Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If traditional physical handheld controller interfaces are used, then users can operate with familiar physical input elements, but the system cannot leverage the potential of gesture tracking technology

Engineering Contradiction:

Improvegesture tracking capabilityVSAvoiduser operation difficulty

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The patent creates a virtual copy of the physical controller interface in the VR environment. The virtual input interface replicates the layout and functionality of physical controllers, allowing users to interact with familiar button arrangements and control schemes through hand gestures, thus bridging the gap between physical familiarity and gesture-based operation

Inventive Principle:

Principle #26Copying

Solution Approach 2:

The virtual input interface serves as an intermediary between the user's physical hand gestures and the VR system's command recognition. By mapping hand positions and gestures to virtual controller elements, the system mediates the translation of natural gestures into meaningful input commands without requiring users to learn entirely new interaction paradigms

Inventive Principle:

Principle #24Intermediary (Mediator)

2Adaptability or versatility

If gesture tracking technology is implemented, then the system can enable new interaction methods, but users require education and guidance to master the new ways of interaction

Engineering Contradiction:

Improveinteraction method diversityVSAvoiduser adaptation time

Core Design Contradiction:

Adaptability or versatilityVSLoss of time

Solution Approach 1:

The system pre-configures the virtual input interface with familiar controller layouts before the user begins interacting. By establishing the virtual interface structure in advance with recognizable button arrangements and control schemes, users can transition to gesture-based operation without needing extensive education or guidance on interface layout and interaction patterns

Inventive Principle:

Principle #10Preliminary action

3Adaptability or versatility

If virtual input interface is configured based on hand feature points, then the interface can be customized to user anatomy, but the system complexity increases

Engineering Contradiction:

Improveinterface customizationVSAvoidconfiguration system complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The system adjusts parameters of the virtual input interface based on detected hand feature points, such as scaling the size of virtual buttons and controls to match the user's hand dimensions. By dynamically modifying interface parameters like button size, spacing, and positioning based on measured hand anatomy, the system achieves customization without requiring complex manual configuration procedures

Inventive Principle:

Principle #35Parameter changes
