Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the user manually controls the current intensity of the low-frequency electrotherapy instrument, then the device is simple to operate, but excessive current intensity may cause harm to the user
Solution Approach 1:
The patent implements a feedback mechanism where the electromyography measurement circuit continuously monitors the user's muscle response during electrotherapy treatment. The processor uses this real-time feedback information to automatically adjust the current intensity, preventing excessive intensity from causing harm while maintaining ease of operation for the user.
Solution Approach 2:
The system performs self-regulation by automatically determining and adjusting the current intensity based on real-time electromyography measurements. This eliminates the need for manual intensity control by the user, as the system serves itself by monitoring and adjusting parameters to prevent harmful effects.
2Measurement precision
If the medical personnel control the electrotherapy instrument, then the current intensity can be precisely controlled, but the device complexity increases due to additional control mechanisms
Solution Approach 1:
The electrotherapy instrument performs automatic intensity determination through its integrated electromyography measurement circuit and processor. The system self-regulates the current intensity based on real-time muscle response monitoring, eliminating the need for external medical personnel control while maintaining precise intensity adjustment.
Solution Approach 2:
The system uses real-time feedback from electromyography measurements to automatically adjust current intensity. This closed-loop control mechanism achieves precise intensity control without requiring complex manual control interfaces or external monitoring systems.
3Productivity
If the current intensity is increased to improve therapeutic effects, then the treatment effectiveness improves, but the risk of causing harm to the user increases
Solution Approach 1:
The electromyography measurement circuit provides real-time feedback on the user's muscle response to the electrotherapy treatment. The processor uses this feedback to dynamically adjust the current intensity, increasing it when therapeutic effects are needed and reducing it when approaching harmful thresholds, thus balancing effectiveness and safety.
Solution Approach 2:
The system dynamically adjusts the current intensity during the electrotherapy treatment based on real-time electromyography measurements. Rather than using a fixed intensity level, the system adapts the intensity throughout the treatment process to optimize therapeutic effects while preventing harm.
