Dual-Nozzle Mop Sprayer With Rotating Collar Pattern Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional spray mops lack a convenient and reliable mechanism for adjusting the pattern of liquid spray, often resulting in mixed quality, reliability, and ease of use issues.
Innovation Solution
A sprayer assembly with a reservoir, pump, and dual supply tubes connected to nozzles, featuring a rotatable collar with protrusions that selectively pinch one supply tube closed, allowing for easy adjustment between different spray patterns by switching between two or more nozzles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single nozzle with pattern adjustment is used, then the device complexity is reduced, but the spray pattern quality and reliability deteriorate
Solution Approach 1:
The spray system is divided into multiple independent nozzles (first nozzle and second nozzle), each capable of producing different spray patterns. Instead of attempting to adjust a single nozzle to achieve multiple patterns, the system segments the spray function across multiple nozzles, allowing each nozzle to be optimized for its specific pattern while providing reliable, consistent performance.
Solution Approach 2:
The spray device achieves multi-functionality by incorporating multiple nozzles that can be selectively activated. The system can produce different spray patterns (narrow, focused vs. wide, dispersed) by selecting which nozzle to use, making the device universally applicable to various cleaning applications without compromising reliability.
2Adaptability or versatility
If a pattern adjustment mechanism is added to conventional spray devices, then spray pattern versatility is improved, but ease of operation and reliability worsen
Solution Approach 1:
The system provides dynamic adaptability through a rotatable collar that can be easily rotated to select between different spray patterns. This dynamic adjustment mechanism allows the user to switch between nozzles and patterns quickly and effortlessly, maintaining ease of operation while achieving spray pattern versatility.
3Manufacturing precision
If a complex pattern adjustment mechanism is implemented, then spray pattern quality is improved, but ease of manufacture deteriorates
Solution Approach 1:
By segmenting the spray function into multiple simple nozzles rather than creating one complex adjustable nozzle, the manufacturing process is simplified. Each nozzle can be manufactured independently using standard nozzle manufacturing processes, ensuring consistent quality without requiring complex assembly or calibration procedures.
