Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional portable charging devices lack the ability to securely manage and limit power distribution to specific users, and they require utility power to function, limiting charging convenience and customer management for service providers.
Innovation Solution
A wireless power supply system comprising a management server, a terminal charging device, and a power storage device that uses electromagnetic waves for contactless charging, with identification management to ensure secure and convenient power distribution to authorized users.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a portable charging device supplies electric energy wirelessly to multiple users, then charging convenience is improved, but the ability to limit power distribution to specific customers is lost
Solution Approach 1:
A management server is introduced as an intermediary between the portable charging device and users. The server receives identification information from users, determines whether to permit charging, and communicates decisions back to the charging device. This mediator enables both wireless convenience and selective customer management without requiring direct complex interaction between the charging device and each user.
2Reliability
If a portable charging device requires utility power connection, then power supply stability is improved, but charging availability in locations without utility power deteriorates
Solution Approach 1:
The patent replaces the mechanical connection system (power supply cord and outlet) with a wireless electromagnetic energy transmission system. The portable charging device transmits electric energy through electromagnetic waves to the battery charger, eliminating the need for physical connection to utility power outlets and enabling charging in locations without fixed power infrastructure.
3Adaptability or versatility
If identification verification is implemented, then customer management capability is improved, but system complexity increases
Solution Approach 1:
The system is segmented into distinct functional modules: a portable charging device for wireless power transmission, a battery charger for receiving and storing energy, and a management server for handling identification verification. This segmentation distributes complexity across separate components, allowing each to perform its specific function independently while maintaining overall system manageability.
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
Enables secure and convenient charging of portable electronic devices without the need for utility power, allowing service providers to manage customer information and billing effectively while ensuring only authorized users receive power.
Implementation Method 1
a power storage device that is charged by the terminal charging device without contact... an antenna which communicates with the power storage device and transmits electric power to the power storage device... an antenna which receives electromagnetic waves that are transmitted from the terminal charging device
Implementation Method 2
a power storage portion which stores the electromagnetic waves that are received by the antenna as electric power

AI summary
An object is to provide a system for improving convenience for users, by which a portable electronic device or the like can be charged even in a place where utility power is not available. Another object is to provide a system which allows a service provider to easily perform customer management. A wireless power supply system includes a power storage device having a power storage portion, a terminal charging device for wirelessly supplying electric power to the power storage device, and a management server having user information. Electric power can be supplied to specified users by intercommunication of user information between the power storage device and the terminal charging device and between the terminal charging device and the management server.
