Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a hand-held gaming device is used to interact with the virtual world, then user interaction with the video game system is enabled, but the interaction is limited primarily to the graphical depiction and rarely influences objects outside the virtual world
Solution Approach 1:
The patent combines the physical model with the controller device to create a unified system where the model becomes part of the interaction interface. The model includes circuitry that communicates with the controller, merging physical object recognition with digital control functionality, enabling interactions that bridge the virtual and physical worlds.
Solution Approach 2:
The controller device is designed to work with multiple different models through a standardized attachment interface. The system can recognize and adapt to various model types (different circuitry configurations), allowing a single controller to perform multiple functions across different AR/VR applications and model configurations.
2Loss of information
If visual sensing devices are used to capture images of the physical scene, then the physical environment can be displayed, but subsequent captured images from different perspectives do not incorporate the user's alterations
Solution Approach 1:
The system uses visual sensors to continuously track the model and its external visual indicators in the physical environment. The captured images and orientation data are fed back to the computing device, which maintains and updates the virtual model representation in real-time, ensuring that alterations persist across different perspectives and captured images.
Solution Approach 2:
The patent replaces traditional mechanical spatial tracking systems with visual-based tracking using cameras and image recognition. The visual sensor captures images of external visual indicators on the model, and computer vision algorithms determine the model's position and orientation, substituting complex mechanical sensors with optical detection methods.
3Adaptability or versatility
If a detachable model is attached to the controller device, then interchangeability and adaptability are improved, but the device requires additional components and attachment mechanisms
Solution Approach 1:
The attachment interface is designed as a universal connector that can accommodate different model types while maintaining a consistent connection mechanism. The standardized interface allows various models with different circuitry to be attached to the same controller, providing multi-functionality without requiring multiple specialized attachment systems.
Solution Approach 2:
The system is divided into separable components: the controller device, the detachable model, and the attachment interface. This segmentation allows the model to be easily exchanged while keeping the controller reusable, reducing overall system complexity by separating the permanent control elements from the interchangeable model elements.
4Measurement precision
If external visual indicators are used on the model, then the virtual model can be aligned with the physical environment, but the model requires additional components
Solution Approach 1:
The patent replaces complex mechanical alignment systems with visual indicators that can be detected by cameras. Instead of using mechanical fiducial markers or physical alignment features, the system uses visual indicators (such as colored patterns or LED lights) that are captured by visual sensors and processed through image recognition algorithms to determine precise position and orientation.
Solution Approach 2:
The external visual indicators can change their visual parameters (such as color, brightness, or pattern) to convey different information about the model's state, position, or orientation. This allows a single simple component to provide multiple functions for alignment and status indication without requiring multiple separate components.
