Vacuum Cleaner Extension Holder for Multi-Unit Storage Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vacuum cleaners with multiple suction units face storage challenges due to the need for separate spaces, leading to instability and limited capacity, as well as potential tilting and separation of accessories during operation.
Innovation Solution
A cleaning apparatus featuring an extension holder that allows multiple suction units to be coupled and stored efficiently, with a design that maintains a neat appearance and stable storage by positioning the center of gravity below the auxiliary battery, minimizing the risk of overturning and enabling easy coupling and decoupling of units.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If multiple suction units are stored in a holder fixed to the vacuum cleaner or stand, then the suction units can be stored, but the holder may tilt or separate during operation due to center of gravity changes
Solution Approach 1:
The holder is designed to extend in both horizontal and vertical directions, utilizing three-dimensional space efficiently. This allows multiple suction units to be stored while maintaining the center of gravity within the stand's support area, preventing tilting during operation.
2Quantity of substance
If a holder is fixed to the vacuum cleaner or stand to store accessories, then storage is enabled, but the number of accessories that can be stored is limited
Solution Approach 1:
The holder is segmented into multiple coupling portions positioned at different locations and orientations. Each coupling portion can independently hold a suction unit, allowing the system to store multiple accessories without requiring a single complex structure.
Solution Approach 2:
The holder is designed with universal coupling portions that can accommodate various types of suction units with different shapes and sizes. This multi-functional design allows the same holder structure to store different accessories without modification.
3Quantity of substance
If accessories are stored in a holder fixed to the vacuum cleaner, then storage is provided, but the accessories may move or separate during operation
Solution Approach 1:
The holder acts as an intermediary structure between the stand and the suction units. It provides a stable mounting platform with multiple coupling portions that securely retain suction units, preventing them from moving or separating during vacuum cleaner operation.

AI summary
A cleaning apparatus includes a vacuum cleaner, a stand, a first coupling portion, a plurality of suction units, and an extension holder. The vacuum cleaner includes a main body configured to receive and discharge air. The vacuum cleaner is mounted in the stand. The first coupling portion is formed in the stand and is positioned behind the vacuum cleaner. One of the suction units is selectively coupled to an air inlet through which air is suctioned into the main body. A first connector coupled to the first coupling portion is located at one end of each of the suction units. The extension holder includes a second connector and second coupling portions. The second connector is coupled to the first coupling portion. The second coupling portions are respectively positioned on either side of the second connector.
