Solution Overview
Problem
Conventional sensor inserting devices require manual connection of the sensor and signal processor, which can be cumbersome and painful, especially for self-insertion in areas like the abdomen or arms, due to the need for precise operation and visibility challenges.
Innovation Solution
A sensor inserting device with a movement mechanism that automatically positions and connects the sensor and signal processor, using a dwelling member and spring-based mechanism to support the sensor and insertion needle, allowing for easy insertion and connection without manual operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If manual connection of sensor and signal processor is required, then the device structure can be simple, but the operation becomes troublesome and time-consuming
Solution Approach 1:
The sensor inserting device automatically connects the sensor to the signal processor through its own movement mechanism without requiring external manual intervention. The device performs the connection operation by itself, eliminating the need for users to manually connect components after insertion.
Solution Approach 2:
The patent combines the sensor insertion function and the connection function into a single integrated device. The movement mechanism that inserts the sensor also automatically establishes the electrical connection between the sensor and signal processor, merging multiple operations into one unified system.
2Volume of moving object
If manual connection operation is required, then the device can be compact, but the operating time increases
Solution Approach 1:
The movement mechanism continuously performs both the insertion and connection operations in sequence without interruption. The sensor is inserted and connected in a continuous automated process, eliminating the time loss associated with manual disconnection and reconnection steps.
Solution Approach 2:
The device automatically completes the connection operation immediately after insertion without requiring the user to pause for manual connection, thereby reducing the total time required for the procedure while maintaining a compact form factor.
3Device complexity
If manual connection is required, then the device structure remains simple, but patient suffering increases
Solution Approach 1:
The automated movement mechanism eliminates the need for manual manipulation near the insertion site, reducing patient discomfort and pain during the connection process. The device performs all operations automatically, minimizing patient involvement and associated suffering.
4Loss of time
If automatic connection is implemented, then operation time is reduced, but device complexity increases
Solution Approach 1:
The movement mechanism is designed to perform multiple functions: it both inserts the sensor and establishes the electrical connection. This multi-functionality reduces the need for separate dedicated components for each operation, thereby limiting the increase in overall device complexity while achieving automatic connection.
Solution Approach 2:
The patent merges the insertion mechanism and connection mechanism into a single integrated movement mechanism, reducing the total number of components needed for automatic operation compared to having separate independent systems for each function.

AI summary
The sensor inserting device (10) includes a device body (18), a movement mechanism (20) which inserts a detector (14) and an insertion needle (32) into a body of a patient by moving a sensor (12) with the insertion needle (32), and a dwelling member (24) which is arranged on a moving path of the sensor (12) and attached to the sensor (12) by movement of the sensor (12) caused by the movement mechanism (20). The dwelling member (24) is allowed to dwell on the skin of the patient with the sensor (12) and the transmitter (16) connected at a location in which the detector (14) is inserted into the body of the patient.
