Vacuum Cleaner Housing and Suction Switching for Easier Steering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vacuum cleaners face difficulties in smoothly changing direction, particularly in rotating left and right, and in efficiently transmitting suction force to either the head unit or a detachable pipe module.
Innovation Solution
The vacuum cleaner design incorporates a wheel assembly with rotatable housings and a channel converter system that allows for smooth directional changes and selective transmission of suction force to either the head unit or the pipe module, enabling easier maneuverability and versatile cleaning modes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the vacuum cleaner uses a conventional fixed structure, then the structure is simple, but the maneuverability and ease of changing direction deteriorates
Solution Approach 1:
The vacuum cleaner body is divided into multiple rotatable housing sections (first housing, second housing, third housing) that can rotate relative to each other, allowing independent directional control of different segments to improve maneuverability
Solution Approach 2:
The housings are designed to be dynamically rotatable rather than fixed, enabling the vacuum cleaner to change direction smoothly by rotating the housings left or right, transforming the static structure into a dynamic, adaptable system
2Adaptability or versatility
If the vacuum cleaner has a fixed suction channel, then the structure is simple, but the adaptability to different cleaning configurations deteriorates
Solution Approach 1:
The suction channel is designed as a dynamic system with a movable partition wall that can switch between different positions, allowing the suction force to be transmitted to either the head unit or the pipe module depending on the cleaning configuration
Solution Approach 2:
The partition wall acts as an intermediary element within the suction channel, controlling the flow path of suction force by moving between different positions to direct airflow to the appropriate cleaning component

AI summary
A vacuum cleaner that includes an upright main body, an upright fan motor generating a suction force, and a wheel assembly that is mounted on the upright main body and guides movement and rotation of the upright main body. The upright main body includes a first housing that is installed on the wheel assembly so as to be rotatable in a leftward/rightward direction, and a second housing that is installed in the first housing so as to be rotatable in a forward/backward direction. The vacuum cleaner can be moved and rotated by freely moving an extension frame extending upward from the second housing in forward, backward, leftward, and rightward directions.
