Solution Overview
Problem
When using pancake-winding devices to produce three-dimensional superconducting coils from tape-like superconducting wires, the wire position shifts in the width direction, causing stress and deformation that deteriorates the superconducting properties.
Innovation Solution
A superconducting coil production apparatus and method that includes a rotary driving unit for the coil bobbin and an adjustment driving unit to maintain the wrapping point position relative to the supply reel's axis direction, preventing edgewise distortion by synchronizing the rotation and adjustment of the coil bobbin and supply reel.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a pancake-winding device is used to wind tape-like superconducting wire on a three-dimensional coil, then the coil can be produced with a complex three-dimensional shape, but the wire position shifts in the width direction causing stress and deformation that deteriorates superconducting properties
Solution Approach 1:
The invention makes the coil bobbin rotatable around its coil axis while maintaining the wire supply geometry. The coil bobbin is rotated by a rotary driving unit to form three-dimensional windings, while the supply reel maintains a fixed geometric relationship with the wire wrapping point, dynamically adjusting the winding configuration without compromising wire position accuracy
Solution Approach 2:
The invention separates the functions of coil formation and wire supply into independent components. The coil bobbin rotation function is separated from the wire supply function, allowing the supply reel to maintain a fixed geometric relationship with the wrapping point while the coil bobbin rotates to create three-dimensional shapes
2Shape
If the coil bobbin is rotated around one axis to create three-dimensional winding, then the coil can be formed with steric shape, but stress is generated that deforms the wire in the edgewise direction
Solution Approach 1:
The invention introduces a geometric relationship constraint as an intermediary between the coil bobbin rotation and wire supply. The supply reel is positioned such that its rotational axis direction aligns with the wire wrapping point, creating a geometric mediator that prevents edgewise stress during three-dimensional winding

AI summary
According to an embodiment, a superconducting coil production device for producing a non-coplanar three-dimensional superconducting coil by winding a tape-like superconducting wire includes: a coil bobbin; a supply reel to supply the superconducting wire to the coil bobbin; and an adjustment driving unit to adjust a position of the supply reel relative to a wrapping point so that a position of the wrapping point of the coil bobbin around which the superconducting wire being supplied from the supply reel is wrapped becomes equal to a position of the supply reel in a rotational axis direction of the supply reel.
