Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If vibration is used to simulate tactile sensation when touching virtual objects, then the user can feel contact with virtual objects, but the user cannot feel explicit force feedback and immersion is limited
Solution Approach 1:
The patent replaces the traditional vibration-based tactile feedback mechanism with a stress application mechanism. The stress feedback device uses a pressure generator to apply controlled stress to the user's arm, substituting the mechanical vibration system with a more sophisticated stress control system that can provide explicit force feedback while maintaining immersion.
Solution Approach 2:
The patent introduces a stress feedback device as an intermediary between the user and the virtual reality system. This intermediary device includes a pressure generator that applies stress to the user's arm, acting as a mediator to transmit force feedback information from the virtual environment to the user's physical body, thereby enhancing immersion without direct mechanical coupling.
2Reliability
If stress feedback device is worn on user's arm, then force feedback can be applied to enhance immersion, but device complexity increases
Solution Approach 1:
The patent segments the force feedback system into a wearable stress feedback device worn on the user's arm and a separate control system. This segmentation allows the complex control logic to be housed in the main VR system while the wearable device remains relatively simple, consisting primarily of the pressure generator and position sensor integrated into the arm-worn component.
Solution Approach 2:
The stress feedback device worn on the user's arm serves multiple functions: it applies stress to provide force feedback, tracks the position of the arm through integrated position sensors, and communicates with the main control system. This multi-functionality reduces the need for separate devices and simplifies the overall system architecture despite the enhanced capabilities.
3Ease of operation
If position sensor and pressure generator are integrated, then force feedback can be applied according to trigger signal, but manufacturing complexity increases
Solution Approach 1:
The patent integrates the position sensor and pressure generator into a pre-assembled stress feedback device unit before final system integration. This preliminary integration allows for standardized manufacturing of the wearable component, where the sensors and actuators are positioned and connected in advance, simplifying the final assembly process and reducing on-site integration complexity.
