Coil Component Guide Members Prevent Positional Bias
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Winding-type coil components often experience manufacturing defects and characteristic deterioration due to bias during production, leading to exposure and reduced performance.
Innovation Solution
Incorporating guide members spaced along the outer periphery of the winding coil within a body, which restricts movement and stabilizes the coil during manufacturing, allowing for compact and mass-producible coil components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If winding-type coil components are manufactured using a simple method, then manufacturing complexity is reduced, but the coil may become biased and exposed externally during manufacturing
Solution Approach 1:
Guide members are pre-installed in the body at predetermined positions before the coil is placed. These guide members create physical constraints that automatically guide the coil into the correct position during assembly, preventing bias and exposure issues before they occur during manufacturing
Solution Approach 2:
Guide members act as intermediary elements between the body and the coil. They provide a mechanical interface that restricts coil movement and maintains proper positioning without requiring complex manufacturing processes or additional adjustment steps
2Volume of moving object
If the coil component is made compact, then device size is reduced, but the coil may become unstable and difficult to mount
Solution Approach 1:
Rather than increasing the overall component size, guide members are strategically positioned at specific locations where the coil is most prone to movement or exposure. This localized approach provides stability exactly where needed while maintaining the compact overall dimensions of the component
3Manufacturing precision
If guide members are added to restrict coil movement, then manufacturing precision is improved, but device complexity increases
Solution Approach 1:
The positioning function is segmented from the main body structure and implemented through separate, discrete guide members. This allows the guide members to be independently manufactured and positioned, simplifying the overall manufacturing process while achieving precise coil positioning
Solution Approach 2:
The guide members are designed as simple, inexpensive structural elements that can be easily manufactured and integrated into the body. Their simple geometry and material requirements keep them cost-effective, offsetting the added complexity of having multiple components

AI summary
A coil component includes a body having a winding coil and a plurality of guide members therein. The guide members are spaced apart from each other along an outer periphery of the winding coil, and each of the guide members has an exposed surface exposed externally of the body. A method for manufacturing a coil component includes seating opposing ends of a winding coil on a support member of a frame having guide members restricting movement of the winding coil relative to the frame. A body is formed that embeds the winding coil and at least a portion of each of the guide members therein, and the guide members restrict movement of the winding coil during the forming of the body.
