Integrated Inductor Framework for Reduced PCB Footprint
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional inductor frameworks with pins occupy a large area on printed circuit boards (PCBs) due to the need for pins to pass through bonding pads, limiting efficiency and space utilization.
Innovation Solution
An inductor framework with a main winding part and auxiliary winding parts that are integrally arranged, allowing for the winding of auxiliary coils that cover a portion of the welding surface, reducing the need for pin-based connections and minimizing PCB area usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If pins are used for connection in conventional inductor frameworks, then structural stability is improved, but PCB area occupation increases
Solution Approach 1:
The patent removes the pin component from the inductor framework structure. Instead of using separate pins for connection, the framework directly integrates connection terminals that extend from the framework body itself, eliminating the need for pins while maintaining structural stability and reducing PCB area occupation.
Solution Approach 2:
The patent merges the connection function into the framework structure itself. The inductor framework integrates both the inductive function and the connection function by forming connection terminals directly from the framework material, combining what were previously separate components (framework and pins) into a unified structure.
2Ease of manufacture
If pins are used for connection, then ease of manufacture is improved through standardized processes, but device complexity increases due to additional components
Solution Approach 1:
The patent merges the connection function into the framework structure itself. The inductor framework integrates both the inductive function and the connection function by forming connection terminals directly from the framework material, combining what were previously separate components (framework and pins) into a unified structure.
Solution Approach 2:
The framework structure serves multiple functions simultaneously: it provides the inductive path, mechanical support, and electrical connection terminals. This multi-functionality reduces the number of separate components needed while maintaining ease of manufacture through integrated design.
