Power sharing vacuum cleaner assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Cordless vacuum cleaners with a single power source quickly deplete charge when using accessories like powerheads, as both the suction path and accessory require power, leading to reduced operational time.
Innovation Solution
A power sharing vacuum cleaner assembly with a vacuum body and accessory each having separate power sources that can share power with each other, allowing power to be transferred between the first power source for the suction path and the second power source for the accessory, extending the operational time by using a charging stand to recharge both sources independently or simultaneously.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single power source is used in the vacuum cleaner, then the device complexity is reduced, but the operational time is quickly depleted when both the suction path and accessory require power
Solution Approach 1:
The power source system is segmented into multiple independent power sources - a first power source in the vacuum body and a second power source in the accessory. Each power source independently powers its respective component, allowing simultaneous operation without rapid charge depletion. This segmentation resolves the contradiction by distributing power demands across separate sources while maintaining overall system simplicity through modular design.
2Duration of action of moving object
If separate power sources are used in the vacuum body and accessory, then the operational time is extended through power sharing, but the device complexity increases
Solution Approach 1:
The first and second power sources are merged into a single integrated power system with shared charging capability. The power sources can charge independently or simultaneously through a unified charging interface, and power can be transferred between them when needed. This merging approach extends operational time while managing complexity through integration and standardization of the power management architecture.
3Loss of time
If both the vacuum body and accessory are charged simultaneously through a charging stand, then the charging time is reduced, but the charging system complexity increases
Solution Approach 1:
The charging stand is designed with universal multi-functionality to accommodate and charge both the vacuum body and accessory simultaneously through a single device. The stand incorporates multiple charging interfaces and power distribution capabilities that can independently or concurrently charge different components. This multi-functional design reduces total charging time while managing system complexity through standardized charging architecture and integrated power management.

AI summary
A vacuum cleaner assembly basically includes a vacuum body, a first power source, an accessory, and a second power source. The first power source is configured to create flow through a suction path. The accessory is configured to be removably connected to the vacuum body. The second power source is configured to power the accessory. Each of the first and second power sources is configured to share power with the other of the first and second power sources.
