Solution Overview

Problem

There is a need for a Magnetic Pulse Therapy Device (MPTD) that can safely and effectively treat foot pain, suitable for in-home self-administration, as existing devices are either unsafe for home use or ineffective due to low flux density and applicator size limitations.

Innovation Solution

A novel applicator design using a multiplicity of axially aligned low-voltage coils forming an operative solenoid, allowing a foot to be easily slid in and out, which delivers a medically effective dose of magnetic pulses uniformly across the entire foot without high voltages or thermal risks.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If high-power MPTDs are used to achieve clinical efficacy, then pain relief effectiveness is improved, but safety and suitability for home use deteriorates due to high voltage and thermal risks

Engineering Contradiction:
Improvepain relief effectivenessVSAvoidsafety risks from high voltage and thermal effects
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent divides the treatment system into multiple low-voltage coils arranged in series, where each coil generates a small magnetic pulse. The cumulative effect of these segmented pulses achieves the same therapeutic dosage as a single high-power pulse, thereby maintaining clinical efficacy while eliminating high voltage and thermal safety concerns

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent changes the voltage parameter from high voltage to low voltage operation. By using multiple low-voltage coils in series, the system achieves the required magnetic flux density through cumulative effect rather than high voltage, fundamentally altering the safety profile while maintaining therapeutic effectiveness

Inventive Principle:
Principle #35Parameter changes

2Reliability

If existing MPTDs are designed for clinical use, then treatment effectiveness is improved, but ease of operation and suitability for self-administration deteriorates

Engineering Contradiction:
Improvetreatment effectivenessVSAvoidsuitability for self-administration
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The patent designs the applicator with a simple insert/removal mechanism that allows patients to self-administer treatment without clinical supervision. The device automatically delivers the therapeutic pulses once the foot is inserted, eliminating the need for skilled operation while maintaining clinical effectiveness

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent ensures uniform magnetic flux distribution across the entire foot by arranging coils in a homogeneous pattern. This uniform dosage distribution simplifies the treatment process for self-administration, as no positioning adjustments are needed, while maintaining consistent therapeutic effectiveness

Inventive Principle:
Principle #33Homogeneity

3Area of stationary object

If applicator size is increased to treat the entire foot, then treatment coverage is improved, but device complexity and manufacturing difficulty worsens

Engineering Contradiction:
Improvetreatment coverage areaVSAvoidapplicator design complexity
Core Design Contradiction:
Area of stationary objectVSDevice complexity

Solution Approach 1:

The patent segments the large applicator into multiple smaller coils arranged in series along the foot. This segmentation allows the entire foot to be treated through cumulative magnetic flux from multiple simple coil units, avoiding the complexity of designing a single large applicator while achieving comprehensive coverage

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent merges the functions of multiple coils into a single series circuit configuration. By combining the magnetic flux effects of individual coils through series connection, the system achieves treatment of the entire foot using simple, modular coil units rather than a complex integrated applicator

Inventive Principle:
Principle #5Merging (Combining)

4Reliability

If flux density is increased to achieve medical efficacy, then pain relief effectiveness is improved, but thermal effects and safety risks worsen

Engineering Contradiction:
Improvemedical efficacyVSAvoidthermal effects
Core Design Contradiction:
ReliabilityVSTemperature

Solution Approach 1:

The patent segments the high flux density requirement into multiple low-flux-density pulses delivered in sequence. The cumulative effect of these segmented pulses achieves the required therapeutic flux density without concentrating thermal energy, thereby maintaining medical efficacy while minimizing thermal effects

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent uses periodic pulsing of the magnetic field rather than continuous high-flux-density application. By delivering flux in periodic pulses, the system achieves cumulative therapeutic effect while allowing heat dissipation between pulses, thereby maintaining efficacy while controlling thermal effects

Inventive Principle:
Principle #19Periodic action

AI summary

For foot pain sufferers, especially those with peripheral neuropathy, this invention introduces a breakthrough device. Its key feature is a novel self-aligning applicator that simultaneously treats the entire foot and eliminates adjustments and sizing. A large enough and powerful enough treatment zone is possible by utilizing a segmented solenoid and by placing the foot directly into its coherent core flux. Dosages to the entire foot of 2,500ΣΔBT can be achieved within an hour. Extremely low voltages are used, and very little heat is produced, making the device suitable for in-home use.
