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 for maintaining suction integrity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If the extension pipe is made longer to reach lower spaces, then cleaning capability is improved, but storage difficulty increases
Solution Approach 1:
The extension pipe is divided into a first extension pipe and a second extension pipe that can be separately stored. The first extension pipe connects to the suction portion while the second extension pipe connects to the cleaner body, allowing them to be stored in different locations or configurations, thus solving the storage difficulty of long extension pipes.
Solution Approach 2:
The second extension pipe is configured to rotate relative to the first extension pipe, adding rotational freedom in a new dimension. This allows the extension pipe system to reach lower spaces by rotating downward while maintaining a compact storage configuration when folded.
2Length of moving object
If the extension pipe is made longer to reach lower spaces, then cleaning capability is improved, but user comfort deteriorates
Solution Approach 1:
The second extension pipe rotates relative to the first extension pipe, enabling the suction portion to reach lower spaces without requiring the user to bend their waist. The rotational mechanism allows the user to maintain an upright posture while the extension pipe extends downward to clean under furniture.
3Adaptability or versatility
If the extension pipe structure is made more complex to enable rotation, then adaptability is improved, but device complexity increases
Solution Approach 1:
The extension pipe is segmented into two separate pipes (first and second extension pipes) connected by a rotation joint. This segmentation allows each pipe to be simpler in structure while the connection point provides the rotational functionality, achieving adaptability without excessive complexity in any single component.

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.
