Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual control of X-ray tube and detector positions is used, then user control flexibility is maintained, but user fatigue increases and imaging time is extended
Solution Approach 1:
The system automatically performs positioning operations without requiring continuous user intervention. The control unit autonomously adjusts the X-ray tube and detector positions based on pre-stored imaging parameters, allowing the system to serve itself in the positioning task while the user maintains overall control flexibility.
Solution Approach 2:
Positioning parameters and movement paths are pre-stored in the control unit before imaging begins. This preliminary preparation of control data enables rapid automatic positioning during imaging, reducing actual imaging time while preserving user flexibility in selecting imaging protocols.
2Measurement precision
If manual positioning of large volume X-ray tube is used, then positioning precision is difficult to achieve, but system complexity is kept simple
Solution Approach 1:
A control unit acts as an intermediary between the user and the X-ray tube positioning system. This intermediary automatically calculates and executes precise positioning commands, achieving high positioning precision without requiring complex manual manipulation. The control unit manages the complexity internally while presenting a simple interface to the user.
Solution Approach 2:
The patent replaces manual mechanical positioning with an automated control system that uses pre-stored positioning data and automatic movement control. This substitution achieves superior positioning precision by eliminating human error and fatigue, while the control software manages the system complexity without requiring additional hardware complexity.
3Measurement precision
If repeated X-ray imaging is performed to achieve accurate positioning, then positioning accuracy is improved, but patient exposure to X-rays increases
Solution Approach 1:
All positioning parameters, movement paths, and alignment data are pre-calculated and stored in the control unit before imaging begins. This preliminary preparation ensures that the X-ray tube and detector are positioned accurately on the first attempt, eliminating the need for repeated imaging attempts and thereby minimizing patient exposure to X-rays.
Solution Approach 2:
The system incorporates feedback mechanisms that verify positioning accuracy automatically. The control unit monitors the positions of the X-ray tube and detector, compares them with the pre-stored target positions, and makes automatic adjustments if needed. This feedback loop ensures accurate positioning without requiring repeated imaging, thus reducing patient radiation exposure.
