Segmented Magnetizing Yoke for Stable Coil Cartridge Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing magnetizing yokes face issues with reduced product lifespan due to coils being pushed outwards by radial forces, and require complete replacement upon breakdown, which is inefficient and costly.
Innovation Solution
A magnetizing yoke design featuring a base with segmented cores and coil cartridges secured by positioning members, including insulators and segmented cores with protrusions, prevents radial movement of coils and allows for partial replacement of parts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the coil is supported only by resin against radial inward force, then the structure is simple, but the coil may be pushed out inward reducing product lifespan
Solution Approach 1:
The core is divided into segmented cores that can be independently assembled and removed. Each segmented core includes positioning protrusions that engage with corresponding recesses in the stator, allowing the coil to be supported by multiple discrete positioning elements rather than relying solely on resin. This segmentation enables partial replacement of components without affecting the entire assembly.
Solution Approach 2:
Positioning members are introduced as intermediary components between the segmented cores and the stator. These positioning members include protrusions that fit into recesses, providing mechanical support and preventing radial displacement of the coil. The positioning members act as mediators that transfer and distribute the radial forces, reducing stress on the resin and coil.
2Stability of the object's composition
If the segmented core is press fitted in the stator, then the assembly is secure, but replacement of the entire apparatus is required in event of breakdown
Solution Approach 1:
The core is divided into multiple segmented cores that are arranged circumferentially around the coil. Each segmented core is independently supported by positioning members, allowing any single segmented core or the coil to be removed and replaced without affecting the other components. This segmentation transforms the entire apparatus replacement requirement into selective component replacement.
Solution Approach 2:
The positioning members are designed with movable characteristics, allowing the segmented cores to be easily inserted and removed from the stator. The protrusions and recesses provide guidance and alignment during assembly and disassembly, enabling dynamic reconfiguration and replacement of components without requiring complete disassembly of the entire apparatus.
3Reliability
If positioning members are added to prevent coil cartridges from moving inward, then coil displacement is prevented, but device complexity increases
Solution Approach 1:
The positioning members are merged with the segmented cores and stator structure. The protrusions on the positioning members engage with recesses that are integral parts of the stator and segmented cores, creating a unified positioning system. This merging reduces the need for separate, additional components while maintaining the coil position stability.

AI summary
The magnetizing yoke includes a base; a set of first segmented cores disposed on the base in a circumference, each of first segmented cores having a recess portion open inward in a radial direction corresponding to the circumference; a set of coil cartridges disposed inside the set of first segmented cores in the radial direction; and a set of positioning members positioning the set of coil cartridges relative to the base. Each of the coil cartridge includes: an insulator having a pair of walls facing each other in the radial direction; a coil disposed between the pair of walls; and a second segmented core including a protrusion received in the recess portion. The insulator, the coil, and the second segmented core are integral with each other. The set of positioning members prevent the set of coil cartridges from moving inward in the radial directions respectively. Each of coil cartridges is detachable from an assembly of the base, a first segmented core, and a positioning member.
