Connection Detection for Battery-Powered Electronic Apparatus
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional connection detecting methods fail to accurately respond to communication from a self-powered electronic device with a battery and power switch, leading to potential communication errors during initial communication sequences, even when the connection is normal.
Innovation Solution
An electronic apparatus with a battery and a lock unit that determines its communication readiness and lock state, outputting a connection signal only when it can communicate with the host device and is in an unlock state, ensuring proper connection detection and communication initiation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the connection detecting method is implemented without checking communication readiness, then the connection detection process is simple and fast, but communication errors occur when the second electronic apparatus is powered off
Solution Approach 1:
The patent applies preliminary action by checking the power supply state and communication readiness of the second electronic apparatus before initiating the initial communication starting sequence. The processor determines whether the second apparatus can respond to communication based on its power state, and only starts the communication sequence if the apparatus is ready. This prevents communication errors while maintaining a relatively simple detection process.
2Measurement precision
If the connection detecting terminal is pulled up on the first electronic apparatus side, then the connection can be detected when the second apparatus grounds the terminal, but false communication errors occur when the second apparatus has a power switch turned off
Solution Approach 1:
The patent applies feedback by having the processor continuously monitor and determine whether the second electronic apparatus is in a state that allows it to respond to communication. Before starting the initial communication starting sequence, the processor checks if the second apparatus can respond based on its power supply state. This feedback mechanism ensures that communication is only initiated when the second apparatus is actually ready, preventing false communication errors while maintaining accurate connection detection.

AI summary
An electronic apparatus includes a battery for supplying power, a lock unit attachable to a first electronic apparatus, and a processor configured to output, after the electronic apparatus is attached to the first electronic apparatus, a connection signal to the first electronic apparatus indicating that the electronic apparatus has been attached to the first electronic apparatus. The processor is configured to determine, based on information about a state of the battery, whether the electronic apparatus can receive communication with the first electronic apparatus, determine whether the lock unit is in a lock state for locking a connection of the electronic apparatus to the first electronic apparatus or in an unlock state for unlocking the connection, and output the connection signal in a case where the electronic apparatus can receive the communication with the first electronic apparatus and the lock unit is in the unlock state.
