Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a patient uses memory or paper sheets to record drug intake, then the method is simple and requires no additional devices, but the reliability of adherence data is low due to human error in remembering or transcribing

Engineering Contradiction:
Improveadherence data reliabilityVSAvoidmonitoring system complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The system enables self-service monitoring where the patient's own actions (opening the package, removing drugs) automatically generate adherence data through sensors, eliminating the need for manual recording while ensuring reliable data capture without human error

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent replaces manual recording methods (paper sheets, human memory) with automated sensor-based detection systems that use movement sensors, light sensors, and communication modules to automatically track and report drug intake adherence

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Reliability

If a tablet box with electronic device is used to monitor drug intake, then adherence verification capability is improved, but the ease of operation deteriorates due to complex programming and setup requirements

Engineering Contradiction:
Improveadherence verification capabilityVSAvoidsetup and programming ease
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The system automatically configures itself by detecting the package structure and drug contents through sensors, eliminating the need for manual programming. The patient simply places drugs in the package and the system autonomously establishes the monitoring protocol

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system performs preliminary detection of the package structure, drug contents, and dosage requirements before monitoring begins, automatically configuring all parameters in advance so that no setup or programming is needed by the patient at the time of use

Inventive Principle:
Principle #10Preliminary action

3Ease of operation

If manual recording methods are used, then no additional devices are required, but the ability to provide accurate adherence data to medical practitioners is lost

Engineering Contradiction:
Improvesimplicity of useVSAvoidadherence information accuracy
Core Design Contradiction:
Ease of operationVSLoss of information

Solution Approach 1:

The system provides automatic feedback to medical practitioners through communication modules that transmit adherence data, ensuring accurate information delivery without requiring the patient to manually report or interpret their own adherence behavior

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The patent replaces manual information transfer (patient reporting to practitioner) with automated electronic communication systems that directly transmit verified adherence data from the monitoring device to medical practitioners

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)
