harvesting and transplantation with a computational and manufacturing process. 3D imaging data is processed to design custom artificial bone tissue, which is then fabricated using automated manufacturing systems. This substitution eliminates donor site defects while ensuring tissue compatibility through patient-specific design.
4Adaptability or versatility
If heterotropic transplantation is used to obtain replacement bone tissue, then alternative bone sources are available, but ethical or legal problems arise
Solution Approach 1:
The invention extracts anatomical information from the patient's own bone structure through 3D imaging and uses this data to design artificial bone tissue through computational processes. This eliminates the need to source bone tissue from human donors, thereby avoiding ethical and legal issues associated with heterotropic transplantation while maintaining versatility through custom design capabilities.
Solution Approach 2:
The system creates a digital copy of the patient's bone anatomy and uses this information to manufacture artificial bone tissue through additive manufacturing or other fabrication processes. This copying approach provides versatile customization options without requiring human bone tissue donors, thereby eliminating ethical and legal concerns while maintaining adaptability to patient-specific needs.
