Insertion Device Transverse Actuation Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing insertion devices require users to apply force directly against their body to puncture tissue, which can be difficult for those with limited mobility and may result in pain and mechanical stress on sensors due to transverse motions during the insertion process.
Innovation Solution
An insertion device with a drive mechanism that converts a transverse or opposite motion of the actuating element into a puncturing motion of the insertion needle, reducing the need for direct force application and minimizing mechanical stress on the body.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If users apply force directly against their body to puncture tissue using simple insertion devices, then the puncturing function is achieved, but it becomes difficult for persons with limited mobility and causes pain and transverse motions
Solution Approach 1:
The actuating element is configured to move in a direction transverse to the puncturing direction, converting a lateral motion into the forward puncturing motion of the insertion needle. This dimensional change allows users to apply force perpendicular to their body rather than directly against it, making the device easier to operate and reducing painful transverse motions during insertion.
2Productivity
If users apply force against their body during insertion, then the puncturing action is performed, but it becomes difficult to hold the insertion device steady and prevents tilting
Solution Approach 1:
By configuring the actuating element to move transversely to the puncturing direction, the device allows users to apply force in a direction perpendicular to the insertion direction. This enables the user's other hand to stabilize the device against the body while the actuating element moves laterally, preventing tilting and ensuring successful insertion.
3Productivity
If transverse motions occur during puncturing, then the insertion needle can be inserted, but the inserted sensor is exposed to mechanical stresses and bending
Solution Approach 1:
The actuating element moves in a direction transverse to the puncturing direction, which causes the insertion needle to advance primarily in the forward direction with minimal transverse motion. This reduces mechanical stress and bending on the inserted sensor, improving sensor integrity and measurement reliability.
4Productivity
If bodily tissue is constantly irritated during insertion, then the puncture is made, but inflammation and rejection responses increase
Solution Approach 1:
By moving the actuating element in a direction transverse to the puncturing direction, the device achieves efficient insertion while minimizing transverse motions of the insertion needle. This reduces irritation to the bodily tissue, thereby decreasing inflammation and rejection responses.
