Vertical Cleaner Brush Head With Single-Motor Direction Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vertical cleaners are complex, costly, and difficult to use due to the need for two motors and switches, making them hard to manufacture and inconvenient for consumers, with limited control over the floor brush direction.
Innovation Solution
A cleaner design that uses a single motor to control both dust collection and rolling brush motion, featuring a rotatable motor cover and connecting tube for easy direction control, reducing manufacturing costs and user complexity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If two motors are used (one for dust collection, one for rolling brush), then the cleaner can perform dust collection and brush rotation, but the device complexity increases and manufacturing cost rises
Solution Approach 1:
The patent combines the dust collection function and rolling brush rotation function into a single motor system. The motor drives both the dust collecting container and the rolling brush through a integrated transmission mechanism, eliminating the need for separate motors and reducing overall system complexity.
Solution Approach 2:
A single motor is designed to perform multiple functions: it simultaneously controls dust collection and rolling brush rotation. The motor serves as a universal drive source for both cleaning functions, reducing the total number of components needed.
2Ease of operation
If two switches are used (one on handle, one on floor brush), then each function can be controlled independently, but the ease of operation decreases and user convenience is reduced
Solution Approach 1:
The patent merges the control functions into a single switch located on the handle. This unified control mechanism manages both dust collection and rolling brush rotation operations, eliminating the need for separate switches and simplifying the user interface.
Solution Approach 2:
A single switch is designed to control multiple functions: it simultaneously manages dust collection and rolling brush rotation. This universal control switch reduces the total number of controls needed while maintaining full functionality.
3Adaptability or versatility
If the handle cannot control floor brush direction easily, then the structure is simpler, but the adaptability decreases and use efficiency is affected
Solution Approach 1:
The patent introduces a rotatable motor cover that can change orientation relative to the brush holder. This dynamic structure allows the brush direction to be adjusted by rotating the motor cover around a first axis, enabling the handle to control floor brush direction easily while maintaining structural simplicity.
Solution Approach 2:
The patent adds rotational freedom in another dimension by allowing the connecting tube to rotate relative to the motor cover around a second axis that is perpendicular to the first axis. This two-dimensional rotational capability enhances adaptability without significantly increasing structural complexity.

AI summary
A cleaner and a vertical cleaner are provided. The cleaner includes: a body having a connecting tube; a brush holder, with a rolling brush mounted therein; a motor cover rotatably mounted onto the brush holder around a first axis, defining an accommodating space therein, and having an opening, the connecting tube being configured to connect to the opening rotatably around a second axis different from the first axis; a motor disposed in the accommodating space for driving the rolling brush to rotate relative to the brush holder around a third axis parallel to the first axis.
