Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users of portable computing devices often face the challenge of finding nearby charging stations when their batteries are low, leading to wasted time searching for available charging facilities, especially in unfamiliar locations or during urgent situations.
Innovation Solution
A system that utilizes a computing device's wireless connectivity to access a server for information on nearby charging stations, providing users with location details, charging times, and fees, allowing them to navigate directly to the nearest suitable venue and charge their devices efficiently.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If users manually search for charging stations when battery is low, then they can find charging facilities, but it wastes valuable time and reduces productivity
Solution Approach 1:
The system performs preliminary actions by automatically monitoring battery levels and proactively searching for charging stations before the battery is completely depleted. The server pre-identifies available charging stations and prepares routing information, so when the user needs charging, the location is already determined and ready for immediate navigation, eliminating manual search time.
Solution Approach 2:
The system implements continuous feedback loops where the mobile device communicates battery status to the server, which responds with charging station recommendations. The system also provides feedback on charging station availability and updates routing information in real-time, allowing dynamic adjustment of charging plans based on current battery levels and user location.
2Reliability
If users rely on general charging station information, then they can find any charging facility, but they cannot ensure the station is suitable or available
Solution Approach 1:
The server system performs multiple functions: it monitors battery levels, searches for charging stations, verifies station availability, calculates routing, and provides real-time updates. This multi-functional approach consolidates complex information processing into a single centralized system, making the solution reliable without requiring complex processing on the user's mobile device.
Solution Approach 2:
The server acts as an intermediary between the user's mobile device and the charging station network. It aggregates charging station data from multiple sources, verifies availability, and presents filtered, reliable information to the user. This intermediary layer simplifies the complexity by handling data aggregation and verification centrally, rather than requiring the user's device to process complex charging infrastructure information.
3Duration of action of moving object
If users plan charging in advance, then they can maintain device operation, but they need accurate battery consumption predictions
Solution Approach 1:
The system performs preliminary battery analysis by monitoring historical usage patterns and current consumption rates to predict remaining operating time. This preliminary estimation allows the system to proactively notify users before battery depletion and plan charging stops in advance, ensuring continuous device operation without requiring perfectly precise real-time measurements.
Data Source
AI summary
A computing device monitors the energy level of a rechargeable battery, from which the device draws operating power. Historic usage data is used to estimate the time remaining in a present operating period, such as a workday, as well as to estimate the battery level required to provide power during that period of time. A user is then presented with information regarding the status of the battery, as well as charging time and required battery level estimates. Information regarding charging stations within publically or otherwise user-accessible venues near to the present location of the computing device is accessed and presented to the user. Reservations may be made for a charging port within a selected venue, an order may be placed for goods or services available at that venue, or other actions may be performed.
