Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing filter components with windingless toroidal cores face challenges in manufacturing simplicity, modular expansion, and assembly complexity, particularly requiring laborious molding or complex folding mechanisms for fastening to conductors.
Innovation Solution
A filter component design featuring a windingless magnetic toroidal core with a central opening and a snap-on toroidal core housing that allows easy assembly and modular expansion, eliminating the need for molding or complex folding by enabling the conductor to be run through the core after assembly, and providing a fastening surface for attachment to a fastening element.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a windingless toroidal core is used with molding to fasten to the conductor, then the assembly is simple, but the manufacturing process becomes laborious and time-consuming
Solution Approach 1:
The filter component is divided into separate modular sections, each with its own housing and toroidal core. The housing includes a receiving space that accommodates the toroidal core without requiring molding or complex fastening to the conductor. This segmentation allows independent assembly of each module, improving manufacturing efficiency while maintaining assembly simplicity.
Solution Approach 2:
The toroidal core is pre-positioned within the housing's receiving space before final assembly. The housing is designed with a snap-fit mechanism that secures the core in place during the molding process, eliminating the need for post-assembly fastening operations and reducing manual labor requirements.
2Adaptability or versatility
If a folding core with two hollow cylinder halves is used, then the core can be fastened around the conductor by compression, but the manufacturing becomes complex and requires different cores for each size
Solution Approach 1:
The housing is designed as a universal component that can accommodate toroidal cores of different sizes through the same snap-fit mechanism. The receiving space within the housing can be adjusted or selected to fit various core dimensions, eliminating the need for different housing designs for each core size and simplifying manufacturing.
Solution Approach 2:
The design allows for parameter changes in the toroidal core dimensions while maintaining the same housing structure. The snap-fit mechanism can be adjusted to accommodate different core sizes by modifying the receiving space dimensions, enabling a single housing design to serve multiple core size requirements.
3Adaptability or versatility
If a housing cover with complex mounting is used to hold the toroidal core, then the housing can be concatenated modularly, but the mounting becomes time-consuming and complex
Solution Approach 1:
The housing cover is merged with the main housing body through a snap-fit mechanism that integrates the mounting function directly into the housing structure. This eliminates the need for separate complex mounting operations and allows modular sections to be quickly connected by simply snapping the housings together, reducing assembly time while maintaining modular expandability.
4Reliability
If the toroidal core is fastened to the conductor by molding or folding mechanisms, then the connection is secure, but the assembly procedure becomes laborious and complex
Solution Approach 1:
The toroidal core is extracted from the conductor fastening process and positioned independently within the housing's receiving space. The housing then provides the secure connection function through its snap-fit mechanism, separating the core positioning function from the conductor fastening function. This allows the core to be securely held without requiring direct fastening to the conductor, simplifying the assembly procedure while maintaining connection security.
