Wireless Power Receiver Unauthorized Use Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic devices using non-contact power supply technology are vulnerable to unauthorized use since they can be easily stolen and operated without cables, leading to concerns about unfair use.
Innovation Solution
A power receiving apparatus within the electronic device includes a power receiving module, acquisition module, determination module, and control module that acquires and compares identification information from the power supply apparatus, suppressing power supply if it's not from a preset, authorized source, and optionally notifies the user or external devices of unauthorized use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If non-contact power supply technology is used to enable cableless operation, then ease of operation and mobility are improved, but the device becomes vulnerable to theft and unauthorized use
Solution Approach 1:
The system performs preliminary identification verification of the power supply apparatus before allowing power transfer. The power receiving apparatus acquires identification information from the power supply apparatus and compares it with stored identification information in advance, preventing unauthorized devices from receiving power without needing physical cables for security
Solution Approach 2:
Identification information acts as an intermediary mechanism between the power supply apparatus and power receiving apparatus. This mediator enables authorized power transfer while blocking unauthorized use, maintaining the convenience of wireless operation while adding security verification
2Reliability
If identification verification is added to prevent unauthorized use, then protection against theft is improved, but device complexity increases
Solution Approach 1:
The power receiving apparatus integrates multiple functions into unified modules: the acquisition module handles both wireless power reception and identification information acquisition, while the determination module performs both verification and control functions. This multi-functionality reduces overall device complexity while maintaining security
Solution Approach 2:
The identification verification function is merged with the existing wireless power reception control logic. The acquisition module combines power reception and identification acquisition operations, and the determination module integrates verification and power control decisions, simplifying the overall system architecture

AI summary
A power receiving apparatus carried in an electronic device comprises a power receiving module configured to receive electric power supplied from a power supply apparatus in a non-contact manner; a supply module configured to supply the electric power received by the power receiving module to a power load section of the electronic device; an acquisition module configured to acquire identification information for identifying the power supply apparatus from the power supply apparatus; a determination module configured to determine whether the identification information acquired by the acquisition module is coincident with preset identification information; and a control module configured to suppress the electric power supplied to the power load section if the determination module determines that the identification information is not coincident with the preset identification information.
