Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If optical sensors are used to detect the position and orientation of the display device, then the position can be determined in relation to the image data set, but the freedom of movement is limited to a space restricted by the sensor's receiving lobe
Solution Approach 1:
The patent combines multiple sensing technologies (optical sensors, accelerometers, gyroscopes, magnetometers) into an integrated sensing system within the display device. This fusion of sensors allows the system to determine position and orientation through multiple methods simultaneously, overcoming the limitations of individual sensor types and expanding freedom of movement while maintaining measurement precision.
Solution Approach 2:
The patent introduces a coordinate system transformation mechanism that acts as an intermediary between the physical sensor measurements and the virtual navigation space. By establishing transformable coordinate systems that can be rotated and translated, the system decouples the physical movement constraints from the virtual navigation freedom, allowing unrestricted movement in the virtual space regardless of physical sensor limitations.
2Adaptability or versatility
If the display device is moved to different locations in different rooms, then visualization can be provided in multiple locations, but recalibration and realignment of the display device and optical sensor in relation to the image data set must be performed each time
Solution Approach 1:
The patent performs preliminary coordinate system transformations and establishes reference frame mappings when the device is first set up or when entering a new location. By pre-calculating transformation matrices and storing them for later use, the system eliminates the need for time-consuming recalibration each time the device is moved to a different room, allowing rapid deployment while maintaining accuracy.
Solution Approach 2:
The patent implements dynamic coordinate system transformations that automatically adapt to the device's current position and orientation. The system continuously updates transformation parameters based on sensor data, allowing the display device to maintain accurate navigation and visualization across different locations without manual recalibration, as the coordinate systems dynamically adjust to the new environment.
3Ease of operation
If the computer screen is moved from the original position to a target position, then navigation through the image data set is enabled, but the section plane must be recalculated based on the change in position
Solution Approach 1:
The patent replaces complex manual navigation operations with automated sensor-based position detection and algorithmic section plane calculation. Instead of requiring users to manually adjust and calculate section planes, the system uses integrated sensors to automatically detect screen position and orientation changes, then computationally determines the appropriate section plane through coordinate transformation algorithms, simplifying the user interaction while managing calculation complexity through efficient mathematical models.
