Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional electromagnetic field therapy devices are used, then pain relief can be achieved, but extensive and regular treatment periods are required
Solution Approach 1:
The patent changes the operating parameters of the electromagnetic field device by using a toroidal coil configuration and specific frequency generation (250-350 kHz) to enhance treatment effectiveness. This allows achieving pain relief in shorter treatment periods compared to conventional devices, directly addressing the contradiction between reliability and time loss.
Solution Approach 2:
The patent incorporates a feedback loop that monitors the electromagnetic field output and adjusts the frequency generator accordingly. This feedback mechanism ensures optimal field delivery throughout treatment, improving effectiveness and reducing the need for extended treatment periods.
2Ease of operation
If electromagnetic field therapy devices are designed for personal use, then accessibility improves, but safety is not guaranteed
Solution Approach 1:
The feedback loop monitors operational parameters including temperature and field strength, automatically adjusting or shutting down the device if safety thresholds are exceeded. This makes the device safe for personal use while maintaining accessibility, resolving the contradiction between ease of operation and safety.
Solution Approach 2:
The device performs self-monitoring and self-regulation through its feedback mechanisms, automatically protecting itself and the user without requiring external supervision. This self-service capability enables safe personal use while eliminating the need for professional supervision.
3Productivity
If the toroidal coil operates for extended periods, then treatment capacity increases, but resistive heating increases
Solution Approach 1:
The feedback loop continuously monitors the coil temperature and adjusts the electrical signals to the toroidal coil accordingly. When temperature rises due to resistive heating, the system reduces power delivery or adjusts frequency to maintain safe operating temperatures while allowing extended treatment capacity.
Solution Approach 2:
The device uses pulsed electromagnetic field delivery with controlled duty cycles, allowing the coil to be energized in periodic bursts rather than continuous operation. This periodic action reduces cumulative heating while maintaining effective treatment capacity over extended periods.
4Loss of energy
If the coil resistance increases due to temperature, then energy loss increases, but electromagnetic output varies
Solution Approach 1:
The system dynamically changes the electrical signal parameters (frequency and amplitude) based on monitored coil conditions. When resistance increases due to heating, the feedback loop adjusts these parameters to compensate for the resistance change, maintaining consistent electromagnetic output while managing energy loss.
Solution Approach 2:
The feedback mechanism monitors electromagnetic output parameters and adjusts the frequency generator in real-time to maintain consistent field delivery despite resistance variations. This ensures reliable therapeutic effect while accepting controlled energy loss to manage heating.
