Battery Chip Authentication Signal for Imitation Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The proliferation of imitation batteries poses safety risks as they are often of inferior quality, making it difficult for users to distinguish between genuine and counterfeit batteries, which can lead to damage or explosion of electronic devices.
Innovation Solution
A battery protection system that includes a rechargeable power supply and a battery chip, which generates a customized signal after powering an electronic device. This signal is transmitted through a predetermined pin, allowing the device to verify its authenticity, and if incorrect, the power supply is cut off to prevent damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If imitation batteries are produced with cheaper prices to save costs, then manufacturing cost is reduced, but battery quality and safety deteriorate
Solution Approach 1:
The patent applies preliminary action by implementing an authentication mechanism before the battery supplies power to the electronic device. The battery chip generates an authentication signal that the electronic device verifies before allowing power supply. This preliminary verification prevents low-quality imitation batteries from damaging devices while allowing genuine batteries to function normally, thus maintaining manufacturing cost benefits while ensuring quality control.
2Device complexity
If authentication signals are transmitted through power supply lines, then additional communication hardware is eliminated, but signal interference and detection difficulty increase
Solution Approach 1:
The patent uses the power supply line itself as an intermediary to transmit authentication signals. Instead of adding separate communication hardware, the authentication signal is superimposed on the power supply voltage. The electronic device detects this signal by monitoring voltage variations on the power line, thus eliminating additional communication components while enabling authentication functionality.
3Reliability
If the electronic device continuously monitors authentication signals, then battery authenticity verification is improved, but power consumption increases
Solution Approach 1:
The patent implements periodic authentication verification instead of continuous monitoring. The electronic device checks the authentication signal at specific intervals or at key moments such as when the battery is first connected or when power supply state changes. This periodic approach maintains authentication reliability while significantly reducing power consumption compared to continuous monitoring.
