Magnetic Core Housing With Reinforced Metal Spring Contact
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing noise reduction devices using resin-elastic claws to bring divided magnetic cores into contact with each other suffer from deterioration over time, leading to insufficient force application and poor contact, which affects their noise reduction efficacy.
Innovation Solution
A magnetic core housing using metal springs with reinforcing means to maintain contact between divided magnetic cores, ensuring a sufficient force is applied by using metal springs with inclined parts and reinforcing structures to prevent bending, thereby maintaining close contact.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If resin elastic claws are used to apply force to magnetic cores, then the device can be manufactured with simple materials, but the spring deteriorates with time due to creep characteristics and cannot apply sufficient force
Solution Approach 1:
The patent changes the material parameter of the spring from resin to metal, fundamentally altering the creep characteristics and durability while maintaining the spring's functional form and force application mechanism
Solution Approach 2:
The patent creates a composite structure combining metal spring (for force application) with resin housing (for structural support and insulation), where each material is used where it provides optimal properties
2Reliability
If metal springs are used to replace resin elastic claws, then the force application reliability is improved, but the planar part may bend due to forces transmitted from spring parts
Solution Approach 1:
The patent divides the spring into distinct functional segments: inclined spring parts for force generation and a planar part for force transmission, allowing each segment to be optimized for its specific function
Solution Approach 2:
The patent adds reinforcing ribs that extend in the thickness direction of the planar part, transitioning from a two-dimensional planar structure to a three-dimensional reinforced structure that resists bending forces
3Manufacturing precision
If the magnetic core housing is designed with divided sections and elastic claws, then the magnetic cores can be brought into close contact on division surfaces, but the contact quality deteriorates over time due to spring deterioration
Solution Approach 1:
The patent changes the material parameter of the spring from resin to metal, fundamentally altering the creep characteristics and durability while maintaining the spring's functional form and force application mechanism

AI summary
A magnetic core housing capable of applying a sufficient force to a magnetic core is provided. A magnetic core housing according to an aspect of the disclosure includes first and second housings each capable of housing a core, a hinge configured to connect the first and second housings with each other so that they can be opened and closed with respect to each other, and a metal spring disposed in the first housing. The metal spring includes a planar part and a pair of spring parts, and also includes reinforcing means for preventing the planar part from being bent due to a force transmitted from the pair of spring parts when the core is housed in the first housing.
