Solution Overview
Problem
Existing medical devices for transcutaneous biosensor insertion face challenges in safe and automatic placement, particularly in reusing components to reduce waste and costs, while ensuring effective and efficient monitoring of biological parameters.
Innovation Solution
A resposable biosensor assembly comprising a reusable sensor assembly (RSA) and a disposable sensor assembly (DSA), where the RSA includes a transmitter, microcontroller, and battery, configured to power both the transmitter and analyte sensor, allowing for multiple uses while the DSA is discarded after each use, with features like antimicrobial coatings and inductive coupling for signal transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the entire sensor assembly is discarded after each use, then infection prevention and safety are improved, but waste generation and cost increase
Solution Approach 1:
The sensor assembly is divided into two distinct segments: a reusable sensor assembly (RSA) containing electronic components and a disposable sensor assembly (DSA) containing the biosensor and insertion apparatus. This segmentation allows the RSA to be reused across multiple patients while the DSA is discarded after single use, thereby preventing infection without maximizing waste generation.
Solution Approach 2:
The invention implements a system where the DSA is discarded after each use to maintain sterilization and prevent infection, while the RSA is recovered and reused. The RSA includes components such as the transmitter, microcontroller, and battery that can be sterilized and reused across multiple patients, reducing overall waste and cost.

3Loss of substance
If a reusable sensor assembly is used, then cost and waste are reduced, but sterilization and infection control become more complex
Solution Approach 1:
The sensor assembly is divided into two distinct segments: a reusable sensor assembly (RSA) containing electronic components and a disposable sensor assembly (DSA) containing the biosensor and insertion apparatus. This segmentation allows the RSA to be reused across multiple patients while the DSA is discarded after single use, thereby preventing infection without maximizing waste generation.
Solution Approach 2:
The DSA is designed as a disposable component that is discarded after single use, simplifying the sterilization process for the RSA. By making the DSA disposable, the RSA can be sterilized more effectively and reused across multiple patients without compromising infection control.
4Manufacturing precision
If automatic insertion is implemented, then placement accuracy and safety are improved, but device complexity increases
Solution Approach 1:
The insertion apparatus is designed to be self-contained within the DSA, incorporating the insertion needle, guide tube, and actuation mechanism. The system enables automatic insertion through a simple user action (pressing a button or activating a mechanism) that triggers the pre-assembled insertion apparatus to deliver the biosensor through the skin, achieving placement accuracy without requiring complex external equipment.
