Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional 2D selection devices (mouse, trackball) are used to orient a plane in 3D representation, then the plane can be moved through orthogonal representations, but the orientation process becomes awkward and time-consuming
Solution Approach 1:
The patent replaces conventional 2D mechanical selection devices (mouse, trackball) with inertial sensors (accelerometers and gyroscopes) that directly detect the physical orientation of the device in 3D space. This substitution eliminates the need for complex coordinate system transformations and multiple selection steps, allowing the plane to be oriented intuitively by simply holding the device at the desired angle.
Solution Approach 2:
The patent transitions from 2D representation selection to 3D physical device orientation. By using accelerometers and gyroscopes to detect the device's spatial orientation in three dimensions, the system directly maps physical orientation to virtual plane orientation, adding a third dimension of control that eliminates the awkwardness of 2D-based 3D manipulation.
2Adaptability or versatility
If orthogonal 2D representations are used to select and move a plane, then the plane position can be controlled in three dimensions, but the plane orientation is limited to two dimensions
Solution Approach 1:
The patent replaces the complex orthogonal coordinate system manipulation with direct inertial sensing. Accelerometers measure linear acceleration along three axes, while gyroscopes measure angular velocity, providing direct 3D orientation data without requiring the user to understand or manually navigate complex coordinate transformations.
Solution Approach 2:
The inertial sensor device serves multiple functions simultaneously: it detects both position and orientation in three dimensions, controls both the location and angle of the cutting plane, and provides intuitive spatial mapping. This multi-functionality eliminates the need for separate controls for position and orientation that are required in conventional orthogonal representation systems.
