Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual or automated scanning methods are used to locate low impedance points, then treatment precision is improved, but treatment time and cost increase significantly
Solution Approach 1:
The electrode configuration automatically identifies and treats low impedance points through its physical structure without requiring external scanning devices or therapist intervention. The virtual electrode pairs self-select optimal treatment locations based on impedance differences, eliminating the need for separate scanning and treatment phases.
Solution Approach 2:
The electrode is divided into multiple segments with different surface areas (large area electrodes vs. small area electrodes) that create virtual electrode pairs. This segmentation allows simultaneous measurement and treatment across multiple potential treatment points, parallelizing what was previously a sequential scanning process.
2Reliability
If skilled therapists perform scanning and treatment procedures, then treatment effectiveness is improved, but operational cost increases
Solution Approach 1:
The system performs both scanning and treatment functions automatically through its electrode configuration without requiring skilled therapist operation. The physical structure of the electrodes with varying surface areas enables self-directed current flow to low impedance points, making professional scanning expertise unnecessary.
3Measurement precision
If concentrated electrical energy is applied to small treatment areas, then treatment precision is improved, but treatment area coverage decreases
Solution Approach 1:
The electrode array contains multiple virtual electrode pairs distributed across a large surface area, with each pair consisting of large and small area electrodes. This segmentation enables simultaneous concentration of energy at multiple discrete points while collectively covering a broad treatment region.
Solution Approach 2:
The invention transitions from treating one location at a time to treating multiple locations simultaneously by utilizing the spatial dimension. The array configuration allows parallel energy delivery to numerous low impedance points across the treatment area, effectively adding a spatial dimension to the treatment capability.
