Rotatable Sudsing Sprayer Attachment With Teeth-Tab Lock
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Consumer sudsing sprayers are often bulky and difficult to manipulate, and the attachment and detachment of sudsing attachments from the sprayer handle are cumbersome, making them inconvenient for washing cars.
Innovation Solution
A sudsing sprayer with a detachable canister and a teeth and tab attachment structure that allows the sudsing attachment to rotatably lock onto a spraying handle, enabling easy detachment and attachment, and a second nozzle configured to eject a flat stream of water that mixes with detergent to create suds.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If consumer sudsing sprayers are designed to be compact and easy to manipulate, then ease of operation is improved, but the attachment and detachment mechanism becomes more complex
Solution Approach 1:
The sprayer is divided into separate modular components: a handle, a detachable sudsing attachment, and a removable canister. This segmentation allows each component to be optimized independently for ease of handling while the modular connection points use simple teeth-and-tab mechanisms that reduce overall system complexity.
Solution Approach 2:
The attachment mechanism incorporates rotational movement capability, allowing the sudsing attachment to be easily attached and detached by simple rotational motions. This dynamic attachment method improves ease of operation compared to fixed or multi-step connection mechanisms.
2Ease of operation
If the sudsing attachment is made detachable for easy removal, then ease of operation is improved, but the connection reliability may deteriorate
Solution Approach 1:
The attachment interface incorporates curved or rounded engagement surfaces that allow for smooth rotational attachment and detachment. The curved geometry provides natural guidance for alignment while maintaining secure engagement during use, balancing ease of detachment with connection reliability.
Solution Approach 2:
The teeth-and-tab attachment structure is designed to self-align and self-lock during rotational attachment, eliminating the need for complex alignment procedures or additional fastening steps. This self-service mechanism ensures reliable connection while maintaining simplicity and ease of operation.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution provides a user-friendly, easily detachable sudsing attachment that simplifies the car washing process by allowing for efficient mixing of detergent and water, creating a sudsing spray with adjustable nozzle direction, enhancing the convenience and effectiveness of car washing.
Implementation Method 1
the second channel narrows such that the resulting pressure in the second channel induces the detergent and water to mix and sud
Implementation Method 2
the second nozzle is configured to eject the flow of water in a substantially flat stream
