Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If imaging systems use fixed bases with limited gantry movement, then structural stability is maintained, but mobility and flexibility are severely restricted
Solution Approach 1:
The imaging system transitions from a static fixed-base structure to a dynamic mobile platform with motorized wheels and adjustable components. The system can move along the patient's longitudinal axis and rotate around the patient, enabling flexible positioning while maintaining structural integrity through controlled mechanical design.
Solution Approach 2:
The imaging system is divided into separable modules including a mobile base with wheels, a gantry assembly, and an imaging component. This segmentation allows independent optimization of each module's function while reducing overall system complexity through modular architecture.
2Ease of operation
If imaging systems are manually positioned, then ease of operation is improved, but positioning precision and repeatability deteriorate
Solution Approach 1:
The system incorporates sensors that detect the position of the imaging component relative to the patient and provide feedback to the control system. This enables automatic adjustment and verification of positioning, ensuring both ease of operation through automated control and high positioning precision through continuous monitoring and correction.
Solution Approach 2:
Manual mechanical positioning is supplemented or replaced with automated motorized drive systems controlled by software. The motorized wheels and actuators provide precise, programmable movement while sensors and controllers ensure accurate positioning without requiring manual adjustment.
3Productivity
If imaging systems acquire data from limited angles, then acquisition time is reduced, but image quality and three-dimensional reconstruction capability deteriorate
Solution Approach 1:
The imaging system continuously acquires data as it moves along the patient's body and rotates around the patient, rather than taking discrete sequential measurements. This continuous data acquisition maintains high productivity while ensuring complete angular coverage for high-quality three-dimensional reconstruction.
Solution Approach 2:
The system adds rotational movement around the patient as a new dimension of data acquisition, complementing the longitudinal movement along the patient's body. This multi-dimensional approach enables comprehensive imaging from all angles simultaneously, improving image quality without sacrificing acquisition speed.
