Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional surgical treatments are used for spinal disorders, then implant delivery can be achieved, but the procedures are highly invasive and lack reliable access to the spinal region
Solution Approach 1:
The delivery device is divided into distinct functional segments: a suction source for implant capture, a tubular conduit for protected transport, and an impactor mechanism for precise placement. This segmentation allows each component to perform its function independently while minimizing overall invasiveness.
Solution Approach 2:
The tubular conduit acts as an intermediary protective channel that shields the implant during transport through the body. It provides a controlled pathway that reduces direct contact with surrounding tissues, thereby reducing invasiveness while maintaining reliable access to the spinal region.
2Object-affected harmful factors
If minimally invasive techniques are used, then patient outcomes are enhanced, but precise positioning and delivery of implants becomes difficult
Solution Approach 1:
The traditional mechanical manipulation methods are replaced with a suction-based capture mechanism. The suction source creates negative pressure to securely grasp the implant without requiring complex mechanical grippers or direct manual manipulation, enabling precise control with minimal invasiveness.
Solution Approach 2:
The impactor mechanism utilizes controlled impact force parameters to precisely position the implant at the target spinal site. By adjusting the force and direction of impact, accurate positioning is achieved without requiring highly invasive exposure or complex positioning mechanisms.
3Manufacturing precision
If suction mechanisms are used to capture implants, then delivery precision is improved, but device complexity increases
Solution Approach 1:
The suction source, tubular conduit, and impactor mechanism are merged into a single integrated delivery device. This consolidation reduces the number of separate components and simplifies the overall device structure while maintaining the precision benefits of the suction-based capture and delivery mechanism.
Solution Approach 2:
The tubular conduit serves multiple functions: it protects the implant during transport, provides a guided pathway for precise delivery, and acts as a structural support for the entire device. This multi-functionality reduces the need for additional specialized components, thereby reducing overall device complexity.

Implementation Method 1
The opening of the valve body is disposed for engagement with a valve part that is configured to close the second passageway such that the suction source draws a fluid through the first passageway to draw an implant into engagement with the distal opening
Implementation Method 2
engaging the impact surface such that the implant engaging surface selectively positions the implant at the surgical site
