Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If high-power pulsed electromagnetic signals are transferred through cables to multiple applicators, then treatment coverage and versatility are improved, but electromagnetic energy leakage and cross-interference between applicators increase
Solution Approach 1:
A ground plane is introduced as an intermediary element between the coil and the cable connection. This ground plane acts as a mediator that confines the electromagnetic field, preventing energy leakage through the cable interface while maintaining the ability to transfer power and signals to multiple applicators simultaneously
Solution Approach 2:
The system divides the electromagnetic field containment into separate regions using individual ground planes for each applicator coil. This segmentation allows each applicator to be independently controlled and prevents cross-interference between multiple applicators while maintaining overall system versatility
2Productivity
If multiple applicators operate simultaneously with high-power pulsed signals, then treatment efficiency is improved, but cross-interference between applicators increases
Solution Approach 1:
Each applicator coil is paired with its own dedicated ground plane, creating electrically isolated segments. This segmentation allows multiple applicators to operate simultaneously at high power without cross-interference, as each ground plane confines the electromagnetic field to its respective applicator region
Solution Approach 2:
The ground planes serve as intermediary barriers between multiple applicators, blocking electromagnetic coupling between them. This intermediary structure enables simultaneous high-power operation of multiple applicators while preventing the harmful cross-interference that would otherwise reduce treatment reliability
3Loss of energy
If electromagnetic energy shields are added to reduce energy leakage, then energy containment is improved, but device complexity increases
Solution Approach 1:
Instead of using bulky three-dimensional electromagnetic shields, the patent employs thin planar ground planes that are simply connected between the coil and the cable interface. These thin film structures provide effective energy containment with minimal added complexity and bulk to the device
