LED Valve Position Indicator for Clear Open-Closed Status
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
It is difficult to determine the position of valves, such as ball, butterfly, needle, and gate valves, from the location of their actuators, leading to a need for an improved valve position indicator that effectively communicates the valve's position.
Innovation Solution
A valve position indicator system featuring an indicator cover with LED lights arranged around its rim, coupled with a sensor that communicates the valve's position to the LED lights, allowing for clear indication of the valve's open or closed state through illumination patterns.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Difficulty of detecting and measuring
If traditional valve actuators are used without position indicators, then the device complexity is reduced, but the ability to detect and communicate valve position deteriorates
Solution Approach 1:
The patent introduces an intermediary indicator system that includes LED lights and a sensor. The sensor detects the valve position and communicates this information to the LED indicator, which visually displays the position status. This intermediary system bridges the gap between the actuator and the operator, making position detection easy without requiring direct observation of the valve mechanism.
Solution Approach 2:
The patent replaces traditional mechanical position indicators with an optical system using LEDs and electronic sensors. Instead of mechanical linkages or visual mechanical cues, the system uses electronic sensing and optical signaling to indicate valve position, thereby improving detection capability while keeping the system relatively simple.
2Loss of information
If no visual indication system is provided, then the device complexity is minimized, but the communication of valve position to operators deteriorates
Solution Approach 1:
The patent uses color-changing LED lights to communicate valve position information. Different colors indicate different position states (e.g., green for open, red for closed). This visual color-coding system effectively transmits position information to operators without requiring complex displays or interfaces, minimizing information loss while keeping the system simple.
Solution Approach 2:
The LED indicator serves as an intermediary that converts internal valve position data into visible visual signals. The sensor captures position information and the LED translates it into color-coded visual feedback, effectively communicating valve status to operators without exposing complex internal mechanisms.
3Object-affected harmful factors
If the valve position indicator is placed far from the valve body, then operator safety is improved, but the ability to detect valve position deteriorates
Solution Approach 1:
The patent uses optical signaling (LED lights) and electronic sensing instead of mechanical indicators that would require close proximity. The sensor can detect valve position remotely through non-contact means, and the LED provides visible feedback from a distance, allowing operators to safely observe valve status from greater distances without sacrificing detection accuracy.
