Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed frequency and intensity of magnetic field pulse is used for all users, then the device structure is simple and easy to operate, but the stimulation depth and intensity cannot be optimized for individual muscle mass and fat layer thickness
Solution Approach 1:
The patent implements dynamic adjustment of magnetic field pulse parameters (frequency and intensity) based on real-time detection of muscle contraction status. The controller continuously monitors electromyography (EMG) signals and automatically adjusts stimulation parameters to optimize effectiveness for each individual's muscle mass and fat layer thickness, transforming the fixed-parameter system into an adaptive dynamic system.
Solution Approach 2:
The patent employs a feedback mechanism where the controller detects muscle contraction through EMG sensors and uses this information to adjust the magnetic field pulse parameters. The detected muscle response feeds back to the controller, which then optimizes the stimulation parameters, creating a closed-loop control system that adapts to individual user characteristics.
2Reliability
If the magnetic field pulse parameters are adjusted during treatment based on muscle mass and fat layer thickness, then stimulation effectiveness is improved, but the control complexity and measurement requirements increase
Solution Approach 1:
The patent enables the system to automatically determine optimal stimulation parameters by detecting muscle contraction responses during the treatment process. The controller uses real-time EMG signal analysis to self-adjust frequency and intensity without requiring external manual measurement of muscle mass or fat layer thickness, making the system self-adapting to individual user characteristics.
Solution Approach 2:
The patent performs preliminary detection of muscle characteristics and conducts a test stimulation phase before the main treatment. The controller measures muscle response during this preliminary phase and uses the obtained data to pre-calculate optimal parameters for the subsequent treatment, ensuring effectiveness while simplifying the main treatment process.
3Ease of operation
If electromagnetic sensors are used to detect muscle contraction for parameter adjustment, then personalized stimulation is achieved, but the device complexity and cost increase
Solution Approach 1:
The patent combines the electromagnetic sensor detection function with the existing magnetic field stimulation apparatus into an integrated system. The EMG sensors are incorporated into the applicator design, and the control unit that processes sensor data is merged with the power supply unit that generates magnetic field pulses, creating a unified device that reduces overall system complexity despite adding sensing capabilities.
