Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If real-life experiments with human participants are conducted, then actual human interaction data is obtained, but participant availability is limited and personal/environmental variables cannot be fully controlled

Engineering Contradiction:
Improvecontrol of variablesVSAvoidnumber of experiments
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The patent creates simulated human agents that copy and replicate human behavior patterns, personality traits, and interaction dynamics. These digital twins allow researchers to conduct numerous controlled experiments without relying on physical human participants, thereby increasing productivity while maintaining reliability through parameter control.

Inventive Principle:
Principle #26Copying

Solution Approach 2:

The system enables independent adjustment of personality parameters, environmental conditions, and task variables in simulated interactions. This allows researchers to systematically vary parameters across multiple experiments to study their effects on interaction outcomes, achieving both high productivity and reliable control that is impossible with real human subjects.

Inventive Principle:
Principle #35Parameter changes

2Quantity of substance

If more experiments are conducted with real participants, then more data is collected, but participant availability and experimental control are compromised

Engineering Contradiction:
Improveamount of interaction dataVSAvoidexperimental setup and control
Core Design Contradiction:
Quantity of substanceVSEase of operation

Solution Approach 1:

By creating multiple simulated human agents with diverse personality profiles and behavior patterns, the system can generate large volumes of interaction data through automated simulations. This eliminates the need to recruit and coordinate numerous real participants, making the experimental process much easier to operate and scale.

Inventive Principle:
Principle #26Copying

Solution Approach 2:

The simulated agents autonomously engage in interactions based on their programmed personality traits and behavioral models, eliminating the need for human operators to manually conduct each experiment. The system self-generates interaction data through automated simulations, significantly reducing operational complexity.

Inventive Principle:
Principle #25Self-service

3Measurement precision

If real human interactions are observed, then authentic behavior is captured, but it is difficult to isolate and investigate specific personality or environmental variables

Engineering Contradiction:
Improveisolation of variablesVSAvoidflexibility in investigating different variables
Core Design Contradiction:
Measurement precisionVSAdaptability or versatility

Solution Approach 1:

The system allows independent manipulation of personality parameters (e.g., extraversion, neuroticism) and environmental variables (e.g., task type, group size) in simulated interactions. Researchers can systematically vary one parameter at a time while holding others constant, enabling precise measurement of individual variable effects with complete flexibility to investigate any combination of variables.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent decomposes human personality and behavior into discrete, adjustable parameters that can be independently controlled and measured. This segmentation allows researchers to isolate specific personality traits or environmental factors and investigate their individual contributions to interaction outcomes, achieving measurement precision that is impossible in uncontrolled real-world settings.

Inventive Principle:
Principle #1Segmentation
