Battery Connector Detection for Safe Non-Detachable Battery Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Non-detachable batteries in electronic devices are prone to damage and short-circuiting during detachment due to their fragile internal connection structures, posing safety risks for both the battery and the device.
Innovation Solution
A battery detection system comprising a first connector and a detection module connected to an electronic device's second connector, which outputs identification information to confirm connection and disconnection states, ensuring safe detachment by locking the identification signal when the battery is disconnected.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a non-detachable battery is designed with a fragile internal connection structure, then the battery can be integrated into the electronic device, but the battery is very likely to damage and the connector is very likely to be short-circuited during detachment
Solution Approach 1:
The detection module detects the connection status of the battery connector before detachment operations are performed. The control module receives the detection signal and determines whether to allow detachment based on the detected state, preventing premature or unsafe detachment actions that could damage the fragile internal connection structure
Solution Approach 2:
The detection module continuously monitors the connection status of the battery connector and provides real-time feedback signals to the control module. This feedback mechanism enables the system to respond to connection changes and prevent operations that would compromise battery safety during detachment
2Strength
If the battery structure is of relatively low strength, then the battery can be made compact and lightweight, but the battery is very likely to damage during detachment if not performed by a professional
Solution Approach 1:
Before any detachment operation, the detection module performs a preliminary check of the battery connector's connection status. The control module uses this information to determine whether the battery is in a state suitable for detachment, preventing operations that could damage the low-strength battery structure
Solution Approach 2:
The detection module automatically monitors and reports the connection status of the battery connector without requiring manual intervention. The control module autonomously determines whether detachment conditions are met, reducing the need for professional assessment and minimizing the risk of damage during user-performed detachment
3Reliability
If a detection module is added to detect connection status, then the safety of the battery and electronic device is ensured, but the device complexity increases
Solution Approach 1:
The detection module is integrated with the existing battery connector structure, combining the detection function with the connection interface. This merging approach allows connection status detection to be implemented without adding separate, complex detection systems, thereby ensuring safety while minimizing the increase in device complexity

AI summary
A battery detection 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.
