Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vacuum cleaners with removable dust bins lack a secure and efficient mechanism for both installation and removal, often requiring complex operations and not ensuring proper locking during use.
Innovation Solution
A vacuum cleaner design featuring a dual-latch system with a spring-actuated mechanism that secures the dust bin during installation and allows for easy removal by transitioning between locked and unlocked positions, ensuring stable attachment and easy detachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a simple latch mechanism is used for dust bin attachment, then the device complexity is reduced, but the reliability of secure attachment during operation deteriorates
Solution Approach 1:
The latch mechanism is divided into two independent latches (first latch and second latch) that operate separately. Each latch provides a distinct locking function, with the first latch securing the dust bin during normal operation and the second latch enabling removal. This segmentation allows each latch to be simple in design while collectively providing high reliability through redundant locking paths.
2Reliability
If a secure locking mechanism is implemented to ensure stable attachment, then the reliability of dust bin attachment is improved, but the ease of operation for removal deteriorates
Solution Approach 1:
The latch system transitions from a static locked state to a dynamic unlocked state through the interaction between the two latches. During normal operation, both latches maintain a stable locked configuration. For removal, the system dynamically shifts as the first latch unlocks while the second latch remains engaged, guiding the dust bin along a removal path. This dynamic state transition enables easy operational switching between secure attachment and simple removal.
3Ease of operation
If a complex dual-latch system is used to ensure secure attachment and easy removal, then the ease of operation is improved, but the device complexity increases
Solution Approach 1:
The spring-loaded second latch automatically engages and disengages without user intervention. When the dust bin is installed, the spring automatically pushes the second latch into the locked position. During removal, the guide structure automatically interacts with the second latch to unlock it as the dust bin is pulled along the removal path. This self-service mechanism reduces the need for complex user-operated controls while maintaining ease of operation.
4Ease of operation
If the dust bin can be easily removed for maintenance, then the ease of operation is improved, but the reliability of secure attachment during use deteriorates
Solution Approach 1:
The attachment system is segmented into two independent latch paths: the first latch provides secure locking during normal vacuum operation, while the second latch provides the removal function. This segmentation ensures that the security function and removal function are independently implemented, allowing easy removal through the second latch without compromising the security provided by the first latch during operation.

AI summary
A vacuum cleaner includes a first latch moveable between a locked position and an unlocked position and a second latch moveable between a locked position and an unlocked position, and a spring pressing the second latch to the locked position. The vacuum cleaner also includes a dust bin securable on the housing with the first latch and the second latch. When the dust bin is being installed onto the housing, the second latch is moved from the locked position to the unlocked position until the spring presses the second latch back to the locked position. The dust bin is removable from the housing when the dust bin is installed on the housing, the first latch is in the unlocked position, and the second latch is in the locked position.
