Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a hard needle tube and implantable biosensor are implanted using existing implanter, then the biosensor can be implanted into subcutaneous tissue, but the implanting speed is low and implanting position is inaccurate
Solution Approach 1:
The implanter is designed to be self-operating with automatic ejection and needle withdrawal mechanisms. The elastic generating component automatically propels the slider to eject the needle tube and biosensor, then automatically withdraws the needle tube after implantation, eliminating manual operation delays and improving both speed and precision.
Solution Approach 2:
The elastic generating component is pre-loaded with elastic energy before use. The slider is pre-positioned to engage with the needle tube and biosensor. When activated, the pre-stored elastic force immediately drives the ejection process, achieving rapid and accurate implantation without manual intervention during the critical ejection phase.
2Ease of operation
If the implanting and withdrawing time is long during implantation, then the user has tingling sensation and pain is increased, but rapid ejection and withdrawal mechanism increases device complexity
Solution Approach 1:
The ejection and withdrawal functions are merged into a single automated sequence driven by the elastic generating component. The slider simultaneously controls both the ejection of the needle tube with biosensor and the subsequent withdrawal of the needle tube, reducing overall operation time and complexity compared to separate manual operations.
Solution Approach 2:
The elastic generating component rushes the implantation and withdrawal process through quickly by converting stored elastic energy into rapid linear motion of the slider. This rushes the needle tube and biosensor through the skin in minimal time, significantly reducing the duration of user discomfort and pain.
3Reliability
If the ejection mechanism performs ejection too early due to misoperation, then accidental injury is easy to be caused, but adding safety lock mechanisms increases device complexity
Solution Approach 1:
The elastic generating component includes a safety mechanism that prevents premature ejection by blocking the release of elastic force until proper activation conditions are met. This preliminary anti-action counteracts potential misoperation by ensuring the elastic energy remains locked until the device is correctly positioned and activated through the intended mechanism.
4Productivity
If manual operation is used for ejection and withdrawal, then the structure is simple, but the implanting speed is low and tissue damage occurs
Solution Approach 1:
The manual mechanical operation is replaced with an elastic force-driven mechanical system. The elastic generating component substitutes for manual pushing and pulling actions, providing controlled rapid ejection and automatic needle withdrawal. This mechanical substitution achieves high-speed implantation with minimal tissue damage through precise force control.
