Winding Component Coil-Bobbin Alignment Without Rotation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing winding components require additional steps to rotate a bobbin for precise positioning, leading to potential inaccuracies in manufacturing and assembly.
Innovation Solution
A winding component with a first and second positioning mechanism, including a guide portion and locking portions, allows for easy insertion and accurate alignment of the bobbin and coil, utilizing engaging and locking portions to stabilize the bobbin and coil during assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the bobbin body is rotated to fix and position the coil, then the coil can be positioned, but the manufacturing process becomes more complex and time-consuming
Solution Approach 1:
The guide portion is pre-formed on the bobbin body to automatically guide the engaging portion of the coil into the correct position during insertion. This preliminary structural arrangement eliminates the need for post-insertion rotation operations, achieving both simple manufacturing and accurate positioning simultaneously
Solution Approach 2:
The guide portion acts as an intermediary mechanical element between the bobbin body and the coil. It mediates the positioning process by providing a physical path that directs the coil's engaging portion to the locking portion, replacing the complex rotation operation with a simple guided insertion motion
2Manufacturing precision
If the bobbin body is rotated to fix and position the coil, then the coil can be positioned, but the manufacturing time increases
Solution Approach 1:
The guide portion is pre-formed on the bobbin body to automatically guide the engaging portion of the coil into the correct position during insertion. This preliminary structural arrangement eliminates the need for post-insertion rotation operations, achieving both simple manufacturing and accurate positioning simultaneously
Solution Approach 2:
The invention skips the time-consuming rotation step entirely by designing the guide portion and engaging portion to work together during the insertion phase. The coil is positioned accurately during the insertion motion itself, rushing through the positioning process in a single motion rather than requiring separate rotation and locking steps

AI summary
The positioning can be performed at a plurality of positions by the first positioning mechanism and the second positioning mechanism. Further, the second positioning mechanism has a hole portion for receiving the second engaging portion as the second locking portion. By engaging the second engaging portion with the hole portion, the second positioning mechanism can restrict the displacement between the bobbin and the coil over the entire circumference. Thus, the bobbin and the coil can be accurately positioned. On the other hand, the first positioning mechanism includes a guide portion for relatively guiding the first engaging portion to the first locking portion along the insertion direction when the coil is inserted into the bobbin. Therefore, when the coil is inserted into the bobbin, the coil can be easily positioned only by moving the coil along the guide portion.
