Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional spinal plate with fixed shape is used, then the structure is simple and easy to manufacture, but it cannot accurately fit diverse patient spine shapes leading to incomplete attachment
Solution Approach 1:
The spinal plate is divided into a central body and multiple end bodies that can be independently positioned and locked at different angles. Each end body can be rotated and fixed relative to the central body, allowing the plate to adapt to various spine shapes while maintaining a relatively simple overall structure.
Solution Approach 2:
The spinal plate incorporates rotation devices with locking mechanisms that allow the end bodies to be dynamically adjusted to different angular positions during surgery. Once positioned, the locking mechanism maintains the dynamic configuration, enabling the plate to fit diverse spine shapes while keeping the structure manageable.
2Manufacturing precision
If the spinal plate shape is modified for each patient, then the fit accuracy is improved, but the surgery time increases due to difficulty in accurate modification
Solution Approach 1:
The spinal plate is pre-manufactured with standardized components (central body, end bodies, rotation devices, and locking mechanisms) that can be quickly adjusted during surgery. This preliminary preparation of modular components allows for accurate fitting without requiring time-consuming custom modifications during the surgical procedure.
Solution Approach 2:
The spinal plate allows for adjustment of angular parameters through the rotation devices. By changing the rotational angle parameters of the end bodies relative to the central body, the plate can be precisely fitted to different spine shapes without requiring complex custom manufacturing or extensive surgical modification time.
3Reliability
If the spinal plate uses fixed attachment, then the structure is simple, but it causes detachment and side effects due to inability to accommodate various spine shapes
Solution Approach 1:
The spinal plate is segmented into adjustable components (central body and end bodies) connected through rotation devices with locking mechanisms. This segmentation allows each part to be independently positioned to match the patient's spine anatomy, improving attachment reliability while maintaining reasonable structural complexity through modular design.
Solution Approach 2:
The rotation and locking mechanism provides dynamic adjustability that enhances attachment reliability. The end bodies can be rotated to the optimal angle and then locked in place, ensuring secure attachment that adapts to various spine shapes without requiring overly complex structural modifications.

AI summary
The present invention provides a spinal plate which is used to perform fixation surgery on a spine in orthopedic surgery and neurosurgery. According to the present invention, a rotation device and a locking device may be installed so as to be used by fixing any one or more of longitudinal ends of the plate with being rotated at any angle, thereby allowing a doctor to modify a shape of the spinal plate to the shape desired by the doctor, and to perform the surgery by coping with various spin shapes of patients. In addition, according to the present invention, since the shape of the spinal plate may be rotated at any angle, it is possible to cope with various spin shapes of the patients.
