Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If user directly selects electrode positions based on visual inspection, then the operation is simple and quick, but the positioning accuracy is insufficient and cannot accurately stimulate target points
Solution Approach 1:
The patent introduces a computing device as an intermediary between the user and the electrode placement process. The computing device receives image data, performs simulation calculations, and provides guidance on optimal electrode positions, acting as a mediator that bridges simple user operation with complex positioning requirements without requiring the user to directly perform complex measurements or calculations
Solution Approach 2:
The patent replaces manual visual inspection and physical measurement methods with computer-based image processing and simulation systems. Instead of using traditional mechanical measuring tools or visual estimation, the system uses digital images and computational algorithms to determine precise electrode positions, substituting mechanical and manual processes with automated computational ones
2Manufacturing precision
If electrode positions are selected without simulation, then the process is fast and simple, but the stimulation accuracy and treatment efficacy are reduced
Solution Approach 1:
The patent performs simulation calculations and determines optimal electrode positions before the actual electrode attachment process. By conducting the simulation and analysis in advance, the system prepares the optimal placement方案 beforehand, allowing the actual electrode attachment to proceed quickly and accurately without requiring time-consuming trial and error adjustments during the treatment process
Solution Approach 2:
The system automatically performs image processing, simulation calculations, and optimization without requiring manual intervention for each step. The computing device autonomously analyzes the input images, runs the simulation models, and generates the optimal electrode placement recommendations, making the system self-sufficient and reducing the time burden on users
3Measurement precision
If all stimulation positions are simulated without filtering, then the optimal position can be found, but unnecessary calculations increase processing time and computational load
Solution Approach 1:
The patent segments the simulation process into two distinct stages: a filtering stage that quickly eliminates obviously unsuitable positions based on preset conditions, and a simulation stage that performs detailed calculations only on the remaining candidate positions. This segmentation allows the system to handle different types of analysis separately, improving overall efficiency by avoiding unnecessary detailed simulations for positions that fail basic criteria
Solution Approach 2:
The patent applies a two-stage approach where a preliminary filtering action is performed on all positions, followed by partial simulation action only on the filtered subset. This partial action principle allows the system to perform complete detailed simulations only where necessary, rather than performing excessive simulations on all possible positions, thus optimizing the balance between accuracy and computational efficiency
