Parallel Plate-Wound Coil Structure for Higher Current Capacity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Typical coil devices face limitations in increasing their current-carrying capacity due to the thickness constraints of the plate material used in the coil, which restricts the amount of current that can flow through the device.
Innovation Solution
The coil device incorporates two spirally wound coils with plate-shaped bodies, where the second coil is in electrically parallel connection with the first coil, allowing current to flow through both coils, thereby increasing the current-carrying capacity without requiring thicker plate materials.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the plate material thickness is increased to increase the current-carrying capacity, then the current-carrying capacity improves, but the device complexity and manufacturing difficulty increase
Solution Approach 1:
The patent divides the coil structure into multiple separate coils (first coil and second coil) that are wound on the same columnar portion of the core. Each coil uses standard thickness plate material, but together they provide increased current-carrying capacity through parallel electrical connection, avoiding the need to manufacture thicker plate materials.
Solution Approach 2:
The patent combines multiple coils electrically in parallel to achieve the effect of increased current-carrying capacity. The first coil and second coil are both connected to the same terminals, creating parallel current paths that effectively increase the total current capacity without requiring thicker individual plate materials.
2Quantity of substance
If the plate material thickness is increased to increase the current-carrying capacity, then the current-carrying capacity improves, but the ease of manufacture deteriorates
Solution Approach 1:
The patent segments the coil function into multiple separate coils that can each be manufactured using standard plate material thicknesses. This avoids the manufacturing challenges of producing thick plate materials while achieving the same current-carrying capacity through parallel configuration.
3Quantity of substance
If multiple coils are added to increase the current-carrying capacity, then the current-carrying capacity improves, but the device complexity increases
Solution Approach 1:
The patent merges multiple coils into a unified structure by winding them on the same columnar portion of the core and connecting them in parallel electrically. This integration approach minimizes the increase in device complexity compared to using separate coil assemblies, as the multiple coils share common mounting space and electrical terminals.

AI summary
A coil device includes a first coil including a plate-shaped first coil body having a first and second end. The first coil body is spirally wound on a columnar portion along the extending direction of the columnar portion such that the second end is positioned on one side in the extending direction relative to the first end. The coil device further includes a second coil including a plate-shaped second coil body having a third end and a fourth end. The second coil body is spirally wound on the columnar portion along the extending direction such that the third end is positioned on the one side in the extending direction relative to the second end of the first coil, and the fourth end is positioned on the one side in the extending direction relative to the third end. The second coil is in electrically parallel connection with the first coil.
