Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing inductor devices, such as spiral and 8-shaped inductors, face limitations in mutual inductance and space occupancy, which restrict their performance and application range.
Innovation Solution
An inductor device comprising a conductor with a first and second ring-type structure coupled by a connector, allowing selective connection to form either a single loop or an 8-shaped inductor, thereby providing various inductances and expanding the serviceable range.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If spiral type inductor is used, then Q value and mutual inductance are improved, but coupling condition occurs amongst coils
Solution Approach 1:
The inductor is divided into two separate ring-type structures (first and second ring-type structures) that can be independently controlled. By segmenting the conductor into distinct rings with selective connectivity, the design achieves high Q values while allowing control over mutual inductance coupling between the rings through the connector.
2Reliability
If 8-shaped inductor is used, then mutual inductance occurs at another coil, but space occupancy increases
Solution Approach 1:
The inductor structure is made dynamically reconfigurable through the connector that can selectively connect or disconnect the first and second ring-type structures. This allows the device to switch between different inductance modes (single loop or dual loop with mutual inductance) and adjust space occupancy based on operational requirements.
3Adaptability or versatility
If connector selectively connects ring-type structures, then various inductances are generated, but device complexity increases
Solution Approach 1:
The connector serves multiple functions: it selectively connects the first and second ring-type structures to generate different inductance values, controls mutual inductance coupling, and enables the inductor to adapt to various application requirements. This multi-functionality achieves inductance variability without proportionally increasing device complexity.

AI summary
An inductor device includes a conductor and a connector. The conductor includes a first ring-type structure and a second ring-type structure. The second ring-type structure is coupled to the first ring-type structure. The connector is coupled to the first ring-type structure and the second ring-type structure, and is configured to selectively connect the first ring-type structure and the second ring-type structure such that the conductor forms single loop.
