Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a medical technology device is positioned on the patient during pre-interventional imaging, then interventional pressure can be applied to simulate deformation during imaging, but the device occupies space in the imaging system and causes image artifacts
Solution Approach 1:
The patent applies a simplified pressure plate instead of the full medical technology device during pre-interventional imaging. The pressure plate replicates the essential function of applying interventional pressure to create deformation, while omitting complex components that cause image artifacts. This copying approach maintains the useful effect (deformation for imaging) while eliminating harmful effects (artifacts from complex device components).
Solution Approach 2:
The patent extracts only the necessary pressure application function from the complex medical technology device, separating it into a dedicated pressure plate component. By taking out the essential function (applying pressure to create deformation) while removing unnecessary components (ultrasonic transducers, coupling media), the system achieves the desired imaging precision without the harmful image artifacts caused by the full device.
2Measurement precision
If a medical technology device is positioned on the patient during pre-interventional imaging, then interventional pressure can be applied to simulate deformation during imaging, but the device occupies space in the imaging system
Solution Approach 1:
The patent extracts only the essential pressure application function from the complex medical technology device, separating it into a dedicated pressure plate component. This extraction reduces the device volume significantly, allowing the pressure plate to fit within the imaging system's space constraints while still providing the necessary interventional pressure for deformation simulation during imaging.
Solution Approach 2:
The pressure plate serves as a simplified copy of the medical technology device's pressure application function. Instead of using the full-size complex device, the patent creates a reduced-scale version that replicates the essential deformation effect while occupying minimal space within the imaging system, thus resolving the contradiction between imaging precision and device space requirements.
3Ease of operation
If algorithmic deformation correction is used to compensate for device-induced deformation, then imaging can proceed without pressure application, but the correction is fault-prone especially for moving organs
Solution Approach 1:
The patent applies interventional pressure during the pre-interventional imaging process itself, rather than relying on post-imaging algorithmic correction. This preliminary action of applying pressure creates the actual deformation condition during image acquisition, allowing the imaging system to capture data under realistic conditions. This approach eliminates the need for fault-prone algorithmic correction while maintaining ease of operation, as the pressure application is directly integrated into the imaging procedure.
4Reliability
If no pre-interventional imaging is carried out to avoid deformation errors, then treatment risk increases and intervention precision is reduced, but carrying out imaging with deformation causes planning errors
Solution Approach 1:
The patent uses a simplified pressure plate to copy the essential pressure application function during pre-interventional imaging. This copy provides the necessary deformation for realistic imaging conditions while being simple enough to avoid the complex artifact problems of the full medical technology device. The result is reliable imaging data that accurately represents the deformation state during intervention, enabling both safe treatment planning and precise intervention execution.
Solution Approach 2:
By extracting only the pressure application function from the complex medical technology device and implementing it through a dedicated pressure plate, the patent enables pre-interventional imaging under realistic deformation conditions. This extraction allows the imaging to capture accurate deformation data for planning while avoiding the harmful artifacts and space constraints of the full device, thus achieving both treatment safety and planning accuracy.
