Cleaner with detachable controller
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cordless cleaners face challenges in suction efficiency and battery efficiency due to high flow path resistance, and the design of the controller and filter housing limits user convenience and aesthetic appeal.
Innovation Solution
The cleaner features a detachable controller with a manipulation unit and indication unit, located at the rear of the filter housing, which is configured to be easily accessible and interchangeable, and a filter housing that can be separated from the main body in a backward direction, reducing flow path resistance and improving suction efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the controller is integrated into the main body of the cleaner, then the structural complexity is reduced, but the ease of maintenance and aesthetic customization deteriorates
Solution Approach 1:
The controller is designed as a detachable module that can be separated from the main body of the cleaner. This segmentation allows the controller to be easily removed for maintenance or replacement without disassembling the entire device, while still maintaining a compact integrated appearance during normal use.
2Stability of the object's composition
If the filter housing is fixed to the main body, then the structural stability is improved, but the suction efficiency deteriorates due to high flow path resistance
Solution Approach 1:
The filter housing is designed with a dynamic attachment mechanism that allows it to be easily detached and reattached. This enables users to access and maintain the filter without permanent fixation, reducing flow path resistance by allowing optimal filter positioning while maintaining structural stability during operation.
3Ease of operation
If the controller is made larger to improve usability, then the ease of operation is improved, but the aesthetic appeal and compactness deteriorate
Solution Approach 1:
The controller utilizes the vertical space above the handle by extending upward rather than outward. This dimensional approach allows the controller to have sufficient size for comfortable operation while maintaining a sleek, compact profile that does not compromise the aesthetic appeal or increase the horizontal footprint of the cleaner.
4Ease of operation
If the controller is positioned to be easily accessible, then the ease of operation is improved, but it may interfere with the detachment of the filter housing
Solution Approach 1:
The controller is positioned within the spatial envelope of the filter housing, nesting it in a way that allows both components to coexist without interference. The controller is located above the handle in a position that is easily accessible to users but does not block the detachment path of the filter housing from the main body.
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 suction efficiency, increases battery life, and allows for easier maintenance and aesthetic customization, improving user convenience and cleaning performance.
Implementation Method 1
A cleaner, for example, a vacuum cleaner, sucks in air containing foreign substances such as dust by using negative pressure
Implementation Method 2
a dust collector in the main body and configured to separate foreign substances from the air that was sucked in
Implementation Method 3
a filter in the filter housing and configured to filter the air from which foreign substances have been separated by the dust collector
