Recovery Tank Strainer for Hair and Debris Separation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing surface cleaning apparatuses face challenges in efficiently separating large debris and hair from cleaning fluids before emptying the recovery tank, leading to potential clogging of drains and pipes, and require manual and unsanitary removal of debris.
Innovation Solution
A surface cleaning apparatus with a recovery tank assembly that includes a strainer configured to strain large debris and hair out of the tank prior to emptying, allowing for easy separation and disposal of debris while draining smaller debris and fluid back into the tank.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the recovery tank is emptied directly without separation, then the emptying process is simple and quick, but large debris and hair clog drains and pipes
Solution Approach 1:
A strainer assembly is introduced as an intermediary component between the recovery tank and the drain. The strainer contains a collection chamber that captures large debris and hair, preventing them from entering the drain while allowing cleaning fluid to pass through. This mediator resolves the contradiction by enabling direct emptying without drain clogging.
Solution Approach 2:
The strainer assembly segments the emptying process into two pathways: one for large debris (collected in the collection chamber) and one for cleaning fluid (drained through the drain). This segmentation allows simultaneous disposal of different materials through appropriate channels, maintaining productivity while preventing clogs.
2Ease of operation
If manual removal of debris is performed, then large debris can be removed, but the process is unsanitary and time-consuming
Solution Approach 1:
The strainer assembly serves as a built-in separation system that automatically filters large debris from the cleaning fluid. Users simply remove and discard the strainer with captured debris, eliminating the need for manual picking through unsanitary material. This reduces both the time required and the sanitary concerns of debris removal.
Solution Approach 2:
The strainer assembly performs the debris collection function automatically during the normal emptying process. The collection chamber passively captures large debris as fluid drains through it, requiring no additional manual intervention or time investment from the user beyond normal emptying procedures.
3Reliability
If a strainer assembly is added to separate debris, then drain clogging is prevented, but the device complexity increases
Solution Approach 1:
The strainer assembly is merged with the existing recovery tank structure, combining the separation function with the tank's natural emptying process. The collection chamber integrates with the tank interior, and the strainer uses the existing drain opening, avoiding the need for separate complex systems while maintaining reliable clog prevention.
4Manufacturing precision
If the strainer collects all debris, then separation is effective, but the collection chamber fills quickly and requires frequent emptying
Solution Approach 1:
The strainer assembly is designed with specific local qualities: the collection chamber is positioned and sized to optimize debris capture, and the strainer mesh is configured with appropriate opening sizes to separate debris effectively while allowing fluid passage. This targeted design achieves effective separation without unnecessarily filling the collection chamber, reducing emptying frequency.

AI summary
A surface cleaning apparatus includes include at least a recovery system for removing the spent cleaning fluid and debris from the surface to be cleaned and storing the spent cleaning fluid and debris. The recovery system is provided with a recovery tank having a removably strainer that is configured to strain large debris and hair out of the recovery tank prior to emptying the recovery tank.
