Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If only the position of the energy application part is considered in planning, then the energy application can be performed as desired, but the sensing capability and monitoring quality deteriorate
Solution Approach 1:
The energy application element is segmented into distinct functional parts: an energy application part for delivering energy and one or more sensing parts for monitoring. This segmentation allows each part to be independently positioned and optimized for its specific function, resolving the contradiction between energy application precision and sensing precision.
Solution Approach 2:
The planning system transitions from considering only the position of the energy application part to incorporating the positions and orientations of both the energy application part and sensing parts in three-dimensional space. This dimensional expansion of the planning parameters enables simultaneous optimization of both energy delivery and sensing functions.
2Reliability
If the arrangement of energy application element is optimized for energy delivery, then energy application quality improves, but comprehensive monitoring coverage deteriorates
Solution Approach 1:
The energy application element is designed with multi-functionality, incorporating both energy delivery capability and sensing capability within a single integrated device. This allows the element to simultaneously perform energy application and monitoring functions, eliminating the trade-off between reliability of energy delivery and completeness of monitoring information.
Solution Approach 2:
The sensing parts provide real-time feedback on the treatment process by monitoring properties such as temperature, tissue characteristics, and ablation zone development. This feedback mechanism ensures comprehensive monitoring coverage while maintaining reliable energy application, as the sensing data can be used to adjust and optimize the energy delivery in real-time.

AI summary
The invention relates to an energy application planning apparatus for planning an application of energy to an object (3) like a tumor. An energy application element representation represents an energy application element (5) like an ablation needle including an energy application part for applying energy and a sensing part (7). An arrangement of the energy application element (5) with respect to the object (3) is determined depending on the positions of the energy application part and the sensing part (7) with respect to the energy application element (5) as defined by the energy application element representation and depending on the object representation. The application of energy can therefore not only be planned such that the application of energy is performed as desired, but also such that the object and/or a surrounding of the object are sensible as desired. In this way, the planning procedure can be improved.
