Wireless Charging Receiver Display for Stop-Reason Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users of wireless charging devices are often unaware of the reason for a disruption in charging, leading to dissatisfaction due to the lack of feedback, as conventional systems do not provide clear reasons for stopping wireless charging.
Innovation Solution
An electronic device equipped with a processor and display that receives data on reasons for stopping wireless charging from an external device, transmits acknowledge data, and displays the reason, allowing users to understand the cause of the interruption and improving the usability of wireless charging.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wireless charging is performed without providing stop reasons to users, then the charging process is simple and device complexity is low, but user satisfaction deteriorates due to lack of feedback when charging stops
Solution Approach 1:
The patent implements a feedback mechanism where the power transmitter detects reasons for stopping wireless charging (such as foreign objects, overheating, or complete power transfer) and transmits these reasons to the power receiver, which then displays them to the user. This feedback loop resolves the contradiction by providing users with clear information about why charging stopped, thereby improving user satisfaction without significantly increasing device complexity through the use of existing communication and display components.
2Reliability
If the power transmitter immediately stops power transfer when a disruption is detected, then the safety and reliability of wireless charging is improved, but the user experience deteriorates because the user is not informed of the reason
Solution Approach 1:
The patent applies preliminary action by having the power transmitter detect and identify the reason for stopping wireless charging before actually stopping the power transfer. The system prepares the stop reason information and transmits it to the power receiver in advance, so that when the charging stops, the user is already informed of the cause. This resolves the contradiction by maintaining safety through immediate stopping while improving user experience through advance notification of the reason.
3Speed
If wireless charging stops due to disruptions without notification, then the response time to safety issues is fast, but information completeness deteriorates as users lack knowledge of the charging status
Solution Approach 1:
The patent implements a feedback mechanism where the power transmitter detects reasons for stopping wireless charging (such as foreign objects, overheating, or complete power transfer) and transmits these reasons to the power receiver, which then displays them to the user. This feedback loop resolves the contradiction by providing users with clear information about why charging stopped, thereby improving user satisfaction without significantly increasing device complexity through the use of existing communication and display components.
Applied Scientific Principles

Function Achieved in This Case
Provides users with clear feedback on why wireless charging has stopped, enhancing user satisfaction and improving the quality and usability of the charging process by offering insights into potential issues.
Implementation Method 1
wireless charging techniques based on electromagnetic induction or magnetic resonance have been applied to electronic devices such as smart phones. When a power receiver (or a 'PRX,' e.g., a smart phone) comes in contact with a power transmitter (or 'PTX,' e.g., a wireless charging pad) or is within a certain distance of the power transmitter, the battery of the power receiver can be charged due to the electromagnetic induction or magnetic resonance between the transmission coil of the power transmitter and the reception coil of the power receiver.
Implementation Method 2
wireless charging techniques based on electromagnetic induction or magnetic resonance have been applied to electronic devices such as smart phones. When a power receiver (or a 'PRX,' e.g., a smart phone) comes in contact with a power transmitter (or 'PTX,' e.g., a wireless charging pad) or is within a certain distance of the power transmitter, the battery of the power receiver can be charged due to the electromagnetic induction or magnetic resonance between the transmission coil of the power transmitter and the reception coil of the power receiver.

AI summary
An electronic device may include a display, a power reception circuit, and a processor. The processor may perform wireless charging by receiving power wirelessly from an external electronic device through the power reception circuit, and receive data on one or more reasons to stop wireless charging from the external electronic device during the wireless charging. Also, the processor may transmit acknowledge (ACK) data to the external electronic device in response to receiving the data on the one or more reasons to stop wireless charging, and display, through the display, at least one reason to stop wireless charging included in the data on the one or more reasons to stop wireless charging. Other embodiments are possible.
