Solution Overview
Problem
Current diabetes management systems for closed-loop insulin administration face challenges in efficient and pain-minimized insertion of needles and implantable components for glucose sensing and insulin delivery, particularly in ensuring accurate and reliable operation over a semi-extended period.
Innovation Solution
A disease management system with an adhesive layer and an insertion mechanism that activates upon pressure application, using a combination of insertion and retraction springs to deploy and retract needles, along with an implantable component, ensuring secure adhesion and minimizing patient discomfort during insertion and operation for up to 8 days.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual insertion of needles and implantable components is used, then insertion precision can be controlled, but patient discomfort increases and insertion efficiency decreases
Solution Approach 1:
The needle and implantable component are pre-loaded into the insertion mechanism in a ready-to-deploy configuration. When pressure is applied to the adhesive layer, the mechanism automatically executes the insertion action without requiring manual manipulation during the procedure, thereby improving efficiency and reducing discomfort.
Solution Approach 2:
The insertion mechanism is designed to automatically deploy the needle and implantable component through self-actuation by the applied pressure. The system performs the insertion function autonomously once activated, eliminating the need for manual operation and reducing patient discomfort through consistent, controlled delivery.
2Loss of time
If pressure is applied to activate adhesive layer and insertion mechanism simultaneously, then application time is reduced, but risk of accidental activation increases
Solution Approach 1:
The adhesive layer activation and insertion mechanism activation are merged into a single pressure application event. The structural design ensures that both functions respond to the same input (pressure on the top surface), reducing application time while maintaining reliable control through the mechanical coupling of the activation pathway.
3Duration of action of stationary object
If the disease management system is applied for a useful lifespan of 8 days or more, then prolonged monitoring is achieved, but adhesive reliability may deteriorate over time
Solution Approach 1:
The adhesive layer is formulated with specific material parameters (adhesive strength, cohesion, biocompatibility) that maintain effective bonding over the extended wear duration of 8 days or more. The adhesive properties are optimized to resist degradation from bodily fluids, movement, and environmental exposure throughout the intended wear period.

Implementation Method 1
an adhesive layer configured to couple the disease management system to the patient upon application of pressure to the top surface of the disease management system
Implementation Method 2
unlocking an insertion spring lock with the force applied in the direction of the insertion site to cause an insertion spring to expand from a compressed state of the insertion spring
Implementation Method 3
unlocking a retraction spring lock with the force generated from expansion of the insertion spring to cause a retraction spring to expand from a compressed state of the retraction spring

AI summary
One or more insertion mechanisms may be configured to insert and retract one or more needles associated with a component configured to implantable component into the tissue of a patient. For example, a component or implantable component may include a cannula for delivery of medication to a patient or an analyte sensor. An insertion mechanism may be configured to be part of or enclosed within a structure of the Disease Management System. For example, an insertion mechanism may be configured to operate within the structure of the Disease Management System and not require outside components or devices to apply one or more needles or implantable components to the patient.
