Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vacuum cleaner charging systems can only charge one battery pack at a time, limiting user experience and requiring separate charging times for the vacuum cleaner and its battery pack.
Innovation Solution
A charger with multiple interfaces and a controlling module that identifies and charges both the vacuum cleaner and its battery pack simultaneously, using rectification and voltage conversion to optimize charging based on temperature and voltage parameters.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single charging interface is used for the vacuum cleaner, then the charging system is simple, but the battery pack cannot be charged separately and charging time increases
Solution Approach 1:
The charger is designed with multiple charging interfaces including a first charging interface for the vacuum cleaner and a second charging interface for the battery pack, allowing the same charger to perform multiple charging functions simultaneously or separately, thus improving adaptability without significantly increasing complexity
Solution Approach 2:
The charging system is segmented into separate charging interfaces and controlling modules for different devices (vacuum cleaner and battery pack), allowing independent charging control for each device while using a unified charger structure
2Productivity
If the whole machine is charged by a wall-type adapter, then the charging system is simple, but charging and usage cannot be done in parallel
Solution Approach 1:
The battery pack can be charged separately in advance using the second charging interface before it is needed for the vacuum cleaner, allowing the user to prepare the battery pack ahead of time and avoid waiting during usage, thus improving both charging efficiency and user convenience
3Loss of time
If fast charging is implemented, then charging time is reduced, but temperature control and safety management become more difficult
Solution Approach 1:
The charging controlling modules continuously monitor charging parameters including temperature, voltage, and current, and dynamically adjust the charging current based on real-time feedback to maintain safe operating conditions while enabling fast charging, thus reducing charging time without compromising safety
Solution Approach 2:
The charging system uses dynamic charging control where the charging current is adjusted in real-time based on battery state, temperature conditions, and charging stage, allowing the system to optimize charging speed while maintaining safety through continuous adaptation rather than fixed charging parameters

AI summary
A charger for a vacuum cleaner and a fast charging controlling method thereof are provided. The charger includes: a plurality of first charging interfaces; a rectifying module configured to rectify an alternating current to output a direct current; a plurality of charging controlling modules each connected between an output end of the rectifying module and a first charging interface correspondingly; and a main controlling module configured to communicate with each of the first charging interfaces respectively to identify whether any first charging interface is connected with a device to be charged (i.e., a battery pack to be charged and/or the vacuum cleaner to be charged), acquire a parameter of the device to be charged if identifying that a first charging interface is connected with the device to be charged, and perform charging control on the device to be charged through a charging controlling module corresponding to the first charging interface according to the parameter of the device to be charged. Thus, charging requirements of different types of devices to be charged, such as the vacuum cleaner and the battery pack can be realized, thereby improving user experience.
