Smartphone Charging Security via Induction and Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Portable electronic devices with touch-screen displays face the issue of being taken away by others while charging, as public chargers do not provide secure authentication mechanisms, allowing unauthorized access to the device's functions.
Innovation Solution
Incorporating a power receiving unit for electromagnetic induction charging, a control unit that restricts device functions when separated from a predetermined charger, and a notification system to alert the user of unauthorized separation, enabling authentication to restore functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a portable electronic device is charged by being placed on a battery charger provided in a public place, then the device can be charged without electric contact, but the device may be taken away by another person
Solution Approach 1:
The control unit performs preliminary authentication verification before enabling full device functions during charging. When the device is detected to be separated from the charger, the control unit restricts execution of predetermined functions and requires authentication operation first, preventing unauthorized use before it can occur
Solution Approach 2:
The control unit acts as an intermediary between the charging system and device functions. It monitors the charging state and mediates function execution by restricting or enabling functions based on authentication status, creating a security layer between the physical device and its operational capabilities
2Reliability
If the device restricts functions when separated from the charger, then unauthorized use is prevented, but the user experience is degraded
Solution Approach 1:
The system dynamically adjusts device functionality based on real-time charging status. When charged, full functions are available; when separated, functions are restricted. This dynamic adaptation allows the system to maintain security while providing optimal user experience under different conditions
Solution Approach 2:
The control unit continuously monitors charging state and provides feedback by adjusting function availability. When separation is detected, the system feedbacks a restricted state requiring authentication. This closed-loop feedback mechanism ensures security while guiding users through the authentication process to restore full functionality
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Prevents unauthorized use of the device by restricting functions until proper authentication is performed, ensuring secure charging and reducing the risk of theft.

AI summary
An object of the present invention is to provide a portable electronic device, a method, and a computer-readable recording medium, all of which are capable of preventing the portable electronic device from being taken away by another person while charging. The smartphone includes: a touch-screen display; a power receiving unit that receives power from electromagnetic waves that are supplied from a battery charger; and a controller that restricts execution of predetermined functions in a case in which the portable electronic device is separated from the battery charger in a state where the battery charger is supplying electromagnetic waves to the power receiving unit, and enables the predetermined functions to be executed in a case in which an authentication operation is performed via the touch-screen display after restricting execution of the predetermined functions.
