Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If multiple separate wire-wound electronic components are mounted on a circuit board, then each component can be independently connected, but the total mounting area becomes large
Solution Approach 1:
The patent combines multiple inductor windings into a single electronic component with one core. Multiple wires are wound around the same core structure, creating multiple inductors that share common magnetic path and physical space. This merging approach allows multiple inductance values to be obtained from a single component, dramatically reducing the mounting area compared to using separate components while maintaining independent electrical connection capabilities through multiple outer electrodes.
2Area of stationary object
If a single component contains multiple inductors, then mounting area is reduced, but the structural complexity increases
Solution Approach 1:
The patent segments the winding structure into multiple independent wire windings, each forming a separate inductor around the same core. Each wire can be independently connected to outer electrodes, allowing individual control and connection while sharing the common core structure. This segmentation enables multiple inductance values in a compact form factor without excessive structural complexity.
Solution Approach 2:
The core structure serves multiple functions simultaneously: it provides the magnetic path for multiple inductors, supports multiple wire windings, and enables various inductance combinations through different connection configurations. The single core structure is designed to accommodate multiple wires and provide multiple outer electrodes, making the component universally applicable for different inductance requirements.
3Area of stationary object
If multiple wires are wound on the same core, then mounting area is reduced, but the reliability of electrical connections becomes more challenging
Solution Approach 1:
Each wire winding is treated as an independent electrical path with dedicated outer electrodes for connection. The segmentation of electrical paths ensures that connection reliability of one inductor does not affect others, while the shared core provides mechanical support and magnetic coupling for all windings.
Solution Approach 2:
Multiple wire endings are connected to common outer electrodes that are mounted on the component body. This merging of connection points at the outer electrode level simplifies the connection process and improves reliability by providing robust solder joints external to the winding structure, while the individual windings maintain their electrical independence.
