Solution Overview

Problem

Existing pressurized spray cleaning apparatuses for brick structures face issues with spray diffusion pattern, fluid flow, misalignment, fatigue, and breaking, particularly in the design of the spray head and distributor body, and lack efficient mixing of chemicals from separate supply sources.

Innovation Solution

A spray head with a corrosion-resistant distributor body of trapezoidal configuration, featuring a concave top surface and angled discharge apertures, combined with a spray nozzle support body that mixes chemical cleaning fluid with heated carrier fluid before deflection, and a stainless steel elbow guard for enhanced protection, ensuring improved diffusion and secure mounting.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If a pressurized spray cleaning apparatus is used, then cleaning efficiency is improved compared to manual cleaning, but spray diffusion pattern and fluid flow problems occur

Engineering Contradiction:
Improvecleaning efficiencyVSAvoidspray diffusion pattern
Core Design Contradiction:
ProductivityVSManufacturing precision

Solution Approach 1:

The distributor body features a concave top surface with specifically positioned discharge apertures and angled bores that create localized fluid dynamics zones. This local quality variation optimizes spray diffusion pattern by controlling fluid flow characteristics at specific locations within the distributor body, resolving the spray diffusion problems while maintaining high cleaning efficiency.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The distributor body incorporates a concave (curved) top surface instead of a flat surface. This curvature modifies the fluid flow path and spray diffusion pattern, improving the distribution of cleaning fluid while maintaining effective pressurized spray cleaning performance.

Inventive Principle:
Principle #14Spheroidality (Curvature)

2Ease of manufacture

If the spray head is constructed with standard materials, then production cost is reduced, but fatigue and breaking problems occur

Engineering Contradiction:
Improveproduction costVSAvoidfatigue resistance
Core Design Contradiction:
Ease of manufactureVSReliability

Solution Approach 1:

The spray head combines a corrosion-resistant distributor body material with a separate support body structure. This composite construction uses materials optimized for their specific functions - the distributor body resists chemical corrosion from cleaning fluids while the support body provides structural strength, thereby improving fatigue resistance and breaking resistance without excessive cost increase.

Inventive Principle:
Principle #40Composite materials

Solution Approach 2:

The design incorporates a support body that structurally reinforces the distributor body before fatigue or breaking can occur during operation. This preventive structural design cushions against the high stresses of pressurized fluid flow, reducing the likelihood of fatigue failure and breaking while maintaining manufacturing feasibility.

Inventive Principle:
Principle #11Beforehand cushioning (Prior cushioning)

3Duration of action of stationary object

If the distributor body is made corrosion resistant, then durability is improved, but manufacturing complexity increases

Engineering Contradiction:
ImprovedurabilityVSAvoidmanufacturing complexity
Core Design Contradiction:
Duration of action of stationary objectVSDevice complexity

Solution Approach 1:

The spray head is divided into separate components - the distributor body and the support body - allowing the distributor body to be manufactured from corrosion-resistant material independently. This segmentation enables the use of specialized materials where needed without requiring the entire assembly to be made from complex, high-cost materials, thereby balancing durability with manufacturing complexity.

Inventive Principle:
Principle #1Segmentation

4Adaptability or versatility

If separate fluid supply sources are used, then cleaning versatility is improved, but mixing efficiency is insufficient

Engineering Contradiction:
Improvecleaning versatilityVSAvoidmixing efficiency
Core Design Contradiction:
Adaptability or versatilityVSManufacturing precision

Solution Approach 1:

The distributor body integrates multiple fluid supply sources into a single mixing chamber where cleaning fluid and carrier fluid converge. The angled bores and discharge aperture geometry are designed to promote intimate mixing of the fluids as they combine, achieving efficient mixing while maintaining the versatility of using separate fluid supplies for different cleaning requirements.

Inventive Principle:
Principle #5Merging (Combining)

AI summary

A spray head with improved distributor body for a high pressure spray cleaning apparatus is provided. The spray head is carried on the end of a hand held wand with control valves to separately regulate flow through a pair of fluid circuits, the spray head having a nozzle that sprays heated water in a fan-like pattern against a deflecting edge of a distributor body. Cleaning chemicals are forced through an aperture into the fan-like pattern prior to its striking the deflecting edge to be intimately mixed with the heated water to produce a mixture that strikes the deflecting edge and is deflected therefrom in a highly concentrated form at a high velocity. An elbow guard provides improved protection for the chemical cleaning fluid flow line where it connects to the spray head. Also disclosed is a spray head that allows for the separate application of fluids delivered from separate supply sources.
