Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If basic behavior determination units are used to detect user actions, then action information can be generated, but the utility and benefit to users remain insufficient

Engineering Contradiction:

Improveutility of behavior detectionVSAvoidlack of actionable insights

Core Design Contradiction:

Adaptability or versatilityVSLoss of information

Solution Approach 1:

The patent introduces temporal dimension to the traditional spatial behavior mapping. By associating time information with action information and creating time-varying map representations, the system transforms static behavior data into dynamic insights that reveal patterns over time, enabling new applications in navigation and safety assessment

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

Solution Approach 2:

The patent creates an intermediary layer between raw sensor data and practical applications. The map representation processing unit acts as a mediator that synthesizes action information with spatial and temporal dimensions to produce actionable map representations, which then serve as input for navigation systems and safety assessments

Inventive Principle:

Principle #24Intermediary (Mediator)

2Loss of information

If action information is mapped without considering time information, then map representation is simple, but the ability to provide actionable insights is reduced

Engineering Contradiction:

Improvetime-related actionable insightsVSAvoidmap representation processing complexity

Core Design Contradiction:

Loss of informationVSDevice complexity

Solution Approach 1:

The patent segments the map representation into multiple time-varying layers, where each layer represents the spatial distribution of actions at a specific time or time period. This segmentation allows the system to process and interpret temporal patterns separately while maintaining overall map structure, reducing computational complexity

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent transforms the static map representation into a dynamic system that updates and evolves over time. The map representation processing unit dynamically adjusts the map based on time-varying action information, enabling the system to adapt to changing behaviors and provide current, actionable insights

Inventive Principle:

Principle #15Dynamics
