Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Bagless vacuum cleaners face challenges with dust separation efficiency due to limited space in dust collecting units, requiring frequent emptying and additional components for dust compression, which complicates the process and increases costs and sensitivity to part failure.
Innovation Solution
A vacuum cleaner design featuring a dust separating device with a releasable second part that can be moved within the dust collecting container for compression, utilizing a cover plate with sealing members to minimize dust disturbance and facilitate easy emptying, and an actuator for one-handed operation during cleaning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If a dust collecting unit with limited space is used in a bagless vacuum cleaner, then the vacuum cleaner structure is compact, but the dust collecting unit fills up quickly requiring frequent emptying
Solution Approach 1:
The patent applies preliminary action by automatically compressing dust in the collecting unit during vacuum operation, before emptying is needed. The compression arrangement reduces dust volume proactively, extending the interval between emptying operations and preventing the unit from filling up quickly.
2Productivity
If a rotating dust compressing arrangement with driving unit is added to the dust storage chamber, then dust compression is achieved, but the system becomes more complex and sensitive to part failure
Solution Approach 1:
The patent merges the compression function with the existing vacuum cleaner structure. The compression arrangement is integrated into the dust storage chamber and can be actuated by the existing driving unit or manually, combining multiple functions into existing components rather than adding entirely separate systems.
Solution Approach 2:
The compression arrangement is designed to be manually operable by the user without requiring additional automated driving units. The user can directly operate the compression mechanism, eliminating the need for complex automated systems while maintaining dust compression capability.
3Ease of operation
If the dust storage chamber is designed to be emptied by removing top cover and first cyclone, then dust can be removed, but the emptying process involves multiple steps reducing ease of operation
Solution Approach 1:
The patent segments the dust collecting unit into detachable parts, specifically making the dust storage chamber separable from the main body. This allows the chamber to be easily removed and emptied without requiring disassembly of the top cover or cyclone components, simplifying the emptying process to a single removal action.
4Productivity
If gravity is used to drop dust in the dust collecting unit, then dust separation is achieved, but the dust becomes loosely compacted reducing storage capacity
Solution Approach 1:
The patent applies preliminary action by compressing the dust that has been separated by gravity before the user needs to empty the unit. This compression reduces the volume of loosely compacted dust, increasing the effective storage capacity of the collecting unit without affecting the gravity-based separation process.
