Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual operation with input equipment is used to adjust three-dimensional image display, then the examiner can precisely control the cross-section position and direction, but the operation time and complexity increase significantly
Solution Approach 1:
The system performs preliminary actions by automatically determining the cross-section position and direction based on probe position detection, rendering preview images, and pre-calculating optimal viewing angles before the examiner makes final adjustments, thereby reducing the time required for manual searching and adjustment while maintaining precision
Solution Approach 2:
The patent replaces manual mechanical operations with input equipment (trackball, joystick) with an automated computer-based system that detects probe position, calculates cross-section parameters, and renders images automatically, substituting the mechanical adjustment process with algorithmic processing to reduce operation time
2Ease of operation
If manual adjustment of cross-section position is performed using two-dimensional image extraction, then the examiner can observe and adjust measurement target area, but the operation becomes more troublesome and less efficient
Solution Approach 1:
The system performs self-service by automatically determining the cross-section position and direction based on detected probe position and orientation, generating preview images, and presenting multiple candidate cross-sections to the examiner, thereby eliminating the need for manual trial-and-adjustment operations and improving both ease of operation and productivity
Solution Approach 2:
The patent introduces an intermediary automated processing system that acts as a mediator between the probe positioning and the final image display, automatically calculating cross-section parameters and generating preview images to guide the examiner's selection, thereby simplifying the interaction and improving operational efficiency
3Reliability
If complex manual operations are required to set display parameters and rotate three-dimensional images, then precise control is achieved, but the operational load on the examiner increases
Solution Approach 1:
The system performs preliminary actions by automatically calculating optimal display parameters, rendering preview images from multiple angles, and pre-determining cross-section orientations based on probe position, thereby reducing the complexity of manual operations while maintaining reliable and accurate display parameter settings
Solution Approach 2:
The patent replaces complex manual operations for setting display parameters and rotating images with automated computer-based calculations and rendering, substituting manual manipulation with algorithmic processing to reduce operational complexity while ensuring accurate and reliable parameter settings
