Solution Overview
Problem
Existing portable extraction cleaners face challenges in efficiently managing the hose attachment and fluid coupling, leading to potential kinking and tension issues with the flexible hose, which can affect the cleaning performance and user convenience.
Innovation Solution
A hose attachment assembly with a suction conduit and fluid coupling that is removably coupled to the base, allowing the flexible hose to be nested and minimizing tension, includes a tubular member with elbow-shaped sections for secure fluid communication between the recovery tank and the suction source, and a quick disconnect fluid coupling for easy detachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the hose is permanently attached to the base, then fluid communication is maintained, but the hose experiences kinking and tension issues affecting cleaning performance
Solution Approach 1:
The hose attachment assembly is divided into separable components: the hose, the suction conduit, and the fluid coupling. This segmentation allows the hose to be detached from the base when not in use, eliminating tension and kinking issues while maintaining fluid communication during operation through the reusable fluid coupling connection.
2Ease of operation
If the hose attachment assembly is made removable, then hose tension and kinking are reduced, but fluid communication may be compromised
Solution Approach 1:
The fluid coupling acts as an intermediary component that maintains fluid communication between the hose and the base when the hose attachment assembly is removed. This intermediary connection ensures that fluid transfer continues uninterrupted during cleaning operations while allowing the hose to be freely positioned and stored.
3Stability of the object's composition
If the suction conduit is permanently fixed to the base, then structural stability is maintained, but the hose attachment assembly cannot be easily removed for storage
Solution Approach 1:
The suction conduit is designed as a separate, removable component that can be detached from the base. This segmentation provides structural stability during use through secure attachment mechanisms while enabling easy removal and storage of the entire hose attachment assembly when not in use.

AI summary
An extraction cleaner includes a supply tank, a recovery tank, a pump, a suction source, a base configured to support the suction source and the pump, an external hose, and a hose attachment assembly. The hose attachment assembly has a suction conduit extending from a suction inlet connected to the proximal end of the hose to a suction outlet in fluid communication with the recovery tank. The suction conduit is removable from the base with the hose. The hose attachment assembly also has a fluid coupling which is removable with the suction conduit. The fluid coupling extends from a coupling inlet in fluid communication with the pump to a coupling outlet coupled to a supply tube having one or more portions carried within the suction conduit. The proximal end of the hose is at least partially nested adjacent the base when the suction conduit is coupled to the base.
