Auto-eject connector mechanism for charging cord disconnection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing smartphone charging devices do not automatically disconnect the charging cable from the smartphone once the battery is fully charged, leading to reduced battery life due to overcharging and inconvenience in carrying and managing charging cables.
Innovation Solution
An auto-eject apparatus with a connector that uses a software program to detect a substantially charged battery, triggering two pins to mechanically eject the charging cord's proximal end from the communication device, featuring a processor component, linkage assembly, and a USB Type-C charging cord for automatic disconnection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the charging cable remains connected after full charge, then the battery may be overcharged, but the battery life is significantly reduced
Solution Approach 1:
The system performs preliminary detection of battery charge status through software monitoring, and triggers the eject mechanism before overcharging can occur. The processor continuously monitors battery parameters and activates the pin mechanism as soon as full charge is detected, preventing the harmful effect of overcharging.
Solution Approach 2:
The system implements feedback control by continuously monitoring battery charge status and using this information to control the eject mechanism. The software program reads battery status in real-time and provides feedback to the processor, which automatically triggers disconnection when the battery is full, creating a closed-loop control system that prevents overcharging.
2Ease of operation
If manual disconnection of charging cable is required, then the charging process can be controlled, but the ease of operation is reduced
Solution Approach 1:
The system performs self-service by automatically monitoring its own battery status and triggering the disconnection mechanism without user intervention. The software program continuously checks battery charge level and autonomously activates the pin mechanism to eject the connector, making the device serve itself and eliminating the need for manual operation.
Solution Approach 2:
The patent replaces manual mechanical disconnection with an automated system combining software monitoring and mechanical actuation. Instead of requiring user hand operations to disconnect the cable, the system uses software to detect charge status and triggers a pin mechanism for automatic physical disconnection, substituting human action with automated control.
3Ease of operation
If long charging cables are used, then charging outlets are more accessible, but the convenience of carrying and managing cables is reduced
Solution Approach 1:
The system extracts the need for long cables by providing automatic disconnection functionality. Users can charge at various locations and automatically disconnect when full, eliminating the need to carry long cables to access different charging outlets. The automatic eject feature allows users to leave the device at any outlet without worrying about cable management or carrying long cables.

AI summary
An auto-eject apparatus for ejecting a charging cord from a communication device after the battery is substantially charged. The auto-eject apparatus serves to provides a connector that ejects a proximal end of a charging cord that is attached to a communication device after the battery of the communication device is substantially charged. A processor component operatively connects to the pins. The processor component runs a software program that detects when the battery is finished charging. The software program may be a battery monitoring program. After detecting a full charge, the software program triggers two pins in the apparatus to mechanically eject the proximal end of the charging cord. The pins axially extend and retract in relation to the housing, such that axially extending the pins urges the connector to disengage from the communication device A linkage assembly articulates between the processor component and the pins to axially displace the pins.
