Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing apparatuses for generating pulsed magnetic fields face limitations in increasing the width of the utilizable field region without expanding the overall apparatus size, particularly in PEMF therapy for treating non-union and delayed union bone fractures and soft tissue injuries.
Innovation Solution
The apparatus incorporates an electrical conductor with a gap, allowing current to flow in parallel, positioned within a ferromagnetic body, which enhances the magnetic field distribution and increases the width of the utilizable field region without increasing the distance between conductor segments, thus maintaining a compact design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the distance between conductor segments is increased to expand the utilizable field region, then the width of the utilizable field region increases, but the overall apparatus size increases
Solution Approach 1:
The electrical conductor is divided into multiple segments with gaps between them, allowing current to flow through multiple parallel paths. This segmentation enables the magnetic field to be generated across a wider effective area without requiring a larger overall apparatus structure, as the gaps allow field penetration while maintaining compact dimensions
Solution Approach 2:
The invention transitions from a single continuous conductor to a multi-segmented conductor arrangement, effectively utilizing the dimensional space created by gaps. This allows the magnetic field to extend into regions that would otherwise be blocked, increasing the utilizable field region width without proportionally increasing the apparatus volume
2Area of stationary object
If a continuous electrical conductor is used, then the structure is simple, but the width of the utilizable field region is limited
Solution Approach 1:
The electrical conductor is divided into multiple segments with gaps between them, allowing current to flow through multiple parallel paths. This segmentation enables the magnetic field to be generated across a wider effective area without requiring a larger overall apparatus structure, as the gaps allow field penetration while maintaining compact dimensions
Solution Approach 2:
The gaps between conductor segments act as intermediaries that allow magnetic field lines to penetrate and extend into the surrounding space. These gaps serve as mediators that enable the magnetic field to reach broader regions without requiring the conductor itself to be physically larger or more complex
