Vacuum Cleaner Handle Release Mechanism for One-Hand Dust Disposal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face difficulty in operating the release button to separate the main body from the housing in vacuum cleaners, as the button is typically positioned inside the housing, making it hard to press with one hand while gripping the handle with the other.
Innovation Solution
A release button is integrated into the handle, connected to the fixing device by a wire, allowing the user to operate the fixing device to couple or decouple the main body from the housing with ease, reducing the distance between the button and the housing end.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the release button is positioned inside the housing, then the fixing device can be operated, but the user has difficulty pressing the button with one hand while gripping the handle with the other
Solution Approach 1:
A wire is introduced as an intermediary element to transmit the pressing force from the release button (now positioned on the handle) to the fixing device inside the housing. This allows the button to be relocated to a more accessible position while still operating the fixing mechanism, resolving the contradiction between ease of operation and structural constraints.
2Ease of operation
If the release button is moved to the handle, then the user can easily press the button with one hand, but the distance between the button and the housing end increases
Solution Approach 1:
The wire serves as a flexible intermediary that bridges the increased distance between the relocated button on the handle and the fixing device in the housing. This allows the button to be positioned for optimal user accessibility while maintaining functional connection to the fixing mechanism through the wire transmission medium.
3Ease of operation
If the button is positioned in the housing, then the structure is compact, but the user cannot easily operate it while holding the handle
Solution Approach 1:
The wire acts as a flexible connection that enables the button to be installed in a user-friendly position on the handle while still effectively operating the fixing device in the housing. This resolves the manufacturing consideration by providing a simple wire connection method that accommodates the relocated button position.

AI summary
A cleaning device comprises: a housing having a dust collection chamber; a main body, moveable with respect to the housing, to be coupled to the housing and to be decoupled from the housing, the main body includes a handle; a fixing device, arrangeable in the main body, to couple the main body to the housing to the housing while the main body is moved to a first position with respect to the housing and to decouple the main body from the housing while the main body is moved to a second position with respect to the housing; and a releasing button arrangeable with respect to the main body, and connectable to the fixing device by a wire so that while the release button is connected to the fixing device, the release button is useable to operate the fixing device.
