Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Communication between operators in remote sandblasting operations is difficult due to distance and environmental factors, posing safety and production hazards.
Innovation Solution
A multi-functional communication system with integrated remote signaling controllers, dead man switches, and wireless communication, allowing operators to send and receive alerts and commands through visual and audio signals, even in environments with reduced visibility and audio range.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If operators are positioned at remote locations for sandblasting operations, then operational flexibility and safety are improved, but communication capability between operators deteriorates
Solution Approach 1:
The patent introduces an intermediary communication system consisting of remote signaling controllers, display consoles, and audio alarms that mediate between the remote nozzle operator and the pot operator. This intermediary system transmits operational signals and alerts across the distance barrier, enabling effective communication without direct line-of-sight or proximity between operators.
Solution Approach 2:
The patent replaces direct human-to-human communication (which requires proximity and line-of-sight) with an electrical/electronic signaling system. The mechanical system of operators standing near each other to communicate is substituted with an electrical signaling network that can transmit information across remote distances through wired or wireless connections.
2Adaptability or versatility
If remote signaling controllers are equipped with multiple functions (communication, warning, alarm, control), then system versatility is improved, but device complexity increases
Solution Approach 1:
The patent applies multi-functionality by designing remote signaling controllers that integrate multiple functions into single devices. The controllers simultaneously provide communication capabilities, warning signals, alarm functions, and operational control, allowing one device to perform multiple roles that would traditionally require separate systems.
Solution Approach 2:
The patent merges previously separate functions (communication devices, warning systems, alarm systems, and control mechanisms) into integrated remote signaling controller assemblies. By combining these functions into unified devices, the system reduces the number of separate components needed while maintaining comprehensive operational capability.

AI summary
An independent safety warning and integrated notification system for remote operators that require an operator of equipment to be remotely positioned in relation to the blasting pot operator. A notification switch assembly is remotely secured to an existing sandblast hose adjacent the blasting nozzle with an integrated deadman switch allowing the blasting nozzle operator to communicate critical information to the blasting pot operator who controls the blasting supply operation. A combination of warning and notifications including lights and visual display with audible remote alarm assemblies and remotely positioned warning light alarm positioned near the blast pot operator for notification that a prescribed predetermined action has been requested by the blast nozzle operator or an emergency situation exists. A remote single monitoring display panel and notification is provided for use in blast containment areas and a remote monitoring display allows for overseeing the operation via digital communication criteria.
