Solution Overview
Problem
Existing surface cleaning apparatuses, such as carpet extractors, face challenges in achieving consistent and even fluid distribution during the cleaning process, leading to inefficiencies in cleaning performance and extended drying times.
Innovation Solution
A spray bar assembly with a body having internal reservoirs fluidly coupled by channels, providing a plurality of outlets along its length for consistent fluid distribution, integrated into a surface cleaning apparatus with a fluid delivery system that includes a fluid container, distributor, and recovery system, allowing for controlled fluid flow and efficient debris removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a conventional fluid delivery system is used, then the cleaning apparatus can deliver cleaning fluid to the surface, but the fluid distribution is inconsistent and uneven
Solution Approach 1:
The distributor body is segmented into multiple internal reservoirs that are fluidly coupled by channels. This segmentation allows the fluid to be distributed through multiple pathways, ensuring consistent and even fluid distribution across all outlets while maintaining a relatively simple overall structure.
Solution Approach 2:
Each outlet in the distributor is provided with a flow regulator that can independently adjust the fluid flow rate. This local quality adjustment ensures that each outlet delivers the appropriate amount of fluid based on specific cleaning requirements, achieving uniform overall distribution while allowing localized optimization.
2Productivity
If cleaning fluid is applied to the surface, then cleaning performance can be achieved, but drying time is extended
Solution Approach 1:
The flow regulators allow dynamic adjustment of fluid flow rates at each outlet, optimizing the amount of cleaning fluid applied to the surface. By controlling the fluid parameters (flow rate, distribution pattern), the system achieves effective cleaning while minimizing excess fluid that would extend drying time.
Solution Approach 2:
The system incorporates sensors that detect surface moisture levels and provide feedback to the control system. Based on this feedback, the flow regulators automatically adjust the fluid delivery rate, ensuring optimal cleaning performance while preventing over-saturation that would increase drying time.
3Area of stationary object
If multiple outlets are provided for fluid distribution, then coverage area is increased, but maintaining consistent flow at each outlet becomes difficult
Solution Approach 1:
The distributor body is divided into multiple internal reservoirs, each serving specific outlets. This segmentation creates independent fluid pathways that can be individually regulated, allowing consistent flow distribution across multiple outlets while maintaining manageable system complexity.
Solution Approach 2:
Each outlet is equipped with an independent flow regulator that can be adjusted to achieve consistent flow rates. This local control mechanism ensures that despite the multiple outlets covering a large area, each outlet delivers fluid with precise and consistent flow characteristics.

AI summary
A surface cleaning apparatus is provided with a fluid delivery system for delivering a cleaning fluid to the surface to be cleaned. The fluid delivery system includes one or more fluid supply tanks for storing a supply of cleaning fluid, a fluid distributor for applying the cleaning fluid to the surface to be cleaned, and a fluid supply conduit for delivering the cleaning fluid from the fluid supply tank to the fluid distributor.
