Information Notifying Device for Transportation Battery Charging Timing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Passengers using external devices like smartphones on transportation equipment face challenges in determining the optimal timing to charge their devices before arrival at the destination, risking battery depletion due to insufficient charging time.
Innovation Solution
An information notifying device with a first communication circuit for receiving estimated arrival time, a second communication circuit for monitoring battery capacity, and a controller that calculates the necessary charging time and prompts users to charge their devices at the appropriate time based on these inputs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If passengers use external devices during transportation, then they can enjoy entertainment and productivity, but the battery capacity decreases and may be depleted before arrival
Solution Approach 1:
The notification device performs preliminary action by calculating the required charging time in advance and notifying passengers before the battery is depleted, allowing them to charge their devices proactively during the transportation journey
2Quantity of substance
If passengers charge their devices continuously, then battery capacity is maintained, but they may miss the optimal charging window before arrival
Solution Approach 1:
The notification device implements feedback by continuously monitoring battery capacity information from external devices, calculating the required charging time, and providing timely notifications to passengers about the optimal charging window, enabling them to make informed decisions about when to charge
Solution Approach 2:
The system calculates the required charging time in advance based on current battery capacity and estimated arrival time, notifying passengers beforehand to charge their devices during the optimal window before depletion occurs
3Loss of information
If the notification system provides detailed charging information, then passengers can make informed decisions, but the system complexity increases
Solution Approach 1:
The notification device extracts only the essential charging information (required charging time and optimal timing) from the complex data set of battery parameters and transportation schedule, presenting it in a simple, actionable format to passengers without overwhelming them with unnecessary details

AI summary
An information notifying device in accordance with the present disclosure includes a first communication circuit, a second communication circuit, a clock, and a controller. The first communication circuit receives first information regarding an estimated arrival time at which transportation equipment will arrive at a destination. The second communication circuit receives second information regarding a remaining battery capacity of a battery installed in an external device. The clock keeps a current time. The controller calculates a first charging time necessary to charge the external device to a fully charged state based on the second information, and outputs information prompting to charge the external device at a first timing based on the first information, the current time and the first charging time.
