Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If haptic data is aggregated in a container without device type information, then data transmission is simplified, but haptic effect rendering accuracy deteriorates due to unknown device arrangements

Engineering Contradiction:

Improvedata transmission structureVSAvoidhaptic effect rendering accuracy

Core Design Contradiction:

Device complexityVSManufacturing precision

Solution Approach 1:

The patent applies preliminary action by pre-defining and signaling the spatial distribution of haptic actuators in a determined multidimensional space before haptic effect rendering. The container is structured in advance to include data representing actuator positions, allowing the rendering engine to accurately map virtual haptic effects to physical actuator locations without requiring complex real-time device detection

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent introduces an intermediary mapping structure that connects the virtual haptic effect space with the physical actuator space. This mapping data acts as a mediator, translating abstract haptic effect parameters into specific actuator activation patterns based on predetermined spatial relationships, thereby ensuring accurate rendering without direct device inspection

Inventive Principle:

Principle #24Intermediary (Mediator)

2Adaptability or versatility

If generic haptic rendering is used without device-specific data, then compatibility across different devices is improved, but rendering precision deteriorates due to lack of device arrangement information

Engineering Contradiction:

Improvedevice compatibilityVSAvoidhaptic effect localization accuracy

Core Design Contradiction:

Adaptability or versatilityVSMeasurement precision

Solution Approach 1:

The patent implements universality by designing a container structure and signaling method that can accommodate multiple haptic device types and configurations through a unified data representation framework. The determined multidimensional space and actuator distribution mapping provide a universal interface that works across different device architectures while maintaining precise localization through device-specific spatial parameters

Inventive Principle:

Principle #6Universality (Multi-functionality)
