Hand-guided cyclone vacuum cleaner
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hand-guided cyclone vacuum cleaners complicate the removal and operation of the suction container, making it difficult for users to manage effectively.
Innovation Solution
A hand-guided cyclone vacuum cleaner design featuring a rotatable operating element that transitions between inseparable and separable connections, allowing for easy handling and operation of the suction container using a single intuitive rotary element, integrated into the vacuum cleaner's design with a positive-locking mechanism and latching cams for secure attachment and detachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a complex removal mechanism is used for the suction container, then the connection security is improved, but the ease of operation deteriorates
Solution Approach 1:
The operating element transitions between two rotational positions (first position for secure connection, second position for separation), dynamically changing the connection state between inseparable and separable to resolve the contradiction between connection security and ease of removal
Solution Approach 2:
The operating element acts as an intermediary mechanism that mediates between the user's removal action and the connection state, providing a clear visual indicator (position-dependent visibility) to guide the user through the removal process while ensuring proper engagement
2Adaptability or versatility
If multiple operating elements are used for different functions, then the functional versatility is improved, but the device complexity increases
Solution Approach 1:
A single operating element performs multiple functions: it controls both the connection state (inseparable/separable) and the emptying state (closed/open) of the suction container, eliminating the need for separate operating elements and reducing overall device complexity
Solution Approach 2:
The patent merges the connection control function and the emptying control function into one integrated operating element, combining what would traditionally require separate mechanisms into a single unified component that the user operates in sequence

AI summary
A hand-guide cyclone vacuum cleaner includes: a device body which has a drive unit for generating a suction air flow; a suction container, which is connected to the device body, for receiving suction material; and an operating element arranged at one end of the suction container opposite an end of the suction container on which the device body is arranged. The operating element is rotatable from a first position into a second position and from the second position into the first position. The device body is inseparably connected to the suction container in the first position. The device body is separably connected to the suction container in the second position.
