Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vacuum cleaners require users to bend to clean lower spaces, causing discomfort and have cumbersome extension pipes that are difficult to store.
Innovation Solution
A vacuum cleaner with a rotatable extension pipe system, including a first and second extension pipe that can be arranged in multiple configurations to facilitate cleaning and storage, featuring a link assembly with a locking device to manage the rotation and a flexible hose to maintain suction force.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the extension pipe is made longer to reach lower spaces, then cleaning accessibility is improved, but storage difficulty increases
Solution Approach 1:
The extension pipe is divided into two separate pipes (first extension pipe and second extension pipe) that can be independently arranged. This segmentation allows the pipes to be folded into a compact configuration for easy storage while maintaining sufficient length for reaching lower spaces during cleaning operations.
Solution Approach 2:
The extension pipes are designed to be rotatable relative to each other, transforming from a static long pipe into a dynamic structure that can change its configuration. When not in use, the pipes can be rotated to face each other and folded compactly; during use, they can be extended and positioned as needed for accessing lower spaces.
2Ease of operation
If the extension pipe is made longer to reach lower spaces, then user convenience is improved, but the pipe becomes cumbersome
Solution Approach 1:
By dividing the long extension pipe into two manageable segments (first and second extension pipes), the overall structure becomes less cumbersome while still providing the necessary reach. Each segment is more manageable individually, reducing the burden on the user during operation.
Solution Approach 2:
The rotatable connection between the two extension pipes creates a dynamic structure that can adapt its shape and configuration. This flexibility reduces the cumbersome nature of a long rigid pipe, allowing it to be maneuvered more easily and stored in a compact form when not in use.
3Volume of stationary object
If the extension pipe is folded for storage, then storage space is reduced, but suction force may be compromised
Solution Approach 1:
The extension pipes incorporate flexible elements that allow the pipes to be folded and bent for compact storage without compromising the integrity of the air passage. The flexible structure maintains proper airflow alignment even when folded, ensuring suction force is preserved when the cleaner is stored in a compact configuration.

AI summary
A cleaner includes a first extension pipe connected to a suction portion contacting a surface to be cleaned, and a second extension pipe coupled to a cleaner body having a driver generating suction force, and rotatably coupled to the first extension pipe. The first and second extension pipes operate in a first arrangement configured to allow the second extension pipe to be arranged in a longitudinal direction of the first extension pipe, and a second arrangement configured to allow the second extension pipe to rotate in a first direction from the first arrangement such that the first extension pipe and the second extension pipe are arranged to face each other. Such configuration enables a user to increase cleaning efficiency.
