Sealed Containment Doors for Blasting Media Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing containment systems for surface treatment expose operators to hazardous conditions as they require direct access to the treatment area, and they lack the ability to maintain a sealed environment effectively, leading to contamination of the surrounding area.
Innovation Solution
A portable containment system with sealable openings at both ends, featuring a housing with translucent panels and a piston mechanism for door operation, allowing the operator to remain outside while maintaining a sealed treatment area through negative pressure and facilitating the collection and recycling of blasting media.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the operator is located inside the containment area to treat the surface, then the treatment operation can be performed directly, but the operator is exposed to hazardous conditions including blasting media, contaminants, and debris
Solution Approach 1:
The containment system is divided into separate zones: the treatment area where blasting occurs and the operator area where the operator controls the system. This segmentation allows the operator to remain outside the hazardous treatment zone while still performing the treatment operation through coordinated control of the blasting media delivery system and containment system movement.
Solution Approach 2:
The patent introduces an intermediary control system that allows the operator to control the blasting operation and containment system from a safe distance. The operator manipulates controls that regulate media delivery, containment system positioning, and door operations, serving as a mediator between the operator and the hazardous treatment environment.
2Object-affected harmful factors
If the containment system is completely sealed to prevent contamination, then environmental protection is improved, but the operator cannot access the treatment area for operation
Solution Approach 1:
The containment system incorporates dynamic door mechanisms that can open and close at both ends of the treatment area. During operation, the doors remain closed to maintain sealing and prevent contamination. The system transitions between sealed and accessible states, allowing operator intervention only when necessary for setup or maintenance, while maintaining environmental protection during the actual blasting operation.
Solution Approach 2:
The operator uses the intermediary control system to manage the containment doors and blasting operation without direct physical access to the treatment area. This allows the operator to maintain the sealed environment while still controlling all aspects of the treatment process through remote operation.
3Ease of operation
If the containment system allows operator access for direct treatment, then operational control is improved, but blasting media and debris escape into the surrounding environment
Solution Approach 1:
The system segments the treatment process into controlled phases: setup phase where doors are open for operator access, and treatment phase where doors are closed to contain media and debris. This temporal and spatial segmentation allows both operator control and environmental protection to be achieved at different stages of the operation.
Solution Approach 2:
The containment system maintains continuous sealing during the blasting operation, ensuring that blasting media and debris remain contained throughout the entire treatment process. The operator maintains continuous control through the intermediary system, and the sealed environment continuously prevents escape of harmful materials without requiring operator entry into the treatment zone.
4Adaptability or versatility
If the containment system is designed to be portable and movable, then transportability to remote sites is improved, but the sealing effectiveness may be compromised
Solution Approach 1:
The containment system features dynamic sealing mechanisms including movable doors with seals that maintain effective sealing despite the system's mobility. The doors can be positioned and sealed at various locations along the treatment area, allowing the portable system to maintain reliable sealing effectiveness while being transported and repositioned to different sites and orientations.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system effectively contains blasting media and debris within the treatment area, preventing environmental contamination, allowing for safe operation and efficient recycling of materials, while enabling the operator to maintain a safe distance and improve treatment efficiency.
Implementation Method 1
The pair of doors at each opened end are respectively supported by a pair of piston mechanisms which facilitate movement of the doors between the opened and closed positions
Implementation Method 2
A thickness of resilient material is supported by and extends along the inwardly facing surface of each door so as to achieve an air tight seal between the door and the object to be treated
Implementation Method 3
The enclosed treatment area is maintained at a negative pressure with respect to the surrounding environment so as to contain the blasting media and prevent airborne contamination

AI summary
A treatment and containment system for treating an elongate object to be treated. The system comprises surface treatment equipment or device for treating a portion of the elongate object to be treated; a housing defines an enclosed treatment area and separates the enclosed treatment area from an operator of the surface treatment equipment or device, and the housing is opened at opposed ends thereof; each opposed opened end of the housing accommodates a pair of movable doors which seal against the elongate object to be treated and thereby closing each opposed opened end of the housing; the housing has an access aperture therein through which the surface treatment device passes and communicates with the enclosed treatment area, and the access aperture facilitates manipulation of the surface treatment device within the housing; and a transparent viewing aperture facilitates viewing of the elongate object to be treated by the operator.
