Solution Overview
Problem
The miniaturization of electronic devices is hindered by the increasing number of passive elements and noise generated by wiring patterns in power management integrated circuits (PMICs), which limits their compactness and multifunctionality.
Innovation Solution
A composite electronic component is designed with a power stabilization unit comprising a capacitor and inductor connected in series, along with switch units that maintain a constant resonance frequency through switching operations based on capacitance and inductance changes, and a terminal unit that includes input, output, and auxiliary terminals to optimize component placement and reduce noise.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the number of passive elements in PMIC is increased to satisfy multifunctional requirements, then the functionality of electronic devices is improved, but the area of component disposition is increased
Solution Approach 1:
The patent combines multiple passive elements (capacitors and inductors) into a single composite electronic component with integrated terminal structures. This merging reduces the overall area required for component disposition while maintaining the necessary multifunctional capabilities through the integrated design of the composite body containing multiple functional elements
2Adaptability or versatility
If the number of passive elements in PMIC is increased, then the power management capability is improved, but the device size is increased
Solution Approach 1:
The patent employs a nested structure where multiple passive elements (capacitors and inductors) are arranged within a composite body in a stacked configuration. The terminal unit extends from different surfaces of the composite body, allowing efficient space utilization and reducing the overall device volume while maintaining enhanced power management capability
3Power
If wiring patterns are added to PMIC for power input and output, then the power delivery is improved, but noise generation is increased
Solution Approach 1:
The patent extracts the power delivery function from traditional wiring patterns on a PCB and integrates it into a composite electronic component with dedicated input, output, and auxiliary terminals. This extraction consolidates power delivery pathways within a controlled structure, reducing electromagnetic interference and noise generation while maintaining effective power delivery capability
