Solution Overview

Problem

Existing infusion pump systems are not adequately resistant to external contaminants such as precipitation, water splashes, and sweat, which can compromise the integrity of sensitive internal components and user safety during normal daily activities.

Innovation Solution

A wearable infusion pump system with a sealed construction that includes a removably attachable pump device and controller device, featuring a water-resistant seal to protect the electrical connection and sensitive components, allowing for safe and reliable operation in various environmental conditions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the infusion pump system uses a removable controller device that connects to the pump device, then the adaptability and ease of operation are improved, but the risk of contaminant migration to electrical connectors increases

Engineering Contradiction:
Improveremovable controller deviceVSAvoidcontaminant migration
Core Design Contradiction:
Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

A water-resistant seal acts as an intermediary barrier between the electrical connectors and the external environment. The seal is positioned at the interface between the pump device and controller device, blocking the migration path of contaminants while allowing electrical signals to pass through the connectors.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

A flexible water-resistant seal membrane is used to create a protective barrier that conforms to the connector interface. This thin film structure effectively blocks contaminant migration while maintaining the removable connection capability between pump device and controller device.

Inventive Principle:
Principle #30Flexible shells and thin films

2Reliability

If the infusion pump system is designed with a sealed construction to resist contaminants, then the reliability is improved, but the device complexity increases

Engineering Contradiction:
Improvecontaminant resistanceVSAvoidsealed construction
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The sealed construction is segmented into modular components: a seal member integrated into the pump device housing and a corresponding seal interface on the controller device. This segmentation allows the sealing function to be added without completely redesigning the entire system architecture.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The water-resistant seal functionality is merged with the existing mechanical interface between pump device and controller device. The seal member is integrated into the housing structure, combining the sealing function with the connection mechanism rather than adding a separate complex sealing system.

Inventive Principle:
Principle #5Merging (Combining)
