Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional machine interfaces are used, then the interface is simple and easy to understand, but the interface is limited and does not effectively utilize user-defined interactions with virtual objects
Solution Approach 1:
The patent transitions from traditional 2D screen-based interfaces to 3D spatial interfaces using gesture recognition. Users interact with virtual objects in three-dimensional space through hand gestures, allowing for more natural and versatile control while maintaining intuitive operation through spatial metaphors and physical gesture mappings.
Solution Approach 2:
The system introduces virtual objects as intermediaries between the user and the machine control system. These virtual objects serve as mediators that translate physical gestures into digital commands, enabling users to interact with complex machine functions through simple, intuitive gestures without directly programming or configuring the underlying systems.
2Measurement precision
If traditional control methods are used, then the control mechanism is simple, but the control capability and precision are limited
Solution Approach 1:
The patent replaces traditional mechanical control interfaces (buttons, switches, dials) with gesture-based control systems. The system uses computer vision and motion sensing technologies to detect and interpret hand gestures, translating physical movements into digital control signals with high precision while eliminating the need for physical control devices.
Solution Approach 2:
The system detects and interprets multiple parameters of gestures including position, orientation, velocity, acceleration, and gesture shape. By analyzing these parameters, the system can distinguish between different gesture types and intent, enabling precise control with a single degree of freedom while maintaining robustness against variations in gesture execution.
3Adaptability or versatility
If complex virtual interaction spaces are created, then the interaction capability is enhanced, but the system complexity increases
Solution Approach 1:
The patent creates a universal virtual interaction framework that can handle multiple types of interactions (selection, manipulation, navigation, control) through a unified gesture recognition system. The same core technology platform supports various application scenarios and machine control functions, reducing overall system complexity through code reuse and standardized interaction patterns.
Solution Approach 2:
The system segments the complex interaction space into discrete virtual objects and interaction zones. Each virtual object can be independently manipulated through specific gestures, and the system processes gestures by identifying which virtual object or zone is being targeted. This segmentation allows complex interactions to be broken down into manageable, intuitive atomic operations.
