Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing charging technologies fail to efficiently manage and prioritize charging among multiple electronic devices connected to a charging device, leading to inappropriate charging scenarios.
Innovation Solution
A charging device and electronic device system that includes units for acquiring and managing charging priority based on remaining battery levels and location information, enabling efficient charging by determining priority and optimizing power distribution among connected devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If charging is performed without considering remaining battery levels and device states, then charging can be implemented simply, but charging efficiency and appropriateness deteriorate
Solution Approach 1:
The charging device acquires remaining battery level information from multiple electronic devices and uses this feedback to dynamically determine charging priority. The charging management unit continuously monitors battery states and adjusts charging allocation accordingly, ensuring efficient power distribution based on actual device needs rather than static rules
Solution Approach 2:
The charging priority is not fixed but dynamically determined based on real-time battery states of connected devices. The system adapts charging allocation as device states change, with the charging management unit recalculating priorities based on current remaining battery levels and device requirements
2Reliability
If charging priority is determined based on remaining battery levels and device states, then charging appropriateness is improved, but information acquisition and processing complexity increases
Solution Approach 1:
Each electronic device autonomously reports its own remaining battery level and state information to the charging device. This self-service approach eliminates the need for the charging device to actively query or complexly infer device states, reducing information processing complexity while maintaining accurate charging priority determination
Solution Approach 2:
The charging device determines charging priority in advance based on acquired battery state information before actual charging begins. This preliminary determination allows the system to prepare optimal charging allocation strategies, ensuring appropriate charging from the start without continuous complex adjustments during charging
3Adaptability or versatility
If multiple electronic devices are connected to the charging device, then charging versatility is improved, but charging management difficulty increases
Solution Approach 1:
The charging management function is segmented into automatic priority determination and user confirmation. The charging management unit automatically calculates charging priorities for each connected device based on their battery states, then presents this information to the user for final confirmation. This segmentation handles the complexity of multi-device management automatically while keeping user interaction simple
