Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If PEMF generators are made large and stationary to ensure therapeutic effectiveness, then the micromagnetic field generation capability is improved, but the portability deteriorates
Solution Approach 1:
The patent divides the traditional large stationary PEMF generator into portable segments by using battery power sources and compact coil assemblies that can be easily transported and positioned near the patient, while maintaining the essential therapeutic function through optimized electromagnetic field generation components
Solution Approach 2:
The invention implements dynamic control of the micromagnetic field parameters through a microcontroller that adjusts frequency, amplitude, and pulse width based on pre-programmed protocols, allowing the device to adapt therapeutic parameters automatically while maintaining portability and ease of use
2Ease of operation
If the device includes multiple control components and memory for storing protocols, then the ease of operation is improved, but the device complexity increases
Solution Approach 1:
The microcontroller serves multiple functions simultaneously: it stores treatment protocols in memory, processes user input from buttons, controls the H-bridge circuit for coil activation, manages battery power distribution, and handles display output, thereby reducing the need for separate dedicated components for each function
Solution Approach 2:
The patent combines the power control circuitry, signal generation, memory storage, and user interface into an integrated circuit board assembly that works in unison with the battery and coil components, creating a unified portable system where components are optimized to work together rather than as separate complex subsystems
