Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If single-level vibration feedback is provided, then the system complexity is reduced, but the user immersion and experience quality deteriorate

Engineering Contradiction:

Improvefeedback system complexityVSAvoiduser immersion quality

Core Design Contradiction:

Device complexityVSReliability

Solution Approach 1:

The feedback system is segmented into multiple independent vibration motors distributed at different locations on the device. Each motor can be controlled independently to provide differentiated vibration patterns, enabling the system to simulate various physical characteristics without requiring a single complex feedback mechanism.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Different vibration feedback characteristics are applied to different locations on the device based on the interaction context. The system determines which physical object is being interacted with and applies appropriate vibration patterns to specific motors located near the interaction point, creating localized feedback that enhances realism.

Inventive Principle:

Principle #3Local quality

2Reliability

If multi-parameter vibration feedback is provided based on interaction details, then user immersion is improved, but the computational complexity and processing requirements increase

Engineering Contradiction:

Improveuser immersion qualityVSAvoidprocessing complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The system pre-establishes a library of vibration patterns and characteristics corresponding to different virtual object types and interaction scenarios. When an interaction occurs, the system quickly matches the current context to predefined patterns rather than generating feedback from scratch, reducing real-time computational requirements.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system continuously monitors interaction parameters such as relative position, force direction, and number of interacting objects, and uses this feedback to dynamically adjust vibration patterns. This closed-loop approach allows the system to respond appropriately to changing conditions without requiring complex predictive modeling.

Inventive Principle:

Principle #23Feedback
