Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional tactile interface systems are used in immersive computing, then tactile feedback can be provided, but the system complexity and computational load increase significantly

Engineering Contradiction:

Improvetactile feedback capabilityVSAvoidsystem complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent introduces a tactile command manager as an intermediary layer between the immersive computing application and the tactile interface subsystem. This manager handles tactile effect definitions, parameter management, and coordination, thereby reducing the complexity burden on both the application layer and the hardware layer while ensuring reliable tactile feedback delivery.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The system is segmented into distinct functional modules: application layer for tactile effect definition, tactile command manager for coordination and parameter management, and tactile interface subsystem for execution. This segmentation allows each component to focus on specific tasks, reducing overall system complexity while maintaining comprehensive tactile feedback capabilities.

Inventive Principle:

Principle #1Segmentation

2Reliability

If high-fidelity tactile sensations are generated in real-time, then immersive experience is enhanced, but computational load and latency increase

Engineering Contradiction:

Improveimmersive experience qualityVSAvoidlatency

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

Tactile effects are defined and configured in advance during application development or before runtime. The tactile command manager pre-processes tactile effect definitions and prepares command structures, so that during real-time interaction, only parameter updates and trigger signals need to be transmitted, significantly reducing latency while maintaining high-fidelity tactile sensations.

Inventive Principle:

Principle #10Preliminary action

3Adaptability or versatility

If developers need to implement tactile effects from scratch, then customized tactile feedback can be achieved, but development time and complexity increase

Engineering Contradiction:

Improvetactile effect customizationVSAvoiddevelopment ease

Core Design Contradiction:

Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The patent provides a universal tactile effect definition framework that can accommodate various types of tactile effects (vibrations, pulses, patterns, textures) through a unified parameter structure. Developers can create customized tactile feedback by configuring parameters within this framework rather than implementing entire tactile subsystems, thereby achieving high adaptability with reduced development complexity.

Inventive Principle:

Principle #6Universality (Multi-functionality)

4Device complexity

If tactile commands are managed without a dedicated system, then system simplicity is maintained, but tactile feedback precision and reliability decrease

Engineering Contradiction:

Core Design Contradiction:

Device complexityVSMeasurement precision

Solution Approach 1:

The tactile command manager serves as a dedicated intermediary that precisely manages tactile command generation, parameter validation, and transmission timing. It ensures accurate mapping between application-layer tactile effect definitions and hardware-layer execution commands, thereby maintaining tactile feedback precision without requiring complex modifications to the underlying hardware system.
