Fluid Intercepting Valve With Remote Control And Manual Reset
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fluid intercepting devices require manual reset by a technician at the device location, posing safety risks as the reset can be inadvertently triggered remotely without assessing the technician's situation, and there's a need for remote control functionality to manage fluid flow, especially in hard-to-reach areas for safety and maintenance purposes.
Innovation Solution
A fluid intercepting device with remote control capabilities and manual reset options, featuring a shaft mechanism with a spring and holding means for shifting between open and closed configurations, and remote control means for safe operation, including anti-reset features to prevent unintended manual resets.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If remote control means are added to enable remote operation of the intercepting device, then the ability to control fluid flow from a distance is improved, but the risk of inadvertent reset and safety hazards to technicians worsens
Solution Approach 1:
The device requires preliminary manual activation by a technician before remote reset can be executed. The technician must physically access the device, activate the manual reset function, and only then can remote control operations be performed, ensuring safety assessment before remote intervention
Solution Approach 2:
A control unit acts as an intermediary between the remote control means and the intercepting device. The control unit receives signals from remote control means, verifies proper activation conditions, and then transmits controlled signals to the intercepting device, preventing direct and potentially unsafe remote activation
2Reliability
If the device requires manual reset by a technician at the device location, then the technician can inspect and repair piping before reset, but the working conditions become highly dangerous and time-consuming
Solution Approach 1:
The system allows preliminary remote shutdown operations to be performed immediately upon detecting fluid flow issues, without requiring technician presence. This separates the urgent shutdown function from the safer reset function, reducing response time while maintaining safety
Solution Approach 2:
The device transitions from a static manual-only reset system to a dynamic system with multiple operational modes: immediate remote shutdown for urgent situations, and controlled manual or remote reset for non-urgent situations, adapting the reset procedure to the urgency and safety conditions
3Productivity
If remote control means are implemented without manual activation requirement, then the response time for fluid flow management is improved, but the risk of unintended operation and technician safety worsens
Solution Approach 1:
Manual activation by a technician serves as a preliminary safety check before remote reset operations can commence. This ensures that the system is only reset when a technician has verified safe conditions, preventing unintended operations while allowing rapid remote execution once activated
Solution Approach 2:
The system incorporates feedback mechanisms where the control unit monitors activation status and operational conditions before executing remote reset commands. This feedback loop ensures that reset operations only occur when proper activation conditions are met, preventing unintended operations
