Solution Overview
Problem
Magnetic Pulse Therapy Devices (MPTDs) with solenoid-based designs are limited by fixed longitudinal magnetic flux orientation, which may not optimally interact with cellular structures and nerve pathways, and manual applicators lack repeatability and precision in flux orientation.
Innovation Solution
Dynamic Directional Flux Control (DDFC) in a solenoid-based MPTD allows for precise control of magnetic flux orientation in multiple directions using a segmented solenoid with strategically energized and de-energized coil segments to create flux gaps, enabling dynamic redirection of magnetic fields.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a solenoid-based MPTD uses fixed longitudinal magnetic flux orientation, then the device structure is simple and reliable, but the therapeutic efficacy is limited due to lack of interaction with cellular structures and nerve pathways
Solution Approach 1:
The solenoid is divided into multiple independently controllable coil segments that can be selectively energized. This segmentation allows different portions of the solenoid to generate magnetic flux in different orientations simultaneously, transforming a single-orientation device into a multi-orientation device while maintaining the solenoid's structural simplicity and reliability.
Solution Approach 2:
The magnetic flux orientation is made dynamic through selective energization of different coil segments. The system can transition from static fixed orientation to dynamic variable orientation by controlling which segments are active, enabling adaptation to different therapeutic requirements without changing the physical device structure.
2Adaptability or versatility
If a manual applicator delivers multi-axial flux, then therapeutic interaction with cellular components is improved, but the device complexity increases and repeatability decreases
Solution Approach 1:
The manual applicator's complex multi-axial flux generation is replicated and simplified through segmented solenoid design. Each coil segment corresponds to a specific spatial region and can be independently controlled, providing the same flux orientation versatility as manual manipulation but with automated, repeatable precision.
Solution Approach 2:
The mechanical manipulation of flux orientation by a clinician is replaced with an electromagnetic control system. By using electronic control to selectively energize coil segments, the system achieves the same multi-axial flux capability without requiring manual dexterity, thereby increasing repeatability and reducing operational complexity.
3Stability of the object's composition
If a solenoid-based MPTD uses core flux with fixed axial orientation, then the magnetic field is coherent and consistent, but the therapeutic outcome is reduced due to lack of interaction with cellular structures
Solution Approach 1:
The coherent core flux is maintained in segments that are selectively activated to create localized multi-axial flux patterns. This allows the system to preserve the coherence and consistency of solenoid-generated flux while introducing directional variability through selective segment activation, thereby enhancing cellular interaction capability.
Solution Approach 2:
Different regions of the treatment zone are given different flux orientations by selectively energizing specific coil segments. This creates local quality variations in the magnetic field, where each region interacts with cellular structures in an optimized manner while maintaining overall flux coherence through the solenoid's unified magnetic circuit.

DDFC provides superior therapeutic outcomes by ensuring broader interaction with cellular components through varied flux orientations, enhancing treatment efficacy and usability for home-based therapy without manual assistance.
Implementation Method 1
A feature of solenoid-based therapeutic magnetic devices is that they primarily utilize core flux... When nerve cell membranes with embedded ion channels are exposed to magnetic flux, the induced electrical effects depend not only on the rate of change of the magnetic field
Implementation Method 2
When nerve cell membranes with embedded ion channels are exposed to magnetic flux, the induced electrical effects depend not only on the rate of change of the magnetic field but also on the orientation of flux lines relative to cellular structures

AI summary
A Magnetic Pulse Therapy Device (MPTD) configured to deliver dynamically oriented magnetic flux using a fixed applicator. The device includes a segmented solenoid with independently controlled coils arranged circumferentially around a treatment zone. Energizing specific solenoid segments with opposite polarities creates points of opposition, while leaving gaps between opposing segments allows flux to escape. The escaping flux can be oriented up to 90° from the core's longitudinal flux direction within the solenoid. This controlled flux manipulation enhances therapeutic effectiveness compared to conventional bipolar core flux. The device is suitable for both clinical and home applications.
