Solution Overview
Problem
Conventional vacuum cleaners face economic issues due to the need for multiple brushes covering the entire outer surface of rollers, which increases size and complexity, making it difficult to clean small spaces effectively.
Innovation Solution
A cleaner design featuring a brush assembly with a brush bar that moves translational motion via a rotating member, link, connecting member, and guide rail system, allowing the brush to sweep dust efficiently with fewer brushes and a reduced suction device height.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If brushes are installed over the entire outer circumferential surface of the roller to clean protrusion portions and corner portions, then cleaning capability is improved, but the number of brushes increases and economic cost increases
Solution Approach 1:
The brush assembly is segmented into a rotating brush portion and a translational moving portion. Only a partial brush assembly is installed on the roller, while the rest of the cleaning function is achieved through the translational motion of the brush assembly guided by the guide rail, eliminating the need to cover the entire roller circumference with brushes
Solution Approach 2:
The brush assembly is made dynamically movable along the guide rail through the link mechanism connected to the rotating member. This dynamic translational motion allows the brush to reach protrusion portions and corner portions without requiring brushes to be installed all around the roller, reducing the number of brushes needed
2Adaptability or versatility
If a roller-type brush assembly is used to clean protrusion portions and corner portions, then cleaning versatility is improved, but the size of the suction device increases
Solution Approach 1:
The brush assembly transitions from a fixed roller-type structure to a dynamic translational structure guided by the guide rail. This allows the brush to extend and reach protrusion portions and corner portions without requiring a large roller assembly, thereby maintaining a compact suction device size while preserving cleaning versatility
Solution Approach 2:
The brush assembly moves from rotational motion only to translational motion along the guide rail, adding a linear dimension to the cleaning action. This enables the brush to access protrusion portions and corner portions without increasing the radial size of the suction device, as the extended reach is achieved through linear displacement rather than rotational radius
3Productivity
If multiple brushes are installed to increase cleaning area, then cleaning efficiency is improved, but device complexity and cost increase
Solution Approach 1:
Instead of using multiple static brushes arranged around the roller, the invention employs a single brush assembly that dynamically translates along the guide rail to cover multiple cleaning zones. This dynamic approach achieves comprehensive cleaning coverage with fewer brushes, reducing device complexity while maintaining high cleaning efficiency
Solution Approach 2:
The brush assembly serves multiple functions: it rotates to agitate dust, translates along the guide rail to reach protrusion portions and corner portions, and can be positioned at different locations during operation. This multi-functionality allows a single brush assembly to perform the work of multiple brushes, improving cleaning efficiency without increasing device complexity
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
This design enhances cleaning efficiency with fewer brushes, increases the cleaning area, and reduces the suction device height, enabling effective cleaning in smaller spaces while minimizing the number of brushes and maintaining a compact form.
Implementation Method 1
an operating assembly for transmitting power of the motor to the brush assembly to perform translational movement
Implementation Method 2
a guide rail into which the protrusion is inserted. Accordingly, the protrusion is inserted into the guide rail to perform a sliding motion, and accordingly the connecting member and the brush unit perform translational motion
