Solution Overview

Problem

Existing gas meters lack the capability to efficiently control and optimize gas consumption, leading to potential overuse and increased bills, especially in scenarios where users fail to pay their gas bills.

Innovation Solution

A gas counter equipped with a measurement system, a valve, and a processing unit that analyzes gas consumption data to detect operating phases of predetermined systems, such as boilers and water heaters, and cuts the gas supply when cumulative consumption exceeds predetermined thresholds.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of energy

If gas consumption is monitored and controlled by cutting off gas supply when thresholds are exceeded, then gas consumption is reduced and bills are optimized, but user convenience is reduced due to gas cut-offs

Engineering Contradiction:
Improvegas consumptionVSAvoiduser convenience
Core Design Contradiction:
Loss of energyVSEase of operation

Solution Approach 1:

The patent applies local quality by making the gas cut-off selective rather than universal. The system identifies specific appliances (predetermined systems) and applies cut-off only to them when their individual consumption exceeds thresholds, while leaving other appliances unaffected. This localized approach reduces overall gas consumption without completely disrupting user convenience, as users can still operate non-targeted appliances normally.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The system dynamically adjusts gas supply based on real-time consumption patterns. Rather than a static cut-off approach, the processing unit continuously monitors gas consumption, detects operating phases of specific appliances, and dynamically controls the valve to cut-off gas only when and where thresholds are exceeded. This dynamic control optimizes energy reduction while adapting to user needs throughout the day.

Inventive Principle:
Principle #15Dynamics

2Reliability

If traditional motorized valve cut-off is used, then gas supply can be stopped for non-payment, but the system lacks capability to optimize consumption for individual appliances

Engineering Contradiction:
Improvegas cut-off capabilityVSAvoidconsumption optimization capability
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent implements feedback by using the processing unit to continuously monitor gas consumption measurements from the measuring device, compare actual consumption against predetermined thresholds for specific appliances, and automatically adjust the valve control accordingly. This closed-loop feedback system ensures reliable cut-off execution while providing the adaptability to optimize consumption for individual appliances based on their specific usage patterns and thresholds.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The system performs self-service by automatically detecting operating phases of predetermined appliances and autonomously controlling gas supply without requiring manual intervention. The processing unit analyzes consumption data, identifies when specific appliances are operating, and automatically triggers cut-off decisions, making the system both reliable in execution and adaptable to different consumption scenarios.

Inventive Principle:
Principle #25Self-service

3Productivity

If gas cut-off is applied universally when daily thresholds are exceeded, then payment compliance is enforced, but user purchasing power is reduced without targeted optimization

Engineering Contradiction:
Improvepayment complianceVSAvoiduser purchasing power
Core Design Contradiction:
ProductivityVSQuantity of substance

Solution Approach 1:

The patent applies segmentation by dividing the gas consumption monitoring into separate tracks for different predetermined appliances. Instead of treating all gas consumption uniformly, the system segments monitoring by appliance type, applies specific thresholds to each segment, and controls cut-off on a per-appliance basis. This segmented approach enforces payment compliance through targeted cut-offs while preserving user purchasing power by allowing continued operation of non-targeted appliances and providing granular control over consumption.

Inventive Principle:
Principle #1Segmentation

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

The solution effectively reduces gas consumption and associated bills by cutting the gas supply only during specific use cases, thereby helping users limit their gas usage without penalizing them.

Implementation Method 1

an ultrasonic measuring device comprising an upstream transducer (network side) and a downstream transducer (installation side). Each transducer successively acts as an emitter and a receiver of ultrasonic signals. The upstream transducer thus emits an ultrasonic signal into the internal conduit, which is received by the downstream transducer after having traveled a predefined path (of perfectly controlled length) in the gas.

Methodology Applied
Scientific EffectUltrasonic signal propagation: Ultrasound
