Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional water and gas meters lack effective detection and alert mechanisms for reverse flow conditions, which can lead to inefficiencies and potential damage if not promptly addressed.
Innovation Solution
A solid-state register (SSR) system is implemented in meters, equipped with a microcontroller that accumulates reverse flow data over a time period and provides alerts when the accumulated amount exceeds a threshold, using magnetic flow sensors and optical sensors to detect flow direction and conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional mechanical registers are used in meters, then the structure is simple and easy to manufacture, but reverse flow detection and alerting capabilities are lacking
Solution Approach 1:
The patent replaces the conventional mechanical register with a solid-state register (SSR) that uses electronic sensors, a microcontroller, and digital processing to detect and monitor reverse flow conditions. This substitution enables sophisticated reverse flow detection algorithms and alerting capabilities while eliminating mechanical wear and tear, directly resolving the contradiction between improved reliability and increased device complexity.
Solution Approach 2:
The patent implements a feedback mechanism where the solid-state register continuously monitors flow direction, accumulates reverse flow data, compares it against threshold values, and triggers alerts when reverse flow exceeds acceptable limits. This closed-loop feedback system provides active reverse flow management, transforming the passive mechanical register into an intelligent monitoring system that proactively detects and reports reverse flow conditions.
2Measurement precision
If solid-state register with reverse flow detection is implemented, then reverse flow detection accuracy is improved, but manufacturing complexity and cost increase
Solution Approach 1:
The solid-state register is designed as a multi-functional device that not only measures forward flow accurately but also detects reverse flow, accumulates reverse flow data over time periods, compares against configurable thresholds, and generates alerts. This universal design consolidates multiple functions into a single device, improving measurement precision for reverse flow while managing manufacturing complexity through integration rather than adding separate components.
Solution Approach 2:
The patent employs parameter changes by using a microcontroller to dynamically configure threshold values, time periods, and alert conditions based on specific meter types and installation settings. This programmable approach allows the same solid-state register hardware to be adapted to different applications, achieving high measurement precision without requiring custom-manufactured devices for each scenario, thereby easing manufacturing constraints.
3Reliability
If reverse flow alerting system is added to meters, then operational reliability is improved, but device complexity increases
Solution Approach 1:
The patent merges the reverse flow detection, data accumulation, threshold comparison, and alert generation functions into the existing solid-state register unit. By integrating these functions within a single microcontroller-based device rather than adding separate external components, the system improves operational reliability while minimizing the increase in overall device complexity. The alerting system becomes an embedded feature of the register rather than an add-on subsystem.
