Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vacuum cleaner stands are prone to toppling and are difficult to fold, occupying significant space during transportation and storage.
Innovation Solution
A foldable vacuum cleaner stand with a base and support frame body, featuring a retaining frame, support plates, and a rotatable support frame that forms a triangular structure with the base, incorporating limit rods and springs for stability and ease of folding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the support frame is arranged at 90 degrees relative to the base, then the structure is simple, but the center of gravity is high and stability is poor
Solution Approach 1:
The support frame is designed with an inclined structure rather than a vertical 90-degree arrangement. The support frame body forms an acute angle with the base, creating an asymmetric configuration that lowers the center of gravity and improves stability while maintaining structural simplicity
Solution Approach 2:
The patent introduces a triangular structural configuration by positioning the support frame at an incline relative to the base, creating a stable triangular support structure that distributes weight more effectively and lowers the center of gravity compared to a vertical arrangement
2Volume of stationary object
If the vacuum cleaner stand is designed to be foldable, then storage space is reduced, but the structural complexity increases
Solution Approach 1:
The support frame is divided into multiple segments including the support frame body, support plates, and connecting components. These segmented parts can be folded relative to each other through the inclined connection structure, enabling compact storage while maintaining structural integrity
Solution Approach 2:
The connection between the support frame body and base is designed to be dynamic and adjustable. The inclined support frame can be folded and unfolded through the articulated connection, allowing the structure to transition between extended and compact states without complex locking mechanisms
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The stand provides enhanced stability against toppling and allows for convenient folding and unfolding, reducing storage and transportation space requirements.
Implementation Method 1
springs are installed between the front and rear ends of the limit rod and the support bolts on a same side

AI summary
A foldable vacuum cleaner stand comprises a base and a support frame body, wherein the left end of the base is provided with a retaining frame for limiting the floor brush of the vacuum cleaner, and the right end of the base is provided with at least two support plates, which are fixedly installed at the front and rear sides of the base respectively; the support frame body is located above the right end of the base and extends obliquely upward in the direction of the retaining frame, while two support plates are located at the bottom of the inner side of the support frame body; and support bolts are inserted between the front and rear sides of the support frame body and the support plates on the same side.
