Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If individual battery devices are used for auxiliary devices, then each device can operate independently, but charging becomes inconvenient as each device needs to be connected to a power source separately
Solution Approach 1:
The patent combines multiple battery devices into a single integrated battery device with a shared power source. The battery device includes a battery pack, control circuit, and wireless communication module that can charge multiple auxiliary devices simultaneously through magnetic attraction connection, eliminating the need for separate charging connections for each device.
Solution Approach 2:
The battery device is designed with universal charging capability that can serve multiple auxiliary devices simultaneously. The power supply connector can magnetically attract and charge different types of charging connectors (first, second, third charging connectors) through the same power source and control circuit, making the system multi-functional.
2Ease of operation
If detachable charging connectors are used, then the auxiliary device can be easily mounted and removed, but reliable power transfer and connection stability become challenging
Solution Approach 1:
The patent replaces traditional mechanical connection systems with magnetic attraction for connecting charging connectors. The power supply connector and charging connectors use magnetic fields to achieve automatic alignment and secure connection, eliminating the need for precise manual alignment while ensuring reliable electrical contact through the magnetic force.
Solution Approach 2:
The patent introduces a control circuit as an intermediary between the battery pack and charging connectors. The control circuit manages power distribution, monitors charging status, and ensures reliable power transfer by controlling the power supply to multiple charging connectors simultaneously, maintaining connection stability even with detachable design.

AI summary
An auxiliary assembly includes an auxiliary device and a battery device. The auxiliary device includes a charging connector and a passive magnetic attraction component. The battery device includes a power supply connector, an active magnetic attraction component, and a management module. The charging connector is detachably mounted on a mounting rail of the power supply connector, so to move between a power supply position and a detachment position. When the charging connector is located at the power supply position, the passive magnetic attraction component can be magnetically attracted by the active magnetic attraction component. When the charging connector is located at the detachment position, the passive magnetic attraction component can be detached from the active magnetic attraction component. The management module controls the active magnetic attraction component to perform a magnetic action on the passive magnetic attraction component, so that the power supply connector charges the charging connector.
