Removable Dust Bag Container for Leak-Safe Stick Vacuum Emptying
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing stick vacuum cleaners pose a risk to users when emptying the dust container, as dust can leak or the bag may be accidentally dropped or damaged during removal and disposal.
Innovation Solution
A stick vacuum cleaner design featuring a removable dust container with a snap-in mechanism, a spring-loaded blocking device, and a visual indicator, allowing for easy removal and reattachment of the dust bag, which prevents accidental closure when empty and facilitates safe disposal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the dust bag is made removable for easy disposal, then the ease of operation is improved, but the reliability deteriorates due to risk of dust leakage or accidental damage during removal
Solution Approach 1:
The dust container is segmented into a removable dust bag and a fixed container body, allowing the dust bag to be easily removed for disposal while the container remains securely attached to the vacuum cleaner. This segmentation enables easy operation without compromising the overall system reliability.
Solution Approach 2:
A blocking device acts as an intermediary mechanism between the aperture and the dust bag. When the dust bag is properly installed, the blocking device prevents the aperture from closing, ensuring that dust cannot leak while still allowing easy removal of the dust bag when needed.
2Reliability
If the aperture is designed to close automatically for safety, then the reliability is improved by preventing dust exposure, but the ease of operation deteriorates due to difficulty in dust bag removal
Solution Approach 1:
The blocking device is pre-configured to automatically prevent aperture closure when a dust bag is properly installed. This preliminary action ensures that the aperture remains open for dust bag access while maintaining safety, eliminating the need for manual intervention to balance safety and operability.
Solution Approach 2:
The system uses the presence of the dust bag itself to control the blocking device. When the dust bag is installed, it automatically triggers the blocking mechanism to prevent aperture closure, and when removed, the aperture can close safely without requiring additional user actions.
3Productivity
If the container is made detachable for easy emptying, then the productivity is improved by simplifying the emptying process, but the device complexity increases due to additional attachment mechanisms
Solution Approach 1:
The dust container is designed as a detachable unit from the main vacuum cleaner body, allowing quick removal for emptying. This segmentation improves productivity by simplifying the emptying process while the standardized attachment mechanism keeps the added complexity minimal and manageable.
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
Enables users to safely and efficiently empty and replace the dust bag without risk of leakage or damage, improving the overall emptying process and user safety.
Implementation Method 1
the dust bag is configured to press against the spring-loaded member when placed in the bracket, causing a spring of the spring-loaded member to compress and move the spring-loaded member in a transversal direction towards an interior of the container
Implementation Method 2
removal of the dust bag causes the spring to expand and move the spring-loaded member in a transversal direction towards an exterior of the container, thereby blocking the aperture from being closed
