Vacuum Debris Ejector with Telescoping Push Rod for Forced Disposal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing surface cleaning apparatuses, such as vacuum cleaners, face challenges in efficiently disposing of debris accumulated in the collection assembly, often requiring manual removal or shaking due to debris becoming stuck, especially when relying solely on gravity for disposal.
Innovation Solution
A surface cleaning apparatus with a debris ejector mechanism that includes a push rod operably coupled to a debris ejector, allowing for the forceful ejection of debris through a bottom outlet, combined with a telescoping design to conserve space and facilitate easy mounting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If debris disposal relies solely on gravity, then the device structure remains simple, but debris becomes stuck and disposal efficiency deteriorates
Solution Approach 1:
The debris ejector is designed to be manually operated by the user through a simple pushing motion, allowing the system to self-eject debris without requiring external power sources or complex automated mechanisms. The user activates the ejector by pushing it downward, which automatically triggers the debris ejection process through the opening in the pre-motor filter assembly.
Solution Approach 2:
The debris ejector mechanism extracts the essential function of debris removal from complex automated systems and implements it through a simple mechanical pushing action. The ejector separates the debris ejection function from the main vacuum operation, allowing independent activation when needed.
2Productivity
If a debris ejector mechanism is added to forceful ejection, then debris disposal efficiency improves, but device complexity increases
Solution Approach 1:
The debris ejector mechanism is merged with the existing pre-motor filter assembly structure. The ejector integrates with the filter housing and utilizes the existing opening in the pre-motor filter assembly as the ejection path, combining multiple functions (filtration and debris ejection) into a single integrated structure rather than adding separate components.
Solution Approach 2:
The pre-motor filter assembly serves dual functions: it acts as a filter for the airflow path and simultaneously serves as the ejection chamber for the debris ejector mechanism. The opening in the pre-motor filter assembly is used both for air passage and for debris ejection, maximizing the utility of existing structural elements.
3Volume of moving object
If the push rod is made telescoping to conserve space, then space utilization improves, but manufacturing precision requirements increase
Solution Approach 1:
The push rod employs a telescoping design where one segment of the rod is nested within another segment, similar to a nested doll structure. This allows the push rod to extend to full length when needed for debris ejection and retract to a compact size for storage, maximizing space utilization within the filter assembly housing.

AI summary
A surface cleaning apparatus includes a separating and collection assembly defining a collection chamber which receives debris and has a debris outlet, a cover assembly having a pre-motor filter, a debris ejector, and a push rod operably coupleable to the debris ejector to displace the debris ejector relative to the debris outlet. The push rod can be accommodated by an opening of the pre-motor filter.
