Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If complex interconnectors are used for electrical contact between sensor and control part, then reliable electrical connection is achieved, but device complexity and volume increase
Solution Approach 1:
The patent combines the electrical contact function with the body mount structure by integrating contact pads directly into the body mount substrate. This eliminates the need for separate complex interconnectors while maintaining reliable electrical connection between the sensor and control part through simplified direct contact.
Solution Approach 2:
The patent extracts the electrical contact function from complex interconnector assemblies and implements it through simple contact pads integrated into the body mount. This separation simplifies the overall device structure while preserving the essential electrical connection functionality.
2Object-affected harmful factors
If traditional sealing methods are used for protecting electrical contacts, then protection against humidity is achieved, but manufacturing precision and assembly difficulty increase
Solution Approach 1:
The patent combines the sealing function with the body mount structure by integrating a sealing ring directly into the body mount housing. This integration eliminates the need for separate sealing components and reduces manufacturing precision requirements, as the sealing function is achieved through the molded structure itself rather than through precise assembly of multiple sealing parts.
3Adaptability or versatility
If multiple separate components are used for sensor assembly, then functional requirements are met, but ease of manufacture and assembly decrease
Solution Approach 1:
The patent merges multiple functional components (body mount, electrical contacts, sealing elements, and mounting structures) into a single integrated body mount assembly. This consolidation maintains all necessary functional requirements while dramatically simplifying manufacturing and assembly processes, as fewer separate parts need to be handled and assembled.
Solution Approach 2:
The body mount structure is designed to perform multiple functions simultaneously: providing mechanical support, establishing electrical contacts, providing sealing protection, and enabling sensor attachment. This multi-functionality eliminates the need for separate dedicated components for each function, thereby simplifying the overall assembly.

Implementation Method 1

Data Source
AI summary
A sensor assembly for detecting at least one analyte in a body fluid includes an electrochemical sensor, a body mount that attaches to a body of a user and an inserter that transfers the sensor to the body mount. A first adhesive is attached to one or both of the body mount or the sensor, and the first adhesive attaches the sensor to the body mount. A second adhesive is attached to one or both of the sensor or the inserter and releasably attaches the sensor to the inserter. The assembly has an initial position in which the sensor is attached to the inserter via the second adhesive and a final position in which the sensor is attached to the body mount via the first adhesive. Transferring the sensor from the initial position to the final position releases the sensor from the inserter.
