Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing inductors require significant redesign and increased time or costs when configuring for different inductance values, making it inconvenient to achieve various inductance values efficiently.
Innovation Solution
The inductor design includes at least two inductor structures with a single coil, a magnetic body, an electrode structure, and a protection structure. The electrode structure has spaced-apart electrodes separated by a protection structure, allowing for arbitrary combinations of inductor structures to achieve various inductance values.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the configuration of the inductor is redesigned each time a new inductance value is expected, then the inductance value can be adjusted, but considerable time or design costs will be incurred
Solution Approach 1:
The inductor structure is divided into multiple inductor structures that can be independently configured and combined. Each inductor structure contains a single coil with specific characteristics, and by selectively combining these segmented structures, different inductance values can be achieved without complete redesign
Solution Approach 2:
The standardized inductor structure design serves multiple functions: it can be used as a basic unit for different inductance values, can be combined in series or parallel configurations, and can accommodate different coil specifications while maintaining the same structural framework, thereby reducing design time for various inductance requirements
2Adaptability or versatility
If the configuration of the inductor is redesigned each time a new inductance value is expected, then the inductance value can be adjusted, but design costs will increase
Solution Approach 1:
By segmenting the inductor into standardized modular structures, the design process is simplified and can be reused across different products, reducing engineering hours and design costs while maintaining adaptability for different inductance values
Solution Approach 2:
Instead of redesigning the entire structure, only specific parameters such as the number of turns, wire gauge, or coil dimensions are changed while keeping the overall structural framework the same, thereby reducing design complexity and cost
3Area of stationary object
If electrodes are placed close together to reduce space, then the device size is reduced, but the reliability decreases due to potential short circuits
Solution Approach 1:
A protection structure is introduced as an intermediary element between the first electrode and the second electrode. This protection structure physically separates the electrodes, preventing short circuits while allowing the electrodes to be positioned closer together, thus reducing device area without compromising reliability
