Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional magnetic flux irradiation devices face challenges in accurately positioning the coil relative to the affected area, particularly in confined spaces like the oral cavity, leading to reduced magnetic flux density and ineffective therapy due to diffusion of magnetic flux before reaching the target.
Innovation Solution
The development of magnetic flux irradiation devices with adjustable or replaceable magnetic cores that allow for customizable magnetic flux density patterns by adjusting the position of the magnetic core within the coil or swapping magnetic cores, enabling precise alignment and enhanced flux delivery to the target area.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the coil is positioned sufficiently close to the affected part to maintain magnetic flux density, then magnetic flux delivery is improved, but positioning accuracy deteriorates due to inability to accurately grasp the axis position of the coil from the outside
Solution Approach 1:
An auxiliary magnetic core is introduced as an intermediary component between the main magnetic core and the affected area. This auxiliary core extends the magnetic flux emission point closer to the target without requiring the main coil to be positioned extremely close, thereby maintaining flux density while avoiding positioning difficulties. The auxiliary core acts as a mediator that bridges the gap between the coil's limited accessibility and the need for high flux delivery.
2Quantity of substance
If the magnetic core or coil is brought closer to the affected area to prevent flux diffusion, then magnetic flux density is improved, but device operation becomes more difficult due to physical interference from surrounding structures
Solution Approach 1:
The magnetic core system is segmented into a main magnetic core and a separate auxiliary magnetic core. The auxiliary core can be independently positioned and adjusted, allowing it to be placed close to the affected area without moving the entire coil assembly. This segmentation enables the flux-emitting portion to be optimized for proximity to the target while the main coil remains in a more accessible position for operation.
3Device complexity
If a fixed magnetic core configuration is used, then device structure is simplified, but adaptability to different affected areas and anatomical locations deteriorates
Solution Approach 1:
The magnetic core system is made dynamic and adjustable rather than fixed. The auxiliary magnetic core can be repositioned along the axis of the coil, and different auxiliary cores with varying configurations can be used to adapt to different affected areas. This dynamic capability allows the device to maintain simplicity in basic structure while providing versatility through adjustable configurations.
4Ease of operation
If the coil is positioned far from the affected part due to physical interference, then ease of operation is improved, but magnetic flux density deteriorates due to diffusion of magnetic flux before reaching the target
Solution Approach 1:
The auxiliary magnetic core serves as a mediator that extends the magnetic flux pathway closer to the affected area without requiring the main coil to be positioned close to the target. This intermediary component maintains magnetic flux density by reducing the distance over which flux diffusion occurs, while allowing the main coil to remain in a more accessible position for operation.
