Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing surface cleaning apparatuses lack a convenient and ergonomic design for detaching and emptying the dirt collection chamber, making it difficult for users to access and dispose of collected dirt efficiently.
Innovation Solution
A surface cleaning apparatus with a pivotally connected dirt separation device that includes an actuator member and coupling device, allowing the user to detach and handle the dirt separation device with one hand, facilitating easy emptying and reattachment, and featuring a cyclonic separator for efficient dirt collection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the dirt separation device is made detachable for easy emptying, then the ease of operation is improved, but the device complexity increases due to additional coupling mechanisms
Solution Approach 1:
The dirt separation device is segmented from the main housing, allowing it to be detached and removed independently. This segmentation enables the user to easily empty the dirt collection chamber by separating it from the main body, directly improving ease of operation while the coupling mechanism manages the complexity aspect.
Solution Approach 2:
A coupling device acts as an intermediary mechanism between the dirt separation device and the housing. This coupling device includes coupling members that engage with each other to securely attach or detach the dirt separation device, providing a controlled interface that balances ease of operation with manageable device complexity.
2Ease of operation
If the dirt separation device is positioned forwardly of the suction source, then the ease of operation is improved for access, but the center of gravity shifts affecting handling stability
Solution Approach 1:
The dirt separation device is positioned forwardly of the suction source, creating a dynamic balance that allows easy access for the user's hand while the overall device maintains stability through the distributed weight arrangement and ergonomic handle design. This dynamic positioning optimizes both accessibility and handling characteristics.
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 convenient and ergonomic access to the dirt collection chamber for emptying, improving user experience and efficiency in dirt disposal while maintaining effective dirt separation and collection capabilities.
Implementation Method 1
a separator in the form of a cyclonic separator which causes dirt-laden air to flow in a swirling motion around the body of the separator to cause the dirt to separate from the dirt-laden air
Implementation Method 2
causes dirt-laden air to flow in a swirling motion around the body of the separator to cause the dirt to separate from the dirt-laden air
