Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If traditional pulse generators are used for RF ablation, then the device complexity is low, but the loss of information is high because anatomical information is not provided to the user
Solution Approach 1:
The patent merges the pulse generator with anatomical mapping and visualization capabilities by integrating a touchscreen display that shows anatomical images with electrode position markers. This combination allows the device to simultaneously provide electrical stimulation functions and anatomical information display, resolving the contradiction between maintaining simple device operation and providing comprehensive anatomical information.
Solution Approach 2:
The touchscreen display acts as an intermediary between the pulse generator and the user, translating complex anatomical data and electrode positions into visual representations. This intermediary layer provides anatomical information without requiring complex additional hardware, as the existing display technology serves as the mediator to convey spatial and anatomical relationships.
2Measurement precision
If anatomical images and real-time feedback are added to the user interface, then the measurement precision is improved, but the device complexity increases
Solution Approach 1:
The patent uses a graphical copy or representation of the anatomical space displayed on the touchscreen, where markers represent actual electrode positions. This virtual copy allows precise tracking and visualization of electrode locations without requiring complex physical measurement devices, as the spatial relationships are replicated in the digital display environment.
3Productivity
If real-time anatomical feedback is provided during the procedure, then the productivity is improved through better planning and execution, but the loss of time for data processing increases
Solution Approach 1:
The anatomical mapping and visualization operate continuously throughout the procedure rather than requiring separate setup and processing phases. The touchscreen display continuously updates with electrode positions and anatomical information as the procedure progresses, eliminating interruptions for data processing and maintaining continuous useful action that improves procedural efficiency.
