Vacuum Cleaner Vibration Plate Layout for Ergonomic Bedding Cleaning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional bedding cleaners require users to bend for extended periods, leading to discomfort and inefficiency due to their design, which affects the cleaning effectiveness and increases cleaning time, while also having complex structures that reduce durability and increase noise.
Innovation Solution
A vacuum cleaner design with a vibration system that includes a motor with an eccentric load to produce vibration, transferring this vibration to two plates via a connection member, allowing for closer contact with the ground and enhanced cleaning efficiency, while also simplifying the structure and reducing noise through a smoother air flow path.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the handle position is raised to increase cleaner height, then user comfort is improved, but the upper body becomes elongated and the overall appearance becomes less elegant
Solution Approach 1:
The handle is nested within the upper body structure rather than being a separate component. The handle is positioned at the rear end of the upper body, integrating it into the overall design, which maintains a compact and elegant appearance while providing ergonomic handling for the user.
2Ease of operation
If the cleaner height is increased, then user comfort is improved, but the entire size increases resulting in inconvenience in handling and storing
Solution Approach 1:
The handle is integrated into the upper body structure, nesting the handling function within the existing body framework. This integration allows the cleaner to maintain a compact overall size for easy handling and storage while still providing an ergonomically positioned handle for user comfort during operation.
3Device complexity
If the lower body and nozzle body are horizontally arranged, then the structure is simple, but the cleaning area is limited and cleaning time increases
Solution Approach 1:
The cleaner transitions from a two-dimensional horizontal arrangement to a three-dimensional configuration by inclining the upper body rearward. This dimensional change allows the suction nozzle to contact the ground while the upper body extends backward, expanding the effective cleaning area and improving productivity without significantly increasing structural complexity.
4Device complexity
If the air flow path is curved multiple times, then the dust container and fan motor can be accommodated, but air resistance increases and cleaning efficiency decreases
Solution Approach 1:
The air flow path utilizes the three-dimensional space created by the inclined upper body configuration. Air flows upward along the inclined dust container and then rearward along the inclined upper body, effectively using the vertical and horizontal dimensions to accommodate components while maintaining a relatively smooth flow path that minimizes air resistance and preserves cleaning efficiency.

Implementation Method 1
a motor including a rotating shaft in the body, an eccentric load at the rotating shaft of the motor, which when rotated by a rotation of the rotating shaft, produces a vibration force
Implementation Method 2
a vibration plate located at the suction nozzle part to apply the vibration force to an object to be cleaned

AI summary
A vacuum cleaner to suction dust by applying vibration includes a motor, an eccentric load applied to a rotating shaft of the motor which when rotated by a rotation of the rotating shaft produces vibration force, a vibration plate to apply the vibration force to an object to be cleaned, and a vibration transfer member to transfer vibration force to the vibration plate.
