Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pressure washer nozzle designs are not user-friendly for cleaning confined spaces, such as car engines, as they do not effectively accommodate angled access and pressure distribution.
Innovation Solution
A low pressure washer nozzle tip with an angled design, multiple openings, and a retaining nut, allowing for secure attachment to a pressure washer gun, made of durable materials, facilitating efficient fluid exit at 40-60 psi and maneuverability in tight spaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a traditional straight nozzle design is used, then the structure is simple and easy to manufacture, but it cannot effectively clean confined spaces such as car engines
Solution Approach 1:
The nozzle tip is angled at approximately 100 to 105 degrees relative to the main shaft axis, creating an asymmetric design that enables the nozzle to effectively clean confined spaces and complex geometries such as car engines while maintaining a relatively simple structural composition
2Productivity
If high pressure is used for cleaning, then cleaning effectiveness is improved, but the risk of damage to delicate components increases
Solution Approach 1:
The nozzle tip includes multiple openings (at least two, preferably three or more) distributed across its surface, which segments the water flow into multiple streams. This segmentation allows the nozzle to deliver effective cleaning power while distributing the force to reduce the risk of damage to delicate components
Solution Approach 2:
The openings are positioned at specific locations and angles on the nozzle tip surface, creating localized flow patterns that optimize cleaning effectiveness for confined spaces while controlling pressure distribution to prevent damage
3Strength
If the nozzle is made of heavy-duty material for durability, then strength is improved, but the weight increases reducing maneuverability
Solution Approach 1:
The nozzle is constructed from composite materials, specifically a polyamide polymer matrix reinforced with long glass fibers (at least 3mm length). This composite structure provides exceptional strength, durability, and heat resistance while maintaining a lightweight construction that enhances maneuverability
4Ease of operation
If the nozzle tip is angled for better access to confined spaces, then ease of operation is improved, but manufacturing precision requirements increase
Solution Approach 1:
The nozzle tip is angled at approximately 100 to 105 degrees relative to the main shaft axis, creating an asymmetric design that enables the nozzle to effectively clean confined spaces and complex geometries such as car engines while maintaining a relatively simple structural composition
Solution Approach 2:
The angle parameter is optimized within a specific range (100-105 degrees) rather than requiring a single precise value, which provides manufacturing tolerance and reduces precision requirements while still achieving the desired operational effectiveness

AI summary
A low pressure washer nozzle tip is provided. The low pressure washer nozzle tip has an angled tip with multiple openings and a corresponding retaining nut. The nozzle tip is secured to the retaining nut and wherein both are removably secured to a shaft of a pressure washer gun. The tip of the nozzle is angled at approximately a one hundred to a one-hundred and five-degree axis with respect to a main shaft of the pressure washer.
