Solution Overview

Problem

Current drug administration devices often fail to confirm successful drug delivery, leading to potential adverse effects due to human error or device malfunction, and lack of real-time monitoring for correct dosing and administration parameters.

Innovation Solution

A method and system that include sensors to measure dispensing and administration parameters, comparing them to acceptable ranges to confirm successful drug delivery, and modify device operation based on these parameters, providing feedback to users through visual, auditory, or tactile means to prevent further unsuccessful administrations.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If real-time monitoring and feedback mechanisms are implemented, then patient safety and administration accuracy are improved, but device complexity increases

Engineering Contradiction:

Improvepatient safetyVSAvoiddevice complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The monitoring system is divided into separate functional modules: sensors for measuring parameters, processors for analyzing data, and feedback mechanisms for user notification. This modular segmentation allows comprehensive monitoring while maintaining manageable device complexity through organized, independent components.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The system performs preliminary checks of administration parameters before drug delivery occurs. By measuring and validating parameters in advance, the system prevents unsafe administrations and ensures accuracy without requiring complex real-time intervention mechanisms during the actual delivery process.

Inventive Principle:

Principle #10Preliminary action

2Manufacturing precision

If multiple parameters are measured and monitored, then administration accuracy is improved, but device complexity and measurement requirements increase

Engineering Contradiction:

Improveadministration accuracyVSAvoiddevice complexity

Core Design Contradiction:

Manufacturing precisionVSDevice complexity

Solution Approach 1:

The drug administration device incorporates multiple sensors that can measure different parameters (flow rate, pressure, temperature, etc.) using similar structural and processing approaches. This multi-functional design allows comprehensive parameter monitoring while reducing overall device complexity through standardized measurement methodologies.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The system continuously measures administration parameters and provides feedback to both the control system and user interface. This feedback loop enables real-time verification of administration accuracy without requiring overly complex measurement systems, as the feedback mechanism guides and validates the monitoring process efficiently.

Inventive Principle:

Principle #23Feedback

3Reliability

If device operation is modified based on measured parameters, then administration safety is improved, but ease of operation decreases

Engineering Contradiction:

Improveadministration safetyVSAvoidease of operation

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The drug administration device autonomously adjusts its operation based on measured parameters without requiring manual intervention from the user. The system automatically modifies delivery rates, pauses administration, or stops delivery based on sensor data, improving safety while maintaining ease of operation through automated decision-making.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The system provides continuous feedback to the user about parameter measurements and operational modifications. This transparency maintains user confidence and ease of operation by clearly communicating what the device is measuring and why it is adjusting its behavior, reducing the perception of complexity despite enhanced safety features.
