Boiler Water Level Display for Intuitive Safety Monitoring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional steam boiler systems face challenges in maintaining adequate water levels, leading to potential catastrophic failure due to insufficient water, which existing monitoring methods like float devices may not adequately address, necessitating frequent testing of safety procedures.
Innovation Solution
A boiler controller with a data display featuring a background indicator and compound level indicator that visually communicates boiler safety levels through color changes, providing intuitive alerts and detailed information on water levels, and outputs signals via USB, Modbus, and 4-20 mA protocols.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional float devices are used to monitor water level, then the system can detect low water levels, but the system requires frequent testing of safety procedures and lacks intuitive visual communication of safety levels
Solution Approach 1:
The patent applies color changes in the background indicator to communicate different boiler safety levels. The background indicator changes colors (e.g., green for safe, yellow for caution, red for dangerous) based on water level conditions, providing intuitive visual communication that eliminates the need for frequent testing and improves operational clarity while maintaining monitoring reliability.
Solution Approach 2:
The patent adds a visual dimension to water level monitoring by implementing a background indicator that spans across the display and changes appearance based on safety levels. This transforms the monitoring system from simple numerical or binary indication to a multi-dimensional visual communication system that conveys safety status at a glance.
2Loss of information
If detailed water level information is provided through alphanumeric display, then precise status information is available, but the system lacks quick visual alerts for safety levels
Solution Approach 1:
The patent segments the display information into two distinct components: a background indicator for quick visual safety level alerts and an alphanumeric status indicator for detailed water level information. This segmentation allows operators to immediately grasp safety status through the background color while maintaining access to precise numerical data when needed, eliminating the trade-off between information completeness and response time.
Solution Approach 2:
The background indicator uses color changes to provide immediate visual alerts about boiler safety levels. This allows operators to quickly assess the current safety status without needing to read or interpret alphanumeric data, significantly reducing response time while the alphanumeric display remains available for complete information when required.
3Illumination intensity
If the background indicator spans a large area of the display, then visual communication of safety levels is enhanced, but the area available for other display information is reduced
Solution Approach 1:
The patent segments the display area into distinct zones: the background indicator occupies the majority of the display area for maximum visual impact, while a dedicated alphanumeric status indicator area provides detailed information. This segmentation allows the background indicator to span a large area for enhanced visibility without completely sacrificing the space needed for other display information.
Solution Approach 2:
The patent applies local quality by making the background indicator visually dominant across most of the display area to ensure safety level communication is the primary focus, while allocating specific localized areas for alphanumeric status information. This ensures that the most critical safety information receives the most visual attention while maintaining access to detailed data.
Data Source
AI summary
Disclosed, in one general aspect, is a boiler controller that includes an input for receiving a boiler water level signal, a screen having a data display that displays information. The data display includes an alphanumeric status indicator area responsive to the water level signal and operative to display status information about the water level signal in alphanumeric format, and a background indicator that extends around the alphanumeric status area and is operative to display a visual treatment that communicates different boiler safety levels. Disclosed in another general aspect is a boiler controller that includes an input for receiving a boiler water level signal and a compound level indicator that includes a vertically extending level-indicating device, a baseline reference level indicator positioned along the vertically extending level level-indicating device, and a visual treatment for the vertically extending level-indicating device that communicates different boiler safety levels. Water level outputs are also disclosed.
