Radiographic Imaging Battery Charging With Adaptive Current Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Radiographic imaging apparatuses with multiple batteries experience prolonged downtime due to decreased charging current when all batteries are charged simultaneously, leading to increased time before they become usable.
Innovation Solution
A current control unit determines the charging current for each battery based on the difference between its remaining charge and predetermined thresholds, optimizing the charging process to minimize downtime.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If all batteries are charged simultaneously with the same charging current, then the charging process is simple, but the charging time increases and downtime is prolonged
Solution Approach 1:
The patent applies local quality by assigning different charging currents to different batteries based on their individual remaining charge levels. The current control unit determines charging current for each battery according to the difference between its remaining charge and a predetermined threshold, so that batteries with lower charge receive higher current while those closer to full capacity receive less current. This differentiated approach optimizes charging efficiency and reduces overall charging time.
Solution Approach 2:
The patent implements dynamics by making the charging current adjustable and adaptive rather than fixed. The current control unit dynamically determines the charging current for each battery based on real-time remaining charge measurements and threshold comparisons. This dynamic adjustment allows the charging system to respond to changing battery states and optimize charging speed throughout the charging process.
2Productivity
If charging current is increased to reduce charging time, then productivity improves, but battery damage risk increases
Solution Approach 1:
The patent applies local quality by tailoring charging current to each battery's specific state. Instead of applying uniform high current to all batteries, the system assigns higher currents only to batteries with remaining charge below the threshold and lower currents to batteries closer to full capacity. This localized approach maximizes charging speed where safe while preventing damage through reduced current elsewhere.
Solution Approach 2:
The patent implements feedback through the current control unit that continuously monitors remaining charge levels and adjusts charging current accordingly. The system compares remaining charge against predetermined thresholds and modifies charging parameters in real-time, creating a closed-loop control mechanism that balances charging speed with battery protection.
