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

VSEngineering 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

Engineering Contradiction:
Improveremote control capabilityVSAvoidsafety of manual reset operation
Core Design Contradiction:
Ease of operationVSReliability

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

Inventive Principle:
Principle #10Preliminary action

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

Inventive Principle:
Principle #24Intermediary (Mediator)

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

Engineering Contradiction:
Improvesafety assessment capabilityVSAvoidmaintenance response time
Core Design Contradiction:
ReliabilityVSLoss of time

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

Inventive Principle:
Principle #10Preliminary action

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

Inventive Principle:
Principle #15Dynamics

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

Engineering Contradiction:
Improvefluid flow management speedVSAvoidunintended reset risk
Core Design Contradiction:
ProductivityVSObject-affected harmful factors

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

Inventive Principle:
Principle #10Preliminary action

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

Inventive Principle:
Principle #23Feedback
