Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If magnetic pulse reading is used, then the gas meter reading can be obtained, but the reading accuracy deteriorates due to interference and discrepancies

Engineering Contradiction:
Improvereading accuracyVSAvoidreading reliability
Core Design Contradiction:
Measurement precisionVSReliability

Solution Approach 1:

The patent replaces the magnetic pulse reading system with an optical reading system using a camera. The camera captures images of the gas meter display, and image processing algorithms extract the reading data. This substitution eliminates the interference and discrepancies associated with magnetic pulse reading, providing more accurate and reliable measurements.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent creates an optical copy (image) of the gas meter display rather than directly reading magnetic pulses. The camera captures the visual state of the display, and this copy is then processed to extract the reading. This copying approach avoids the direct contact and interference issues of magnetic pulse reading.

Inventive Principle:
Principle #26Copying

2Productivity

If existing gas meter reading systems are used, then the gas consumption can be tracked, but real-time monitoring capability is lost

Engineering Contradiction:
Improvereal-time monitoring capabilityVSAvoidtime delay in consumption data
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The patent implements continuous optical monitoring of the gas meter display through the camera system. The system can capture images at regular intervals, enabling continuous tracking of gas consumption in real-time. This eliminates the time delays associated with periodic manual readings or pulse-based systems.

Inventive Principle:
Principle #20Continuity of useful action

Solution Approach 2:

The system incorporates feedback mechanisms where the captured images are processed to extract consumption data, which is then transmitted and analyzed. This feedback loop enables real-time monitoring and allows for immediate detection of abnormal consumption patterns or leaks.

Inventive Principle:
Principle #23Feedback

3Adaptability or versatility

If magnetic pulse reading is used, then the gas meter data can be read, but leak detection capability is lost

Engineering Contradiction:
Improveleak detection functionalityVSAvoidsystem complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent integrates multiple functions into a single optical reading system. The camera-based system not only reads the gas meter display but also detects gas leaks by capturing images of the gas meter area and analyzing them for leak indicators. This multi-functionality is achieved without significantly increasing system complexity, as the same optical components serve multiple purposes.

Inventive Principle:
Principle #6Universality (Multi-functionality)

4Productivity

If manual gas meter reading is used, then the reading process is simple, but labor costs and time consumption increase

Engineering Contradiction:
Improvereading efficiencyVSAvoidtime for manual reading
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The system enables self-service reading by automatically capturing and processing the gas meter display images. The optical reading system performs the reading function without requiring manual intervention, allowing the system to serve itself in extracting consumption data. This eliminates the need for trained readers and reduces time consumption significantly.

Inventive Principle:
Principle #25Self-service
