Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If an X-ray machine is fixed to the ground in an examination room, then the X-ray beam can be positioned before the region of interest with several degrees of freedom, but the machine cannot be moved away from the patient support table or bed when the radiography system is not necessary, and the stages of placing and moving the patient become more difficult
Solution Approach 1:
The patent applies the dynamics principle by transforming the X-ray machine from a fixed ground-mounted system to a mobile platform that can be dynamically repositioned. The mobile base allows the X-ray machine to move between different positions (examination position near the patient table and storage position away from the patient table), enabling both excellent patient access during procedures and flexible positioning when needed.
2Ease of operation
If mobile X-ray machines are used that can be moved manually, then the machine can be moved away from the patient support table, but the power delivered by the X-ray tube is not sufficient to perform angiography procedures which require excellent image quality
Solution Approach 1:
The patent applies segmentation by separating the mobility function (mobile base with wheels) from the X-ray generation function (powerful X-ray tube). The mobile base provides easy maneuverability, while the X-ray tube maintains sufficient power for high-quality angiography procedures. This segmentation allows each component to be optimized independently for its specific function.
3Ease of operation
If mobile X-ray machines are used, then the machine can be moved, but the diameter of the arm that supports the tube and the detector is not big enough to provide complex angular movements, and rotation speeds are not sufficient to enable high quality 3D image reconstruction
Solution Approach 1:
The patent applies the dimensionality change principle by adding the horizontal movement dimension through the mobile base, complementing the vertical and rotational movements of the existing arm mechanism. This creates a three-dimensional positioning system that enables complex angular movements and high-quality 3D image reconstruction while maintaining mobility.
4Weight of moving object
If the weight of the machine is reduced to half that of an X-ray machine intended for angiography, then the machine is lighter, but it is still very difficult to move because of its large size and its weight (about 300 kg)
Solution Approach 1:
The patent applies dynamics by implementing a mobile base with directional control capabilities that enable precise maneuvering of the 300 kg machine. The system includes directional indicators and controlled movement mechanisms that make handling the heavy machine easy, transforming it from a static difficult-to-move object to a dynamically controllable mobile system.
