Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional steel electrodes with conductive gels are used for nerve stimulation, then electrical conduction is achieved, but the procedure becomes messy and less convenient
Solution Approach 1:
The patent extracts and removes the conductive gel component from the electrode system, replacing it with dry elastomer electrodes that achieve electrical conduction through direct skin contact. This eliminates the messiness associated with gel application while maintaining the essential electrical conduction function.
Solution Approach 2:
The patent changes the physical state of the electrode material from wet/gel-based to dry elastomer. This parameter change in the material state allows the electrode to function without conductive gel, thereby eliminating the harmful messiness while preserving electrical conduction capabilities.
2Measurement precision
If distance measurement is performed with traditional measuring tapes, then the procedure is simple, but measurement precision is insufficient
Solution Approach 1:
The patent merges the distance measurement function directly into the stimulator device by integrating a distance measurement module. This combination eliminates the need for separate measuring tapes while providing precise digital measurements, thereby improving measurement precision without significantly increasing overall system complexity.
Solution Approach 2:
The patent replaces the mechanical measuring tape system with an electronic distance measurement module that uses sensors and digital processing. This substitution provides more precise measurements while integrating the function into the existing device, avoiding the need for separate manual measurement tools.
3Measurement precision
If electrodes are placed at specific distances for nerve conduction testing, then accurate conduction velocity calculation is possible, but the process becomes time-consuming
Solution Approach 1:
The patent incorporates a distance measurement module that automatically measures and stores the distance between electrodes during the setup phase. This preliminary automatic measurement eliminates the need for manual measuring during the actual test, thereby reducing the time required for the procedure while maintaining measurement accuracy for conduction velocity calculations.
Solution Approach 2:
The patent implements real-time distance measurement and feedback through the integrated distance measurement module. The system continuously monitors and provides feedback on the distance between electrodes, allowing for immediate adjustment and verification. This feedback mechanism ensures accurate measurements are obtained quickly, reducing the time required for proper electrode placement and distance verification.
