Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current durable insertion devices for glucose sensors are complex, prone to wear and damage, require multiple components, and often need disinfection, making them cumbersome for users, while typical side-by-side arrangements of sensors and transmitters face issues with stability, robustness, and comfort.
Innovation Solution
A sensor assembly with a transmitter assembly positioned on top, featuring a sensor base with interfaces for a sensor stack and a mounting base for skin adherence, connected via a rotating motion, and a transmitter cap with electrical contacts, ensuring a stable and robust connection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of stationary object
If a durable insertion device is used for sensor insertion, then the sensor can be inserted multiple times, but the device becomes complex, prone to wear and damage, and requires disinfection
Solution Approach 1:
The patent employs a disposable sensor assembly that includes a single-use insertion device. The sensor assembly is designed to be discarded after one use, eliminating the need for durable, reusable insertion devices that require maintenance, disinfection, and complex cleaning protocols. This resolves the contradiction by sacrificing reusability of the insertion device to reduce complexity and improve reliability.
2Ease of operation
If a side-by-side arrangement of sensor and transmitter is used, then both components are accessible, but stability and robustness of connection are compromised
Solution Approach 1:
The patent positions the transmitter assembly on top of the sensor assembly, creating a stacked or nested configuration rather than a side-by-side arrangement. This vertical stacking improves connection stability and robustness by ensuring close proximity and secure coupling between the sensor and transmitter, while both components remain accessible through the stacked structure.
3Adaptability or versatility
If multiple separate components are used for sensor and transmitter, then each component can be optimized independently, but the overall system becomes complex and less comfortable for users
Solution Approach 1:
The patent merges the sensor assembly and transmitter assembly into an integrated unit where the transmitter is positioned on top of the sensor. This combination reduces the number of separate components that users must manage, improving comfort and ease of use, while maintaining the ability to optimize each component's functionality within the integrated structure.

AI summary
This disclosure generally relates to medical devices that include a sensor transmitter assembly that includes a sensor assembly including a sensor module where a first sensor including a first sensor head having at least one first sensor contact pad is combined with a second sensor including a second sensor head having at least one second sensor contact pad. The sensor transmitter assembly also includes a transmitter assembly positioned on a top of the sensor assembly to form a single unit, the transmitter assembly having at least one transmitter contact disposed on a base of the transmitter assembly, where the first sensor contact pad(s) and the second sensor form a connection path with the transmitter contact(s).
