Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If clinical trials are conducted to evaluate drug safety and efficacy, then reliable drug evaluation data can be obtained, but the process is time-consuming and expensive

Engineering Contradiction:
Improvedrug evaluation data reliabilityVSAvoidevaluation time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The patent creates a virtual copy of the clinical trial system through a simulation apparatus that replicates patient characteristics, disease progression, and treatment responses. This virtual clinical trial allows repeated evaluations without conducting actual human trials, significantly reducing time and cost while maintaining data reliability through comprehensive computational modeling.

Inventive Principle:
Principle #26Copying

Solution Approach 2:

The system changes the fundamental parameters of clinical trial evaluation from physical human subjects to computational models. By adjusting parameters such as patient demographics, disease severity, and treatment protocols within the simulation environment, the system can rapidly evaluate multiple drug candidates under various conditions without the time constraints of real-world trials.

Inventive Principle:
Principle #35Parameter changes

2Reliability

If multiple clinical trials are conducted to ensure comprehensive drug evaluation, then evaluation reliability improves, but evaluation cost increases

Engineering Contradiction:
Improvedrug evaluation reliabilityVSAvoidevaluation resource consumption
Core Design Contradiction:
ReliabilityVSQuantity of substance

Solution Approach 1:

The simulation apparatus creates virtual replicas of clinical trial scenarios that can be repeatedly executed with different parameters. These virtual copies allow comprehensive evaluation of multiple drug candidates and treatment protocols simultaneously, eliminating the need to fund multiple physical clinical trials while maintaining thorough evaluation coverage.

Inventive Principle:
Principle #26Copying

Solution Approach 2:

The simulation system serves multiple evaluation functions simultaneously - it can assess different drug candidates, evaluate various dosing regimens, test combination therapies, and simulate different patient populations all within a single platform. This multi-functionality reduces the total resource consumption compared to conducting separate dedicated trials for each evaluation objective.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Measurement precision

If actual clinical trials are performed to evaluate drug effects on patients, then real patient response data is obtained, but patient safety and ethical concerns arise

Engineering Contradiction:
Improvepatient response measurement accuracyVSAvoidpatient safety risks
Core Design Contradiction:
Measurement precisionVSObject-affected harmful factors

Solution Approach 1:

The system creates virtual patient models that replicate real patient characteristics, disease states, and treatment responses without exposing actual patients to experimental drugs. These virtual copies maintain measurement precision by incorporating comprehensive patient data and physiological models, while eliminating all patient safety risks associated with unproven drug administration.

Inventive Principle:
Principle #26Copying

Solution Approach 2:

The simulation apparatus acts as an intermediary between drug developers and actual patients. Instead of directly testing drugs on human subjects, the system first evaluates potential treatments on virtual patient models, filtering out unsafe or ineffective candidates before any human testing occurs. This intermediary layer preserves measurement accuracy while removing harmful factors.

Inventive Principle:
Principle #24Intermediary (Mediator)
