Solution Overview
Problem
Existing fluid consumption meters face challenges in accurately detecting sound in piping systems due to interference from other electronic modules, which can affect the signal-to-noise ratio and hinder precise leak detection.
Innovation Solution
A fluid consumption meter equipped with a control device that includes a sound detection module, where at least one further electronic module not required for sound detection is deactivated to reduce interference, thereby enhancing sound detection properties.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple electronic modules are activated in the fluid consumption meter, then the device functionality is enhanced, but the sound detection precision deteriorates due to interference and noise from other modules
Solution Approach 1:
The patent segments the operational timeline into distinct phases: sound detection phase where only the sound detection module is active, and other phases where additional modules can be activated. This temporal segmentation allows the system to maintain both high sound detection precision and comprehensive device functionality without mutual interference.
Solution Approach 2:
The control device implements periodic action by cyclically activating different modules based on operational requirements. During sound detection periods, interfering modules are deactivated, then reactivated for their specific functions, creating a periodic pattern of activation that resolves the contradiction between functionality and precision.
2Reliability
If the sound detection module operates continuously, then the leak detection capability is improved, but the energy consumption increases and interference from other modules persists
Solution Approach 1:
The sound detection module operates periodically rather than continuously, activating only when leak detection is required. This periodic operation reduces energy consumption while maintaining reliable leak detection capability when needed, and allows other modules to operate during non-detection periods.
Solution Approach 2:
The control device preliminarily determines when sound detection is required based on operational conditions, then activates the sound detection module only during those specific periods. This preliminary assessment enables energy-efficient operation while maintaining detection reliability when conditions warrant it.
