Detachable Controller Vacuum Cleaner Backward Filter Housing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vacuum cleaners face challenges in maintaining efficient suction performance and user convenience due to high flow path resistance and cumbersome controller designs, particularly in cordless models, which affect battery efficiency and ease of maintenance.
Innovation Solution
A detachable controller design for vacuum cleaners that allows for backward separation of the filter housing, reduces flow path resistance, and enables interchangeable controllers with various designs to enhance user convenience and maintainability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of repair
If the controller is integrated into the main body, then the structure is compact and simple, but the filter housing cannot be detached backward and maintenance is difficult
Solution Approach 1:
The controller is separated from the main body and placed on the filter housing, allowing the filter housing to be detached independently for maintenance. This segmentation enables the filter housing to be removed backward without the controller interfering, while keeping the overall structure relatively simple.
2Ease of repair
If the controller is placed on the filter housing, then the filter housing can be detached backward, but the controller interferes with the detachment movement
Solution Approach 1:
The controller is positioned on the filter housing in such a way that it can be detached along with the filter housing. The controller's attachment mechanism is designed to move in the same backward direction as the filter housing detachment, eliminating interference with the detachment movement.
3Force
If the flow path resistance is high, then the suction force is strong, but the battery consumption increases and cleaning time decreases
Solution Approach 1:
The dust collector is designed to efficiently separate foreign substances from the air flow, reducing the resistance to air flow. By effectively removing dust particles, the system maintains strong suction force while minimizing the energy required to move air through the system, thus reducing battery consumption.

AI summary
A cleaner includes a main body and a controller configured to control an operation of the cleaner. The main body may be provided with a suction fan to generate a suction force for sucking in air, a dust collector to separate foreign substances from the sucked-in air, and a filter housing supporting a filter to filter foreign substances out of the air that has passed through the dust collector and the suction fan. The controller is located at the rear of the filter housing. The controller is detachable from the main body.
