Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If light pulse therapy devices use a dedicated power source, then they can provide sufficient energy for light pulses, but the device becomes large and bulky
Solution Approach 1:
The pulsed EMF device is designed to perform dual functions: generating pulsed electromagnetic fields for therapeutic purposes and simultaneously serving as a power source for light pulse generation through electromagnetic induction. This eliminates the need for a separate dedicated power source for light pulses, reducing device size while maintaining sufficient energy supply for both functions
Solution Approach 2:
The patent combines the pulsed EMF generator and light pulse generator into a single integrated system. The coil loop of the pulsed EMF device induces current that powers the light generating unit, merging two previously separate functions into one unified device, thereby reducing overall device size and weight
2Ease of manufacture
If pulsed EMF device and light therapy device are separate, then each can be optimized independently, but energy transfer efficiency is reduced and device complexity increases
Solution Approach 1:
The patent integrates the light therapy function directly into the pulsed EMF device by positioning a light generating unit near the coil loop. The electromagnetic field generated by the coil loop directly induces current in the light generating unit, creating an efficient energy transfer pathway that eliminates intermediate energy conversion steps and reduces energy loss
3Ease of operation
If EMF pulse and light pulse are not synchronized, then device operation is simpler, but physiological effects are reduced
Solution Approach 1:
The system generates periodic pulsed electromagnetic fields that automatically induce periodic current pulses in the light generating unit at the same frequency. This inherent periodic synchronization ensures that EMF pulses and light pulses occur simultaneously without requiring complex control circuits, maintaining operational simplicity while achieving reliable synchronized therapeutic effects
Solution Approach 2:
The electromagnetic induction process creates an automatic feedback mechanism where the EMF pulse waveform directly determines the light pulse waveform through induced current. The system self-regulates to maintain synchronization between EMF and light pulses based on the inherent electromagnetic coupling, ensuring reliable physiological effects without complex external control
