Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the battery is designed in a non-detachable mode, then the battery structure strength is improved, but the internal connection structure becomes fragile and prone to damage during detachment
Solution Approach 1:
The detection module performs preliminary detection of the battery connection status before detachment occurs. By outputting identification information through the connector, the system proactively identifies whether the battery is properly connected, allowing the control module to prevent detachment operations before they can cause damage to the fragile internal connection structure.
Solution Approach 2:
The detection module provides real-time feedback about the battery connection status to the control module. The control module uses this feedback information to make informed decisions about whether to allow detachment, thereby protecting the fragile internal connection structure from damage that would occur during improper detachment attempts.
2Ease of operation
If the battery is designed in a detachable mode, then the ease of operation is improved, but the connector becomes prone to short circuit and damage
Solution Approach 1:
Before allowing battery detachment, the detection module performs a preliminary check by outputting identification information through the connector. The control module receives and verifies this information to confirm proper connection status, thereby preventing detachment operations that could lead to connector short circuits or damage.
Solution Approach 2:
The detection module provides feedback about the connector's connection status to the control module. This feedback mechanism enables the control module to verify that the connector is properly engaged before allowing detachment, reducing the risk of short circuits and damage while maintaining ease of operation for legitimate detachment scenarios.
3Reliability
If a detection module is added to detect battery connection status, then the safety is improved, but the device complexity increases
Solution Approach 1:
The detection module is integrated with the existing connector structure, merging the detection function into the connection interface itself. The detection module outputs identification information through the same connector that provides electrical connection, eliminating the need for separate detection hardware and reducing overall system complexity while maintaining safety.
Solution Approach 2:
The connector serves multiple functions: it provides electrical connection for power and data transmission, and simultaneously serves as the output path for identification information from the detection module. This multi-functionality reduces the need for additional components, thereby improving safety without significantly increasing device complexity.

AI summary
This application discloses a battery assembly and a battery detection system and method. The system includes a battery assembly and an electronic device. The battery assembly includes a first connector and a detection module connected to the first connector. The electronic device includes a second connector and a control module connected to the second connector. When the first connector is connected to the second connector, the detection module is configured to output first identification information to the electronic device through the first connector. When the second connector receives the first identification information, the control module confirms that the battery assembly is in a connected state. After the first connector is disconnected from the second connector, the detection module generates and outputs second identification information. When information received by the second connector changes from the first identification information to the second identification information, the control module confirms that the battery assembly is disconnected. The battery detection system according to embodiments of this application can identify detachment of a battery and ensure safety of the battery and the electronic device in use.
