Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vacuum cleaner attachments lack the ability to safely and efficiently retrieve specific items from the waste chamber without compromising the cleanliness or integrity of the items, as existing methods are either hazardous, costly, or inefficient.
Innovation Solution
An in-line vacuum filter attachment with an actuatable filter paddle that can be toggled between positions to divert larger objects away from the airflow, allowing them to be collected independently of the main waste chamber, while maintaining unimpeded airflow for particulate matter.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If items are vacuumed directly into the main waste chamber, then the vacuum can collect all materials, but items desired for retrieval are mixed with waste and cannot be safely or efficiently retrieved
Solution Approach 1:
The waste collection system is divided into two separate chambers: a main waste chamber for disposable materials and a retrieval chamber for items desired for later use. This segmentation allows items to be collected without mixing with waste, enabling safe and efficient retrieval without contamination or damage from manual sifting through the main waste chamber.
2Ease of operation
If a stocking or temporary filter is placed in the vacuum hose to retrieve items, then item retrieval is possible, but the filter must be discarded after each use and may compromise airflow
Solution Approach 1:
The retrieval chamber is extracted as a separate component from the main waste chamber, allowing items to be collected independently without blocking the main airflow path. This eliminates the need for temporary filters that compromise vacuum efficacy while enabling continuous item retrieval capability.
Solution Approach 2:
Instead of discarding temporary filters after each use, the system recovers items in a dedicated retrieval chamber that can be easily emptied and reused. The chamber design allows for simple emptying without damaging the filtration system, enabling continuous operation without compromising vacuum performance.
3Ease of operation
If the waste chamber is sifted through to find desired items, then items can be retrieved, but the process is time-consuming and may spread waste and sharp objects
Solution Approach 1:
By segmenting the waste collection into two separate chambers from the moment of collection, items are never mixed with waste. This eliminates the need for time-consuming sifting operations and allows for immediate, safe retrieval of items from the dedicated retrieval chamber without exposure to waste or sharp objects.
4Adaptability or versatility
If an actuatable filter paddle is added to filter items from airflow, then items can be collected independently, but the device complexity increases
Solution Approach 1:
Rather than adding complex filtering mechanisms to the main airflow path, the system extracts a separate retrieval chamber that passively collects items. The actuatable paddle is simplified to merely gate access between chambers rather than perform complex filtration, reducing overall device complexity while maintaining versatility.

AI summary
An in-line vacuum filter comprises a manifold having an inlet, an outlet, a collecting container, and an actuatable filter paddle. A flow of air generated by a source of negative pressure travels from the inlet to the outlet. The actuatable filter paddle is positioned within the manifold such that it can be actuated between a first position and a second position. In the first position, the actuatable filter paddle is placed within the flow of air and in the second position, the actuatable filter paddle is removed from the flow of air. The filter paddle is preferably arcuate concave and comprises a plurality of apertures. In the first position, the filter paddle gradually diverts objects larger than a width of the apertures away from the flow of air. Diverted objects may travel to a removable collection container.
