Innovation Solution

A dry to wet abrasive blast machine conversion kit that utilizes existing penetrations in the blast pot to install a multi-function fluid manifold for storing and conveying liquid, allowing for wet abrasive blasting operations without compromising safety ratings or structural integrity, featuring a control panel for remote rinse and blasting operations.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If dry abrasive blasting equipment is converted to wet abrasive blasting by adding new penetrations to the blast pot, then wet blasting functionality is achieved, but safety ratings and structural integrity are compromised

Engineering Contradiction:
Improvewet blasting functionalityVSAvoidsafety ratings
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The existing penetrations in the blast pot are designed to serve multiple functions - originally intended for dry blasting operations, they are now configured to also accommodate wet blasting components. The fluid manifold system utilizes these existing openings to introduce water and slurry without requiring additional penetrations, thereby maintaining the blast pot's structural integrity and safety ratings while achieving wet blasting capability

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The conversion kit leverages the existing structural features of the blast pot (the original penetrations) to provide wet blasting functionality. Rather than requiring external modifications that would compromise the vessel, the system uses the blast pot's own existing openings to deliver water and slurry, making the conversion self-contained and non-invasive to the original structure

Inventive Principle:
Principle #25Self-service

2Productivity

If dry abrasive blasting is performed, then surface cleaning is achieved, but dust clouds are produced creating health hazards

Engineering Contradiction:
Improvesurface cleaningVSAvoiddust clouds
Core Design Contradiction:
ProductivityVSObject-generated harmful factors

Solution Approach 1:

Water acts as an intermediary substance introduced through the fluid manifold system. This water mediates between the abrasive blasting operation and the environment by capturing dust particles that would otherwise become airborne. The water absorbs and binds the dust, preventing it from forming harmful dust clouds while allowing the surface cleaning function to proceed effectively

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The introduction of water changes the physical parameters of the blasting environment - specifically, it transforms the airborne dust particles into a wet slurry mixture. This parameter change (from dry to wet conditions) fundamentally alters the behavior of particulates, preventing them from becoming airborne and creating health hazards while maintaining the surface cleaning capability

Inventive Principle:
Principle #35Parameter changes

3Ease of operation

If multiple penetrations are added to the blast pot for wet blasting, then fluid delivery is improved, but structural integrity and safety ratings are compromised

Engineering Contradiction:
Improvefluid deliveryVSAvoidstructural integrity
Core Design Contradiction:
Ease of operationVSStrength

Solution Approach 1:

The existing penetrations in the blast pot are designed to serve multiple functions - originally intended for dry blasting operations, they are now configured to also accommodate wet blasting components. The fluid manifold system utilizes these existing openings to introduce water and slurry without requiring additional penetrations, thereby maintaining the blast pot's structural integrity and safety ratings while achieving wet blasting capability

AI summary

A dry to wet abrasive blast machine conversion kit and method usable to convert an existing blast pot configured for sand blasting for use in wet abrasive air blasting includes a multi-function fluid manifold, and a control panel attachable to the blast pot to effectuate a first hydraulic circuit, a second hydraulic circuit, and a pneumatic circuit. The dry to wet abrasive blast machine conversion kit installs to the existing blast pot as is, and therefore enables conversion for wet abrasive blasting without additional penetrations through the blast pot envelope which might otherwise compromise manufacturer warranty and use ratings.
