Solution Overview
Problem
In aerosol generating devices, unstable electric power supply to the load results in varying aerosol production and reduced fragrance taste, and existing solutions do not adequately address the issue of capacitor mounting on circuit substrates without increasing their size.
Innovation Solution
A power supply unit for aerosol generating devices that includes a voltage converter, first and second capacitors connected between its output terminal and a connector, and a circuit substrate where the capacitors are not arranged in a line, allowing for efficient power stabilization and compact substrate design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple capacitors are mounted on the circuit substrate to stabilize power supply, then power supply stability is improved, but the circuit substrate size increases
Solution Approach 1:
The patent applies dimensionality change by arranging capacitors in a two-dimensional grid pattern rather than a linear one-dimensional arrangement. The capacitors are positioned at intersections of signal lines, utilizing the planar space of the circuit substrate more efficiently. This allows multiple capacitors to be mounted without extending the overall substrate dimensions, resolving the contradiction between power stability and substrate size.
Solution Approach 2:
The patent merges the functions of power stabilization and signal routing by positioning capacitors at the intersections of signal lines. This integration allows the capacitors to serve dual purposes: stabilizing power supply to connected components and being embedded within the signal distribution network without requiring additional dedicated space, thus maintaining compact substrate size while improving power stability.
2Ease of manufacture
If capacitors are arranged in a line on the circuit substrate, then mounting is simplified, but the substrate size increases
Solution Approach 1:
The patent transitions from linear one-dimensional capacitor arrangement to a two-dimensional grid pattern where capacitors are positioned at signal line intersections. This dimensional change maintains manufacturing simplicity through regular spacing and standardized mounting positions while dramatically reducing the substrate area required, as capacitors are distributed across the available plane rather than extending in a single direction.
3Ease of operation
If capacitors are positioned far from the voltage converter output terminal, then routing is easier, but power supply stability decreases
Solution Approach 1:
The patent merges capacitor positioning with signal line routing by placing capacitors exactly at the intersections where signal lines cross. This integration ensures capacitors are positioned close to the voltage converter output terminal for optimal power stability while simultaneously simplifying routing, as the capacitors are embedded within the existing signal distribution network rather than requiring separate routing paths.
