Dual-Nozzle Pressure Washer Accessory for Wider Cleaning Coverage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
High-pressure washers with single nozzles have limited surface coverage, requiring multiple passes and increased time for cleaning, and cannot perform synergistic operations with different jet types simultaneously, leading to reduced efficiency and frequent nozzle changes.
Innovation Solution
An accessory for high-pressure washers with two dispensing nozzles that can operate simultaneously, allowing for different nozzle types (conical, fan-shaped, rotating) to be used in synergy, increasing surface coverage and reducing nozzle changes, along with a quick-release hydraulic connector for easy attachment and detachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of moving object
If a single dispensing nozzle is used, then the device complexity is low, but the surface coverage area is limited and productivity decreases
Solution Approach 1:
The accessory body is segmented into multiple outlet mouths (first outlet mouth and second outlet mouth), each connected to different types of dispensing nozzles. This segmentation allows simultaneous generation of multiple water jet types (conical, fan-shaped, rotating) from a single accessory, thereby increasing surface coverage area without proportionally increasing device complexity.
Solution Approach 2:
The accessory body serves multiple functions: it distributes pressurized water to different nozzle types, provides quick-release hydraulic connectors for easy nozzle changes, and enables synergistic operation of multiple jet types simultaneously. This multi-functionality increases surface coverage while keeping the added complexity manageable through integrated design.
2Adaptability or versatility
If multiple nozzle types are used sequentially, then different cleaning operations can be performed, but the loss of time increases due to frequent nozzle changes
Solution Approach 1:
Multiple outlet mouths and different nozzle types are merged into a single accessory body that can be attached to one dispensing gun. This allows simultaneous operation of conical, fan-shaped, and rotating nozzles, providing cleaning operation versatility without requiring time-consuming nozzle changes between different cleaning tasks.
Solution Approach 2:
The accessory is pre-configured with multiple outlet mouths connected to different nozzle types before operation begins. This preliminary preparation eliminates the need for frequent nozzle changes during cleaning operations, reducing time loss while maintaining versatility in performing different cleaning tasks simultaneously.
3Area of moving object
If the jet opening angle is increased to cover more surface area, then the surface coverage area increases, but the jet power at contact point decreases
Solution Approach 1:
Different outlet mouths are assigned different nozzle types with optimized opening angles for their specific functions: conical nozzles for focused high-power cleaning, fan-shaped nozzles for wider coverage, and rotating nozzles for spiral patterns. This local quality optimization allows each nozzle to operate at its optimal power-to-coverage ratio, increasing overall surface coverage without sacrificing jet power at contact points.
