Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If an integrated monitoring unit is assembled before leaving the factory, then users do not need to assemble the unit and can use it directly, but production costs are relatively high and sterilization processes may cause electronic component failure
Solution Approach 1:
The monitoring unit is divided into separate modules: a first monitoring component (sensor) and a second monitoring component (signal processing module), which are not pre-assembled together. This segmentation allows independent sterilization of each component and reduces production costs while maintaining ease of use through automatic assembly during implantation.
2Ease of operation
If an integrated monitoring unit is assembled before leaving the factory, then users can use it directly without assembly, but sterilization processes may cause electronic component failure leading to low yield
Solution Approach 1:
By separating the monitoring unit into distinct components that can be sterilized independently, the risk of electronic component failure during sterilization is reduced. The first monitoring component and second monitoring component are sterilized separately before automatic assembly during implantation, improving reliability.
3Reliability
If a split monitoring unit is used, then reliability is improved through separate sterilization, but the structure becomes complex and use steps become cumbersome with high learning costs
Solution Approach 1:
The device performs automatic assembly during the implantation process through the driving unit that moves the first and second monitoring components together to establish electrical connectivity. This self-assembly mechanism eliminates the need for manual assembly by users, reducing operational complexity while maintaining the reliability benefits of separate sterilization.
4Reliability
If a split monitoring unit is used, then reliability is improved, but use steps become cumbersome requiring manual assembly by users
Solution Approach 1:
The driving unit automatically moves the first monitoring component and second monitoring component together during implantation to establish electrical connectivity between them. This automatic assembly eliminates the need for manual assembly by users, making the device easy to use while maintaining reliability through separate sterilization of components.

AI summary
A continuous analyte monitoring device includes an outer housing, a cover, a puncture unit, and a monitoring unit. The outer housing has first and second ends opposite to each other in a first direction. The second end has an implantation opening. The cover is detachably connected to the outer housing. A driving unit is movable along the first direction to perform an implantation operation. The puncture unit is movable along a second direction to perform a needle withdrawal operation. The monitoring unit includes a first monitoring component including a sensor and a second monitoring component including a signal processing module. Prior to use, remove the cover and perform a single trigger to enable the driving unit to move along the first direction, thereby partially inserting the sensor into a host and establishing an electrical connectivity between the first and the second monitoring components.
