Portable Monitor Control System with Trigger Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Portable fluid monitors often move from their intended position due to insufficient restraint, causing the fluid stream to be directed undesirably, as the reaction force from fluid exit can overcome the frictional resistance, leading to unintended movement.
Innovation Solution
A portable monitor control system that includes a trigger mechanism operably coupled with the fluid inlet, which reduces fluid flow when the monitor moves, thereby mitigating the opposing reaction force by using a pivotable arrangement with a trigger pin, restrictor component, and lever arm to automatically adjust fluid flow based on rotation, allowing for stabilization and reduced movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the monitor is left unrestrained to improve ease of operation, then the monitor can be positioned more freely, but the monitor moves from its desired location due to reaction force
Solution Approach 1:
The system automatically detects monitor movement through the trigger mechanism and self-corrects by reducing fluid flow to mitigate reaction force, eliminating the need for manual intervention or external tethering structures
Solution Approach 2:
The trigger mechanism provides continuous feedback on monitor position, and the control system uses this feedback to automatically adjust fluid flow rate, creating a closed-loop control system that maintains position stability
2Productivity
If fluid flow rate is increased to improve productivity, then more water can be delivered to the fire, but the reaction force increases causing monitor movement
Solution Approach 1:
The system dynamically adjusts the fluid flow rate based on real-time monitor position feedback, allowing high flow rates when stable and automatic reduction when movement is detected, optimizing both productivity and stability
3Stability of the object's composition
If a tethering structure is added to improve position stability, then the monitor can be restrained, but the device complexity increases
Solution Approach 1:
The patent replaces external mechanical restraint systems (tethers, anchors) with an internal control system that uses fluid flow modulation to achieve position stability, simplifying the overall system
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 reduces the reaction force by adjusting fluid flow, preventing the monitor from moving further from its set position, ensuring accurate targeting and stabilization, even without a tether, by automatically reducing fluid output when the monitor rotates away from its center.
Implementation Method 1
the trigger pin normally biased toward the fluid inlet by a biasing component
Implementation Method 2
the reaction force associated with the fluid exiting the monitor

AI summary
One or more techniques and/or systems are disclosed that can provide for a portable monitor control. A movement detection triggering system can be disposed between a fluid inlet and the body of the portable monitor, and may be able to restrict or reduce fluid flow when the monitor is moved from its desired position. A trigger arm can be coupled with the inlet, and, when the inlet is pivoted away from a set position, the trigger arm is also moved, which triggers another portion of the control system. A trigger pin is released, which may allow a lever to rotate, allowing a restrictor component to move into place in the fluid flow path, thereby restricting fluid flow.
