Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If conventional techniques are used to determine robot actions based on user reactions, then the robot can execute basic actions, but the robot cannot effectively respond to user emotions and behaviors

Engineering Contradiction:

Improverobot's ability to respond to user emotionsVSAvoideffectiveness of action execution

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The patent introduces an emotion determination unit as an intermediary component that bridges user behavior detection and action determination. This unit processes user reactions through predetermined mapping to generate emotion information, which then feeds into the action determination unit. This intermediary layer enables the robot to effectively interpret and respond to emotional states while maintaining reliable action execution.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The system segments the action determination process into distinct functional units: an emotion determination unit that specifically handles emotional state analysis, and an action determination unit that uses this emotion information along with action determination models. This segmentation allows each unit to specialize in its function, improving both emotional responsiveness and action reliability.

Inventive Principle:

Principle #1Segmentation

2Measurement precision

If the robot uses predetermined mapping for emotion determination, then emotion recognition accuracy improves, but system complexity increases

Engineering Contradiction:

Improveemotion recognition accuracyVSAvoidsystem structure complexity

Core Design Contradiction:

Measurement precisionVSDevice complexity

Solution Approach 1:

The patent applies preliminary action by establishing predetermined mapping relationships between user behaviors and emotions before actual interaction occurs. This pre-configured mapping table or database allows the emotion determination unit to quickly and accurately translate observed behaviors into emotional states without requiring complex real-time analysis, thereby maintaining high accuracy while controlling system complexity.

Inventive Principle:

Principle #10Preliminary action
