Removable Spray Tip Mounting for Secure Carpet Extractor Cleaning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional carpet extractors lack a secure and efficient mechanism for mounting and connecting the spray tips to the spray tip receivers, leading to potential detachment during use, which can disrupt the cleaning process.
Innovation Solution
The surface cleaning apparatus incorporates a removable connection system with resilient tabs on the spray tips and notches in the spray tip receivers, ensuring a secure and reliable mounting mechanism that prevents detachment during operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a removable connection mechanism is used between spray tip and spray tip receiver, then the spray tip can be easily removed and replaced, but the connection may become detached during use
Solution Approach 1:
The connection mechanism is segmented into resilient tabs on the spray tip and corresponding notches on the spray tip receiver, allowing independent movement and engagement of each tab-notch pair. This segmentation enables easy removal while maintaining secure connection during use.
Solution Approach 2:
The resilient tabs are designed to be flexible and dynamic, allowing them to deflect during insertion and removal operations. During normal use, the tabs maintain constant contact pressure against the notches, providing secure retention while still allowing for easy removal when needed.
2Reliability
If a secure connection mechanism with resilient tabs is used, then the spray tip remains firmly mounted, but the complexity of the connection system increases
Solution Approach 1:
The resilient tabs are localized features on the spray tip, concentrating the complex retention function into small, discrete elements rather than requiring a complex overall connection system. Each tab is a simple resilient element that provides secure mounting through its deflection and contact with the notches.
Solution Approach 2:
The resilient tabs automatically engage with the notches when the spray tip is inserted, and automatically maintain retention pressure during use. The tabs self-adjust to ensure proper engagement without requiring additional adjustment mechanisms or complex control systems.

Function Achieved in This Case
This solution enhances the stability and reliability of the spray tip connection, ensuring consistent fluid distribution and improved cleaning performance by maintaining the spray tips in place throughout the cleaning process.
Implementation Method 1
The removable connection includes at least one resilient tab on the spray tip and at least one notch in the spray tip receiver that abuts the at least one resilient tab

AI summary
A surface cleaning apparatus has a supply tank for holding a supply of cleaning solution, a spray tip in fluid communication with the supply tank for distributing the cleaning solution to the surface to be cleaned, and a spray tip receiver. A removable connection between the spray tip and spray tip receiver removably mounts the spray tip to the spray tip receiver.
