Innovation Solution
A puncture guiding needle with a needle guard, needle seat assembly, and springs that allow for automatic implantation of a chip by extending and retracting the needle tube, facilitated by clamping structures and springs that enable the needle to puncture and withdraw automatically.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a scalpel is used to slice skin tissues and implant chips, then the implantation can be performed, but the process is cumbersome and time-consuming
Solution Approach 1:
The puncture guiding needle is designed to perform the implantation operation automatically once activated. The spring mechanism automatically drives the needle tube to extend and puncture the skin, and then retract after delivering the chip, eliminating the need for manual manipulation during the critical puncture and implantation phases. This self-service mechanism directly addresses the contradiction by enabling rapid implantation without requiring complex manual operations.
Solution Approach 2:
The needle tube is designed to be dynamically movable rather than fixed. It can extend automatically through the skin tissue via spring-driven motion and then retract smoothly after delivering the chip. This dynamic capability allows the device to adapt to the tissue environment and complete the implantation process quickly, resolving the contradiction between implantation speed and operational simplicity.
2Productivity
If a puncture guiding needle with automatic mechanism is used, then implantation becomes quick and convenient, but the device structure becomes more complex
Solution Approach 1:
The device merges multiple functions into a single integrated puncture guiding needle structure. The needle tube, chip holder, spring mechanism, and guiding components are combined into one unified device that performs puncture, chip delivery, and retraction in a single operation. This merging approach reduces the number of separate tools needed while achieving automatic implantation, thereby addressing the contradiction between productivity and structural complexity.
Solution Approach 2:
The needle tube is nested within the needle guard, and the chip holder is positioned within the needle tube. The spring mechanism is compactly arranged within the needle guard structure. This nested arrangement allows the device to achieve complex functionality (automatic puncture and retraction) within a compact form factor, reducing overall structural complexity while maintaining high productivity.
3Extent of automation
If the needle tube extends and retracts automatically, then manual operation is reduced, but the clamping and triggering mechanisms become more complex
Solution Approach 1:
The spring mechanism is pre-loaded within the needle guard before use. The clamping structures are pre-positioned to automatically engage and disengage at predetermined points during the puncture and retraction cycles. This preliminary preparation of mechanical components allows the device to achieve high automation levels without requiring complex real-time control mechanisms, thus resolving the contradiction between automation extent and mechanism complexity.
