Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Radiographic imaging apparatuses with multiple batteries face inefficiencies in charging, leading to prolonged downtime due to reduced charging current when batteries are charged simultaneously.
Innovation Solution
A radiographic imaging apparatus with a charging unit that inputs current to multiple batteries while a current control unit determines the current input based on the difference between the remaining charge of each battery and predetermined thresholds.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple batteries are charged simultaneously, then the radiographic imaging apparatus can maintain readiness for imaging operations, but the charging current for each battery is reduced, leading to prolonged downtime
Solution Approach 1:
The patent applies local quality by differentiating the charging current allocated to each battery based on its individual state of charge. The control unit determines the charging current for each battery according to the difference between its remaining charge and a predetermined threshold, allowing batteries with lower charge levels to receive higher current priority. This resolves the contradiction by ensuring that while multiple batteries are charged simultaneously (maintaining readiness), each battery receives appropriate current allocation to minimize overall downtime.
2Device complexity
If a simple charging method is used for multiple batteries, then the device complexity is reduced, but the charging efficiency and speed are compromised
Solution Approach 1:
The patent implements feedback by having the control unit continuously monitor the remaining charge of each battery and adjust the charging current accordingly. The charging current for each battery is determined based on the difference between its remaining charge and a predetermined threshold, creating a closed-loop control system. This feedback mechanism resolves the contradiction by maintaining relatively simple device architecture while achieving high charging efficiency through intelligent current distribution based on real-time battery states.
