Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If VR provides only visual and auditory stimulation, then the training can be simplified and safer, but the completeness of training is reduced because users cannot interact with structures
Solution Approach 1:
The patent replaces traditional mechanical physical contact with haptic feedback technology. The haptic feedback device generates tactile sensations through controlled vibration and force, allowing users to perceive and interact with virtual structures without actual physical contact. This substitution maintains safety while restoring training completeness through realistic tactile interaction.
Solution Approach 2:
The system changes the parameter of interaction from purely sensory (visual/auditory) to multi-sensory by introducing tactile feedback. The haptic feedback device modifies the physical state of the user's hand through vibration frequency and force magnitude, enabling realistic interaction with virtual objects and structures during training.
2Device complexity
If VR uses only audio-visual stimulation, then the system complexity is reduced, but the ability to simulate physical interactions with structures is lost
Solution Approach 1:
The patent substitutes complex mechanical interaction systems with a haptic feedback-based virtual interaction system. Instead of requiring physical structures for training, the system uses virtual structures combined with haptic feedback to simulate physical interactions, reducing overall system complexity while maintaining interaction realism.
Solution Approach 2:
The system creates a copy of physical interaction through haptic feedback. The haptic feedback device reproduces tactile sensations such as texture, temperature, and force, allowing users to perceive virtual structures as if they were real objects, thereby maintaining interaction realism without requiring actual physical structures.
3Manufacturing precision
If XR training data is generated using template data with attribute information, then the training scenario realism is improved, but the data processing complexity increases
Solution Approach 1:
The system performs preliminary processing by converting real-world images into template data with assigned attribute information before generating training scenarios. This pre-processing step extracts essential features and assigns properties to objects, simplifying the subsequent scenario generation process while maintaining high realism in the training scenarios.
Solution Approach 2:
The patent segments the data processing into distinct stages: image acquisition, template data generation with attribute assignment, and training scenario creation. This segmentation allows each stage to be optimized independently, reducing overall processing complexity while maintaining training scenario realism through structured data handling.
