Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a pair of electrodes is located at the periphery of a target biological tissue region with directly facing arrangement, then the device structure is simple, but the electric field coverage is too fixed and small, limiting the intensity of the electric field covering the target biological tissue
Solution Approach 1:
The invention divides the electrode system into multiple electrodes (first electrode and second electrode) arranged at different positions around the target tissue region, rather than using a single pair of directly facing electrodes. This segmentation allows the electric field to cover a larger and more flexible area of the target tissue.
Solution Approach 2:
The invention transitions from a one-dimensional directly facing electrode arrangement to a multi-dimensional spatial distribution of electrodes around the target tissue. By placing electrodes at different positions and orientations, the electric field coverage expands from a fixed vertical direction to a more comprehensive three-dimensional coverage.
2Manufacturing precision
If multiple electrodes surround the target biological tissue region with different electrical signals, then the electric field coverage and intensity are improved, but the device complexity increases
Solution Approach 1:
The invention applies different electrical signals (first electrical signal and second electrical signal) to different electrodes based on their specific positions and the local requirements of the target tissue region. This allows optimization of the electric field intensity and distribution in different areas of the target tissue.
Solution Approach 2:
The invention uses a controllable electrical signal generation device that can dynamically adjust and switch between different electrical signals applied to different electrodes. This dynamic control capability allows flexible optimization of the electric field configuration to match the specific needs of the target tissue region.
